I don't know how many of you have read this article but it was very interesting. He powered a high end computer on 380 watts.

Makes you reconsider the 700 watts + Power supplies.
post #2 of 5
The issue with running a 380W system off even a 400W power supply is that most power supplies (irrespective of what they are used for, in any electrical system) typically are most efficient at around 50-60% from my experiences. Can you run a 380W system off a 380W power supply? Yes, but you are drawing probably 440W from the wall. Now, if you had a 750W PSU, you would probably only draw 400W from the wall. These are arbitrary numbers but they illustrate the efficiency point well.

True, but I am sure you can get a very efficient 450 watt power supply for the same or less than a good 750 watt power supply, which would end up being much more efficient (And hopefully cost less)
