So I was one who got the XPS 8300 before Dell stopped selling them.However, even though the PSU is rated 460W, it cannot even run my GTX460 (which requires 450W) because there is only 1 extra connecter to the PSU while the GTX460 requires 2 6 pin connectors. Very frustrating. So I am looking to buy a new PSU - is it safe to assume that any ATX PSU with sufficient wattage / amperage will work in this case? And so long as the PSU does not have a switch?
Solved! Go to Solution.
Most generic standard ATX power supply units can be installed, with either a 24-pin or 20+4-pin main motherboard power, as the XPS 8300 has an open back panel, with or without the on/off switch.
You should be able to buy a compatible power supply from either a local or online computer store.
Note: A power supply with four SATA power connectors, is needed.

Both plugs fit into the GTX460, but the problem is that they both come from the same cord. That is, the cord from the PSU ends in a 6 pin PCIe, and then coming out of that plug the wire extends an inch or 2 and ends in another 6 pin PCIe plug.
As a result, I don't think the GTX460 is getting enough power over the single cord. the PSU is rated 12V-A 18A, 12V-B 16A, 12V-c 8A. The card needs 24-32A. It can't get it over one single connector from this PSU.
i am looking to do the same.
just ordered a thermaltake 775watt power supply. 6.3" x 5.9" x 3.4" is the dimension.
anyone has used this on the xps 8300 and if it fits and works with the gtx460?
thanks in advance
Hi chochocho, how did the thermaltake 775 work in your XPS 8300? I'm also looking to upgrade my XPS 8300 PSU for an AMD 6990 or equivalent video card. Thoughts?
