Log An STX enclosure with a super short 1660 Super

[gwk]

I built an STX enclosure that supports a super short GPU such as HP OEM 1660 Super in my case.
Its limited to PCIe Gen 3 x4 so it's not super practical. This PC is comparable to my 1660-Ti laptop,
but waaaay quieter, and the core components were second hand parts from eBay:

HP OEM 1660 Super
ASUS Q170S1
i5-6700T


Hopefully someday soon there will be a short-PCB GPU that supports PCIE 4.0

Still need to redo one of the panels because I screwed up the rear IO cutout. Also using a modded Pico PSU in order to switch 12v to the GPU when the system turns on. Using a transistor, the fan header controls the Pico's PSON signal. I hate how annoying it is to control 12V to a GPU in a non-ATX system like this.

Does seem like it's a hassle!! Also, your STX board didn't have an optional internal 12V power-in? That would've been handy...

Nope, and I looked! this ASUS board must have been for a kiosk or something cause its got pins all over the place for LCD, Backlight, etc.

Hmm... I think I would've tried to solder wires directly to the solder points of the DC connector jack, ha! But yeah, not a super consume-friendly board I assume!!

I still might do that, but then I would probably want to cover the STX DC jack because then it would be a voltage source and could be a shock hazard.

Desolder it, or fill it with hot glue, haha In any case, good luck with the rest of your improvements, I'll keep an eye on your thread

You can sync the GPU to the fan header with a smaller relay if you want, it might be marginally smaller than a Pico psu

I got my 3mm Matte panels from Ponoko! They've got way more acrylic than SendCutSend

I'm not gonna get matching fans cause this build is dumb

Do you have a link to a part?
I would appreciate it. We were going back and forth on JHack Discord about this a few weeks ago.

There are smaller ones but thats the basic idea

Hmm, the 1660 Super is about 125W so that would be cutting it close.. Although I do prefer to undervolt.
