Re: the gutless, bloated, and fried power supply hall of shame
I know, hence the reason I said most and not all. I had an A7V600-X years ago, which had no ATX12V connector. The problem was that the main 20 pin ATX connector would get very hot and it eventually discoloured the 5V pins on the conenctor - evidently, the CPU was pulling too much from the 5V rail. Typical ASUS and their cheaped out peice of junk boards...I love putting bad caps and flat batteries in fire and watching them explode!!

Winsis SKY-560 ATX
So this thing came in a case. It's actually better than I thought it would be. Still really overrated. It uses TO-220 13009's, 6A bridge, "560uF" input caps. The transformer looks decent so it has potential. The 5V uses 30A schottky, 3.3V uses 20A schottky, and 12V uses a 20A ultra fast. There is a second spot for another rectifier at least. And....it needs one bad. I put this in a system with a Pentium D 950, and a Radeon HD 4670. With both at full load, the 12V dropped to 11.59V which made me think it was getting pushed to the max. However, at idle, the 12V only went up to 11.82V. It was pulling 265W AC from the wall when testing. All I've done so far was recap it. The fan was well oiled, and was quiet even after revving up. Not sure who the OEM is. Soldering looks good for such a low end unit though.
Need to find some MOV's for it too and it'd be a nice little unit for a Core 2 and a low end video card
Edit: Okay, I forgot to mention that I also replaced the non safety approved Y caps, and replaced those film caps with real X capsAttached FilesLast edited by Pentium4; 01-07-2015, 10:47 PM.Comment

Re: the gutless, bloated, and fried power supply hall of shame
Okay, I upgraded the rectifier last night. I was gonna throw on two 30A schottky packs but decided one was enough for this PSU. I replaced the SFR20S20T ( ) with an MBR30H100CT ( https://cdn.badcaps-static.com/pdfs/...4735f13e3b.pdf ) and the 12V is so much stronger and more stable......with enough on the 5V.
I stupidly tested it out with the new rectifier on a brand new Haswell system, which is probably 97% 12V based. Intel Core i5 4670, x4 DDR3 sticks, GTX 650, Intel 240GB SSD, DVD drive. Under a 125W AC load, the 12V was oscillating between 11.42V and 11.92V!
When I put it in an older machine with more 5V, AMD quad core, x2 DDR3 sticks, HD 5450, x2 spinning hard drives, DVD drive. When pulling 120W AC doing the same test, the 12V only bounces between 12.08V and 12.16V. What a difference! It seems to be running more cool now thanks to the lower forward voltage loss of the shottkyComment

Re: the gutless, bloated, and fried power supply hall of shame
And this just goes to show you that you don't need a 500W+ power supply for a modern system with a high end CPU.
Where did you buy those shottkies? Mouser, Digikey? Or free samples?
I'd love to go to one of those manufacturers' factories and take a scoop of their reject high-power rectifiers. I'm sure at least half of them would be fine. Would be fun to upgrade my older PSUs that don't have a 4-pin 12V CPU connector.Comment

Re: the gutless, bloated, and fried power supply hall of shame
That's right and I was wrong, it's actually a Phenom II x6 1035T.
I got them from Digi-Key. Pretty good price too, I got 25 of these: http://www.digikey.com/product-detai...GOS-ND/1477174Where did you buy those shottkies? Mouser, Digikey? Or free samples?
Probably. That would be pretty neat. You mean to say that you have a bunch of AT power supplies?I'd love to go to one of those manufacturers' factories and take a scoop of their reject high-power rectifiers.

Re: the gutless, bloated, and fried power supply hall of shame
While they certainly can fail, the only cases where I've seen failed Teapos and OSTs in "good" (Seasonic, Hi-Pro, Delta, etc.) power supplies were in hot areas on high-hours units (generally pulls from corporate desktops that had been running 5 years 24/7).Comment

Re: the gutless, bloated, and fried power supply hall of shame
Datecode of those transformers say that unit was made in the middle of 2007.
So it's about seven and a half years old - that's not that bad, is it?!Comment

Re: the gutless, bloated, and fried power supply hall of shame
Datecode of the capacitors and board itself (2009/25) says 2nd half of 2009. They used 2 years old crapacitors, it was probably working less than 5 years.Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts

Re: the gutless, bloated, and fried power supply hall of shame
OST RLX are generally quite unreliable. RLS (black/gold, often found in PSUs) usually do better.
Also, are you sure that OST RLX was original to the PSU? The fact that it is 2 years newer and the fact that it is RLX makes me suspicious. Reason being is that RLX is uncommon in PSUs (they are close to specs to HM and are usually used in motherboards).Comment

