My PC draws 300w from the wall. Is my Antec 500w Earthwatts enough?
I just ran some tests on my PC and found that under full load (Furmark and Prime95) it never draws more than 300w from the wall (average is around 275w). I'm wondering if my Antec EA-500D power supply is enough. Here are the system specs:
I used 2 different tools to measure the wattage at the wall and both of them gave me the exact same results (275w-295w). I'm not sure if this is how it works but if the PSU is 80% efficient and it's pulling 300w from the wall, wouldn't it be putting out around 240w to the components in the PC? The PSU has two 22A 12v rails and says 500w continuous. Do you think that this is enough for my machine? Thanks very much!

the 500w is tha MAXIMUM the powers uplly can give the components. if they are only pulling 240W through the power suplly it will only draw 300W form the wall. the stated wattage is a maximum not what it is putting out at all times
