PC Graphics

[DavidPCNoob]

my first ever build and I need 3 pcie connections to the Gpu, my psu ( MPG A850G ) comes with a 12VHPWR two 6+2 pin pcie cable, would I be able to use this cable for my Gpu? All help is much appreciated thanks for reading!

My Gpu is ASUS Tuf 7900Xt OC

Couldn't find anything called Mag A580G but I found an MSI MPG A850G. Is that the one you have?

would I be able to use this cable for my Gpu?

What's your GPU then?

Your power supply has six 6+2 PIN PCIe connectors so just use one of them.  A 6+2 cable can easily be bought anywhere.  I would not advice you to daisy-chain any 8-pin cables to the GPU. 

But you should consider a PSU with more Watt.  While your CPU is the brain in your PC, the PSU is the heart.  You do not want your PSU to have a heart attack by being overloaded.  Your GPU alone requires a 750W PSU and then there are other components in your PC too which requires power.  Besides, power requirements will only increase in the future, especially for GPUs.  I would recommend a 1200W PSU, at least.  A PSU does not draw more power from the wall than it needs anyway.

Have you also tried asking on the msi community forum, someone there will probably have more knowledge on correct connection setup.

Yes I have posted on the MSI community forum thanks for the suggestion, my problem is the Tuf Rx 7900 xt needs 3 pcie and my PSU ( MSI MPG A850G ) only has 2 spare, meaning I’d have to daisy chain one, or there is a 12VHPWR Connection that has two 6+2pin pcies on, but I’m unsure if I can use the 12VHPWR for my GPU.
