550w PSU, enough?

Would a 550w PSU support my new system...

AMD X2 3800+ OC's to 2.7GHz
1024 MB RAM
250GB DiamondMax HD
XFX 7900GT 256MB

More about 550w enough
  1. 550 is overkill.

    450 is more than adequate.

    550 W for the AMD X 3800 + is a bare mnimum I would recommend.

    PSU is the most important componnent of any PC to assure proper operation and system stability.

    I have non SLI system 600 W and I wish I would have just another 50 W for future expansions. However as a hair line of CPU goes down the power consumption should go a little down.


    Buy thew best PSU you can afford and never look back at the ice.

    Don't ever allow yourself to be caught with pants down!

    I am using EG701AX-VE SFMA and I wouldn't trade for less.

    ELT620AWT

    Good PSU mean super quiet PC!

    For the same reason I do refuse to consider other brands than Enermax.

    ehhhhh

    In your case you do not need PSU you may use the sheep manure to heat your shack!

    It is better do not give advices rather than to mislead others.

    There are other considerations that just maximum load PSU might handle.

    I wouldn't ever buy anything less than 550 W, it is always better to have cusion than to fight frustrating freezes.

    The few bucks one pays in the diference for good branded 600 W is not worth even any discussion about lesser PSU qualiy!

    You get what you paid for and no more!

    Whaaa?? No. 350W would be bare minumum, ONLY if the power supply is a high quality, top brand. 450W would be more than enough, providing the PSU is very good. More W doesn't mean anything if the PSU is from a dollar store.

    350 W ? say what?

    The almost perfect PS will have about:
    +3.3V@30A, +5V@35A & +12V@33A


    ONLY if you overdose on PROZAC but than you do not need any more any PC! as you will be either suicidal either locked up!

  6. I don't care what anyone here says, I've seen good 350's run everything but SLI'd systems. If they are solid I don't give a shit what the ratings are, they will run fine. Everyone seems to overrate the output of ps's, the quality is what counts.

    What the hell are you smoking?

    A stock X2 3800+ consumes 65w of power.
    A stock X2 4800+ consumes 96w of power.
    A X2 3800+ OC'ed to 2.7GHz will probably consume 115w of power.

    CPU power consumption chart.

    An overclocked 7900GT will consume around 57w of power. This chart shows theEVGA e-GeForce 7900 GT CO SuperClocked consuming 57w of power.

    Add in the following:

    Motherboard.........................20w
    2 sticks of RAM.....................10w
    Sound Card..........................10w
    2 120mm case fans..............12w
    1 DVD Drive........................16w
    1 Raptor 74GB HDD..............39w
    1 300GB HDD (or smaller).....16w

    That adds up to a max 295w of total estimated power. Maybe 285w because I don't think RAM draws power from the 12v rail. That is assuming every single component is being stressed at 100% all at the same time. That is unlikely.

    Any good quality PSU that can deliver at least 300w on the 12v rails can power this system. For example:

    Seasonic S12 430 430w PSU. It can deliver a total of 29 amps on the 12v rails for a total of 348w of power.



    Antec TruePower II-430 430w PSU. It can deliver a max of 17 amps on each 12v rail, but only a total of 31 amps when both rails are stressed. That a total of 372w on the 12v rails.



    Enermax Noisetaker EG495P-VE SFMA 485w PSU. It states 18 amps for each 12v rail, or a total of 36 amps. But 18 amps could be the max for each 12v rail, but when both are stressed, it may only produce 32 amp or 384w of power. That's just a guess since it does not explicitly state that the 12v rails can provide a total of 384w on the sticker.



    Buying a premium or good quality PSU is always a good idea. But it's not necessary to go overboard on total power.

    Also, the load on the PSU affects the efficiency of the PSU. The lower the load the less efficient the PSU will be. A Seasonic S12 PSU is typically at the higher end of it's efficieny when the PSU is stressed between 60% - 90% of it's rated power. That means the more power it draws the less electricity from the A/C outlet is wasted.

    I have also, and they made a great Freedom Fries (previously French Fries).

    It's only money, but no headaches.

    I wouldn't recommend to buy PSU with each upgrade.

    Also if noise is of your concern don't ever buy BRANDs like "El Cheap".

    Look at general picture of possibilities CROSSFIRE / SLI / Single

    8 x hard disks 3 DVD RW 6 USB / 2 x 1934 , 2 PCI slots.

