how much power does 1 5770 take up?

how much power does 1 5770 take up?

108W at load, 18W at idle.

Single GPU 5770

System in IDLE = 228 Watts
System with GPU in FULL Stress = 321 Watts
Difference (GPU load) = 93 Watt

Dual GPU 5770
System in IDLE = 249 Watts (= 21W added over single GPU)
System with GPU in FULL Stress = 423Watts
Difference (GPU load) = 174 Watt

The monitoring device is reporting a maximum system wattage peak at roughly 425 Watts in CrossfireX (2-way), and for a PC with this setup, this is simply low and certainly remains within acceptable levels.

The tester did state his i7 system was power hungry with water cooling/lights so you could take off maybe 100w
