Hello,

I need some help. I have been building systems for several years and decided to build a file server for myself and my friends. I used an athlon xp 300 400fsb i had lying around and a nforce 2 board i had. I have a raid array ide with 4 drives. I have 2 drive also on 1 of the ide channel. I also have a dvd burner and a fx5200 graphics card. I have a generic 500 watt power supply from bestbuy. The computer will not boot at fill athlon xp 3000 speed. I have to lower the fsb to 175 to get it to boot. All my tests tell me the power supply is just maxed out. Does anyone have any recommendations on what I should buy? Are amps the thing to look at? Voltage? Watts ?

just buy another cheap PSU and use this one to power up the 6 HDs!

use your original 500w to power up the MB etc.

otherwise you will be buying a new and costly 600w or so.

Try booting the system with only 1 or 2 disks instead with the processor at 200/400 FSB first. I have a sneaking suspicion that there just may be an issue with the proc running at that speed. If it does boot fine, then I'd say wun911's suggestion of a second ps is a fine one if you have the space. There are many guides out there on how to get one powersupply to start another, generally dealing with wiring up a electronically-controllable switch to the two pins on the ps you usually short to start it (usually handed by the mobo, of course)

I hate cheap power suplies - they seem to enjoy blowing up and killing as many components as possile on their way out. If you haven't done it yet, bmouring's stip-it-down and fire it up advice is good. But a single, good quality ~500 watt PS should run this rig. And they don't have to be so expensive:

I've run a 4400+, X1900XT, 2 opticals and 4 HDs with that PS. It is a single 12V rail that is conservatively rated at 26A. $77 after MIR = bargain. If you don't think 520 watts is sufficient, then I'd jump up to something like:

or:

I realize that there are many solid power supplies other than OCZ, but their current MIRs are very good deals. That Gamextreme has guts (as it should for that price).

Hello,

I have to thank you for the replies on a Sunday! I wish I could do two power supplies but I have invested so much in my new case that I really can't. So I will be shopping for a new PSU. Is there any Amp'age on certain rails I should be looking for. IS higher or lower Ampage better?
June 4, 2006 2:22:36 PM

I'd want a good quality PS, but I personally don't think you need a huge supply just because you have 6 disks. I think any good quality 400W supply will be fine, so I agree that I would try to power up the machine without all the disks first and see what happens. That machine isn't going to be drawing that much power at idle and I agree there is probably something else going on instead of a power issue. If it is a power issue, it's probably not total power, but quality of the power that is the problem.

Higher +12V amperage is better because each component adds to the current load on the PS. If the unit is designed well, you can get an advantage by having multiple 12V rails with a high total 12 current capacity. So look at the specifics of # of rails and total +12V current capacity - and look at the ripple too (lower is better).

What brand of PSU are you using now?

Almost any Antec, OCZ, or Thermaltake above 450 Watts should be enough for that.

best idea so far.

if u can get the 2nd PSU not a cheapo one maybe an Antec SmartPower 350w or a Forton source their cheapest and run ur mobo off that.
June 4, 2006 7:22:40 PM

I think you're spending way too much and much more PS than you possibly need, but it's your money. :?

Would this be Good?

It is good, and the FSP is no doubt better... but I have to agree 100% w/ Pain - that is overkill!!
Check out my fileserver specs:

Aspire X-Navigator w/ ATX-AS500W-BK
P4 2.4 northwood w/ Tyan Trinity S2099GNN/
2x512mb transcend DDR266 CL2
10xIDE hdds 80gb~300gb
2xpci ide raid
1xdvdrw,1xcdrw
1xcompaq pci sound



So the lowly Aspire ATX-AS500W-BK is able to handle it no problem, the specs are similiar to this (mine has only single +12v@34A rail)

and this thing is going strong for over 18months 24x7 and only shut down when I go on vacation about 3 times a year for a week at most. Prior to getting the X-nav w/ the 500w I was using the full-tower dual PSU above :p 

Since you won't be using it for games and it is an older XP system you can probably get away with something less on the +12 you were looking at and maybe look for something with at least +5v@30A or better.

The OCZ ModStream OCZ52012U mentioned is a nice unit at $100 shipped, it is a bit pricey - the $20 MIR definitly helps.

I noticed Newegg has their $50 rebate on this unit:
COOLER MASTER eXtreme Power ATX12V 600W for $99 shipped w/ $50 MIR
which I am not too fond of since it really is a 500w unit marketed as 600w, the MIR puts it in it's proper price range. It is a decent 500w unit with +5v@30a so that may work for you - if you can wait it out for the MIR.

