Hey everyone! I've got a bit of a dilemma with my setup. I recently purchased a Gigabyte RX 9070 XT (Gaming OC 16GB) that has three 8-pin power sockets. My power supply unit (PSU) is an older be quiet! Dark Power Pro P10 with 750 Watts.
Currently, I have two cables and one adapter from my previous Asus ROG Strix RTX 2070 Super:
- There's a 12-pin PCIe cable that splits into two 6-pin "VGA1" connectors, plus a 2-pin dangling from it.
- I also have a 6-pin PCIe to 6-pin "PCIe/MB" cable.
- Lastly, a 6-pin to 7-pin (?) adapter.
Unfortunately, I no longer have the original box for the cables, so I'm unsure if this setup will work fine for the new graphics card or if it will lead to any problems. Can I at least power it up like this and just order a proper cable later? I had a chat with Al, but the advice wasn't very clear. He suggested a replacement cable with the code CP-6620.
Just to update, I decided to play it safe and replaced my PSU with a Corsair RM1000e, which gives me all the right cables I need! Better to be cautious, right?

To connect your GPU properly, you definitely need three 6+2 (8-pin) cables. Each of those should plug into the GPU's power sockets. Just a heads-up, the way they connect to the PSU can differ by brand, but most modern PSUs will support this configuration effectively.

Yeah, exactly! The two 6+2 cables plug into a single 12-pin PCIe slot on your PSU, while the 6-pin connects to the same but only uses 6 pins. Make sure they're all wired up right!
