Upgrading XPS T500 power supply
My trusty 4 year old XPS T500 came with 200W power supply. This power supply is currently supporting: 2 Maxtor IDE hard drives; Atlas Quantum 35GB hard drive; Adaptec 19160 SCSI card; Pinnacle DV500 motion picture editing card; Modem card; AtiRage128 Pro 16 MB AGP video card; Promise Ultra 100 card; Sound Blaster Live!
I suspect this is already a high load on the power supply. I am thinking of adding a fourth hard drive, an IDE, along with a removeable drive drawer, so as to extend my boot options (i.e. want to boot from Win98Se, Win2000, Win XP, and find BootMagic a bit underpowered for the purpose).
To guard against overwhelming the 200W power supply, I have purchased but not yet installed a CompUSA 300 Watt ATX power supply, that says it supports Pentium 4, complies with ATX ver 2.03 and ATX12V version 1.3.
The CompUSA power supply fits in the power supply bay perfectly well. HOWEVER, the P1 connector that supplies power to the motherboard has differently colored wires than the original power supply.
My question is: Do the differently colored wires matter ? Am I at any risk of frying my system if I install the new power supply ?
Will greatly 'preciate technically competent answer to this question.

Your XPS T does not use an ATX standard PS, so don't bother with the one from CompUSA. Dell likely won't have a 300 watt made for that system.
You might wish to check with www.pcpowerandcooling.com and look under their "Dell" mfr'd supplies, which have the connects you seek.
The P1 / 6 pin connector is indeed Dell proprietary. I might also add that I've never seen nor read of a Dell supply failing from such an "overload".
Good luck

Dear NVRambo:
Thanks much for the info. Being an extra cautious type, I think I'm really pushing the envelope having 4HD plus an extra fan... most likely you're right and I'm wasting my money, but I really want to protect my system, old though it may be, since I'm comfortable with it and it runs all the progs I want to run. If I were more diligent I would look up all the power draws and make the decision based on that...
Regards
Bob L.

After years of steady service, the power supply on my 1999 Dimension XPS T-500 failed today. Had to find an exact replacement and had to resort to Ebay. The links above are out of date and Centrix and PC cooling do not sell a replacement. The part numbers were NPS-200PB-73 M and DP/N 0009228C Rev. no 1. Quite a few were listed on Ebay, but few showed the proprietary P7 connector with 3 blue and 3 black wires. I bought one this afternoon for $18.00 but saw one refurbished for as much as $79.00 - more than I wanted to spend.
I've done lots of upgrading to this computer; it's running a sleek flat screen monitor with XP pro, I've added a 120 GB hard drive, installed a Promise IDE controller, got the old turtle beach sound card sounding good, but then upgraded to an Audiophile 2496 anyway, modded up to a Gloria II video card - the Riva TNT recently failed a memory test, oh and yes, power lept to 1.4 gz and added a card reader to one of the 3.5" bays. Added PCI cards for internet (after dial up was finished) and usb & firewire ports.
I fiddled a little with the rear keyboard purple connector today and the failure happened right after that. Black screen, no beep, fans running for a while, but then those died - Hope it's not the motherboard. Would like to keep this one working. Is this why PC sales are down? It saves money and is quite fun to keep fixing them and modding them out to the to the max! A computer from 1999 and a 2012 thread - I would say is a success for Dell.

Turns out it wasn't the power supply. It was the Powerleap upgrade. Took it out, reinstalled the original microprocessor and whoosh, the thing started up. Later swapped back to Powerleap. On the Powerleap, I adjusted the umpers for 100 FSB and 1.6 Volts on the other jumper. Got a few more freezes, but putting the old microprocessor in always got it to start up. Put Powerleap back in and everything is OK for now - so the power supply was fine, and now I have a spare.
