5870 CROSSFIRE CONSUMPTION

[crincler]

Hi im looking to crossfire 2 HD 5870's but was wondering the power supply it would need. I currently use a 600w coolermaster, now is it enough and if not what would be?

My Rig:
Intel Core i3 530
ECS p55h-a motherboard
Kingston Hyper X DDR3 1800mhz 4GB
600W coolermaster

Probably not enough power (Coolermaster's PSUs are low). You might have a bottleneck with the i3-530 too.

so what size psu would you suggest?

I would be at least shooting for a 800W but what does your 600 have on the 12V rail(s)?

at least 750 or 800W!! Corsair, Thermaltake, ANtec, Seasonic, OCZ...

His board and Proc does not take up that much wattage but I would like to see what the 12V could handle. In the end it is looking as if he will need to upgrade.

What? please explaine the "but what does your 600 have on the 12V rail(s)? " sorry just dont knw wat you mean?

Either written on your power supply it will state how much amperage your +-12VDC will support.

Or you can look up your specific model number and find it using google.

You are going to want at least 55-60amps which I am sure you are short of but just want to verify before you lay down some coin on a new PSU.

Seasonic
Antec (Not Basiq)
Corsair
OCZ (ModXStream)
Enermax
PC Power & Cooling
XFX
Silverstone (Very few)
Rosewill (Some of their units are okay, manufactured by Newegg)

That is a nice rough-list of what you're to look for.

After this review it doesn't look good. I would look at the XFX850 and I have a pair of 5870's in the deals section for sale for 300.00
