Hi all, I just recieved my Dell XPS 8700 and it is an impressive machine. It didn't take long to figure out that the 7570 was acting as a very significant bottleneck relative to the processor and RAM capabilities, so I've been thinking I'd like to upgrade the video card. The question I have is this; the 450W power source seems sufficient for most mid-range cards (<$200), but I don't know about the amps. I was taking a look at the 650 ti boost from EVGA, as it would complement the factory hardware from Dell quite nicely, but am uncertain if the power supply that shipped with the 8700 can handle a good mid-range card. Opinions?
Single 12v Rail
+3.3V@30A, +5V@30A, +12V@62A, -12V@0.8A, +5VSB@3.0A
A dedicated single +12V rail Over-voltage and over-current protection, under-voltage protection,
and short circuit protection provide maximum safety to your critical system components

The minimum system power requirement for GeForce GTX 650 Ti is 400W. So the power supply shipped with your system would suffice.
Please reply if you have any questions.

I wanted to switch the gpu to a nvidia gtx 660 ti. its minimum power requirement is 450w. is it to much for the xps 8700?
XPS 8700 is shipped with 460W power supply. Nvidia GTX 660 Ti should work with the system without any issues. You would not require to change the power supply.
Hi - Can anyone tell me if this power supply is compatible with the XPS 8700:
I'd like to install a GTX GeForce 780.
Its too small. its very Dodgy about EPS 12v Version 2.93 Its made in china. If it overvoltages and destroys everything including but not limited to CPU, RAM, HARD DRIVE, MOTHERBOARD etc will you still think its safe?
25 Amps Max on the 12v rail is TOO SMALL for the GTX780.
The 780 requires an 8 pin and a 6 pin power connector.
This means 300W for the 8 pin PLUS 150W for the 6 pin PLUS 75W for the X16 Slot.
This means you need Guaranteed and Stable 528W for the 12v Rails NOT INCLUDING what the Processor, hard drive, etc needs from the 12v rail. 528W = 44 AMPS 12v
If you add up all the numbers 150+552+3.5+12.5 = 718 Watts
Here is where the problem comes in.
The 5v is 125W , The 3.3 is 82.5 W , The 12v is 300W X 2 , The -12 is 3.5W , The 5VSB is 12.5 W
= 823.5 Watts Total. The FCC label is Fake since there is no certification number listed (Which is required for it to be Legit) E243823 is legit for OCZ UL Listing
Wow, thanks for the info. Can you suggest one that would work for me in my XPS 8700?
Ok, great will check it out thanks!
I have a 8700 too. Let me know how that PSU upgrade worked for you and how the installation went as well. Thanks!
I am also a 8700 owner and thinking of upgrading
Not sure where we are with this but I just installed CX Corsair 750M (80 Bronze), got it for $80 on Amazon and it works perfectly. The 12V 8 pin is easily split in 2 for a 4-pin and there were no issues - still 12volts delivered.. Connected it to my brand new GeForce GTX 770 and everything is working perfectly. Hope this helps -- I went through alot of different forums that helped me get everything together - especially tom's hardware. Thanks.

I have some experience doing upgrades on some my old computers from years ago.
Was this a pretty simple project for you?
Did the PS drop right in?
Will the pin configuration be obvious?
I have a 8700 as well
