DOUBT WITH PSU EFFICIENCY

[Greg_titan]

What is the actual power I'll get from a Corsair RM 750W 80 Plus Gold?

• 80% efficiency-->

1. 750*0.8=600W
2. ​750/0.8=937.5W

750W is the output rating. 80 PLUS Gold is approaching ~90% efficient depending on the load.

It means it can deliver 750W to your components, at max load it will draw more than 750W from the wall because it doesn't convert AC with 100% efficiency. So you'd get 750W of power, consuming about ~833W from the wall with 90% efficiency (750/0.9)
