--- Quote from: bd139 on June 12, 2020, 04:16:36 pm ---That's a bummer. There's enough fragmentation so I agree. I built my first desktop for about 10 years recently and was annoyed to find out that I still had to frig around with LED and power switch wiring like I did in the mid 1990s. Perhaps they can consolidate all that first. --- End quote --- yes I just upgraded a computer with a x570 MB and had to faf about with the front panel connectors, granted it was a lot simpler this time, as the connectors had the polarity marked on them and it was only 5 of them, so fairly easy and painless :) it just worked. but thats part of the case design. |

Yeah mine worked first time as well which surprised me. I did see a picture the other day where the cable had two reset button connectors on it and no LED though :-DD |

Anything wrong with that? It's the fun part of building your own PC. ^-^ |

I have long wished that all the devices in my house simply ran off DC. you could have a stack of 18650s in there with a BMS and have your own sweet sensual UPS for a fraction of the cost of those horrible big nasty UPSes that just include those disgusting alternators with their jaggedy excuses for sine waves. --- End quote --- A number of mini-ITX motherboards can already run off DC without any additional module. Of course don't expect high performance from this, but I've built a Linux box that is on my LAN and that I use for Linux dev tasks, based on a thin mini ITX MB (ASUS) with a Core i7 4790T and 16GB RAM. Not ridiculous. Runs off a DC adapter and is fully passively cooled (the case is made for this - it gets a bit hot under load, but never failed.) |

There are a few "canned" desktops which can do that as well. Lenovo M600's run off a 19V DC thinkpad charger I'm using one as a media centre at the moment. Fanless Celeron that runs LibreElec + Kodi. Nice little machines. Also make handy Linux utility boxes as they run headless. |
