will a good 650w suffice for this Sandy bridge system ?

post #1 of 9
Thread Starter 
Hi fellow OCers.....
My friends is going to upgrade his old pc very soon, and the new setup would be as following . Also he is going to be overclocking , so I will add the relative overclock as well.
Asus p8p67-B3
i7 2600K @ 5GHZ
2 x 2GB XPG gaming V2 2400mhz
Gainward 570GTX Phantom ( Don't know how much he is going to OC this, but this card is one hell of a beast, so I assume a high oc is likely).
Noctua NH-D14

As for the PSU he is wondering if a good 650w PSU will be enough ??

A good 450w would be enough. So yes.

Yes. Sig rig uses 715 watts under full load. And that's with two additional fermi's.

650W will be more than plenty. For reference, a 990X @ 4GHZ and 2 way SLI GTX580 run great with a 750W PSU.

I have a 750w PSU, even if I add a third 5850 my 750w would laugh.

You'll be fine with something even less.
post #8 of 9
I agree that it'll be enough for sure. By the way, tell your buddy to be careful oc'ing his gtx 570, they tend to umm... Blow up, the vrms do.

Thank you all for the replies.

REP to all.

oh, and bout 570 blowing, this card is gonna be fine as the VRM circuity is upgraded to 8+1 from 5+1 and the cooler is a custom huge 2/5 slot heatsink + triple 8cm fan.
