Some guy just tested a ton of PSU's and has the information available on the 'net. Thought it might be an interesting read for those here who may be thinking about a new PSU.

Depends on the components of the system. You can usually get a good idea from the requirements for the video card you choose. They give you a number for the whole system. Not the card alone.

And it is always better to have more than the minimum.

The more fans, optical drives, harddrives, UV Lights and accessories you have, the more amps you need.

Any power supply can be good to you for many years, its just the ones that are branded "avoid" are more LIKELY to give you problems than the reccomended ones.

More than "good."

But, the brand is not so good.

Just hope your one of the lucky ones.

if your talking about my sig, its not that. im getting a rosewill psu (everyone says they suck but i know someone with it and they say there isnt any problems) and it is 550 watt and 35a dual 12v rail. 50 bucks. mine is really 400, but they want more people to buy it. i think it only has like 20 or 18, it sucks.

here it is

Newegg.com - Rosewill RP550-2 ATX 2.01 550W Power Supply 115/230 V CSA, CB, TUV, FCC, UL - Retail

compared to mine now (pos)

Newegg.com - LOGISYS Computer PS550ABK ATX12V 550Watts Power Supply With SATA and 20/24 Pin connectors. 100 - 240 V - Retail

Rosewills aren't that bad actually.
If you look on the guide they are for the cheaper end though..

You shouldn't and I qoute shouldn't have a problem with it.
