Constant Power to GPU?

[jsbollman]

Hey guys, I am new here. I came to ask a question regarding my PSU and GPU. The question will involve another component, but my main concern is the GPU.

 

I am currently running an i7-4790K, Z97-Deluxe motherboard, GTX 1080 TI SC BLACK Edition, 32GB DDR3 RAM by Mushkin, EVGA 1200P2 PSU, a Samsung 850 Evo SSD, and 2 Seagate 3TB hard disk drives. These components are housed in a Phanteks Enthoo Evolve TG case. 

 

I noticed it with my GTX 980, but moreso with my new 1080 TI due to the back plate, that when the PC is off, the power appears to stay supplied to the GPU. The back plate stays severely hot when off, and when I cut the main power via the manual switch on the PSU or from the wall, it shuts the GPU off and it cools down.

 

I tried brand new PSU cables. I have the official EVGA (Paracord?) White cables. I tried using one rail from the PSU, versus two. I re-wired the entire PC, thinking maybe I went wrong somewhere. I have been troubleshooting this for weeks, and more often now that my new $700 GPU has the potential to be destroyed. Is this normal? 

 

I ask because it happened around the same time I got the anniversary update on 10, received the PSU cables, and swapped cases. I did it all within the same few days. I just didn't notice it until I heard the hard drives running recently as well. Which is another part of the question. When the power is flipped on at the wall/switch, the hard drives kick on too. Normal? I am not an electrician, so I don't know exactly how to troubleshoot the voltage itself. I have a multimeter, but I am not sure what to look for.

 

Thanks,

Josh

How old is this Tier 1, 80+ Platnium, actually really high quality PSU?

That's probably standby power. It is probably trying to keep the vram so you can wake it from sleep. I'd use sleep over shutdown also.

Roughly 2 years or less. I purchased it the month before my wife and I got married. June 2015. MOF, everything is 2 years or less old. (FYI because I forgot to list that in the OP)

Interesting. I had read other similar posts online about standby. I thought I had disabled it completely. I will thoroughly check tonight.