Some other ones I noticed on newegg that have high +5v that may work just as well, but I would probably go w/ one of the above over these:

Thermaltake Silent PurePower TT-420AD(DUAL FAN) ATX 420W $48 shipped
JUST PC JPC-P4SF550C 550W $60 shipped
Thermaltake Silent Purepower W0014RU ATX 480W $70 shipped
ASPIRE ATX-AS520W Silver $69 shipped w/ $10 MIR
ASPIRE ATX-AS520W BLUE $69 shipped
RAIDMAX AURORA RX-580F $69 shipped
Rosewill RP550 ATX 550W $70 shipped
Rosewill RP550-2 ATX 2.01 550W $75 shipped
KINGWIN ABT-520MM ATX 12V 2.0V 520W $75 shipped

I actually used the TT-420AD in my linux fileserver and game rig (when it was A64-3400 / 9800 pro OC'd to replace the dual PSU mid-tower I was using - was on sale at newegg, and not such a bad performer.
June 4, 2006 10:20:28 PM

silverstone makes a product that is 2x 480w psus.

its 2 psus in the size of 1 psu. you need 2x plugs to plug it into the wall.

a basic quad 12v rail off the bat....

it will fit in your case....

and its made for pplz with zillions of hds

pity you couldnt just buy a second psu......... saves $$$

I saw that a couple of months ago when I was on my GPU/arc welding quest. I was wondering what the heat and sound of that big guy was like. One review had the ripple kinda high on the +12V and that scared me off. I liked the 2 plugs bit...

doolittle hows the air flow and PSU on the aspire, i like the case but not the PSU, maybe a short little riview for me, i've only found 1 review on the X-navigator but none on its PSU.
June 5, 2006 2:09:01 AM

You guys are funny, 450watt or more? Yeah right, get a solid 300watt for cheap and you're set. Here's my 8 disk system, all older drives except the two maxtor 200's, a p4 2.4, and a radeon something or other (64meg DDR):

June 5, 2006 2:33:40 AM

I find it hard to beleive that your PSU can't handle it. It should be more than powerful enough for those specs. You could get a quality 400W psu and it would be more than sufficient for that setup. FSP makes a good psu.
June 5, 2006 3:24:24 AM

On the PSU itself the fans are actually low-speed (even at full setting) so it is relatively quiet, but a bit light on the airflow - and the exhausted air is a bit warmer than I like.
The voltages are all in spec and it is stable at idle and load, so I can't complain - but it would have been nice to get the case w/o any PSU. And it does look cool 8)

The saving grace is the excellent case airflow - which was messed up when I got the case, both the side and rear fans were blowing in the wrong directon so I had to reverse that as well as add all the fans to the hdd's so they would not overheat. It is a bit loud, but I would much rather have a loud case than a hot case :p 
June 5, 2006 3:38:47 AM

Well the OP's system is XP 3200, usually socket A systems have the core CPU volts draw off the +5v rail so that will suck 15A or more so a 300w PSU may work, I say double it to at least 30A since the rail is usually shared with the +12.

I would definitly not use an AGP card with an external power connector with an XP3200 and a 300w unit and that many HDDs...
June 5, 2006 3:47:37 AM

I used to have an athlon xp 2400 in there, no prob, good psu's are overrated to begin with. I've had 3 10k rpm scsi drives and an adaptec raid array1000 scsi controller on that exact machine at the same time as the 8 other hd's.

A coolmax or other crappy psu will blow up with that, but a high quality one can handle it, that ever ps I have in there doesn't even get warm.

Believe it or not, that system isn't that power hungry. An Athlon XP and a 5200 aren't bad, and the hard drives don't take up as much as you might think. Any GOOD BRAND 500w should handle it. BTW, shop online. Bestbuy etc are complete rip-offs.
June 5, 2006 4:37:29 AM

that is quite a difference over my old game rig / fileserver conversion, was an XP2800 w/ 9500 pro and the trusty antec 300w unit failed to post after I added the 6th hdd.
Luckily it was in the full tower so I was able to drill out the template for the 2nd psu and install it neatly (almost)...

I never thought to remove the GPU to see if it would work since I wanted to lan game w/ it...
June 5, 2006 4:57:07 AM

I'd say that your antec 300 isn't so good then, it was worn out, or you have bad power in your house :) 

I've got a 300watt running an athlon64 3000, 1 gig ram, 2 80gb sata hd's, radeon 9800 pro, 2 optical drives, and the previously mentioned scsi card and 3 scsi hd's.

Good 300's really can run alot, maybe everyone is just afraid to try with everyone saying "you need 450" or "get a 700 watter" or maybe they don't make good ones anymore, all of mine are over 4 years old (I have a couple more 300's in full 24x7 service, one on a dual PIII 1000.)

