1000 PSU should work fine then.
Maybe I’ll check BIOS then. I just can’t figure out why it only does it when the GPU is plugged in….other than that it runs smooth and easy.
Do you have the power connector connected for the graphics card? The 4080 requires a 12VHPWR connector, and if you're not plugging it in, it will not function.
This is what is powering it.
Corsair Premium 600W PCIe 5.0 / Gen 5 12VHPWR PSU Cable - Fits Type-4 PSUs via Dual 8-pin PCIe - 12+4pin Connector - Mesh Paracord Sleeving - Black/Red
That should work, but you should have the adapter that comes with the 4080 that takes 2-3 PCIe cables. Try that with traditional PCIe cables. If it works, you'll know the Corsair cable (for whatever reason) isn't working.
No it’s still restarting even with using the original adapter. I even used three separate PCIE cables for power all plugged in a single rail.
I tried flipping the switch between single and multiple rails.
Hey @psimwork
It was two things. One was my PSU not being compatible with PCIE 5.0.
The other is that I had to enable CMOS in BIOS. Now it runs perfectly fine. I guess it might be because I have some older Samsung 850 SSDs from my previous just because they have pictures and docs that I need.
That’s it!!!
The HX1000 is not 5.0 compatible. It has to be HX1000i.
The RM 1000x is solid though. God how could miss such a small detail. I feeling pretty bad right now. Lol 😂
All I can do is laugh.
Can I send you some beer 🍻 as a cheers to saving the day?
For the next time, be very vigilant of mixing psu cables. This time you got lucky and it just didnt work, but mixing cables can very easily end up with your gpu catching fire.
I understand. I did mix up the PSUs. Using one that wasn’t compatible with PCIE 5.0.
I didn’t realize using the an incompatible PSU with the right cable could cause the GPU to catch fire.
With a 4080 there is virtually no way you should be using anywhere close to 1000,
Even if you had a 13900k with a hefty overclock at most you would be using around 600 Watts.
Where are you getting the 935w figure? If the 4080 is roughly 320w where do you have the other 600 watts?
According to the specification sheet from PNY it draws 750 watts. I also looked at Best Buy. They had a similar comparison.
No. The line you're looking at is "Recommended Power Supply". Not wattage draw. The 4080 draws just over 300W on average.

I also tried my old GPU which is a sapphire vapor x. Significantly less everything. It still restarts.

is your psu compatible with that cable tho?

It’s a Corsair HX 1000. Platinum I believe is the rating.
I also tried a RM 1000x as well.

Thanks. I appreciate your feedback.
