So I just bought a dell ( I know, I know, but I get a massive discount from work..so try not to rag on me too harshly ;)) And I am trying to install this graphics card:

ASUS Graphics Cards with ASUS Exclusive DirectCU Thermal Solution (HD7850-DC2-2GD5-V2)

It clicks in fine, and has the right port, but the dell doesn't seem to have a place to plug in the additional 6pin pci-e power supply. It has two free HDD Sata ports, and a bizarre 8 pin VGA power slot ( which dell had no idea on the phone what it was....)


~ Would it be possible to run a separate PSU just for the graphics card? I know ideally I could update the power supply, but Keep in mind that the power supplies on dells are really tough to replace (without just buying a new dell)

This thread from many years ago has the "Thermaltake Purepower Power Express" to gain the extra power AND the pci-e cable

Would this solve the issue? Is there a newer version of this now discontinued product?

~Or would it be possible to use the hdd sata ports with an adapter in order to run the card?



Specs:
Dell Precision T3600 workstation.
Intel® Xeon® Processor E5-1620 (Four Core 3.6GHz, 10M, Turbo)
425W PSU

Additionally purchased and installed
Samsung Electronics 840 Pro Series 2.5-Inch 256 GB SATA 6GB/s Solid State Drive MZ-7PD256BW

Link to the Dell manual:
Dell T3600
 
Solution
Try a Molex to PCI-E 6 pin adapter cable, though not recommended. And yes you could use an extra PSU for GPU, but you have to put a jumper to start the PSU.

BTW if the case/cabinet is 7" wide, then you can use a standard ATX PSU.

I've been thinking for this as well, yet I don't have the resources. If you were to get a PSU just for the GPU, and you have enough room for another socket you could just buy another ATX cable and slap it right into a socket (Assuming you have another socket or surge protector).

I'm not sure if you need a jumper for the PSU, since a PSU doesn't draw power if what it's connected to is turned off.
