How many watts will this PSU give me on 110v.?
Based on how they describe it, the PSU will provide 1500W. Just remember on 110V, you will be pulling twice the amps compared to running on 220V
Each PSU is rated at 92% efficiency... soooo when you do the math:
750 * 2 = 1500 - 8% = 1380
I might be wrong but I think the efficiency calculation goes the other way.
1500/.92=1630
