Dell XPS 410 PSU upgrade help

I have a Dell XPS 410, I thought that it was great until I found out Dell cheaped out on the PSU and gave me a 375 watt psu for a gaming computer about a year ago. So, I think Dell is a bunch of money hoarding men, aka capitalism, but that is besides the point.

I want to upgrade my PSU to a higher wattage (At least 450, aiming for 500-750) so I can support the nvidia 9 series cards.

I measued the PSU that I have now, it is 140 x 97 x 150mm with an 80mm fan. These measurements are rough, I didn't take the actual PSU out, just the side panel to look at it. I might have got those numbers mixed up, but to me it seems like Length Height Width. What really aggrivated me is that those numbers are correct for a standard ATX, all except the hieght which is about 1cm (10mm) higher than most. I don't know what to do now, all the PSU I look at don't fit. So, either can someone help me with finding a new PSU to fit and/or helping me figure out if my mobo will work in another case.

If they put up a power supply that can run your PC fine then i dont see where did they cheap out?

As for upgrading ya you should have known this before buying dell rather than blaming them cuz it's not like they lied to you or soemthing since everybody knows that upgrading is a huge pain with dell and pre-builts in general i think that's why most people avoid it.

Sadly, you're going to be out of luck. My roommate has your exact machine, and tried to do exactly what you're trying to do. You can't buy a PSU from someplace other than Dell that will fit in there. Even worse, open your case and take a look at that board. It's backwards as compared to every other board in existence. i.e. - you can't put it in another case. You're pretty much screwed. When my roommate found that out, he decided to sell his XPS in favor of piecing together something a little more upgrade friendly.theragu40

Dell motherboards are indeed proprietary, but I do believe that's just the now dead BTX standard. You can try moving it onto a BTX-converted case like say a Stacker 830, but I don't know anyone who has ever done that before.
