If you notice, ATi says the FSP FX600-GLN and FX700-GLN are both certified for crossfire with the X1900 series. Of course, don't forget that FSP under rates their units, so it's probably more like 18A per rail on the FX series. If you really want power, there's always the PC Power & Cooling 850W. Expensive, but it will power nearly anything you throw at it.

No. you can't add up. FSP has a total output of 680W on 3.3V, 5V, and all 4 12V rails combined. If absolutely no power is drawn from 3.3V and 5V., then 680/12 = 56.67 Amps is available for the 12V rail. If the load on 3.3V and 5V is 50% for each, then (680-3.3*18+5*15)/12 = 45.5A is available for the 12V rails.

For the Xclio, I am unable to find the total output on the 3.3V, 5V, 12V rails, or the multiple 12V rails. However it cannot be more than 750/12 = 62.5 Amps available for the 12V rail. If the load on 3.3V and 5V is 50% for each, then (750-3.3*15+5*14)/12 = 52.5A

EDIT: yes, I agree.. the FSP's are great. Of the two, I'd take the 700W for the X1900XTX's. If you go for PC P&C, then take the kilowatter; it's only a bit more money than the 850W version.

Final post for now..gotta go.. otherwise, gf kill me !

OK, but isn't 40+ enough?

Also,
FSP Group FX700:
680W - 155W = 525W
525W / 15A = 35A for 12V rails
But why would ATI certify it if it weren't enough?

Modular not the best idea for high end. You loose efficiency through the connectors.
jus wondering how can modular not be the best idea when all you are doing is jus connecting and disconneting wires, if the wire is not connected u should not have any power loss, it would jus be the same if the wire was constantly connected. correct me if i'm wrong though.

Any additional connector in a wire results in a bit more resistance. That's why

really last post.. I hope I did not confuse you guys too much.

Yeah, it should be fine. Wattage calculators say the watts will be good, and there's enough amps there to power nearly any rig.
post #17 of 100
wouldnt that mean that having all the wires connected would result in more resistance than jus having a few connected?

For XClio:
750W - 180W - 24.6W = 545.4W
545.4W / 12V = 45.45A

I highly doubt there are any single 12V rail PSUs that have an amperage level that high.

For Seasonic:
600W - 180W - 19.6W = 400.4W
400.4W / 12V = 33.37A

For Enermax Liberty:
620W - 170W - 22.2W = 427.8W
427.8W / 12V = 35.65A

XClio is still in the lead by these calculations then, with Enermax second, FSP Group third, and Seasonic last. For those of you who say by a PC & C 850W or 1000W PSU, I am not spending that much money on a PSU, so unless it is under $300...

Another question:
Should I worry about the PSU being ATX12V and EPS12V compatible, or should I just stick with ATX12V since I'm going intel and not AMD?
