5970 psu reqs and question

[fornowagain]

Got a 850 watt OCZ Gamestream currently running GTX8800 in SLI/QX9650 @3.8 this would run a 5970 yes? (20amps on easch of four rails) - just wondering, as i thought, at firsrt that the 5970 was very low on power consumption, lower than a 295 for example.....

72A is plenty.

Maximum ratings are shown. The combined output of all 12V rails is 72A at ambient room temperature of 20 C

Problem isn't so much as the total power but how much for each pci-e connector.

I think I read somewhere today that it's 20a on the 8 pin and 16 amps on the 6 pin.

I know a lot of psu's which only put 18amps or less down each 12v line.....

And it wasn't so long ago everybody was laughing at people buying 600W+ psu as being overkill and not necessary........

If it's the TX then it has one single rail so you will be fine.

Them specs are for if you want to overvolt to 5870 speeds, you'll need a 750W PSU with 20A on the 8pin and 15A on the 6 pin.

As long as your PSU is rated for about 650W and isn't some cheapo thing then you'll be fine at stock speeds.

Yes it would.


I just got the HX 850 yesterday, another good power supply from corsair.
