Power Supply Question

[UNnamed66]

Hi, I'm going to build a mid-priced system this summer which is similar to the one that Tom's Hard built. But not sure if a Thermaltake TR2 W0070RUC ATX 430W Power Supply can handle the following components:

- LITE-ON 20X DVD¡ÀR DVD Burner With 12X DVD-RAM Write Black SATA - Seagate Barracuda 7200.10 ST3320620AS320GB 7200 RPM SATA 3.0Gb/s Hard Drive
- EVGA 320-P2-N811-AR GeForce 8800GTS 320MB GDDR3 PCI Express x16 HDCP Video Card
- Patriot eXtreme Performance 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
- Intel Core 2 Duo E6600 with ASUS P5N-E SLI LGA 775 NVIDIA nForce 650i SLI ATX Intel Motherboard

Any ideas? Also can you guys give me some comments on those components whether they're good or not? On the ram part, should I get Kingston? This is my first time building a system myself
Thx alot!

Nope, not even close. That system needs about 26a on the +12v rail, the Thermaltake you're talking about has 18a.

This is about the cheapest, quality psu you can get that has enough power for your build.

You need to find something with around 30amps on the 12volt rail.The psu you've listed only has 18amps.Spend some money and get a 600-700watt psu.I highly recommend a thermaltake toughpower 750 psu or higher.Not only will this give you the needed power,buut it will also future proof you for the next couple years.Goodluck.

FSP make the best damn PSU's. So apt403 has made a good recommendation there.

The most important thing to take into account is the number of 12v rails and the amps on the 12v rails.
The other rails are important but not as much as the 12v rail.

Alot of manufacturers outright lie about how many watts their PSU provides. FSP have built up a good reputation over the years.
The number of amps your GPU needs is always something you should watch out for, they can use a surprising amount. The 8800gts need a huge amount of amps.

Yes it will boot, thats it.

Now if you want to use your system other than for POSTing, get one of the psus in the psu reference list linked in my sig, one with AT LEAST 30A on the combined 12V rails (32A or more preferable)

 

[apt403]

Well, I wouldnt say the BEST. They're very good, but the best power supplies are the Turbo-Cool line from PCP&C and the server grade units made my Zippy and Etasis.

That FSP AX450 does NOT have enough power to run a GTS.

Try the Antec TP550 for $65 at Frys, its got 34max amps.

Another choice is the Corsair HX520 for ~$100

good luck

do you know that from personal experience?

I only ask because I'm running a no-brand 400W PSU (with +12v1=14A, +12v2=15A) with a GTS640, FX CPU, 2 hard disks, 2 optical drives, 2GB of RAM, and that all runs absolutely fine for nearly a year now

I did the calcs and PEAK my system requires 357W

PSU snobs make me laugh, I paid $30 for my PSU

 

[apt403]

Yes it does! The minimum power requirements for an 8800gts is 26a on the +12v rail, the psu I linked has 29a. Granted, I though I had linked the 500w version, not the 450w one, but still, both have enough power.

Also, I said it's the CHEAPEST, not the best. I didnt know about the $65 Trio at Fry's, that's a better deal then the FSP Group one I linked.

 

[alcattle]

true, many of the cheap PSU are still good, but when you want something you know that it is high quality. Also your PSU has a lot of Amps for a 400W, maybe they under rated it

 

[billdcat4]

Run the PSU calc and divide by 12. Thats how many amps you need. The FSP AX450 does have 29a. I have a friend who installed his the week.

The 26a number by the GtS doesnt mean much. Just have enough amps for the PSU Calc divided by 12. Add a couple for headroom.

You should see a ## between 30 and 35. Thats how many amps you need. The AX450 will not power a GTS reliably. Talk to Mpilchfamily for more info and suggestions

 

[apt403]

The PSU calculator already adds extra amps to be safe, with nothing selected it gives a reading of 38w, which is 4a. When I did it I got about 320w, 26a. Take off the 38w the calculator tacks on and you have 22a. Nvidia, the company that makes the damn card says a minimum of 26a. If a psu with that amount of power couldnt provide for the 8800gts the number would be higher.

Again, I ment to link the 500w version that has 30a, I said it's not the best option, only the cheapest, and after you mentioned the TP550 for $65 I said it was better then the FSP Group psu. I'm only saying that either the 450w or 500w power supplies WILL WORK RELIABLY. It's not the smartest thing to do, but it can be done.

Acc. to Mpilcfamily, a rig with that GPU and PSU will die within a year or two. possibly taking half of the rig with it.

 

[andybird123]

again, you know that from direct experience?

I've always used non-brand PSU's around 20% watts over what the PC needs and all the PC's I've built I've had as gaming rigs for around 2 years then sold on to mates, they're all still running (one of them is 10 years old now)

at work I've seen dozens of PSU's fail (mainly due to very dusty environments) and never take another component with them

no cant say that I have direct experience, just repeated what others have told me

Hence the "It's not the smartest thing to do".

I'm not sure why we're even fighting. He obviously isnt going to get the psu I linked/ment to link, I pretty much said he shouldnt. You proved that there are much better options available, and I've admitted that there are. When the TP550 came into the disscution the only reason to even consider the FSP Group psu, price, went out the window. It's pretty much just who's right at this point. I'll PM Mpilchfamily and email JonnyGuru, if Mpilchfamily confirms what you said, an JonnyGuru agrees I'll admit defeat.

Now, let's let this die FTM.

The Corsair 520HX that billdcat4 is a good deal, you would have ample oc'ing room, and could add an 8800gtx later on down the road if you wanted.

The Silverstone Strider 560w has the same amount of power costs the same as the 520HX does after the MIR, $105. So if you don't want to wait it might be a better choice.

The 550w NeoHE is $70 after an MIR over at newegg. It's virutally the same as the TP550, same amount of power, same manufacturer, about the same price, one of the only differences is the fact that it has modular cables.

whatever JohnnyGuru says about PSUs is truth......

Right, his site seems to be down ATM, so I can't get his email address. Hopefully it'll be up tomorrow.

AFAIK the 38W is for the motherboard, notice that a regular motherboard is already selected by default (you cant set none)
