OptiPlex 7020 internal power cable

Re: The cable I bought is a one into two splitter so the output from the psu can feed both into the motherboard and the graphics card.  You can send link of splitter extension cable.  It is probably the wrong cable to use any way.  If you are using an 8 pin to 8+8 pin splitter, the pinout is for standard 8 pin PCIe only.  not aware there is such a splitter cable that can feed Dell proprietary 8 pin as well as gpu 8 pin PCIe.

Dell oem psu cable has proprietary 8 pin and standard cpu 4 pin and both are required for motherboard.  to power a discrete gpu using 6 pin you would need either a Dell 315/365 w psu upgrade for XE2 SFF/MT respectively or use a standard 24 pin ATX psu plus a 24 to 8 pin adapter.

Hi and thank you. This is really helpful.

The splitter is: EasyULT Graphics Card Cable, Power Adapter, 8 Pin to Dual 8 Pin (6+2) PCIe GPU Power Adapter Cable, Graphics Card Power Cord or Graphics Card Power Extension Cord

The splitter link via Amazon is here: https://www.amazon.co.uk/dp/B09DPQ6F22/ref=pe_27063361_485629781_TE_item

You're right on the PSU output cables. See the pic of inside my PC.

This also shows the power socket on the graphics card.

You help by saying you dont know of a Dell adaptor or power cable that will convert to a regular power cable. Dell uses a cable with proprietary 8 pin - oh why did you do that to me Dell? I'll try and find one but wont hold my breath. It helps loads with your comment which I would never have known. Sadly it probably means I'll have to send the graphics card back and give up on my game play ambitions. If you have any ideas, then please let me know.

Thank you very much for your help. Best wishes, Peter Davies

Re: Power Adapter, 8 Pin to Dual 8 Pin (6+2) PCIe GPU Power Adapter Cable

that is what I thought you got.  It is not going to work.

Dell 8 pin

Dell 365W psu for XE2 has a 6 pin which you can convert to 8 pin for your gpu.

HU365EM-00 D365EM-00 07VK45 7VK45 0T1M43 T1M43 8pin + 6pin + 4pin

or ATX psu 24 pin and 24-8 pin adapter

Thank you. I'll explore buying a free-standing external PSU just to power the graphics card.

Hi again RedXPS630,

Do you know if there is a Dell power supply unit that I can buy to replace mine that will fit the motherboard but as well have a standard power plug to drive the graphics card please?

Thanks, Peter

Thank you red, That's been massive help.

 Best wishes, Peter
