Re: Power supply build quality pictorial. part 2
Yuelin aren't the worst units I have seen. I would put them below sunpro, though.

Re: Paxville or Bust! The Supermicro X6DA8 Project
Ahh the X6DAL board. I had an X6DAL-G when I was in highschool as my main computer. I'm not sure what happened to that machine. I think it fell victim to my Dad's murderous computer recycling after I moved out. Sorry, that just made me really nostalgic.Last edited by 370forlife; 05-15-2018, 07:46 AM.

Re: Gigabyte GA-586DX Retro Goodness
I've been getting really into retro systems lately. The fact that it is ATX is way cool. I have been trying to hunt down a dual socket 7 AT board at a reasonable price.

Re: Power supply build quality pictorial. part 2
The messy but complete design and choice of dodgy components makes me think it is an old Superflower design....Last edited by 370forlife; 04-08-2016, 08:50 AM.

Re: HEC Orion HP585D
Weird, I come back after a while and see one of my old threads resurrected the same day.

Re: did i pull the foil tube out?
If it is the power supply, chances are it is single layer. You most likely just have a blob of solder on the leg of the capacitor shaped like the hole. A picture would be helpful.

Re: Power supply build quality pictorial. part 2
Its not even that lucky. Its a half-bridge unit. If designed well, a half bridge unit can deliver the advertised wattage no problem. 13009's are not sufficient in this case, and this unit is not a stellar design....Last edited by 370forlife; 10-14-2014, 07:02 PM.

Re: Advanced electronics fx 500 lpz12-50
This is most likely a KMEX, as this is a copy of an old (but good) ATNG platform that KMEX is known to make a copy of:

Re: smps transformer
If the power supply is like a computer SMPS, there is kind of a second, smaller power supply that runs the 5V stand by circuit. Its generally a very simple two transistor setup on a cheaper unit, or a discrete IC, that has a low current rating. The 5V stand by circuit has its own, small, transformer.

Re: rectification in smps
Many simple power supplies do simply rectify the input AC voltage into a DC voltage, then run it through a transformer to step it down to the correct DC voltage. The problem with this is you need a huge power supply to get a small amount of current and they cannot regulate themselves. What this means is that a 12V supply would probably put out 16V with no load, and under full load may only put out 10V or 11V.
DC transformers that can handle the same amount of current as an AC transformer are substantially bigger. We can solve this with an...

Re: Chip of the year data: 2002, 2003, 2005, 2012
Hi everell, good to see you are still alive.
I believe those chips marked with a year are used solely in power supplies manufactured by Deer/Solytech. I don't know if they are a proprietary design by them or simply a commercial chip that they put their name on.
