Hey I just returned from vacation. I picked up a used Dell E521 for $75.00, which I thought was a good deal. The only issues was that it didn't have an OS and a hard drive. I thought this was perfect for my niece's needs. It did come with the driver discs, which did help. I had an extra hard drive as well as XP home, which I installed this weekend.

And it's working fine now, no problems. The only problem is that the power supply unit is only 300 watts. I've read that this is one of the problems with Dell pc's, that they are under powered. But I've also heard that they are propriety and hard to find? I've searched the internet for compatible psu's and I get a link to PC Power & Cooling. I'm not to keen from buying from them, they are just way too overpriced.

Does anyone have any information about finding a compatible psu for a Dell pc. Hopefully I can get this taken care of quickly, so I can give this to my niece.

Thanks
