SLI/Crossfire PSU question!

Deathdread · 04-25-2008, 08:10 PM

If I have a PSU 1200watt sli-ready, will it work with ATI cards any way? The amps seem to be enough to handle any PCI-E cards with 8-pin or 6-pin connectors.

Also, why are they SLI or Crossfire certified/ready PSUs, to say that it is more efficient for those cards?

unfortunately the term "sli / crossfire ready" has become a statement which almost has no merit whatsoever

its a statement which was suppose to mean the power supply is well built and delivers plenty of clean power

now days; it really boils down to the make and model of the PSU

if you tell us the make and model of your power supply and which video cards you have >>>>> we can tell you if you can expect success with your rig

crossfire and SLI are merely competeing terms for dual "power hog" high performance video card systems...........nothing more

if you can give us the U.L. certification number which is found in the red circle of the pic I have attached

it will start with an E######

we can give you more info about yoru power supply, but judging by the cost of the unit I would have to agree you are ready to rock and roll with your rig

crap; sorry not the number I was hoping for

I will keep digging

you have purchased a server grade power supply = A+ quality

it has active power factor correction (APFC)

80% efficiency

you should be in great shape, and the purchase price was decent too, for that level of unit
