Ok, I've heard a lot about how Dell makes strange cases that only their PSU's Fit in.(that sux) I recently got an XPS420 it's great, but i want to upgrade the graphics card, but low and behold, I need a new PSU!!

What PSu's would fit into an XPS 420? Give me some suggestions!

  1. Dell usually makes their cases themselves so a lot of times it hard to put third party products inside. You may have to buy another case and put everything in there.
  2. Almost any standard ATX 2.2 unit will work.
  3. Anyone else have any input on this? I am also looking to upgrade the power supply in my XPS 420 and want to make sure I get something that fits in a BTX case.

    I'm looking at a CORSAIR CMPSU-520HX ATX12V v2.2. Will this work?
  4. Here's what a 620HX look like in an XPS 410 ( same box basically )

  5. Visit http://www.pcpowerandcooling.com

    They are the ones that make the Dell PSUs. (Actually OEM'd through Seasonic)

    They sell Dell Specific PSUs and should be able to tell you easily which of their PSUs fit in which models. (Or so I hope.)
  6. OK, now I've heard that the stock Power Supply that comes with the 420 (375 watts!!!ugh) would be able to handle the 8800GT?
