Most powerful card with CoolerMaster M620 PSU?

[jmp_78]

I have a CoolerMaster M620 PSU. It's rated at 700w but guarantees a continuous 620w. It's modular and comes with 2 x 6pin and 1 x 8pin PCIe connectors.

What's the most powerful graphics card I could run safely with this PSU?

It's already powering an i5 750 @ 3.8GHz and 4 x HDDs.

Thanks!

Any card to be honest, you would only struggle if you were using crossfire/sli (or possibly something like the ati 6990 which is two gpus stuck together).

Would I manage a GTX 580? Just not sure about PCIe connectors...

480 SOC Would be better bang for the money, But the PSU Would be able to handle a 580, What motherboard do you have?

Go the GTX 480 SOC. It uses 6 pin + 8 pin afaik

Motherboard is an Asus P7P55D.

I would have already bought this... if there hadn't been so much trouble with stability issues and RMA's. Each to their own, but from my point of view, I'm not prepared to risk the mucking about. Seem to be no end of ppl in those forums with 700/800w PSUs having problems (although maybe not PSU related).

the SOC problem is not PSU related.

the SOC problem is not PSU related.

Fair enough, I presumed 620w continuous was fine. 'Tis just the other issues that puts me off!

So... cards that need 2 x 8pin PCIe connectors (GTX 580?). My PSU has 1 x of these.
Would using a (probably supplied) 8pin adaptor be safe enough? I don't wanna shell out for a new PSU as well, so just wanna get the best I can with the power I have.

it may be in some cases