    Wireless / 24 / 7 / 365 operation.

    Do not learn on your errors learn on others !

    Notice also he wants to OC to 2.7 Ghz, that is a demand for steady juice draw.

    check extreme overclocking

    You get an idea.

    Keep in mind X2 means multitasking so you need good Power Factor.

    I want to have at least 30% in reserve for expansions.

    Also depending on your climate you might want better PSU.

    In arctic climate you can cut 10% in tropics with no A/C ad 15% power reserve.

  10. First off, don't quote long posts like that, it's annoying.

    Second, settle down, you are wrong, deal with it.

    Many, many real life experiences have led me to the same conclusion, a high quality 300-400 watt supply will EASILY handle any non SLI load, search for my name and you will see a post that has "How much crap can you run off a 300 watt ps" or something like that. Plenty of people have done it and will continue to do so. If you want to overpay for unnecessary equipment fine, but don't give bad info to other users.

    A buddy of mine just built a dual opty with 4 gig ram, 4 wd raptors and ati x1900xt and he's running it off a fortran 400watt ps that hardly gets warm.

    And his rig noise level ~ 87 dB?

    My PC is whisper quiet! HD make more noise than CPU / PSU!

    Friend of mine built a rig with P4 3.2 Mhz with 450 W Fortron PSU, I thought that some one parked a truck in front of his bed!

    The combined noise level between CPU Fan (@ 5200 RPM @ 64 degree) and Fortron 450 W PSU reminds me an airpport noise.

  12. Uh, it's not that noisy actually, you can hear the dvd spin up over the noise of the fans for christ sake. I'd say uper 40db range at most. Good case and 120mm fans keeps it quite. Cheaper than a much larger ps too.

    So what?

    Your argument is MOOT.

    40 dB?

    I guess you have no idea what 40 dB is!

    40 dB is a level below the background noise in a very silent

    Wait for major freeze, you will learn that ione PC freezes when you ned it the most will cost you more than the cost diference on any PSU!

    My recommendation BUY only the best and do not rant that you could get cheaper.

    The point is you don't know what you are talking about.

    The above is not my rig, but a hypetheticial one. It demonstrates that a PSU of less 550w is more than capable of running an X2 3800+ OC'ed to 2.7GHz, with an overclocked 7900GT. Those are the two most power hungry components that the original poster listed in his rig. See the first post.

    The USB ports do not run off of the 12v rails. They run off of the 5v rail, so it is not necessary to take thier power draw into consideration.

    The average hard drive power consumption of 16w may be a little low, but your 40w each is way, way to high. Refer to the following article:

    Hard Drive Power Consumption and Heat Dissipation.

    RAM runs off of the 3.3v rail, so it's power consumption can be excluded from the 12v rail power calculation.

    I have mixed feelings about adjustable voltages. First off, a solid power supply shouldn't need to have it's voltages adjusted. There's the argument that the adjustment can "help overclocking RAM," but the adjustments an only be made so high and one has to keep in mind that there's more than RAM running off of the 3.3V rail.


    Unfortunately, there are no resources for how much a typical motherboard will consume so I won't argue the point.

    Same thing can be said for a typical sound card. It obviously draws no where near the power of a GPU. But since a budget video has more transistors than a sound card, a sound card should draw less power. As can be seen in this chart from Xbitlabs, the weakest GPU uses 24w. I would think that a sound card with less transistors will consume a lot less than that.

    I agree that all PC rolling off the assembly line has poor PSU for upgrading purposes, but they do provide enough power to run the components that they are built with. Are they good quality PSU? Well, that's a different story.
  19. 550W should be more than enough. I'm sorry that this little argument has come between you and a straight answer. I have a rig very similar to the one you are planning on building with some differences.

    I am running an X2 3800+ (not OC'd), 7800GT (470/1100), 2GB RAM, and 4 7200RPM drives. I'm using a 500W Antec SP2.0 power supply. Most of this is in my sig. I also run it 24/7 at full load (on the CPU).

    I admit my rig is louder than I'd like it to be, but that's because the NB fan on my crappy ECS mobo is loud, and I have 4 case fans, 3 of which are using fan filters. The filters are on the intakes since I have uber dust where I am currently living (the filters saturate in about 3-4 days) so I have to run the fans relatively fast to keep airflow decent. That said, before I moved here I only used 3 fans (all at lower speeds) and no filters. My (stock) CPU fan isn't really audible, and neither is my PSU's fan or the fan on my 7800GT... and my temps are reasonably low.

