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....

A quality 1000w PSU easily outputs 1000w to DC side, depending on efficiency under 100% load you see much higher numbers at the wall.

For example, corsair rm1000 at 100% load - 89% efficiency @ 230Vac - 1123w (1000/0.89) at the wall. And you can easily overload them too, not saying I would do it but it is possible.

Like i thought . Thanks all for the info and help. Im cool now. Wattage of the PSU is the output ability not input.

Here's a nice explanation, from Corsair, about PSUs bronze,gold,platinum and the differences.

nice tables to show the difference in DC output and AC input.

THERE IS A GREAT DEAL OF MISINFORMATION ON THE WEB--

Thank you for the manufacturer's guide. Whether it be by trolls, or poorly informed individuals, there is a lot of junk info to discard. Overloading a PSU an cause fire, melted wires, or even an explosion. --scryptr
