Re: Dressing up (a "450W" ATX supply) for Halloween -- YueLin YLP-013
I found two (different) X2 capacitors, one labed IEC384-14II
55/100/56X2 250V~, then on the backside (frontside?) it's labeled
OKAYA RE224 0.22uF K 275V~ iP, and black in colour. The other one
is labeled MEX/TSC MKT GPF .1 M 250V~X2 40/85/21 211, then in the
bottom left is 565-1, blank on back side, and orange in colour.
Due to spacing, I've placed the shorter (orange) one by the bridge
rectifier, and the slightly taller one (black) one closer to the
input...

Re: Dressing up (a "450W" ATX supply) for Halloween -- YueLin YLP-013
So here are the parts I have harvested so far, and might be good candidates for
upgrade use. I don't really know how to tell if one transformer is better than another
one, but the size of the one I've extracted, labeled DVE E401201-014, is slightly
larger than the one that's installed by default in the YueLin. The pinout is at least
two pins on the input side, and six pins on the output side, with the "out-the-top"
center tap to ground. The spacing on the...Leave a comment:

Re: Dressing up (a "450W" ATX supply) for Halloween -- YueLin YLP-013
Alright, I've picked up a few more "bad" supplies, and I suspect I got
lucky with regards to a compatible transformer, and NPN power
transistors. Now, the YueLin's original primary switching parts are
labeled:
0107
P13009-0
And although I don't know who makes them, I notice that there is an
FJP13009 "High Voltage Fast-Switching NPN Power Transistor" from
Fairchild Semi. which these are likely similar to.

Re: Dressing up (a "450W" ATX supply) for Halloween -- YueLin YLP-013
Alright, this morning I did a scope test using an HP 16500B. For a light load,
I attached one hard disk, and two additional fans to the YueLin YLP-013.
I took two shots each with the scope set at 1ms, and 10ms. The A1 channel
is connected to the 5V output line, and the A2 channel the 12V output line.
Each channel is offset/centered by/on it's respective "correct" voltage,
5V for A1, and 12V for A2, and the scale is set to 250mV, so each is slightly...Leave a comment:

Re: Dressing up (a "450W" ATX supply) for Halloween -- YueLin YLP-013
Here you may see the recap itself, with one additional point.. when I took that
decapped output stage pic, I had only removed the micons, and not yet the
canicons from the output stage. I ended up putting those two "Low ESR"
Canicon 470uF 16V to replace two Micon 470uF 10V on the 5VSB circuit.
I don't know if that's a good idea or not, but I figured I'd remove Micon entirely,
and so this leaves me with only Canicon (presumably not-the-best) and
Nichicon...Leave a comment:

Re: Dressing up (a "450W" ATX supply) for Halloween -- YueLin YLP-013
Here is the input filter stage installed on the YueLin, with also two "Y rated caps"
in the X cap locations (is this a bad idea.. let me know if you think so). These Y caps
came from the SGI's Lucent supply. Also you can see in this image the thicker
input wires I've installed to the PCB....Leave a comment:

Re: Dressing up (a "450W" ATX supply) for Halloween -- YueLin YLP-013
I got the primary input filter from this Wan Nien Enhance Electronics supply,
and this is where I also got that 6Amp bridge rectifier that I was considering
installing in the YueLin. See what I mean about the pcb near the rectifier itself
and the input coils all seemed fine, but obviously they've had quite the "burn in"
load test (pun intended).
The capacitors on this board are Jamicon and Teapo. The Jamicon seem fine,
but the Teapo's were bulgy. Is...Leave a comment:

Here are the before pics, where I'd just taken the PCB out of the housing.
3x from the top, and 3x from the side. I can't take anymore, 'cause it doesn't
look like this anymore (more pics to follow):...Leave a comment:

Dressing up (a "450W" ATX supply) for Halloween -- YueLin YLP-013
So I have a supply labeled "ATX Switching power supply MODEL:450W",
which is quite suspicious sounding already, but worse still is that
there doesn't seem to be anyone claiming to be the manufacturer.
There is a sticker labeled "200808023681 WP08023 Made In China",
which seems to be the most informative indication on the outside.
Input/output specs are listed however, and this is how they read:

Re: Completely rebuilt YueLin YLP-013
@humblesmith1 -> the part number for Q7 on my Rev 2.2 YLP-013 is: C5027 080801.
I found a datasheet for a Fairchild Semi. KSC5027, so perhaps this is a clone of that chip? The Fairchild part is labeled "High Voltage and High Reliability NPN Silicon Transistor" and has the pinout 1.Base, 2.Collector, 3.Emitter. Hope this helps someone (2013-2011 = a long time). I'm rebuilding my YueLin, and will likely start a thread on it once I get a little further, and take some pics, etc, to let the legend of rebuilt YLP's continue...Leave a comment:

Re: New Members - please post your introductions here
If you can't tell by my name, I need(ed) to see pic(ture)s before attempting an ATX supply fixup... Perhaps if it powers up when I'm through, I'll post my results.Leave a comment:
