Astral 5090 12VHPWR Issue?

Guys I was playing Control Resonant so GPU is running at max load. I recently swapped into a new Lian Li case with my GPU and Asus 1200 PSU I’ve had since November 2025 and I got the red blinking light. Apparently… I guess it’s warning me before cables got melted or started melting. I checked all ports, there’s nothing melted in them so I caught it early.

I’m currently using the ugly adapter that game with my 5090 in the meantime and it cleared the warnings and is running the game fine.

Should I use a Cable Mod 12V with separate two 9 pin connectors or another 16 pin can work?

What should I do here? I don’t want the run the ugly adapter setup, it’s too bulky.

Is there anyone in this subreddit who uses this cable for their 5090 Astral?

I current have a 1200w Thor P2, which is not an ATX 3.1 compliant PSU. I did buy this cable, but I have not turned the PC on with this inside my 5090 Astral.

Best 12v2x6 cable config for Corsair HX1500i 2025

I'm looking at getting a custom config cable for my 5090 using this PSU. I have a Wireview Pro 2 installed and my current cable isn't the greatest so would like to try the Cablemod.

I already know the length and type I need. The only thing I am not sure on is if it's better to have the 2 x 8 pin, 3 x 8 pin or 4 x 8 pin.

It seems like less 8 pins would make it easier to get a balanced connection, but more might be a bit safer since it spreads the load out. Unfortunately this PSU doesn't have the native 16 pin.

Does anyone have experience with this sort of setup and whether or not more 8 pins works better?
