Enough Juice ?

post #1 of 5
Thread Starter 
'Morning, I currently own a 550w but plan on getting another 6870.

I have 4 HDDs, LEDs, the whole nine yards.

Had my eye on the 660w http://www.scan.co.uk/products/660w-...ssfire-eps-12v love its look.

Pretty sure that would be more than enough. Just looking for confirmation I guess

Or suggestions for a different PSU ?

I think that a 550 Seasonic would be fine, maybe even the OCZ would be ok Xfire, the 6870 isnt really that hungry for power, 660Watts is WELL safe.

Cheers, yeah the 550w might be ok but it will really be pushed to its limits with overclocking. Think i'll pounce on the seasonic.

That Seasonic will be more than enough, you'd be able to crossfire 2 6870s easily as well.

It is enough, But it will surely consume ~450w under load, I say limited overclocking, But it will be fine
