CPU Stock Voltage issue

Guthar · July 29, 2019

Hey guys, quick background info: I bought a 2080 and put it in my Alienware Aurora R6. The stock PSU is 460w and I thought I better upgrade that as well to. So I picked up a Corsair 650m. While installing it I noticed that my motherboard has the GPU-PWR 8 pin connector as well as the normal 4 pin CPU connector. Which became problematic. Dell has these proprietary connectors with their PSUs and I ran into a problem and wasn't able to use the new PSU. My PC runs fine with the 2080 and stock 460w PSU. Tried some games and did a few benchmarks on 3dMark. Seems to be running fine with the underpowered PSU. No crashes or anything out of the ordinary. However I did notice my CPU temps have jumped quite a bit and was wondering if that is due to the lack of power. Idle temps on the CPU (which is stock air cooled) jump from 50-60c. CPU is a i7-7700 btw.

While under gaming load temps would run in the mid to high 70c range. Tried Prime95 and it would sit around 85c. Idle voltage for my CPU is 1.110-1.600v

I've done some research as much as I can and I don't really know if the voltage is off on the CPU. Everything else seems to be working normally. GPU is idling in the 45-55c range. While under full game load it doesn't get above 70c.

I guess my question is; is this normal? My gut instinct is just to go out and finally upgrade the rest of my PC. I would need to buy a new Mobo because of the PSU issue and I would hate to get rid of the 7700 simply because I think it is just fine for me right now. I don't really want to do it, but I can't think of a better excuse to make the jump to a 3700x. My wallet isn't going to be happy with that, but I might say screw it.

Any insight would help a lot.

You added a whopping great big GPU which is also pumping out heat into your case raising the ambient temperature. Dell cases aren't exactly known for having good air flow.

Do you think the PSU is even a problem then? I'm leaning towards just being safe and buying a new case/mobo/cpu today and putting my mind to ease. I want to go with a 3700x but I have a tight budget and I know there are Mobo issues with those chips right now. What would you recommend for a Mobo for that CPU that likely wouldn't have the bios issue that I hear about. I don't think I can afford the $200+ mobos that seem to not have issues.

Honestly, if you're seriously considering upgrading then make another post innthe new builds section, state your budget, state what you need for that budget and say what you'd like to get.

Fyi my mobo cost me £280 and I'm having problems with my 3800X, I think right now everyone is. Just remember that these kind of issues are common with new hardware releases and will be fixed with time.
