Recently I got into contact with the supplier of that 500W power supply that I've been servicing earlier, as I lost my pictures of the disassembly process with that craptacular Nexus 6P (didn't back them up.. terrible sysadmin, am I not?) and wanted to get the circuit diagrams of this thing in order to repair it. Sales girl wanted to give it to me but she'd have to ask the factory people.. and of course those people denied. As if I wanted to use this for anything but to repair my own bloody unit.. pieces of shit.

So I started considering buying a second one, in order to repair my current supply that I've already spent half a week on to document its components, desolder it, clean it up and resolder it (and replace some resistors here and there with better ones from my own assortment). And the project had to be paused because I lost the stupid pictures and couldn't for the love of God figure out how there's supposed to be a jumper near BD2.

Just now going through my notifs..
"Someone ++'d your rant!"
*clicks notif*
A rant that I completely forgot about.. https://devrant.com/rants/1757297. It's a perfect picture of the supposed jumper near BD2 that I was scratching my head about for so long. Turns out that it's just a dupe of the LF2 lines that I erroneously wrote down twice. DevRant, it's good for more than just venting, haha! Time to restore from a cloud backup XD

@joeperri95 Haha, that'd be amazing! XD

Luckily, you posted that after the drunk-deletion. :p

@rsync AliExpress is the cheapest by far, but it's kind of a gamble when it comes to quality.. bought some 180W supply from there (12V 15A), a 200W supply (24V 8.3A) and both of those are good. They're clean, serve the purpose etc. Not sure about EMC though.. switching supplies are known to be noisy when it comes to electromagnetic radiation. Perhaps the grounded metal case contains that. This 500W (50V 10A) supply though, I kinda regret purchasing that one. Too much work went into that one, just to remove all the flux and replace some of the components. I just got it working again though 😁

As far as brands go, well AliExpress doesn't have brands really. I usually just go for the cheapest out there. Choosing a power supply like this is mostly a matter of choosing the voltage and the current it's going to have to deliver. That 500W supply will be powering 2 DPS5005 lab bench power supplies, which are 250W each and preferably take about 53V on their input. Hence I chose a 50V 10A supply for the AC-DC conversion part.

For something hassle-free and beginner-friendly, ElectroBOOM is using an AC-DC lab bench power supply from Circuit Specialists. It's got less pizazz for the price than this DIY contraption (mine's 500W that's CV- and CC-controllable for about €60, whereas a complete unit from Circuit Specialists for that price would be only 150W), but it's a complete solution whereas my build is mostly DIY and takes quite a bit of construction time.
