Is this a good psu? - Page 2

post #11 of 23
im thinking a 650 should be more than enough, Im running the same psu as hobbiecat recommended and all is well.

Even a really good 550w psu will be able to do it.

I'd say go with AT LEAST a 750w for crossfire 6950s. If you are OCing the CPU and GPU as well it will bring wattage up VERY high more than some people think. You may possibly run two on a 650 but it will be pushing it's max and will not be efficient by any means since power supplies are MOST efficient at 50% load and the least efficient a low % and high to max %. Some power supplies will burn up if they pushing their max often especially cheap ones.

You should look at some Corsair, OCZ, Kingwin, XFX, Silverstone, Antec, Coolermaster

Antec TP-650
XFX 650W (either the XXX or Core edition)
SeaSonic X650

No need for 750W, let alone more than that.

EDIT: 750w for headroom or 650w which is more than enough.

This is a approved psu for the 69XX series cards from AMD.

For CF you need four 6 pin pci cables, this psu has 4.

The corsair TX650 V2 is an excellent psu, same goes for the antec tp-650, seasonic x650 or the XFX 650w (XXX or core edition)

From those get which ever is cheaper.

While I agree that the modular PSU's are sweet, my concern is clean consistent power. I would imagine that 1 pair of pci are hard wired to the psu, the others are probably modular.

I looked at your case on newegg and it's max length for vid cards is 10.5. The 6950 is 11".

If your going to upgrade your case you need to look for something with better cable management.

If your going to mod the NZXT, maybe modular is your best option.

The XFX as mentioned before is probably you're best bet for a decent priced modular that is still a quality unit.

I'm getting a whole new case, the haf 912..even if it doesn't fit there i'm willing to take out the hdd cage. Also, i'd like at least 700w, but i'm tryin to find a quality 700w under or priced at $100.

how's this?
