Question about GTX 285 in SLI (stability, power requirements)

I've been looking at some new videocards recently. I've heard a lot of great things about BFG, so I decided to look at their line of GTX 200 series cards.

Since I don't think I want to mess with a dual-GPU card right now, I decided to go with the next step down, the GTX 285. BFG has a couple versions of this card, each one overclocked more and more, with the fastest one being the "OCX" version.

I was wondering if an 850w PSU would be able to power two GTX 285 OCX cards in SLI mode, and then, if that would even be stable to use.

Also, will two GTX 285 cards fit in an Asus P6T Deluxe V2 motherboard, and will they both be able to occupy the two x16 slots?

Thanks in advance.

Ok I'll tackle this one at a time.

1. Don't get the GTX 285, the 5850 outperforms it soundly and is cheaper. It can be difficult to aquire one, but possible. Just be patient. Getting anything that isn't an ATI 5000 series right now makes absolutely no sense. If you "exclusively" buy nVidia, stop now.

2. You need to post what the model number and brand of that 850w PSU are.

3. Th Asus P6T supports crossfire and SLI at x16/x16 bandwidth.

Seriously, DO NOT GET THE GTX 285, it is an extremely bad move.

The PSU I'm talking about is a CorsairHX series 850w PSU. Will that do the trick?

As to the motherboard supporting both cards at x16, I asked because the specs for the card say that it physically covers two slots. The P6T only has 3 PCI-E 2.0 slots. Would it be possible, even though the card covers two slots, to have both go on the x16 slots?

5850 in crossfire would be a MUCH better descision!! (if you can find 1, let alone a pair)

It should fit, and you're power supply is definatley enough for them (and 5850s).
