Works and fits as advertised

on 2/13/2007

I have a Dell Dimension 8200 and needed to bump up the original 250W power supply to 400W. Since the Dell case is not the ATX standard, I had to get a specific PS to fit the case. This one fits perfectly and runs just fine. The fan is just as quiet but starts to crank up once the heat from the PS starts to build a bit. The only complaint is that it didn't have as many 4 pin connectors that my original one had. Only 4 of the big ones and I needed 5. I hacked off a couple from my old PS and soldered them in to the new PS. Works fine. It was a little pricey compared to other PS's but hey, it fits my fancy Dell case! Overall, I'm pleased.

An easy upgrade for my Dell Dimension 8300

on 2/15/2007

This power supply was a little extra money, but worth it in the end I think. Other than having a bit of trouble lining up the screw holes, the new power supply went in without a hitch and had all the right connectors for my Dimension 8300. What this allowed me to do was to upgrade my video card to a 256MB GeForce 7600 GS card with its own power connector. It gave a very nice boost to my graphics performance.
