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
btw i did save some parts before i tossed it.
could have fixed it if i wanted to wait a month for the part to come slow boat but i have better things to do besides polishing turds.
because that is what all leadman/coming data/deer/whatever they go by this week are.shitboxes.Comment

Re: the gutless, bloated, and fried power supply hall of shame
I don't blame you. What did you decide to keep out of it? Usually Leadman uses decent wires because they want the exterior to look good so that it will sell...Comment

The cutout in the heatsink around the 5VSB rectifier diode is nice.

Here's a Solid Gear SDGR-750E (Leadman LP-8869E) from a friend's computer. Secondary caps are Chengx, no idea about the others. Looks like maybe a 300W to me.Attached FilesComment

Re: the gutless, bloated, and fried power supply hall of shame
It's the same thing as the Inland. Based on the model, this one is probably rated for 750W.Comment

Re: the gutless, bloated, and fried power supply hall of shame
Delta Serverpower 450W EX. (CAA-450BT A). Was browsing the Web on my Ivy Bridge system when there was a loud pop from the power supply and the system shut down. I took it apart but there is no sign of damage. I think only the fuse blew. I would like to identify the problem that caused the fuse to blow. Any ideas? It has only been in use for less than two years.Attached FilesComment

GTR Type-R 400W. Thoughts welcome. All the caps on the secondary are Cheng brand 10V 1000uF, no pi filter coils.Attached FilesComment

Re: the gutless, bloated, and fried power supply hall of shame
250W max with ripple barely in specs is the best you could get from it.Comment

Re: the gutless, bloated, and fried power supply hall of shame
Forgot to post the power ratings. Is it safe to use it in a 200W system? Eg. Pentium Dual Core (E5400, 45nm), integrated graphics, 2 sticks of DDR2 RAM, 1x SATA 7200rpm hard drive, 1x DVD-RW drive and a 12cm case fan?Attached FilesComment

Re: the gutless, bloated, and fried power supply hall of shame
It is unsafe to use it anywhere unless you put some input filtering, coils on the secondary and change the caps.Comment

Re: the gutless, bloated, and fried power supply hall of shame
Agreed. As it stands, I wouldn't allow that within a mile of any of my PCs.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
OK, so I should add pi filter coils on the secondary and change all the caps. Do I need pi filter coils of any particular specification, or can I just rip them from another power supply? Also, on the transient filter, what do I need to add? It appears to have one coil, two X caps and two Y caps in place. Thank you for your advice.Comment

Re: the gutless, bloated, and fried power supply hall of shame
I suspect you will need to calculate the right value for the pi coils rather than just put anything in, if you want the PSU to operate correctly and stable. How you would do that though I have no idea."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

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...
