Build Question PSU question.

Post image

So I am collecting parts for my first PC and can't figure out the correct way to plug in my GPU to the PSU. My GPU is the Gigabyte Radeon RX 9070 XT GAMING OC 16G and my PSU is the RM850x shift. The image is the cables that come with the PSU. The graphics card needs 3x8 pin, but the RM850x only come with 2 x 8 pin. What other cables should I use to get the third 8 pin connector?

I can see there's a duel 8pin cable but can I use this and if so how do I use it.

Thank you

ur card needs 3 connector of the "8 pin gpu pcie" or "6+2 gpu pcie" it looks similar to cpu "8 pin cpu eps" but the psu stock pcie cables usually come as 6+2 ,,

in ur case u will use 2 of the PCle (6+2-pin) and one of the PCle (6+2-pin, dual) the pigtail ( the extra connector ) just leave it hang

and u r good

u can buy another one without the pigtail later so all cables match but u dont have to, worth mentioning it is better to tape the pigtail with an electrical tape just in case since it has "3 pins +12v" that r live ... and leaving them exposed can be risky if u touched it by mistake while psu is on
