Re: Zalman ZM600-HP blowing PFC's
maybe you should check the smd transistor under the pfc mosfet. (that drive the pfc mosfet) sometimes this small parts fail and make small value resistor (2ohm - 5 ohm smd resistor) that connected to mos pfc's gate burnt & open.

Re: Antec Truepower trio 550w
it will work, or you maybe have to use something bigger.
just make sure there's nothing wrong with mosfet / primary caps, some times they shorted & burnt the NTCLeave a comment:

Re: is this refurbished psu?
54$ the cost down version of s12-ii. rated at 400w, only 220v input (single apfc mosfet)
seasonic eco - 400
all using taiwan / chinese caps.. not sure.
this is a brand new psu.
70$ the 'original s12-ii' 520w. all japanese caps....Last edited by ipo3nk; 11-12-2012, 07:45 PM.Leave a comment:

is this refurbished psu?
i found few model of seasonic that quite old still on sale in my country.
the seller says that the psu is new non refurbished.
but if i look in detail, all of them had old manufacturing date on their parts
the tranny, capacitor & semiconductor date code too old for a new psu.
check this out.
it cost USD82$ listed for 600w
tranny date code 0809, (year 08, week 09)
like excact copy of tx650? including the manufacturing date!
if you search the batch number in capacitor, it also says 2008 parts.
afaik, psu makers never...Last edited by ipo3nk; 11-12-2012, 12:37 AM. -
Re: Fortron BlueStorm II (FSP500-60GLY) nothing but +5V SB
hopefully this schematic help.
the z41 is 18v, & c41 100uf
theese parts & all secondary caps [B]always[/B] fail after 3+ years operation.
thats why they only gave 2 years warranty. WTF!Re: Fortron BlueStorm II (FSP500-60GLY) nothing but +5V SB

Re: Fsp350-60hlc
are you sure the ic is DM311? not DMO270 / 265?
DM311 have 7 pin soldered, 1 pin NC
DMO270 have 8 pin soldered.
looks like the ic completely fried... :p
there is no R11 in you pic.
the one you marked with red rectangle is R44.
R44 is fusing resistor. the value is equal to R42.
some model come with 2 ohms.
the higher efficient model come with 0 (zero) ohms
if R44 blows, something at standby circuit is short.
you should check Z42 after remove the fried IC first.

Re: CapXon
capxon = the only brand i found to be fail / dried / zero capacity / SHORT in APFC part of psu..Leave a comment:

Re: help, PSU without PG SIGNAL
@pc bonez: i'm testing with active load, monitoring all voltage output with DMM.
then tested the PSU with various mainboard. msi 740, intel g41, albatron nforce4, gigabyte 890FX ud7, intel S3420GPLC. the intel s3420gplc wont turn on if PG signal out of spec.
@everell: how much voltage at PGI if normal?Leave a comment:

Re: help, PSU without PG SIGNAL
the PGO only 25-100mv
the diode d90 (1n4148) and r92 (100ohm or 51ohm) replaced and still have the problem.
in the PGI signal source network, only a zener diode and a smd caps i haven't checked. i dont know the value of this parts.Leave a comment:

Re: help, PSU without PG SIGNAL
even change the chip (ps223) does not fix the problem.
what do you mean by put the sense wire to 5v?
give fake PG signal from regular 5volt rail (desolder the grey cable and put it to 5v rail?)?
already did it by connecting PG signal wire via 1N4148 to 5volt, giving PG signal delay to 0ms.
ATX spec have delay on this signal about 100 - 500ms.
with this 'temporary fix' the psu can turn on 90% mainboard.
some main board cannot boot with PG signal 0ms.

Re: help, PSU without PG SIGNAL
tried to change ALL of caps. but still the same.
the caps only teapo, capxon, ost.
still have about 10 psu with this kind of problem.

help, PSU without PG SIGNAL
i have a few fsp based power supply, 60GLN series
the internal is identical to this thread:
[url]https://www.badcaps.net/forum/showthread.php?t=11662[/url]
1. the problem is the PG signal is missing if i load the 12v rail over 20A (combined) this is not the OCP limit.
i have active load to test it
2. another psu have normal PG signal at first, but if i restart the psu / computer, the PG signal were lost. if i turn off (then turn ON) the psu via switch (disconnect the AC outlet) then turn on via PS-on, i have the PG signal again. but it lost again if... -
Re: The worst of the Fakes
hahaha lots of these caps in indonesia.
they filled the can with glue, rock, sand, cement..
everything that keeps the can from floating in the water.Leave a comment:

Re: Amacrox AX650-GLN Free Earth
i have the same psu from FSP, 60GLN series
but i replace the 100uF/25v with NCC KZE 100uF/35v or NCC KY100uF/25v
and the 2200uF with panasonic FC 2200/6.3v
thats the only caps that i can get in my countryLeave a comment:
