Would my PSU have enough power for HD 6870?

post #1 of 11
Thread Starter 
Guys, im thinking about upgrading my 3 yr old 8600gts to a HD 6870. But i don't know if my PSU (which is also 3 years old) have enough power for the card.

If it doesn't do you guys have any suggestion for a new PSU under $80?

Definitely. 550W is more than enough, considering you only need like 600W to run 2 6870's in CF.

Might want to consider picking up a better PSU though (Corsair, OCZ, etc) sometime soon. Those 650W Corsairs are pretty popular and would be more than enough to power 2 6870's.

Would replace it with this once psu's hit the 3 year mark its time to replace them

550W is more than enough if it's a solid unit.
However, the one you own isn't too great and the fact that it is three years old tells me you should probably invest in a new one.

The Rosewill unit you have will likely be fine with the card...their RP series of the past were average compared to all their other junk models. However, I wouldn't rely on it being that it is 3 years old at this point.

These PSUs are viable replacements:

Antec Eco

Antec Earthwatt 650W

Antec High Gamer 520W

Thanks guys i think i would replace my PSU to a new one, because my SLI system somehow is not booting, but when i use only one card it works. It's probably my PSU failing.

Here i have three options, which is better?

OCZ ModXStream Pro 600W

Antec Earthwatts EA-650 Green

Silverstone Strider Essential Series 600w

Corsair is a great brand but it cost more, and i need a more budget PSU.

Looked around on Newegg a bit more and found these two.

CORSAIR Builder Series CX600 V2 600w

RAIDMAX Blackstone series 700w

I'd personally go with the Strider with the Earthwatt Green a close second.

Never ever buy Raidmax. The Corsair CX is the lowest model line for Corsair units...it's alright for a budget unit, but the Strider is a better buy.

I wonder what is wrong with a 3 year old PSU. They are designed to last longer than that.
