Hi guys ! Correct me if Im wrong. If i see 1100 watt from the wall on my wattmeter , so on 80+ Standard PSU its 1100*0.8=880 power load of PSU. And its good enough for PSUs working conditions (1000Watt Chieftech)?
I mean its about 85% of its full load.

Right ?

If you have a 1000W PSU how can you see 1100 at the wall? Something is wrong...

The 80+ standard is a measure of efficiency. No PSU will deliver 100% of its nominal output, 10~20% is lost in heat.

Therefore, a 1000W PSU will only deliver ~800W within a limited range of loads, and not at full load. Got it?

A 1000W PSU will never "suck" 1100w from the wall....



That is not correct.

"Load Regulation And Efficiency Measurements
The first set of tests reveals the stability of the voltage rails and the PSU's efficiency. The applied load equals (approximately) 10 to 110 percent of the maximum load the supply can handle, in increments of 10 percentage points...... 1500W PSU Output - 1549.07W, efficiecny -89.04%, PSU input 1739.84W ......"
