How do I figure out what power supply my computer has?

[Bill in NH]

How can I figure out how powerful my power supply is? I have reviewed all of my computers spec. sheets and I can find nothing listed as 'power supply'. Could I look this up via the computer's control panel? Is power supply listed another another name?
Tks,Bill

look it up on the manufacturer's website. it's usually listed in the specs. if not open it up and look on the psu. there may be a label on it.

Alternately, look on some of the websites that sell power supplies. Often you only need to know the computer model and they'll tell you what's compatible - along with the specs.

But avoid the following like the plague, a rip-off outfit with lots of aliases, including...

There should be a label on the PS. That's about the only way to tell if you don't have a part number from the PC manufacturer.



The maximum power output doesn't tell you the power output for the individual rails, which may be more important, but that info should be listed also.

A Geforce 6xxx/7xxx card will be looking mostly for extra +12VDC and require a hard disk like power connection. Some lower performance cards do not need this power connection.


Cards with this kind of power connection need an ATX v2.0 power supply which you don't have.
