Antec NeoPower 650w for 2 4870's?

[jrb5038]

I was wondering if an Antec NeoPower 650w could manage 2 hd4870's in crossfire. Right now, I have one 4870, with a q6600 oc'ed to 3.0, and one Seagate 7200rpm 250gb HD. It runs perfect, just wondering if that psu could handle another 4870 thrown in.

Yes. If you were buying a new PSU for your system i'd recommend dropping an extra $20 or so for a quality 750w, but since you already have a quality 650w i'd stick with it. Your total system at load with 2 HD4870s will probably be under 500w.... (that's with your OC, HD and 4 or 5 fans)

Cool, thanks a lot guys.

That PSU is powerful enough for HD 4870 CF. It doesn't have the 4 PCI-E connectors you need, but some HD 4870 cards (like this one) come with adapters.
