    Discussion Performance per litre - Round 4

    Do I get extra points for "personal heater" function? 😀 Temperature of the top plate, just above the GPU after Octane benchmark (GPU's backplate is touching the aluminium sheet):

    Discussion Performance per litre - Round 4

    Great competition! I'll join with my Ryzen 5 3500X (brand spanking used from ebay) and Zotac RTX 2070 Mini, MadMax-Frankenstein build 😀 Time to take you on, @guryhwa 🤣 Really glad with above - my build is a few points higher than someone else's with same CPU - means my open Frankenstein...

    Completed DIY "laptop" / portable PC

    I moved the 12v 600W UPS to a separate thread: https://smallformfactor.net/forum/threads/diy-12v-600w-ups-with-gxr-one-plug-in-psu.16628/ Any suggestions for improving the design welcomed

    Concept DIY 12v 600W UPS with GxR-ONE plug-in PSU

    I finally found a good wiring diagram for Daly 3s separate ports BMS: And laid out how everything should be connected: (capacitor on the photo is actually 1000uF, I added 2 more 10k uF later - voltage was dropping to 0 when switching between battery and PSU with too small capacitor) Looks...

    Concept DIY 12v 600W UPS with GxR-ONE plug-in PSU

    DISCLAIMER: this solution intentionally uses an appliance outside its official specification. Warranty may not cover any potential damage. As a part of my portable PC project I started tinkering with a battery solution for a PC. In the end my "lapdesk" doesn't have an integrated battery, but I...

    Completed DIY "laptop" / portable PC

    Last piece of the puzzle, 20cm ADT-Link Up-Angle Male HDMI to Down-Angle Male HDMI cable (A2-A3R model), finally came! Final, complete build as per parts list in the first posts. In the meantime I found Bingfu Dual Band WiFi 2.4GHz 5GHz 5.8GHz 6dBi MIMO RP-SMA Male Aerial Antenna (2-Pack) -...

    Discussion PSU with both 120VAC and 12~16VDC or 24VDC input

    I really like the idea :) If you mean using two 12v bricks because there are none powerful enough, I tried using 2x DELL DA-2 for a total of 440W and if PSUs are not designed to be master+slave, getting them to share the load is a proper pain. I modded a 750W server PSU in the end, but...

    Completed DIY "laptop" / portable PC

    Few quick updates from the list and some weekend tinkering: New hinges (HYC-TA model) are perfect! Fit like a glove and torque holds as set. tried liquid tape and copper tape on the exposed connectors on the PCIe riser (near the GPU connector) - didn't help with interference. 30cm RP-SMA RG316...

    Discussion Vertical, brickless APU ITX case where motherboard outputs at the top?

    I was looking for a very similar small case for a DIY laptop/portable PC and couldn't find any. Not sure if you mean the linear HDPLEX 300W - it's HUGE and really expensive. You could mount a HDPLEX 400W AC-DC with a "custom" jack output. ASRock's website doesn't list exact dimensions, so not...

    Completed DIY "laptop" / portable PC

    Nice, thanks for the links. They look good, a bit pricey, though. I played around with different keys and won't have to change the keyboard - luckily backslash works combined with W or S, A or D and Space at the same time. In British layout backslash key is between Z and Left Shift and on the MS...

    Completed DIY "laptop" / portable PC

    There are a few minor things I still want to do, but design is really unlikely to change from this final build: these hinges are not great. sometimes the adjustment screw catches when opening/closing and hinges can loosen a bit, but if you tighten the adjustment screw as much as possible and...

    Completed DIY "laptop" / portable PC

    Big milestone - 400 x 280mm plates came! Yesterday I finished the final build, took me pretty much the whole day to mark, drill, smooth, mount and connect everything! I'm hoping to not drill another hole at least for some time... Started with the usual - rounded the corners and blunted the...

    1000W max server PSU mod - 12v external brick

    I'm using the PSU like an external brick, with any animals or kids in the house I actually prefer a separate switch - I can leave the PSU connected to my PC but deactivate it separately. The humming when plugged into a socket reminds me to unplug it for extra safety, too. I was thinking about a...

    1000W max server PSU mod - 12v external brick

    Thanks. It doesn't turn off automatically, I have to flip the switch to deactivate it and/or unplug. Also, without any further mods the fan is turning even with the PSU deactivated but plugged in. It's a quiet hum, around 15-20dB, though

    Completed DIY "laptop" / portable PC

    Thanks :) If not for the damn WiFi interference it would have been an easy build, especially now with the SFX PSU. Including all of the 400x280 plates and the USB-C monitor when folded, total volume is a bit less than 9 litres (40x28x8). I marked out vent holes on both 425x300 aluminium plates...
