TDP wattage is 110.
To say a "550w" ps will do the job is not even possible being the actuall quality out put of the unit is what matters, being many PS maker over rate the "Wattage."
Having two power in vid cards, the minimum amperage you should have on the 12v+ rails is 36. Make sure the PS is SLI rated too!

Give us the specifications of the exact name fot he PSU.

Sure a good quality 550W psu would do fine, but if it is generic it may not hold up so well.

well originally i was looking at this http://www.newegg.com/Product/Produc...82E16817170017 since i dont have much money
I looked around at more expensive psu's and found this http://www.newegg.com/Product/Produc...82E16817159054 which looks to be much worse but its a brand name check the 12v rails on each and tell me what you think
post #8 of 9
The Logisys with a single 25a 12+v rail won't likely run two 7900s.

Probably the best for the buck...
http://www.newegg.com/Product/Produc...82E16817189014

BTW, the PS is like the most overlooked part of a dependable and OCable PC!

Things to look for in a good PS...
Active PFC for stable power.
The 12+v rails
Efficency 80% is very good ... mid low 70 not to good.
Alwasy check that the needed connections are there.... 20/24 pin, 4 pin 12v (or in some MBs 8 pin 12v.) SLI support if needed, etc...

That XCilo in perticular uses a whopping 140mm fan, great for flow and usually not noisey like the ones that have an 80mm rear fan and 92mm top fan.
