Need to upgrade power supply for a Dell Dimension XPS R400

I am looking for a larger power supply, preferably 350 or 400 watts to upgrade my current 200 watt power supply.

The computer is a Dell Dimension XPS R400.  I need to know where to purchase a compatible one.

This adapter will allow you to use a Standard ATX power supply with your Dell computer...make sure the dimensions of the new power supply will fit your case. This adapter has been used for many a Dell as their proprietary power supplies are low powered and noisey. Any inexpensive 300-400 watt power supply will be far superior to the factory unit.
older dells use proprietary PSUs..... you'll want to get in touch with dell, most likely.  see below article for info.

it does not just have to be older dells, newer ones are the same.  arggg.   So as justintx has suggested you will have to get one from dell so they can rip you off again.

Or follow the suggestion at the link justintx supplied.  Replace both PSU and motherboard.
nice find t.
Hard to find but they work very well, and generally much less expensive than the oem replacement even with the added cost of the adapter. I try to keep the link handy...:) T

you bet, that is where Dell makes all their money.  It sure ain't from the computers , it is all the upgrades people do.