Re: the gutless, bloated, and fried power supply hall of shame
what do you know about RLP?Comment

Re: the gutless, bloated, and fried power supply hall of shame
Only had one encounter in a Shuttle computer, and almost all of them were bulged - some even on non-stressful rails and away from heat sources. Just based on that, I would say no better than RLX. But I could be wrong of course - one experience is not enough to conclude, IMO.Comment

Re: the gutless, bloated, and fried power supply hall of shame
That RLX is indeed original. I think that the PSU was made in 09 and that the transformer is made earlier. The Seasonic built Antec Earthwatts PSUs always used OST RLX in that position. Interestingly, though, I've never seen that particular cap fail before. The only one I've seen fail on the EA-380 and EA-500 is a larger RLS on the 12V output.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: the gutless, bloated, and fried power supply hall of shame
Yep, some parts were made earlier, the OST in question is 2007, the rest was 2009 ad assembled who knows when, I cannot read much from the label/serial number. It was ditched last year when the original computer was wrote off (partially because of problems with turning on), the guy who got the computer than for parts said he was not able to turn it on at all by the time he got it. That's when I got it for repair which was done this month.Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts

Re: the gutless, bloated, and fried power supply hall of shame
I think that actually is a 2007 board, it looks like a Japanese style date code on the PCB with the year hidden under that glue (2007/09/25). The ICs are also from 2007 (U101 is dated 0725).Comment

Re: the gutless, bloated, and fried power supply hall of shame
EMKO JS-300B HAZARDOUS AREA yeah baby around it when it's runnig
It actually even has full input filter with genuine Y caps and varistors+thermistor! And the transformer is not too bad. And bridge rectifier RS405. Other than that, 470uF VIVA caps, 2SC4106 switchers (may be good too), SBL1040CT for +3,3 V, FG1004 for +12 V and SB1540 for +5 V. Oh yeah 30 A my ass
Some of the secondary caps are bloated, every single cap biger than D6,3 on the AOpen motherboard it was powering was bad. And it was only with ceramic Athlon 1000 (Thunderbird) and Manli TNT2 M64. HDD has Spin retry count of 18 with big red FAILED, but runs just OK, possibly it was unable to start due to poor power from this unit.If I had nothing to do than I may renovate this, but it's waste of time with all those Fortron units I have here which are 10times better after recap.
Note that small cap with K-shaped vent under the input connector. Yes, it is our beloved Rulycon

Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
A "nice" YoungYear unit? - Badcaps
The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish.... -
Introducing... the POS-124Z which really is a POS:
Yep it's a POS allright.
I tried powering it up. It's a KILLER - not fried, but sure will fry things! I got 21V out of it unloaded according to my DMM!
I tried 21W load (car lamp) - got 16V, which is really pushing that lamp.
Then I tried a 50W load (car headlight) - got 13.2V. Not too bad but this is with the heavy load...except the circuit breaker kept tripping.
So I had to take a peek:
EIEW. Looks like a Darlington emitter follower + Zener device. Heatsinking?... -
Hi,
I'm learning electronics(already have some basics) by fixing a FH52M LA-J891P rev1B. It come from an acer nitro 5. The charger was defaulting upon pluging. The 19V rail resistance is 0ohm (I believe that caps screw my measurement). When i inject 5A, I get a rail tension of 1.3V, and 0.8V vcccore.
Except the cpu, I cant feel anything getting warmer.
I believe that it is normal, because the cpu is "eating" half the power I'm imputing.
I dont know if the cpu is fried, because I did not remove the big capacitor on vcccore.
I believe that if the cpu was fried,... -
While our PSU hall of shame thread is fun I thought It'd be fun to have a ripple hall of shame thread too
I'll go first out, it's an industrial PSU that offers +15v -15v -5v +5v rails.
However it has been mounted on a frame with DC/DC converters for producing +12v and -12v as well.
The caps for this have gone a bit high ESR
The measured ripple is around 1700mV, or 1.7v!
After recapping the ripple is gone, also note that the scale on the scope is 50mV/div instead of 500mV per div in this shot

Hello!
Looks like I fried something when my EDP cable got squeezed on the hinge. I replaced the cable but still no display. Laptop works fine with external monitor connected through HDMI and Display Port-USB C port. I took it apart and I see a burnt component. Can anyone help me identify what this component is? I tried to use schematics for another G15 but it does not match on the amount of pins and size. I attached pictures. The component has a label on it - (21A29)
