Hi everyone,
I’m looking for some advice regarding a direct 12VHPWR / 12V-2x6 cable for my PSU.
My power supply is a Gigabyte AORUS P850W (GP-AP850GM), and I’ve just bought an MSI RTX 5070 Ti Gaming Trio OC.
The GPU comes with a 3x 8-pin PCIe to 16-pin adapter, but unfortunately I no longer have all of the original PCIe cables that came with my PSU. I currently only have two.
Ideally, I’d like to avoid the adapter entirely and use a direct PSU → 12VHPWR / 12V-2x6 cable.
Does CableMod make a cable that is specifically compatible with the Gigabyte GP-AP850GM pinout?
I know modular PSU cables are not universal, so I definitely don’t want to risk using a cable intended for another Gigabyte PSU or another brand.
If a direct 12VHPWR cable isn’t available, is there a CableMod PCIe 8-pin cable that is confirmed compatible with the GP-AP850GM so I can safely use the original MSI 3x 8-pin adapter?
Thanks!

I noticed some green corrosion on one of the cables and stupidly continued using it. Today I smelt burning and saw the damage on the connector so I shut the PSU down. The GPU looks ok so I am hoping it wasn't damaged.

This is a CableMod 3x8 12VHPWR cable that is at least two years old.

Getting a new 5070ti from Zotac and I’m really wanting to use this Cable setup of this 90 degree 12vhpwr adapter extension with 2 PCIe Type 5 Cables plugged into my 1200 watt PSU from Cosair. Main function is that the 90 degree allows for a cleaner look going into the 5070ti.

After hearing so many horror stories about melting 12vhpwr cables and stuff like that, I just wanna run this by someone before I mess up a brand new card.

I do also have a non 90degree 12vhpwr cables from the PSU cable set and the squid adapter that came with the GPU. Pictures for those who need them!

Edit: SP

It already booted.

This rtx 5080 hod comes with a led debug light and it lighted white led indicating the cable is properly seated.

But is that bend safe though? It is so because the cable is short.

I’m trying to choose a new cable for my new ASUS TUF Gaming RTX 5080 OC, but I’m a little confused about the differences between ATX 3.0 and ATX 3.1 PSUs.

I recently upgraded my GPU from a 3090 Ti to a 5080. I also bought a WIREVIEW PRO II and want to pair it with a custom CableMod cable.

I’m not sure if the cable I’m looking at is compatible with my PSU. From what I understand, ATX 3.1 PSUs use the newer 12V-2x6 connector, while ATX 3.0 PSUs use the 12VHPWR connector. Please correct me if I’m wrong.

Does that mean the 12V-2x6 cable from CableMod would not be compatible with my PSU, even though CableMod lists my exact PSU as compatible? My PSU is the MSI MEG Ai1300P PCIE5 (ATX 3.0, 1300W).

Can someone help me figure out which cable I should choose and whether I have the correct configuration?

Also, regarding my PSU: would you recommend upgrading to a newer one? I currently have the MSI MEG Ai1300P PCIE5, which is a 1300W ATX 3.0 PSU and currently has about 4 years of use with my 3090ti. I was watching a YouTube video where they recommended buying a new PSU whenever you upgrade your GPU, but I’m not sure how true that is. Is there actually a reason I should replace my current PSU for the RTX 5080, or is my existing PSU good enough?

Can this even be paired up with the Wireview Pro 2 ?
