Radeon HD 6870 XFX power requirement

[Zero1030]

I'm still using an older system and want to upgrade to a 6870 but I'm not sure if my psu can handle it. I am using a Cougar A560.
If it's not sufficient can anyone recommend one?

the 6870 requires 2x 6 pin power connectors.

That PSU is a off brand so it might be able to supply the power... but don't know if it will last if you're pushing it to the upper end of what the thing can supply.

That PSU is kinda bad.

But if you insist on keeping it, at least get a newer graphics card than the 6870. A 7790 for example, it'll perform just as well but draw less power.

If you're going to replace it, something like an XFX 550W would be excellent.

It will work fine. I am also running mine on a 500w PSU.

But the quality of your 500W PSU is much higher than the quality of the Cougar A560.

Just based on the review you linked I wouldn't chance it. It said at higher loads the efficiency drops and they wonder how it even got a 80+ rating.

Low efficiency is something you can live with. More problematic is the fact that voltages went out of spec.
