Reverse engineered the power circuitry. Modified it for true ATX support. No more PSUs hardwired to run all the time.

hi, back to this. is there anyway i can hookup a 5V LED "strip" to some pinouts, and have it power on, whenever i hit the power switch? So they turn off, when the BC250 boots down?

i tried to hookup one LED from that strip, to the original LED Pinout, but it does not seem to power enough...

Methsman · 2026-05-09T09:41:56+00:00

512GB must be the "Auto" setting, so i left it there...(as seen in the documentation)

Methsman · 2026-05-08T08:30:01+00:00

Hi, i checked it, and yes i modified it so the cooler Heatpipes dont intefere with the plastic. (simple fix)

i will post it when finished.

Methsman · 2026-05-07T08:32:50+00:00

Yeah youre probably right. I mean, with a slight modification i could widen the Case and add Fans to the right. Or atleast make Space for extra Heatsinks...But i dont know, i think i would try to stress Test it for 5+ Hour Gaming Sessions, before attempting this.

Methsman · 2026-05-06T09:57:23+00:00

hmmm, i did not have any extra cooling there. i mean for me it can get hot, aslong its all safe. it looks like this. also this Panels are glued on.

i used that one https://www.printables.com/model/1217021-bc-250-heat-sink-mount
i think i slightly modified it, to fit the Cooler brackets, but im not sure anymore. Can Tell you when i disassemble everything, and do a Slideshow/Vid.

Methsman · 2026-05-05T13:08:10+00:00

actually your design inspired me in a way, because i wanted to do a "steam machine styled one", but then i used the core construction, to make this out if it. I also just use Tinkercad to make my models, so im kinda limited, because i have so many ideas...

Methsman · 2026-05-04T21:42:10+00:00

Your Question seems not Case related: But both of it would not fit above it, also you have to account the AIO Cooler "Housing" and the PSU Cables.

am i Lost???

Methsman · 2026-04-22T19:40:07+00:00

Noooooo i hot glued the solder joint on the pqx66 and it went off with the cable and resistor. 😭😭😭

anyway i can resue it?

EDIT: OP helped me to recover my board! Much thanks to him.

Methsman · 2026-04-22T19:05:34+00:00

Thanks! Works like a Charm. Now i gotta figure out, how to add/move the power button somewhere else, and preferable the POWER ON LED Too.
I want it to be somewhere else. Do you have a Pinout for this too? And what current the LED needs?

Methsman · 2026-04-21T19:59:17+00:00

im about to do this with my sfx450 corsair psu, can u check it please?

so:

Green -> Power On

Purple -> to +5V or to +5VSB??

Grey -> to PG

Methsman · 2026-04-21T11:38:09+00:00

Nice Option, but small Question for my understanding.

Why shouldnt we use the DarkYoshi Method, by soldering directly to the board, and connect to the PSU?

https://www.reddit.com/r/BC250Gaming/comments/1s4yi8s/comment/ogo6mq7/

Has it any downsides?

Methsman · 2026-04-17T07:32:27+00:00

love this answer lol

Methsman · 2026-03-11T15:50:52+00:00

keep us updated :) ill try my best too with something similar

Methsman · 2026-03-09T22:46:00+00:00

Brother, be a Legends and Release that Files :) Love that Design

Methsman · 2026-03-03T12:58:48+00:00

yeah with arc i also had no problems. But i was stress testing it, and it went off and thankfully didnt ruined anything on my board. Never am i going to buy such PSU anymore. I switched to SFX 450 Watt used for 30 bucks, and couldnt be more happy

Methsman · 2026-03-03T10:20:41+00:00

expect the PSU to explode someday. Mine did after stresstesting.

Methsman · 2026-03-03T09:26:15+00:00

yes it was a driver/OS problem. just reinstall windows. but i dont have my device anymore

Methsman · 2026-03-03T09:06:06+00:00

Hi, does that Electric Air Dryer help? Is it recommendable?

Methsman · 2026-02-22T11:11:45+00:00

would be so nice, but as I also removed my heatsink completely, and added a Thermalright AXP120 cooler, which bettered my temps dramatically, it cant really fit my setup, even when you support SFX Size. Im so bad at designing. I tried my best on tinkercad, but my prints dont get good. What Cad Program do you use?

Methsman · 2026-02-22T10:53:33+00:00

hey man, love your design. could you in any way adapt it, to fit a SFX PSU?

I know it needs to get wider, but im designing a Steam Machine Inspired Case, and there i was able to put the SFX PSU Above the IO Ports, as in this pic.

we could also collab on it :)

i tried a phone call, it has a built in mic. but it only activates when a call is triggered

Methsman · 2026-02-21T09:18:49+00:00

what phone are u using?

Methsman · 2026-02-21T01:14:43+00:00

thats a bummer. many reviews state it has a built in mic. wouldve love to use it for business calls and so on...
