Dell XPS 8300 - Upgrade PSU?

This question is answered

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?

 

Thanks!

    The Mushkin Enhanced Joule MKNPSJL1000 1000W, power supply has a EPS/ATX12V 4+4-pin power connector that separates into 2 x 4-pin power connectors, that means either 4-pin section can be used for the motherboard's 4-pin PWR2 connector.

    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.

  • Fast response! Thanks so much. I just wish the PSU provided actually worked as expected. Now I have to waste $50. Bad Dell. Bad. :(

    How about an adapter for the second plug?

  • 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?

  • installed it a few days ago and the dimensions works out.  it's a bit tight with the usb port area but otherwise, worked out well.  

  • Awesome - thanks for the information.  I assume that PSU can run just about any single gaming video card available today.

  • it should.  check out newegg.com for the power supply cords that comes with the card.

    The Dimension 4550,8300,8400 like the GX240,260,280 in the Skydive Chassis will not fit a Generic power supply unless you cut a hole in the case using a nibbler tool or right angle tin snips.

    The area where many power supplies have the AC input is blocked by metal.

    You insert the right angle tin snips or nibbler tool in where the power cord goes on the case and cut a Line to the

    fan grille, continue along the grille and back thru and around back to to where you started until you have a large rectangular hole.

    If the power supply back looks like the one below the hack mod is not necessary.

    Later models like the GX520 and 620 etc have the Large Rectangular hole in the back so

    that a generic power supply will fit.  Without cutting the hole 2 things are wrong, 

    1.   the power supply may over heat and will not mount via the screws in the back.

    2.  The power cord will not go in because its blocked by metal and the switch on the back wont allow the power supply to be mounted.

    Note 2 Models from PC Power and Cooling.

    One Generic and One Specifically for the Skydive Tower Case. The Generic one with Switch on the back needs the hole.

    The DELL supply from PC Power and cooling Below does not need to any modifications to the case in order to fit.

  • no cutting needed for the xps8300 with the thermaltake 775 that i ordered.  

  • From the images I see on the thermaltake 775 Site I would say you DO have to cut a hole.

    Note the Position of the offset Screw that is directly under the NEMA C13 power connector.

    You could open the power supply case and remove the switch and it might fit but without at least a minor mod its definitely not going to fit unless they make a model that is like this.

  • i guess i lucked out because i have the dell power supply as per your picture.  so no mod needed.

  • Dell's Tiny hole with most of the metal blocked on the back is non standard.

    PC Power and Cooling no longer makes "Dell" specific models because newer model dells have the large hole in the back.  

    The Switch and the position of the AC input are the issue.  The holes where the screws go to hold in the power supply

    are standard.  If you look at the pictures you can see where the AC input MUST BE.  It has to be right next to the one

    screw that is offset from the corner instead of being at the corner.  Note that there are 2 not 4 screws.  The other 2 are handled

    by tabs that stand out that you align the power supply to.
