Why not a new case too? I do not remember the particular of this system, but Dell has a annoying habit of using proprietary PSU's for their builds.

Btw, what MB does it have? something along the 45 line and ddr2 800/ddr3 1066?

As with any dell case, their power supplies are often proprietary or they are a weird form factor shape..with only a few connectors. I cannot comment on that one replacement as lord only knows what brand that is or any sort of quality with it. 400Watts would certainly be enough power..but I couldn't find anything on that model specific to its PSU sizing/requirements. If it doesn't fit a standard PSU format then your options are limited to dell specific replacement power supplies or offbrand 3rd party ones probably from china.

Thanks. Did you look at the link? Would that one suck?
And also, do you think i would be able to squeeze by with the 305 watt i already have?

I don't know who makes that so I'm really not sure..you could always check to see if dell sells any replacement PSU's for that model that are higher.

The Q8300 has a max TDP of 95w whereas the e8400 has a max TDP of 65watts. It might be cutting it close..but you might be okay.

do you have a dell link that actually shows this mini tower? They usually refer to case sizes such as SFF, USFF, etc. You probably will be fine with your current PSU as the TDP isn't that far apart from what you currently have..BUT if you can upgrade I'd like to be able to find the right size..as dell cases never play well with typical after market parts that aren't dell branded.
