I wouldn't take that risk - it's two separate transformers/ power rails... there is no benefit in having both connected.

Thant‘s he standby power, for the system to work as intended in the ATX spec it needs to be present permanently. If you provide this through the pico, you only get it when the 12v rail is active and feeds the pico, and in its absence, you cannot power down/ up the PSU through the motherboard. In...

Here's the score for my 2023 project - still tweaking a few things, I think I may be able to take this a bit further with some CPU undervolting, but for now I'm rather happy with where this lands: CPU R9 7950X3D GPU 4090 FE Case Skyreach 4 Mini Volume 5.0l* Cinebench R23 Multi-Core...

A brief update on performance - after retraining the memory (I had skipped this in the bios to economise on boot times...) I am now beyond the 1M mark in the PPL round 4 score... with the vanilla bezel coming with the case. Not as pretty as my own design, but I consider this a track suit for...

petricor submitted a new resource: 4090FE PCB Model with SMDs - 4090FE PCB Model incl SMDs Read more about this resource...

A 4090FE stripped to the bones, as featured in this build, following a community request and hence in Fusion360 format only... the app is a free download so anyone should be able to convert it as required. Cannot really take credit for this model... habe patched it together from various...

Actually - checking my own test logs, I have been homing in on 80%, not 85% for the GPU- interestingly, this gives me higher boost clocks. Bottom line, I'm pretty certain that it draws a little less than my previous build: Nominally, the 4090FE pulls 100W more than the 3090FE (450 vs 350W) - but...

Well-spotted - and a fair point. Taking the dimensions, it adds 0.26l to the bounding box so with that bezel it's 5.26l- gets the high score in my table above to 933k. In this configuration I suspect the bezel only marginally contributes to the cooling though. I have originally designed the...

All things must come to an end - and here that means some snags, tweaking some settings, and a few thoughts on performance: A few weeks into running the build, I can confirm that everything runs (surprisingly) stable - clearly, it has one giant thermal bottleneck which is the 140mm rad - with...

Hey @stanleyguan, no, not that I would have noted (I may have gotten lucky with the anodisation preventing the worst), but now that you say it: This has indeed been a mistake. Next time I'd machine it in copper with a nickel coat, or in a black acetal...

Nice one. I believe that that's as small as it gets without soldering onto the PSU directly... have you measured how far it projects beyond the front edge of the PCB? Pretty sure it wouldn't fit my build, but it looks like something I may want to plan around in the future!

With everything seemingly running, it's time to package things: The spaghetti monster in the top right corner (my already pre-shrunken aqua computer) needs to lose some more volume... ...and fit into that corner right of the pump at the rear of the case - that's where I'm pointing at here...

NIce work! Will definitely go for copper-nickel for my next one... your fabrication outfit appears to make that feasible - I understand you paid less for your metal part than I did for my plexi cover! What did you use for your hose connections? Threaded inserts? Gets me thinking: A real...

It looks like this project is slowly starting to come together! Before I get to fill it, I need to tackle this guy once again though. It turns out that the Pico PSU is a tad too wide after soldering on additional power wires: You can see that it creates a wedge-shaped gap between the PSU and...

Forgot that indeed - came from a giant book store, link here!
