So as title suggests I purchased an MSI A1000G about a year or so ago but never got around to using it, decided to use it in my new pc build but have come across a problem with said power supply to gpu, PSU has 4 pcie slots currently, 2 are being used by CPU and 1 by motherboard for excess power to PCIE/panel, looked at MSI suggestions and they suggest using a VR12 to 2 x 6+2 pin and a seperate 8 pin to power the 3 x 8 pin GPU, problem is I never had a 12vr to 2 x 6+2 pcie cable with the psu, i have a 12vr to 16 pin one for NVIDIA cards but since swapping to amd i'm in a bit of a pickle.

is there anywhere I can purchase both a 12vr to x 2 6+2 cable and a seperate 8 pin as i've currently got only 1 unused pcie slot left on this psu and it seems to be the only way I would be able to power the GPU other than a pcie to 3 x 8 pin which seems really unsafe and don't wanna risk such a situation.

thanks in advance!
 
Is it a A1000g PCIe5 or A1000G model? only the PCIe5 has 16pin connector.

but look like you have 7 connectors? Can you check your included cable again?

It’s an A1000g pcie5, but ye definitely only got the 12v to 16 pin haven’t got a 12v to 2 x 8 kinda bummed out as can’t see any other way to power gpu without one and cant seem to find any online anywhere.

Only cables I have currently are 3 x 8 , molex and sata, 24 pin mobo and vr12 to 16 pin.


Seem to be missing the pigtail? Which would be the only other way around it but would require me unplugging an 8 pin from mobo that powers excess pciE power? Or am I getting confused somewhere.

Seem something is missing in the package as website describes you should have a 16 pin to 2 x 8 pin adapter (in A1000G PCIe5)

Better just write a ticket to MSI and explains the situation.
But for now, you can unplug the one going into motherboard PCIe power and use it for GPU. The onboard PCIe power is not mandatory and you only need to connect it when you use multiple GPU or power consuming pcie device.
