Re: Power supply build quality pictorial. part 2

but, i see a bridge rectifier in place of 4 diodes. not bad. heatsinks ok, looks fixable. but who in the hell would buy something with that name? sorry, but that name sounds a bit.... uh... girly...

Sold in the US as kingwin.

Actually pretty good now, just the soldering needs work.

ENlight GPS-400AB B 350W (Delta OEM)





both Caps on primary side are SAMXON 560uF/200V.
used STPS2045CT for 3.3V, 2xSTPS2045CT for 5V and SPTS20S100 for 12V.




I don't know Caps brand on secondary side.

Re: Power supply build quality pictorial. part 2

Today a friend gave me a psu, asking me if I can examine it and find out why it stopped powering on his pentium 3 800mhz system.

I uploaded some photos...

Re: Power supply build quality pictorial. part 2

pan star? geez, i think its time for a new rule:

____ (blue, echo, pan, ect.) star= POS that is too light for a paperweight.

look at all the jumper wire!

few/small/bad caps

no x/y caps

no choke

wimpy heatsinks

4 diodes

tiny primary caps

thin wire

weak silicon


i bet the metal is so thin that it would make a lousy doorstop.

Re: Power supply build quality pictorial. part 2

Yea, secondary side is almost worse
2 transistor 5vsb circuit
2 diodes for +12v
No Pi Filters
Only one coil
Only 3x Tiny Tiny capacitors

goodpsusearch; This PSU is too much work to fix so it becomes reliable
These two lengthy threads are about fixing PSU's such as yours incase you are interested... (A few pages in...)

I will tell him to throw it away and keep the fan and some parts.

Re: Power supply build quality pictorial. part 2

Today I got 2 psus for free from university. One of them is Maxpower PL-400 400watt and unfortunately is not working.

When I opened it I could see why... Bulging HEC 820uF 200V primary caps, bulging Fuhjyyu 16V and 10V secondary caps...

other cap brands in this psu are jee and capxon. Couldn't write down a full capacitor list, sorry.

So, what do you think?

[370forlife]

Re: Power supply build quality pictorial. part 2

Wow, it actually has APFC. The big coil by the main caps is the APFC coil, the board behind it with a IC on it is the APFC controller, and the schottky on the primary heatsink is the PFC diode. Looks quite good actually, just replace those caps as well as a more detailed shot of the components on the secondary heatsink would be nice.

[goodpsusearch]

Re: Power supply build quality pictorial. part 2

Actually, I was thinking of returning it, because the bulging primary cap replacement along with the bulging secondary ones and all other crap brand caps will cost me much more than the psu value...

Today, I recieved some of the caps I ordered for the antec psu (https://www.badcaps.net/forum/showthread.php?t=8223) and the macron power (https://www.badcaps.net/forum/showthread.php?t=8171) and I am waiting for more... RS site only sells in sets of 5 or more caps, so the final cost is expected to be more than 50 euros.

I wil post photos of one more maxpower that I got today, this one is 300watt and working (but no pfc).

Re: Power supply build quality pictorial. part 2

That power supply is worth the caps. If the manufacturer went as far as to put APFC on it, it has to be 1/2 way decent.

Delta DPS-400MB-1A

+3.3V@15A
+5.0V@20A
+12Vp@12A

+12Vd@6A
Max. POWER 400W
+12V TOTAL POWER 340W MAX.

No label on this unit except IBM P/N 39Y7330
I've googled found on China site => http://bbs.ncdiy.com/dispbbs.asp?boa...&star=1&page=1

Primary cap is Nichicon, most of others are Rubycon, just one Chemicon 3300/16V on 12V output filter.

Re: Power supply build quality pictorial. part 2

Got an old CWT unit, rated for 300w, never used, however this is a VERY old unit, having been built with a -5 rail. It's also filled to the brim with Fuhjyuu capacitors, except for one lone CapXon on the secondary. It does have decently sized heatsinks, and decent fannage as well (some Sunon unit), so it pisses me off to see this kind of penny pinching. My question is, is it worth the effort to recap it?

[goodpsusearch]

Re: Power supply build quality pictorial. part 2

I would recap it and keep it. It seems well built.

[Krankshaft]

Re: Power supply build quality pictorial. part 2

Look in that Blue label CWT (Channel Well Technology).

The builders of the original Antec supplies bad caps but decent supplies.

[Toasty]

Re: Power supply build quality pictorial. part 2

If you have a use for it, then recap it. If not, put it in the archive and recap it if you find a need. Check the voltages so you know -now- if there's a problem.

>>... never used ...<<

Umm..., I think the inside of the cover tells a different story...

or just dirty fingers?

Re: Power supply build quality pictorial. part 2

It did sit for a while gathering dust, but may have been lightly used. Obviously not for long, as those Fuhjyuu caps haven't puked their guts out. :P
