Ahh, relief. I heard that only PSU's that are certified to work in SLi mode works, and this one isn't. Thanks man, I've just ordered my new computer, and I was scared I might have bought a non-working PSU for my cards lol.

What cards? It may not be powerful enough to run the top end ones...

Two of these. Asus GeForce GTX 285 PhysX Cuda, along with this:

Kingston 6GB 2x3 2000MHz RAM Core quad i7 920 CPU VelociRaptor 150GB 10000 rpm HDD Asus P6T Deluxe V2 MOBO Asus GeForce GTX 285 PhysX Cuda x2

Will 850Ws PSU take this?

Whats with everyone running such giant power supplies for wimpy computers? Your rig would have more than enough power with a good 700-750w

How can you say that this is a wimpy rig? Thanks for your non-topic related reply again, Mr. Kowkiller.

Cheers Babeman and Sgt. D Killa.

Yes, that is a wimpy computer for a 850w PSU. As I said before, a Quality 700-750w unit will be more than enough for such a rig. People buy much larger power supplies than they need these days such as people buying a 1kw PSU for a computer that uses less than 300w of power. And considering that your rig is only going to use a max of around 500w I would say a 850w PSU is a little overboard (as long as you dont OC your processor then a 700w would be more than enough)

To be fair, most PSUs are most efficient at 50-80% load. And depending on how much you use the computer, the cost saved by the extra efficiency might actually be more than the extra cost of the bigger PSU. Besides which if you decide to get a better, more power-hungry system later on you have more options.
