Upgrading PSU in a Dell XPS 420 with from 2years ago.

Hello

I was wondering if I can upgrade the PSU with my Dell XPS 420? I want to put a better GPU in it and I got some good suggestions from this site and I want to make sure that the PSU is upgradable with the MB.

Oh it is a Dual 2 Quad Q6600 2.4 GHZ 2.39 GHZ with a 375 Watt PSU

  1. You can upgrade with almost any standard ATX unit, most would reccomend Corsair, I would too except that there were plenty of compatibility issues between them and the 420.
    The Antec Earthwatts worked fine and are decent budget power supplies;

    The newer Antec TPN series should work and are better quality.

    Cool thanks. So this is a ATX size case? So in the future I can rip out the insides and upgrade with new MB and CPU?
  3. No, its a BTX case, so no MB upgrade.
  4. So I can only upgrade the PSU and GPU? I want to make sure, this is PCI-E correct for the GPU?
  5. Yes

    Cool, thanks. So I will buy a bigger PSU and get a good GPU. Will the Q6600 slow down my game play any? I have 4 gigs of Ram and I think it is DDR2 800.
    I am not sure. The system is in Japanese Vista(have to install English OS) and I cant find any answer searching online about what kind of DDR2 ram it is.
  7. It will hinder the performance of some higher power cards.
    If you're out of warranty and willing to do some modding you could pin mod the cpu to make it run at 3.0 and get a noticeable improvement.
    The ram is usually Hynix or Elpidia.

    Hello

    What is pin modding?
  9. Oh and someone mentioned that my Dell XPS 420 is a BTX case. Is this so? If so do I have to find a special sized power supply to fit?
    I opened the computer and it seems to be a full size MB in there.
  10. Here's the pin mod

    I mentioned the fact that it's a BTX case, and no, you don't need a special power supply.
