system power supply information?

[xxndnromeoxx]

As most of you know, I've been looking into graphics cards and have seen system requirements such as

"System power supply with minimum 450W or higher"

How am I to find what my system power supply has at the moment?

This is the computer I have

HP Pavilion Media Center a1310n PC, refurbished

I am trying to find it out, but nothing has come up. Thanks!

It doesnt say on the website, but just open the side panel, and there should be a sticker, saying how mant watts the power supply is..
