[SOLVED] CPU power connected to GPU ?

[McCoffee]

I was swapping my GPU and power supply today
I accidentally connected a pcie power cable to what I believe is a CPU power connector on the EVGA G2 1000W PSU.
The connector fit perfectly and was not forced.

When I realised the error I swapped gpu and power connector as I did not actually have the correct VGA power connector needed for dual 8-pin power.

The system now bootloops to the bios and won't boot to Windows.

Any suggestions would be appreciated!

A little confused. This PSU has the correct PCIE power connectors for 8-pin power. This PSU comes with six 6+2 pin connectors, so it can handle dual 8-pin power for three such GPUs.

Let's get your full specs here. Hopefully, you have a CPU with integrated graphics (this is why it's strongly recommended to give full specs, so that we don't have to spend time figuring out what the equipment actually is that could be better spent dealing with the problem). Unfortunately, if you successfully connected a CPU power connector to the GPU and now the GPU doesn't work, it may have been fried. The wrong voltages coming into the wrong places leads to an extremely poor prognosis when something isn't working afterwards.

Tried a clear cmos?

The cpu connectors on the psu side are different from the pcie connectors so force had to be applied to get a pcie cable connector into a cpu connector.

can you use the above image and the clipping tool to show what connectors on the psu side you used with the pcie cable? Upload to Imgur and post back.

Full specs:
I5 6600k
Asus Z-270 P
8gb DDR4
EVGA G2 1000W
Gainward RTX 2080 Pheonix

I just set the GPU into my 2nd upgrade system and can confirm it works perfectly fine
This system is
Ryzen 2700x
Asus Strix x470
and the RTX 2080
Powered by a Corsair TX500M

I believe I nixxed up the pcie cables from the power supplies as the EVGA G2 uses different PCIE cables.


The gpu atleast works, think the motherboard may be a lil fried though?
Would it maybe be a CMOS or ram issue?
It boots to bios, and on exiting bios reboots to bios again

The keying seems to match corsairs pcie connector.
I'm trying to find power cables for EVGAs pcie/vga connectors but it's proving difficult

EVGA® – CableMod

(But again, the PSU comes with more than enough cables, so I'm very confused).

Never mix cables between brands.

Shouldn't mix Corsair with EVGA.
