Sorry to bash on your deal, but it really isnt.
You are paying 15$ + s/h for a generic 250watt PSU that I bet isnt even AMD certified.
TIP: you really dont wanna buy a cheap powersupply, spend the extra 10$ and get a good one if you have a new / average system. You dont want your powersupply failing and frying up your hardwares.
If you are giving this to PIIz, I guess its no harm
