Those were fairly common here a few years ago, but were branded Rexpower or Maxpower.I love putting bad caps and flat batteries in fire and watching them explode!!

Hahaha. Love the replies I just realized how small that 5VSB transformer is, I imagine it would struggle over 1.25A

200W, OK; 250W, pushing it; 300W, dull red glow; 500W, brief incendiary event.
I wonder if use of unapproved Y caps like this POS was behind the death of that Chinese person who had an after-market iPhone charger.PeteS in CA

Same picture as in the badcaps photo gallery
They have the Fairchild F, with no dash through the F and they just look cheap. I will post a picture of them later tonight
"500W, brief incendiary event."
It's possible that's what happened. How do they get away with using the unapproved Y caps?Comment

Re: the gutless, bloated, and fried power supply hall of shame
Get away with using unapproved caps? Maybe the agency marks are bogus. If real, the samples provided the agencies for testing had the right parts, and then cheaper unapproved parts usd in production. How much risk is there for a fly-by-night mfr?PeteS in CA

Re: the gutless, bloated, and fried power supply hall of shame
What agencies? Nobody officialy cares! You can just stick CE on anything and sell in Europe. Well, you actually probably even do not need to do that, nobody checks even the bloody CE mark…
Not that I am calling anybody doing it! Customer is the one responsible, all the socialists can go f*ck themselvs with restrictions and regulations and controls.

Re: the gutless, bloated, and fried power supply hall of shame
Can you confirm this is a bad capacitor?

Re: the gutless, bloated, and fried power supply hall of shame
If it was fine prior to power off, I would suspect an issue with a startup circuit. Since the startup is only needed at.. startup... constantly running the thing will not show an issue until you power it off and try to turn it on again.
Those capacitors *look* fine, not bulging or leaking, BUT Su'scon is nothing special."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: the gutless, bloated, and fried power supply hall of shame
hmmm can I get a second confirming that its just glue?
That sucks as it is the only obvious thing I can see.
Does anyone have someone in New York city (I'm in Brooklyn heights) that they can recommend to check it out?
I'm comfortable pulling the board and soldering replacement capacitors but out of my league to trouble shoot a circuit.
I tested the batteries (52v at terminal and 12v on each individual battery) so don't think that's the issue.Comment

Re: the gutless, bloated, and fried power supply hall of shame
The glue gets conductive, this was never supposed to be used in electronics so if it is already brown somewhere, clean it out. Check all fuses and power semiconductors.

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)
Laptop is a Asus G15 Advantage Edition 2021 Laptop Ryzen 9 5980HX - 6800M...
