GTX 680 on a Coolermaster extreme power plus 600

[brightside]

Hello,

I just won a in a raffle! evga geforce gtx 680

My computer is about 4 years old, though. My power supply recently went out and I replaced it with a coolermaster extreme power plus 600 w.coolermaster extreme power plus 600 w

My question is whether or not this power supply supports the "minimum of 38 amps on the +12v rail" or not. I checked the specs, but I was not able to determine whether or not it did.

Thank you for your help!

The voltage specs at your link to Coolermaster's page for the product show two +12 volt rails at 18 amps, each, for a total of 36 amps, a couple of amps short of what you're looking for.

Thank you very much. I saw that, but did not quite know how to decipher it (apparently you add the two together )

Again, thanks!

In fact, the specs show only a total of 36 amps on the two 12V rails. That 38A minimum is surely overly cautious. Most of the systems in your computer run on the 12V rail(s), so they probably assumed a worst-case of an overclocked Bulldozer CPU or something.

That said, that Cooler Master PSU isn't the greatest. Aside from the fact that it only provides 36A*12V=432 watts on the 12V rails, Cooler Master just isn't a highly-rated brand.

What does the rest of your system look like? Are you interested in upgrading some parts? Do you have a budget for parts, like a better PSU?

The rest of my build:

intel core 2 quad 2.5ghz
4 gig ram
a basic mobo, cost about 80 at the time 4 years ago.
640gig hd
9800 gtx+ (current card)

Not the most informative, I know, but I don't recall my build exactly.

I'm willing to upgrade my power supply so I can use my new beast, but I really can't afford to spend over 75 dollars.

Your post was very helpful! Thanks.

This power supply looks really good for you: XFX 550W, $50 After Rebate ($10) After Promo ($15, 'XFXPS550')

You'll be bottlenecked by your CPU, but apparently you don't have the budget for an upgrade.

A 680 in a raffle? Damn you're lucky

There's a reason that PSU is only rated for 36A or 432W of +12V despite being labelled a 600W unit. It can't supply stable voltages beyond an overall ~450W load. So essentially you have a 450W unit. You really shouldn't have bought this PSU, I'm sure there were better options available.

GTX 680 isn't all that power hungry though, you should be able to keep your gaming load below 300W, it should work just fine as long as you can avoid fully stressing the CPU and the GPU simultaneously. Here's a system with i7-965 @ 3.75GHz and a GTX 680, running at full GPU load. What's your CPU?

A 9800 GTX+ has a TDP of 141 watts and a GTX 680 comes in at 195 watts. That's only a 54W increase, so you're most likely fine with your current PSU.
