Power supply suggestions for my XPS 8700

Jump to solution
My 8700 came with the GeForce GTX 745 and I'm looking to upgrade to the: Nvidia GeForce GTX 780 EVGA Classified Edition ACX Cooler 3Gb GDDR5 It requires 2 eight pin power connections and I'm not sure which oower supply will work, too many options. It recommends at least a 600w power supply so I'd be more interested in a 700w or more to make sure there is not issue. Thanks in advance for any advice! Rob Mesa-AZ

en.community.dell.com/.../19611037 has many examples.

Sasonic X-650 is my go-to standard, and is more than enough for any single graphics card.

Do you already have the GTX 780? If not you might consider a GTX 1060 6GB gaming edition. The newer cards are more power efficient and I think a GTX 1060 is roughly equal to a GTX 780.

A GTX 1060 will work with the OEM power supply. Some GTX 1060 cards need a single 8 pin and if the card does not come with a dual 6 pin to single 8 pin reverse Y adapter, they can be found on eBay for about $7.00 USD shipped.

The other downside of a GTX 780 is the heat from the card. I ran an overclocked GTX 770 in an xps 8700 and it got hot. I cut the front of the case and added an intake fan and it helped, however after upgraded to a GTX 970 it ran much cooler.

The GTX 1060 is slightly faster/more powerful than the 970 and it produces even less heat than the 970 so it should do fine with the stock 8700 case.

good luck. post pics on the thread above when you do the upgrade.

Since you are not gaming, I would look at a GTX 1050ti. It will easily work with the stock power supply. 

edit: Just looked at the MSI GeForce® GTX 1050 Ti 4GT OC and the power draw is only 75W and does not use a PCI power connector. All the power will come from the PCIe slot.

I've had good success with MSI cards, but EVGA is also a solid brand.

This one looks pretty good for the price: ( copy paste the next line into google

MSI GeForce GTX 1050 Ti DirectX 12 GTX 1050 Ti 4GT OC 4GB 128-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready ATX Video Card

one DVI-D, one HDMI and one DisplayPort v1.4

$135 after rebates at new egg. amazon has it for $140 after rebate.

note:

You MUST upgrade the 8700 BIOS to A10 (win7/win81) or A11 (Win10) for any GTX 9xx or GTX 10xx cards to work, and to be clear you need to update it before you install the card or you will get a black screen.

If you are on a budget, you can sell the GTX 745 on eBay for around $50 ( maybe more). After shipping and selling fees it might be $40.

Great info Dan,

I'm having a hard time finding a used 1060 but did find the 780 (have not purchased it yet...  looks like I need to hunt for the 1060.  FYI, I'm not a gamer, it's needed to run a 2K Samsung 32" WQHD monitor with a ham radio set up with some demanding software but nothing like gaming needs so maybe there is a better option for a video card? Needs to have a Display port with at least v1.2 config. Thanks

Again, great input Dan.  Amazon has it for $149 and I can have it tomorrow and no power supply update needed, sounds like a winner.  I'll be sure to updat the bios to A11, it already has A10 ( currently running Win10)

I'll post picks when it's done!
