My boss has been using this brand of PSU called Aywun. We usually use the A1-5000 (500W) model. Has anyone here heard of them? I took the cover of one and they don't look too bad at all. The heatsinks are a good size, as are the transformers. There's a rectifier (not 4 diodes). No missing/jumpered parts on the transient filtering. From memory the primaries were 680uF. The secondaries are "BH" branded. I'll see if I can get some pics of one once I get over this flu and get back to work.

I know BH caps are bad. I can't remember the brand of fan. probably some off-brand.Originally posted by ratdude747
I realise they are probably junk as they come from the factory. I think they may be keepers, however, if the caps and fan were replaced.I love putting bad caps and flat batteries in fire and watching them explode!!

From the one that I could see inside shots of (a Micro ATX unit,) it was a codegen.

Re: Aywun PSUs. Anyone here heard of them?
or deer, where you pay $ and get the most gutless L&C ever, pay $$ and get a lackluster but mod-able unit, or pay $$$ and get a decent unit that only needs better caps; the rest is all there and well.Originally posted by 370forlife
I remember a picture of a "vogue" branded deer AT unit... it so little caps for filtering on the secondary that it even blows my mind how it ever ran in the first place...
wait- here it is!
Vogue (rebadged Deer) 230W AT unit, manufactured July 2000. Viva primary caps; the rest Rulycon (my first real sighting of this brand!) and one CapXon.
that was bad.
good:
deer unit, found in a computer that was still running despite the fact that all of the vrm caps were blown

Re: Aywun PSUs. Anyone here heard of them?
Solytech owns deer now. It's now called the "deer group" consisting of Deer computer, Solytech Enterprises, and Apex.
This is what you get from solytech if you pay a bit more:
It's even 80plus silver with teapo secondaries.Attached FilesComment

I'm thinking when solytech bought deer they fired all their old engineers, or kicked them in the ass.

Picturres
OK I took one home today. Here are some inside pictures. The rectifier is a 4A. Thie two smaller transformers look a bit smaller in this unit that they did on the other one I opened, but the main transformer is still more beefy than what I see on really cheap no-name PSUs. They usually sell for around $40 AUD. There's also an A1-3000 (420W) and an A1-2000 (320W).
What do you guys think? A Keeper after a re-cap or throwaway junk? ALso, What wattage do you think it could manage?Attached FilesLast edited by c_hegge; 06-23-2010, 03:05 AM.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: Aywun PSUs. Anyone here heard of them?
The heatsinks and output rectifiers (particularly the +12V one), as well as the 200V input capacitors are a bit small for this wattage.
I also saw a 450W power supply (new) for only AU$30! - it was not going to be used anywhere near its maximum output, and the heatsinks were a bit small.
That goes to show you only get what you pay for...My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

Re: Aywun PSUs. Anyone here heard of them?
reminds me of the Yuelin-based "powork"..
http://www.jonnyguru.com/modules.php...Story3&reid=71
i'd say it's a ~ 300W (maybe 350W) keeper with new caps.
seems to be a 3.3/5V heavy ATX 1.3 unit with 12V being overrated to calculate up to 500W on the label (imho)
edit:
knowing what's on the label and how it looks like inside, but not knowing the specs of the silicon actually in there, i made a (messy) chart..

Re: Aywun PSUs. Anyone here heard of them?
It looks like a keerda, same people behind logisys. Really dosen't look that bad, I see two diode packs on the 12v rail which is favorable. Heatsinks/primary switchers/transformer looks beefy enough for a 300-350W load.Comment

Re: Aywun PSUs. Anyone here heard of them?
I replaced the caps with the following
1x 1000uF 10v -> 1000uF 6.3v NCC KZE (salvaged from dead motherboard)
4x 1000uF 16v -> 1000uF 16v Sanyo WF (salvaged from dead motherboard)
2x 470uF 16v -> 470uF 16v Panny FM (new)
1x 3300uF 6.3v -> 3300uF 6.3v Panny FJ (new)
2x 2200uF 16v -> 2200uF 16v Panny FC (new)
I have also added a fan controller salvaged from a dead PSU.Attached FilesI love putting bad caps and flat batteries in fire and watching them explode!!

Hi Folks,
Just wanted to clear up a misunderstanding of mine (or what I expect is one). Isn't the 12V rail from the 24 pin, EPS and PCIE separated? IE if I put a power resistor on the ATX 12V pin that is not going to load, thus tell me if the EPS or PCIE rails are fine?
I was recently watching ArIs from Hardware Busters video on how to properly test ATX PSUs without using 5 figure Croma substations.
The PCB adapter he used breaks out the 12, 5 and 3.3V pins from the 24 pin and gives you banana plugs to connect to. That is a bit useless is it not? Aren't... -
Hi,
A colleague gave me an apparently ill CORSAIR CX600.
He told me that he heard a banging noise, and smelt the magic smoke.
After tearing down the PSU, no burnt component, everything seems OK, but the PSU often refuses to stay ON. When shorting PS_ON to GND, the fan spins a bit a finally stops. No output voltages.
I tried to treat some apparently bad solder joins and finally it seems to work OK... on the 12V and 5V rails!
It's another story on the 3.3V rail...

Hello again, this might be a bit of a far-fetched question, but is it possible to modify a 36v and a 48v power supplies to output 12v? Both power supplies appear to use the same topology, they both also have a dedicated 12v winding wired to the control chips, meaning that as soon as i change it so the main output is 12v, then the dedicated windings will not be able to output 12v, meaning it will not start up. However, if i were to then take the main output and tie it to where the dedicated 12v output would go, then it should be able to run fine?
Anyway here is a quick overview of... -
I have a couple of these PSUs that have the exact same issue on both of them. I find it odd that they both exhibit the same Symptoms.
When plugged into the PC, the PSUs are able to power the LEDs inside the motherboard (the standby 5v circuit I suppose?) But as soon as the power button is hit, the PSU powers on for a split second, then there is a (relay?) click and the PSU shuts off. Hitting power does nothing after unless the power is removed and then turned on again.
I have a PSU tester which has the same results. As soon as the tester plugs in, it powers on for... -
Hi All,
Before replacing what I know to be bad even with my novice experience. What I have checked at the moment is the fuse and the obvious burnt capacitor. I haven't bought any replacement parts yet.
I still have no idea how this happened but could just be plain old turned bad. What other stuff should I consider buying as replacement? thanks in advance.
Edit: I saw that a replacement board can be had for about $50. I would rather attempt to fix before just replacement the board.
