.... buying anything lower than a 650 watter however won't save you any significant amount of money if you buying anything decent. Plus remember that PSU's hit their peak efficiency about at 50% loading.
Buying by brand it is sold under is meaningless ..... buying by who actually built it a little less so. Most vendors sell good, decent and crappy PSU's .... most manufacturers build good, decent and crappy PSU's. here's an oldpost Imade on the subject quite a while back:
Also, advice about brands should be taken with a few pounds of salt . Which of the following do you think is true ?
Antec makes crappy PSU's
Antec makes good PSU's
Antec makes very good PSU's
Antec makes great PSU's
The answer .... all of the above. Manufacturer's are in business to make money ... the more they sell the more they make. Targeting a single market segment limits the number of customers you can sell to, limiting the amount of sales. So most vendors sell to multiple market segments:
Its just the 2011: Brands Vs. Manufacturers list and it's incomplete at that. There are no links to test reviews of anything they've listed. There's no indication of which OEM made which model in a series.
If you do not have any multiple video card plans in the future, then surely a good 500W PSU will suffice.. And by good I mean anything from Corsair (not one from the CX series though), Seasonic or Antec..
Many thanks to everyone for their opinions. I decided to go with the High Current Gamer 520W power supply from Antec. It has everything i need, while not breaking the bank. Also, its based on the Seasonic S12IIB design, so thats gotta be good right? Once again, thanks to everyone