I do use a 600watt silverstone for my htpc and enermax 365 for the wifes. My personal machine has a rycom (generic) 500 and it's fully moderm, athlon 64 3700, 2 gig ram, 2 250gb hd's, 2 optical drives, radeon x1800xt.
June 5, 2006 5:06:48 AM

Sooo many far-kin HDs why not just get bigger capacity HDs.

Sell the old low capacity HDs use this to buy a couple of 350Gb HDs then you wont have the problem of "what PSU will suport 6 HDs!?"

Honestly 3 x 350Gb HDs should do the trick....

Someone is keeping way too much pron on thier comp. :) 
June 5, 2006 5:17:11 AM

I have over three terabytes in my house, almost all full thanks to my wife. Only around 60gig is pron :roll: and lets not bring up how many hd's I have running all day long 8O

edit: 1 terabyte is in a raid 5 and almost half of another is in various raid 1's, lots of hd's
June 5, 2006 6:43:14 AM

naa, my trusty antec still rocks - runs my dual pIII-1ghz linux workstation / secure gateway to this day. Had to get the 24-pin for the intel STL2 it was funny about not having that and the 6 pin aux AT style connector...
house power is good (although my o-scope probably need calibrating), ups is good (still good after a pair of new batteries).

After I added the 2nd 250w AT unit I only added a dozen hdds then ran out :(  was great until my bro needed a game rig I think I got the x-nav around then.

Any psu suggestions for OP?

:lol:  awesome!

I was forced to do that when my x-nav didn't have the capacity to hold a dozen hdd's and my optical drives :cry:  the smallest ones got the axe, the limit was 40gb and lower, and got a 300gb.

you know, a very large portion of that are dvdrips to watch on any pc in the house - mostly for the kids!
June 5, 2006 7:19:55 AM

.....Back to the original question and the best answer.
Just get a good quality PSU. IMO Fortron PSU's are $ for $ the best PSU's in existence, simply because the are so much cheaper(did I mention they are dirt cheap?) than PCP&C. Anyway, I have ran up to 5 HDD's w/ 3 optical drives, a geforce 6800, 5 PCI cards, 11 fans(one of which is a 92mm tornado,3 of which are TT Smartfan 2's), and a power hungry 3.2 Ghz P4 at the same time with no problems at all on a 530 watt Fortron. Most likely unless you run alot of other things in your PC, you could get by with like a 400-450 watt PSU, which at Newegg runs about $60(400 watt).

Hello Again,

Wow I was not sure even if anyone would right back. Thank you all for your responses. I would like to give some other info that may help. I am guessing it is the power supply that is the problem. It all started when i wanted to add another 200 gig drive i bought. I have a ide raid now on a pci card. I went to add in the drive in a generic sata plug i had open. Sense then I have had issues. It could be the CPU but sense i added the other drive i have had the problems. Sense i have pulled it out but it makes no difference. I can't get passed athlon 2200 speed basically or the system reboots. I can run prime 95 for days on 175 fsb. I push to 185 it crashes. Well looks like i will try to replace the power supply. The PSU i bought from bestbuy becuase my wife is a manager there and gets a nice discount :-).
June 5, 2006 11:33:03 AM

Hello All,

this morning I opened up my file server and I have the stats for the power supply in question.

Model - Dynex Dx-ps500w

Dc Ouput - +5v=40a +12v1=16a +3.3v=35a +12v2=18a -5v=0.5a 12v=0.5a +5vsb=2.5a

output watts 500w, +5v:180w

I copied this exactly from the sticker on the power supply. Please let me know if this any good. From what I have read the stats on this are strong and at best buy it retails for 130.00 US. Not what i paid with my wifes discount but still :-)

Here's my recommendation, the ENERMAX EG851AX-VH(W) FM EPS12V 660W. I've got this psu running a dual opty with 6 drives, 2 cdroms, gpu, 3ware raid, 3case fans, etc...nary a stutter, burp, or fart from it....voltages are stable, 4-12v rails, plenty of amps on each leg for whatever you need.

I learned long ago that one component not to cheap out on is the psu...I can appreciate getting the discount from Best Buy, but I've returned more parts I've bought from them than I've kept...PC Power & Cooling are really nice, but way overpriced all things considered, the Enermax suggested above would suit your needs...

