Wanna see a power supply with GOOD Fujhyyu caps??

Crap is crap, no matter how much you gold plate it.

Flat today, blown tomorrow.

my thought exactly. it will blow up, it hasn't yet, but it will. and when it does, it might take the rest of the system with it to computer heaven... 18v on the 5vsb is not good...

Yeah. LPXXXX part numbers are made by leadman. They can also start with KYXXXX

Anyway. Here is a circa 2005 ATNG AP-500X with all (visibly) good fujiyyu caps.

Most of the capacitors were bloated, so I replaced them all with the better quality Fuhjyyu (comparatively better than what was in there!) from an Antec I recapped.

Yeah, considering the original ones were Rulycon . I doubt there's anything worse than that (GSC/Sacon/Evercon comes close, though, but that's on the motherboard-side of things).

I have a crappy store brand "CompUSA" 250 watt power supply - marking on the pc board is LP6100, so it is a cheaply made L&C product.

Actually, L&C is with Deer and Allied. Solytech is the company behind these three. The one you have is a Leadman/Powmax (as indicated by the model number).

Most of the capacitors were bloated, so I replaced them all with the better quality Fuhjyyu (comparatively better than what was in there!) from an Antec I recapped. I checked all the Fuhjyyu caps for ESR, so they are all "good". Then I fired it up with a light load, and shortly thereafter blew it out - shorted the main switcher and cracked the pwm chip. I am convinced that ALL of the parts used on this one were cheap low quality. So I replaced the pwm chip, the main switcher with a new Fairchild 18N50, and a buffer circuit between PWM output and the 18N50, Now lets see if it can blow out that switching transistor!

Every once in a while, I fire it up, beat on it, put a heavy load on it, etc. So far it has held up. But I am still curious which will fail first - the Fuhjyyu capacitors or the 2 transistor 5vsb circuit.

Fujhyyu and 'good' is an oxymoron.

TBH, i don't really care HOW it works if it DOES work. Even when i know all the internals. Besides, it isn't that likely to blow with just one HDD as load.

And it certainly isn't a permanent solution, it is inconvenient and noisy. However the permanent solution involves a buck converter feeding off the 12v rail and pumping extra power into the 5v rail. With full protections, i don't wanna fry this nice motherboard that i just bought, heck, i didn't even have the time to voltmod it yet.

That sure as heck sounds a lot complicated than just running a second ATX power supply for that hard drive.

I know you wanna. But just asking... I have this "Torent" power supply ("Torent Computers" is the name of a computer store here, so it's simply a no-name with reprinted labels). It came in this **** AMD box that i got for free, fried CPU, semi-fried HDD, 512MB DDR, no video card, gave the mobo and RAM to a friend and it works fine, threw away the CPU.

The only thing remaining in the case was the PSU and some random ass CD writer. I powered it up initially and it emitted a loud ~18kHz whine (my hearing is quite sensitive to high frequency), i found it objectionable so i just shut it down and didn't think about it anymore.

Well, long story short (this is something for a later occasion), i needed a secondary PSU to run the SATA HDD in a dual PIII Tualatin system that is *extremely* 5 volt heavy. So heavy, that after buying a mobo that would run the CPUs at their full 1.4GHz, there was not enough 5v juice left to run the hard drive anymore! The only PSU i had with a SATA connector was this piece of junk. So, before entrusting my HDD to it i took it apart to look at it. Same EI33 core, filled to the max, and with rather thin wire i must add. Full of dust of course. But imagine my surprise when i saw... Fujhyyu caps!!! And they're *GASP* ALL GOOD!!! Plugged the hard drive into that power supply and guess what, working fine... It does however appear that this PSU runs in the upper end of the audible range, not even at the usual 33kHz for old PSUs, as the whine is quite annoying and is present all the time. But for all intents and purposes (and for older people that don't hear up to 18k anymore), this PSU is fine. And it's over 4 years old certainly and has been used heavily according to the amount of dust inside, so it's nothing like those Antecs that would work fine when new but crap out in 1 year at most.

Now, just tell me you want those pics.
