Some Background: 

Even though I have had an EPOWER V for quite a while I found myself using the older EPOWER classified instead. Having Software voltage Control is a must have feature for me since I find the buttons very awkward to use when the EPOWER is mounted on a GPU.

When the EPOWER V was released voltage Control over USB-C was promised, but since that still doesn’t exist, I started poking to try and see if I could build a solution myself. To my surprise I found that there is voltage control already implemented.

I have no idea why this is hidden, and it doesn’t work over USB, but it does solve my problem of reaching around my card to try and change voltages. I assume I’m not the only one with this problem, so I wrote a guide in hopes that other people find it useful.

I also still hope that EVGA releases a solution that works over USB and maybe exposes even more settings.

Awesome!
