Can i crossfire?

[OtterFailure]

i have ordered a new computer and its psu is a 620w antec HCG . the graphics card is an HIS Radeon HD6950 IceQ 2Gb. i was wondering if the psu would be big enough to get another gpu and crossfire them? or will i need a new one?

No, 2 6950's will want like a 750+ watt psu,but there is no need unless you want 3+ monitors, the 6950 can be unlocked to basically a 6970, throw in a little overcllock and you just created a card worth a pretty penny more than you spent, but it hould be able to smash anything out for a little while already, ne need for more than that and you'll need a new psu and stuff anyways and need to make sure your mobo can actually perform crossfire properly, as in a x16 and x8 or 2 x8's when 2 are plugged in or something like that, not a x16 and x4.

You will probably need something near 850 watts for that high end of a video card to crossfire. But I would wait for someone else to confirm what would work best for it.

this says 750 min

that's what i always though and over the past week or 2 was corrected on that by linkin or mihir or one of the other main guys when i had said 850 and they corrected me saying 750 is fine, but still i'd recomend to try for an 800 so you have ample head room for future cards in sli/Xfire.

Thats a typo. If you read it again it says 500 watt or greater with 2 - 750 watt pci express power connectors. However, it should say 75 watt I believe.

If I am not wrong he can crossfire, but it would not be advisable to do so, since his PSU has 48A on the 12V rail while the recommended is also 48A.
And the HD6950s have a TDP of 158W.

Though I am not sure about this.

Ok guys thanks for the quick response, if i do crossfire i will get a new psu when i do anyway. But it wont be any time soon since i just ordered it, thanks!
