Power supply help (again)

By markschu ·
Hey guys. I have asked some questions concerning upgrading my Dell power supply before and I could use some more help.
I have a Dell XPS 200 which is a small form factor case and the PS is 275W. There is NO larger PS that will fit this case, and I am not ready to build a new system, as I spent close to $1500 on this system in 2006. It has a 3.2 GHZ dual core with 3GB of RAM and I also just put in a 1TB HDD so I do not want a new system for a couple of years again.
I have also upgraded the video card to an ATI HD 2400 PRO which is supposed to require a 300W PS but runs fine most of the time. What happens is, whenever I use my Microsoft XBox 360 wireless adapter (usb) or sometimes when I am running Beyond TV (resource HOG), my computer will shut down. I know this is because I am drawing too much power and my PC is getting too hot and then failing. If I am just running basic programs, it runs fine.
What I am going to do is buy a larger PS (with the Dell PS adapter) and connect it outside my case. I realize this is probably slightly dangerous, but I have no other options left (thanks Dell).
I'm thinking I will gorilla tape (strong duct tape) it to the top of my case and buy longer cables if necessary. I am not worried about anyone getting electrocuted (except myself of course, lol) because, I live alone and no one really comes in close contact with my PC. I also have a air compressor in my shop and open and dust my PC weekly, if not almost daily.
I would like some advice, however, if anyone has ever done something like this (installed a PS outside of their case) and can give me some help or pointers. Or, if there are other options to increase my power so I can avoid anymore power failures.
Thanks guys!

now that is...

pretty cool. OK. Here: it shows the comparisons between cases, with the motherboard compat. on top on the right. However, it does not have a cat. for BTX, which we have established I own. Could you please clarify if I need to have a case that specifically says BTX, or if I can use a different size. Maybe I should email Antec? *What was my first clue, right, LOL*

No here you should use a BTX Case

by OH Smeg In reply to now that is...

Well at least I would.

I'm not a lover of using adapters in any form and I wasn't suggesting the Skeleton for your needs here just responding to a comment about a Perspex Case above. :)

Personally I would be surprised if Antec doesn't already have something on the Drawing Boards for the BTX M'Boards but as things stand currently I would stick with a Real Case as these provide protection from RF and other sources of Interference that may prove difficult to deal with under other circumstances. A computer case is still a Faraday Cage around the Internal Components that bleeds off any thing that it collects to Earth so it's Important to have a Working Earth Connection here.

you guys...

are all full of...wait for it...GREAT ideas! Thought I was going to say something else didn't ya? ; ) I finally realized (at about 3AM) that all I really needed to do to insure the least hassle was to look at the bigger XPS models above mine! I found that these power supplies were not only bigger, but had the same voltage settings, thereby allowing me to bypass all adapters. Take a look here:
As you can see, the 3 connectors that I need are identical to the 3 on the 400 PS! The only concern I still have (I was going to start a new thread actually) is that under the first connector (DC Power Connector P1) 3 of the wires use 22 gauge and on the 400 PS they only use 18 gauge. Do you think this will matter? I could always crack open my old PS and attach the wires to the new PS maybe? Waddya think braintrust?

Set it in the bottom of the case

by john3347 In reply to Power supply help (again)

I had a pieced up computer one time that didn't allow the power supply that I had available to fit in the space provided in the case. I did, however have a suitable space in the bottom of the case. I just set the PS loose and let 'er rip. If you have the space, but don't feel comfortable with the box "bouncing loose", secure it with some double stick tape - the thick stuff that is about 1/8" thick. If memory serves me correctly, I had to lay the power supply upside down to avoid blocking the fan. I didn't have any overheat problems with that particular setup caused by the power supply not venting outside the case.

p.s. I don't remember now, but I probably removed a PCI card slot cover to run the power cord.
