How do I check what kind of power supply I have in my computer?

Asked by erik (60

I’m thinking of getting a new video card that has a requirement for a 450w power supply. But I can’t seem to find out what power supply I currently have. I don’t see it in my hardware profile, and even when I open the case the power supply doesn’t have any distinguishing marks on it that I can see (at least, without dismantling the whole rig.) Any ideas on how I can find out this information?

Try using a volt meter, you could also take it to a shop they should tell you for free

it should have a label – sometimes visible without opening the case. Sometimes you have to open your case for that. Please do not open the power supply itself, because it is dangerous, even when the computer is unplugged.

only way I can tell on mine is if I open the case. if you still can’t see it that way, if there are bo marks at all its probably generic. best way would be voltmeter like the first response in this post
