Power supply for Dell Optiplex GX520

[steamroller16]

I am looking for a replacement for the power supply in an dell optiplex GX520 small form factor (I think). The power supply has the following model number written on it: H220P-01

Is this power supply a standard type (ATX, BTX, etc...) or do I have to buy an exact replacement from dell?

Thanks for the quick reply.

Most of the ones available are used or seller refurbished. Is it ok to buy seller refurbished? Do these usually work? I don't think they have any warranty.

You're probably right. I should probably tell my friend (computer owner) to buy a new computer. The replacement power supplies are really expensive and the computer is getting really old.
