with ease

It would be more than enough.

ive bin out thwe loop for a while, why is it everyone is buying coolmasters all of a sudden? i see seasonic no longer do my 600w psu either, tahst a shame. Is a gooden.

seems to be good for wire managment... also relatively cheap

sketch145 · 19 Mar 2009 at 18:55

looks good, especially at that price.

If you've got a big case, the PCI-E power cables are rather short. It also has the propensity to whine under load, so I sent mine back.

No way.

2 4870x2's are going to need 600W, then an overvolted quad (q9550 or i7 etc) worthy of powering 4 top gpu's is going to need 150W, before mobo requirements.

hmm intersting...

I agree, a pair of x2 4870's with the rest of the system would be far too much for this unit.

It's only rated at 624W cont @ 40C wheras a Corsair HX620W is rated at 600W @ 50C.

With two beefy cards and the rest of the system components temperatures will rise.

Quad 4870's consume 700W at load

If you really think you'll go quad, look at 1KW supplies since an ideal PSU should only be loaded at 60-70%

Thats assuming future games/drivers dont get quad cpu and gpu scaling down to a pat and push that hardware higher.

700W for a full system with 4ghz I7 and 4x4870 gpu's sounds tad optimistic to me.

ignore.

Just got a wattage meter thing for my system and my 4Ghz i7 and single 4870x2 have hit nearly 600 watts while under load. I'm about to add another one too so will let you know what it does then.

That is not going to be enough for a pair of X2s. The rig in my siggy with only a single 4870 draws 274w at the wall. You are going to need a psu approaching 1000w for a rig like that.