    OK, I've said my piece for now... pcrig flame on.

Besides, no one abolished the problem of high start-up power consumption – for example, the plain Barracuda 7200.8 may draw up to 2.5A from the +12 V line at start-up.

In this case you should play safe and take a PSU at least by 100-150 W more powerful than processor+video+motherboard require. Food for thought.

    Actually, I did read part of the article. As for the part of the article you quoted here is the important fact:

    Quote:

    Barracuda 7200.8 may draw up to 2.5A from the +12 V line at start-up.


    That’s for a total of 30w off of the 12v rail. If you recall my power calculations are for the 12v rail because it is the one that is being stressed the most. There is an additional 3w of power drawn from the 5v rail.

    Also, I stated in my previous post that the 16w estimate I used was actually on the low end. Your estimate of 40w is a bit high. Based off of the power charts the real answer is in the middle, with faster and higher capacity hard drive consuming more power of course.

    So how is that fact that RAM is drawing power off of the 3.3v rail crap? If it does not draw from the 3.3v rail then let me know.

    Regarding both the motherboard and sound card: Since I can’t find a power measurement that is within the ballpark of my 20w and 10w estimate, respectively, how it is that my estimates are crap? Yet you state that the motherboard consumes at least 40w, and that the sound card uses 25w? Isn’t that crap if you cannot back it up without some type of documentation?

    If you have links to that can provide that type of information, then I would appreciate if you can post them.

    ===================

    Lastly, you say that I am ranting, but have you checked the meaning of the word "RANT" recently?

    The meaning of "rant' from Webster's Dictionary:

    1 : to talk in a noisy, excited, or declamatory manner

    2 : to scold vehemently

    transitive senses : to utter in a bombastic declamatory fashion
  23. Based on this guys grammer, I would suspect a dictionary definition is beyond his comprehension. This thread should stop now, we've determined a 550 is enough; enough said.
  24. Gee I am almost afraid to comment.

    HD's use an average of 16 Watts...after they spin up to speed. Untill then they tend to use three times the power.
    Just keep that in mind when you do the math to see if the PSU will be big enough.
    I fill my Coolermaster Stackers with drives and all my Optrons have about a 1Ghz OC so I use real PSU's.

    Get a PC Power & Cooling 510 as that is the rated pwr output @ 50C not the 22-25C all other supplys are rated at.
  25. Ok, let's all forget that we've seen rigs run on 350-400 watt psu's as long as it's not sli, and just admit he's right. I mean, the psu will most likely still be working when the rest of the system is outdated and needs replaced, and when it's time to upgrade, come on, we know we're all gonna be running a 4 socket motherboard. We're going to have 3 AMD processors and a physics processor all comunicating to eachother over the ht. We're going to be running 8 video cards, 16 hard drives, a wireless network adapter, bluetooth adapter, fingerprint reader, voice recognition security, 8 case fans, 10 uv lights, and the motherboard is going to have 32 usb ports. The usb will charge your digital camera, your cell phone, and your 175 gig ipod. In fact by this time we'll be able to power our toasters, microwaves, and tv's all with the usb ports on our computers. :idea: I recomend NOTHING lower than 20,000 watts if your building a new computer, or upgrading the psu.

    Meanwhile, I'll stick with the 400 watt I've currently got running a non-sli system which IS a no name psu that came with the case and both together cost me $45.00 and is still going strong after 2 years. I will admit I got lucky though. For the most part, you SHOULD go with quality psu's.
  26. With 550W U can kill a horse :lol:, and a cowboy .
    And when cowboy scream at 40db you will never hear again.
  27. Here here!!

    I'll consider upgrading my psu when I get my USB kettle!

    480Watt is enough for that.

    As long as you have useful information to share with people, why not just post it?

    If you are concerned about receiving an outburst from PCRIG, don't be. All he can do is give verbal abuse. He doesn't really provide reasons for his position, and also doesn't provide constructive criticism. Just be ready defend your position, he'll get flustered maybe make one more useless remark and then disappear. But I can understand if you don't want to deal with unreasonable posters. Hell the CPU is filled with blind uncompromising fanatics.

