Hello! It's been a while since my last PC build and I'm feeling a bit outdated. I own an Aorus Z790M Elite Ax Ice motherboard and I've noticed there are now 12 pins for the CPU power socket. However, my PSU only has an eight-pin CPU power cable. My CPU is an i9 14900k and I don't plan to overclock. Should I purchase a new PSU with a twelve-pin CPU cable or can I just use the existing eight-pin socket? Additionally, since I'm expecting an RTX 5080 in the future, I might need a PSU upgrade eventually. I don't want to replace my Corsair adapter in this build just to test it. Thanks!

My CPU is an i9 14900k, and I’m not planning to overclock it. Should I purchase a new PSU with a 12-pin CPU cable or can I just use the standard 8-pin power socket? Please include the specifications for my build in this thread, as changes could affect its relevance.

I have an Aorus Z790M Elite Ax Ice motherboard, and I’ve noticed that the CPU power connector now has 12 pins. However, my PSU only supports an 8-pin CPU power cable.

Following general guidelines for PSUs, if your power supply lacks the required connectors for your components, you’re either:
a) using the incorrect PSU for this build
or
b) using the wrong components for this build.

Just a note: regarding the EPS connectors on the motherboard, there are both an 8-pin and a 4-pin type. You should prioritize connecting the 8-pin one. If you’re aiming for high overclocking or adding an i9 processor, also connect the 4-pin EPS.

I’m planning to upgrade to an RTX 5080 soon, so a PSU upgrade will likely be necessary eventually. I don’t want to replace my Corsair in this setup just to test it.

Please share your current PSU details (make, model, age) and the BIOS version for your motherboard.

It's a straightforward inquiry, if the motherboard includes an 8-pin EPS and a 4-pin EPS beside it, can I rely solely on the 8-pin without overclocking?