Good luck!
June 5, 2006 1:11:43 PM

Wow! Its 235.00! Jesus! Naaa that is a little rich for my blood. I was looking at a PSU for 177.00 and i felt bad. Not sure what I am going to do. I am going to unplug some of the drives tonight and then see if it boots at full athlon xp 3000. That will tell me alot....either PSU or Chip. I am hoping its the PSU, socket A chips are more expensive now!
June 5, 2006 4:17:40 PM

Sorry pengwin but that's overkill, try this, much cheaper and very solid, I've used a couple in my brother's computers cause he's cheap :) 

http://www.newegg.com/Product/Product.asp?Item=N82E16817182018

You don't need quad rails for an application like this, it's crazy talk.

edit: typo on newegg, 12v rail 1 is 14amp and 12v rail 2 is 15amp not 5amp
June 5, 2006 4:29:44 PM

What is Quad 14v rails anyway??? LOL Sorry guys my power supply knowledge is very limited! I am curious.
June 5, 2006 4:33:24 PM

4 independent rails in the ps, this allows you to put one vid card on one rail, the 2nd vid card on second rail, and all other 12v stuff (hd's, opticals, etc) on the third rail, while the rest of the system uses the 4th rail.

Keeps amperage more manageable for high end systems. ABSOLUTELY NOT NEEDED for what you are doing. The dual rail I just suggested is overkill too, but you will feel better knowing all your hd's are on one rail and the 3000 is on the other :)

it seems like it should handle it, but I would not trust that brand to have honest power ratings...

Can she return it and exchange it for the Antec TruePower 2.0 480 it appears to be $136 and if she get's a 40% discount at least it should bring it down to "normal" prices... This way you at least have a decent unit and aren't stuck w/ the cheezey "dynex" brand PSU - that is a lot of $ to be lost :(

HD's use an average of 16 Watts after they spin up to speed...untill then they use about 48-50 Watts.

If you system will not run full fsb and your "cheep" PSU is 3 years old then the time has come to replace it.
The best investment you can make is to use a REAL PSU.
PSU's are almost always rated at an inside temp of 25C...unless you live in Alaska these power ratings are a joke.

As the temps go up the real power out goes down.
You should never feel HOT air comming out of your PSU.

PC Power & Cooling are rated at 50C,warrenty is 5 years and they will replace all caps if you send the unit to them for a low price.

I am going to try and take off all the drives and see what happens. This way I know for sure its the power supply. I will update you all tonight.

As for dynex, believe it or not they are not as bad as one would think. TO give you example, there blank dvd's are actually Ricoh lol. So I figured I would give it a shot. Well I will know tonight. At this point I am hoping its the power supply. I don't want to buy another athlon xp cpu they are not cheap at all.

Good 300's really can run alot, maybe everyone is just afraid to try with everyone saying "you need 450" or "get a 700 watter" or maybe they don't make good ones anymore


I think that there still are good 300 watt power supplies out there, just like there are lousy 500 watters. It's interesting to look at test data and how different sellers rate their product. All 300 watt power supplies are not created equal. A unit that can survive a big startup draw and operating at a relatively high temp will handle a loaded-up PC with just 300 watts. OTOH, after pushing things too far and getting burned, I've gone the way of providing huge overhead. The additional cost isn't that significant in the big picture. Even the ~$450 PCP&C is not extravagant for some rigs in my opinion. (I don't have one nor plans to build something that would justify one)

Not sure what you're getting at but over the years, Ricoh has produced exceptional quality goods. Not sure if they still are but around a decade ago, Ricoh was the high quality optical supplier to Sony's premium lines.

HD's use an average of 16 Watts after they spin up to speed...untill then they use about 48-50 Watts.


Our work group had a server maybe 10 years ago that typically ran 24/7 but if you had to restart, it sequentially spun up each drive and the controller software allowed the operator to set up the conditions. I haven't even looked to see if that capability exists in XP???

The best investment you can make is to use a REAL PSU.


Yer talking my language there.

Quote:
PSU's are almost always rated at an inside temp of 25C...unless you live in Alaska these power ratings are a joke.


You bet. Some makers are considerably more conservative in their wattage/current ratings than others, in part to be certain their unit can deliver in real world conditions. It's worth it to go look at nuts and bolts reviews. Having a PC bite it, like losing the mobo and CPU, for instance, just because your PS puked, is something that you'll remember a while. Trust me on this ye doubters out there (not you ZODude).

Lots of scsi rigs spin up sequantially (it's acutally a jumperable setting), all of mine do, as do the servers I maintain. Many bios's let you specify startup delays, usually for all HD's not individually, but that can reduce the strain by allowing all other components to level out then startup the disks.

Thanks for that info. I'll check the bios on my video box since it has a bunch of drives. I don't recall seeing it there, but I wasn't looking. I woulda swore our work group server set up the drive spinups in software for their PCI board.

If it was setup in software then it wrote it back to the firmware on the controller, because all that takes place before the OS is loaded, obviously. I haven't noticed if my SATA raid controllers do it, but all the scsi's that I have do.

I believe you are correct.

Update: Well i am on right now under FULL athlon xp 3000 FSB is at 200 or 400 quad pumped however you want to say it. SO now it looks like it is the power supply. I disco'd the dvd-rom and 1 hard drive! So lets run Prime 95 all day and see what happens!