    550 W for the AMD X 3800 + is a bare mnimum I would recommend.

    PSU is the most important componnent of any PC to assure proper operation and system stability.

    I have non SLI system 600 W and I wish I would have just another 50 W for future expansions. However as a hair line of CPU goes down the power consumption should go a little down.


    Buy thew best PSU you can afford and never look back at the ice.

    Don't ever allow yourself to be caught with pants down!

    I am using EG701AX-VE SFMA and I wouldn't trade for less.

    ELT620AWT

    Good PSU mean super quiet PC!

    For the same reason I do refuse to consider other brands than Enermax.

    I think this guy is in the PSU sales business... no other explanation is possible.
  32. The bold text indicates knowledge. The insults are just perks.
  33. I'm running

    x2 3800 oc 2.46
    1024MB RAM
    120GB SATA
    7800gt oc 470/1.15
    tv tuner

    off a 500 watt psu

    Also if you can oc the x2 3800 to 2.7Ghz you'll be very lucky. I reached the limit at 2.49 but took it down for more stability the oc's for the x2 3800 are about 2.3-2.5

    Sorry.

    I thought my replies to PCrig were more or less even toned.

    The above was simply copied from Webster's online dictionary.

    Since you've asked I can assure you that one less than you!


    That explains it...pcrig, you're all bricked up.

    A 550w PSU is more than enough for this, and leaves plenty of expansion room. Buy a good one (maybe better than mine, though they've given no trouble), but a 450 would be big enough.
  36. lol dude u must be just bull******* a good 450W psu is good for that build that that person has 600W is an overkill and a 550W is as well
    what ferytails did u read ???????!?!?!?!?! lol even on max load that system wont even reach mutch more than 420 maby. and btw do u really think that anyone cares that u bought a 600W psu ????? good for u m8 but for that system a good 450W or at max 500W will be very nice and sufficient.

    no offence ...but what are u smoking? seriously?
  37. Meh. This isn't that bad comparitively. In one thread a couple months ago, a n00b was hoping to build a new gaming machine. No SLi or Crossfire though. Anyways, he was asking about PSU Wattage, and this one guy said that ever since his 600 W PSU had failed he had always gone with 1 KW PSU's. He was completely serious also. He honestly was recommending a 1 KW PSU, and nothing we would say would make him listen to reason. In the end the n00b listened to us, and not to the idiot who got the 1 KW and the 1 KW guy skulked away.

    So, yeah, 550 is MORE than enough.

    I'm going to have all the things in my siggy, and Zalman 9500 running on a Antec TruePower II 450W. And I can tell you with almost complete honesty, that it will work perfectly. Oh, also, I'm hoping to get up to 2.6 on that Opty.

  38. I have a Coolmax CR-450B 450W power supply in my current PC. Is tha good enough for the following upgrades?

    S939 Athlon x2 3800+ (OCed)
    GeForce 7600GT (OCed)

    if it makes any diff, I also have the following

    Asus A8V Deluxe
    512MB of ram
    sound card
    60GB hard drive
    80GB hard drive
    DVD burner
    19" Acer LCD
    floppy drive
  39. I would highly recommend using a PSU calculator. Their are a lot of good ones out there, and you can include all kinds of stuff, including OCing. Here's a good one that I use. Also, remember, their is barely any possibility of all of your stuff being used at max load at the same time. It just doesn't happen.

    Okay, after throwing in some numbers the calculator spat out 280w.

    But at the top of the page it has the following

    Quote:

    The total Watts is important but the Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage. Because of the increased power consumption of the new high-power video cards the recommended minimum for +12V is 26A, for SLI 35A.


    I'm not sure what that means. :oops: Can you help with that?

    Thanx
    :D
  41. just one thing
    you live in Europe? (to the original poster)

    if you do you can buy this one:
    http://www.hipergroup.com/English/products/hpu-4k580.html

    it's cheap, has good reviews on the net, has 580 amps (630 max), and is nice to see 8)

    just a suggestion, say if i'm wrong

    It'll be fine, so long as the PSU is from a reputable brand, also, check the 12v line. It should have at least 20 amps to be able to run that video card.
  43. much more then enough and u hav room for upgrades
  44. Hmm, I wonder why that guy hasn't replied yet. I'm just waiting for his most recent bull shit. :lol:

    No, really, I want to see what he comes up with this time.
