I would go with a 650W PSU for an i7 + 680 just to give you a little wiggle room. Its always best to run PSU's at 50-60% load for peak effeciency. Personally I would go with something from Enermax's Platimax line. I have an 850W model and it has the most silent PSU fan I have ever "heard". thumb.gif

I don't think a 500W PSU can handly a 680 fine... It might overload it times at times....

Its not the wattage thats at fault here.500W is plent, but its just a bad PSU.It is unrealible, and has a large chance of failing, and a chance of frying.Go with Corsair,Seasonic,XFX, or antec.

The 680 has a typical gaming load of ~170w and may hit <~230w during stressing condition. So even if have an i7 platform, the Kingwin STR-500 will be able to power it, which is base on the high-end Superflower Golden King unit like the LZP-550 but fanless.

As long as you're not overclocking the crap out of a hex core i7, doing the same for a 680, and running a large stack of hard drives, it will be fine.

I'd strongly recommend saving some money by just getting the Kingwin Lazer Platinum 550W instead. It's the same thing, but with a fan that never turns on, except under high load.

Just FYI, this "bad psu" sure did fool a lot of reviewers:

If you're concerned about noise levels of the Lazer Platinum, check the last link.

Those 10 reviewers are all full of it! Trust me, OP. I know exactly what I'm talking about. You'll need a mega-watt PSU to power that single GPU rig.

The Stryker 500 is not only a brilliant Platinum unit (still the best fanless unit on the market), but it can also function as a Gold 600W+ unit... so the answer to your question is yes, it can power two 680s on a Sandy Bridge or Ivy Bridge platform.

Mikeaj's suggestion makes a better choice however, it's usually slightly cheaper so it offers superior value for money.

This is a much more sensible option.. As when you're fully loading it you'll be in game usually and have headphones on or music on. AFAIK Corsiars units do this too, which is why I want to swap over to one of them eventually. biggrin.gif
