Somewhat modern design. Two transistor forward, but no PFC.

$55 for THAT? I guess it's because it's got Gigabyte all over it.. what a ripoff."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
That's an odd one. The part number 250-60HNN I can see on the PCB means it was probably designed for 250W, but there's no FSP of that model; instead there's a 250-60HHN (http://www.fsp-group.com.tw/english/...=176&proid=658), which is supposed to have a bottom-mounted 12cm fan. Perhaps a special part# for OEM, or maybe even a clone of the FSP?
The ratings are strange too since they match up with none of the FSP models and the 12V rails are far out of balance (one at 8A, one at 14?) A little surprising and disappointing to see a big manufacturer like Gigabyte overrating its PSUs.Comment

Re: the gutless, bloated, and fried power supply hall of shame
Looks like one of the "safety" Y caps shorted. Proper Y caps are supposed to go open when they fail. Or perhaps the coil arced over.
Yet another low end Solytech.Comment

Re: the gutless, bloated, and fried power supply hall of shame
Thermistor blew out, and filter choke burned up, 'cause switchers and/or primary rectifiers shorted. If you could believe its rating, the fuse is probably 8A. Mmmm... chip of the year.
Looks like that 'steel' was excess left over from the cheep 'n nasty scrapheaps disguised as cases. Gotta love the caps... Look! They used a TO-220 case rectifer for the 12v supply instead of two 3A FR diodes soldered to one of those stupid brackets...

Re: the gutless, bloated, and fried power supply hall of shame
Hey, it must be high grade - it's got a single United Chemicon capacitor. Makes up for all the other missing parts, doesn't it?
At least it's somewhat honestly rated at 180W, though. Powmax would label this 880W.Comment

Re: the gutless, bloated, and fried power supply hall of shame
L@hoo(.de) noname POS. came out of an Athlon64 3700+ (Socket 939) system..
i didn't even bother testing it.. opened it up and..well.. good thing i never tried to turn the system on with it
lahoo.de actually redirects to some kinda unknown company/shop named ONE.
the wiring on this is really pathetic.. 20AWG, with some 22AWG (!) thrown in the mix.. omg..
caps are all Canicon and SC/CS (the saturn logo) + 2 brown Su'scon on the secondary (which are actually the only non-bulging ones

Re: the gutless, bloated, and fried power supply hall of shame
LC-xxx model number, "2003" or "2002" PWM chip, phenolic board... it's another rebrand of the infamous L&C.
Schematic ("200W" but they probably just reuse the same one for the "300" and "350"):

(I'd trust this schematic the same as I'd trust that PSU, since they seem to have drawn it with the 5 and 3.3v connected together
)

Re: the gutless, bloated, and fried power supply hall of shame
Sorry, I just can't let a good thread like this die. I got my hands on another Sky 550W-P4 unit, and, as well as load testing it, I put it on the oscilloscope. It failed after about 10 seconds at 250W load (no explosions this time though. I don't know what went wrong, but I don't care either), and at 200W, the ripple was out of spec on the 5 and 3.3v rails.Attached Filesif you find these attachements useful please consider making a small donation to the site

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,... -
I was given this tv today. It was purchased just last month and only used for 3 weeks until recently when water leaked down the back and behind the cover. I removed the boards and WHOA 😲 did this thing get fried. Unfortunately the water got directly onto the backlights portion of the PSU. The board appears to be completely unrepairable, but I'm not certain about the backlights. I managed to get the probes of my tester into the slits of the plug and I DO get readings from both strings. I'm getting 26v from both. The PSU says LED Output is 167.4v however. Would this indicate that the backlights... -
While installing new SSD's in my new to me Dell 5520 laptop, I dropped a screw which sparked and fried a capacitor. Yes, I know I should have disconnecte the battery first Doh!😡. The laptop runs fine, but I want to replace the capacitor asap. I ordered and received the replacement (10uF, 25V 0603). Since I also managed to burn up one of the pads it was soldered to, my main question is whether it is okay to solder this capacitor on top of another capacitor (same size, same function in circuit). Specifically, PC4428 is bad and no way to easily solder to the board. I would like to solder it piggy...
