Crossfire PSU and Mobo

[chiknbane]

I'm building a new pc in a couple of days and getting a HD 5830 with the intent of adding a second later.

Will this PSU be good enough for crossfire

if i get a couple of http://www.ebuyer.com/product/124029 because it needs 2 6-pin each. Will there be enough connectors and do you need to put 2 4-pins or just one in the adapter?

What would be a good/cheap AM3 mobo that will support crossfire? Do you need 2 x16 bandwidth slots? Whats the performance difference if you use a x8 or x4 slot?

Will be with:
Phenom II x4 965
4Gb 1333MHz DDR3
Antec 200 case with extra 120mm fan
2x500Gb HDDs in Raid 0

http://www.ebuyer.com/product/135514 get that instead

Yea you need 2 4-pins to make the 6-pin, you will have plenty of spare ones for this.

This motherboard would work well, http://www.ebuyer.com/product/196392 though its not true crossfire with only 16x and 8x, though the performance decrease is pretty minor. Stepping up to this http://www.ebuyer.com/product/218919 would give you the full crossfire, as well as some more updated features. I would stick with that 790 board.

I would drop down to the Phenom II X4 955, because the 965 is only factory overclocked, by one multiplier, this is something you can do yourself with one click, for $40 less...

1. You would want at least 8/8 on PCIex16 gen 2.0 for CF
2. Why not try to hit a HD 5850 and stick to single GPU solutions?
