ASUS 5090 Astral OC Edition
MSI MEG Ai1300P PSU – Using the factory included MSI 12VHPWR cable
Had some time today to play with 3D Mark Nomad to to see what this 5090 can do and it looks like im pulling to much power per pin according to HWiNFO. The first pic shows pins 1 & 3 pulling a bit to much. this happened about a full 2 seconds into the steel nomad run, i shut the test down once i saw this.
So i shut my pc down, unplugged it from power, opened it up and first checked the PSU side of the 12VHPWR connector. I pulled it out and it looked fine, plugged it back in firmly. Went to the GPU side and unplugged it. Looked good as well, no damage so i plugged it back in firmly.
Ran a second Steel nomad with the overclock on the core only and on this run HWiNFO showed pin 6 pulling to much albeit not as much as on the first run. Decided to run another steel nomad run at stock core clock and once again it pulls to much power on pin 6.
So now that i have explained this, do i still have this connector not quite snug enough someone, bad 12VHPWR cable? Are you 5090 owners getting this on your steel nomad runs?
PSU is 5 months old, bout it new from MSI so it has warranty if thats the direction i need to go or i thought trying an aftermarket 12VHPWR connector from cablemod, one of the stealthsense cables, never had an issue with cablemod before. Not sure where to go from here so i thought i would seek some advice.

Undervolt and pray. That’s all you can do. Unless you have a good warranty (like a Microcenter plan on the thing). It’s a design flow. You can’t do anything about it. Use it or sell it.
2 seconds of 10A instead of 9A is never gonna melt anything.
You can purchase seasonic’s 12v-2×6 to 12v-2×6 connector. If a PSU has a 12v-2×6 or a 12VHPWR connector, it’s a standard connector or else it would adapt from different connectors. You can use a different 12v-2×6 or 12VHPWR cable as long as both heads of the cable are that port and not adapting from 2x 8 pin or other formats.
It may just be a weak cable and this may be your fix that’s cheap. Also don’t get 12VHPWR cables from cablemod. You don’t know what dud you’re getting your hands on by accident.
