Re: Rosewill Glacier 600M (Awesome eBay score!!!)

Nice score P4!

Looks capable of 600W, definitely worth a recap, didn't know Rosewill sells Andyson units though all Rosewill PSUs I've owned were ATNG made not a single problem with any of them , that four schottkys in 12V are overkill for only 45A why would they do it? lower Vf perhaps? my [URL="https://www.badcaps.net/forum/showpost.php?p=666983&postcount=2617"]Rosewill RG630-S12[/URL] uses only 2 X S30D60C.

Re: Caps choice

As Pentium 4 already said don't use those TK caps, there's no point in replacing unreliable Seacon caps with unreliable TK caps also the change in ESR/Impedance may be too drastic and may also affect the cutoff frequency of output filters, watching the datasheet the impedance ratings of those Seacon RS caps are really high (around 100mohm) so even KZE and/or FM may not be suitable for your PSU. I say if it is working and you have no other choice of caps better to leave it as it is for now until you get better quality caps.

Put back...

Re: Xtreme Gear PSAZ-600

Great job, as always!
Remember those resistors are the minimum load needed for stability at minimal or no load conditions, i wouldn't attempt to explain exactly why they need a minimum load because there are too many things involved and don't even fully comprehend half of them but each design reacts different when changed, some give crazy voltages but stay on (usually crappy ones), others shut down after a couple of seconds or right away as yours.
If the power distribution from the 12V rails is right this PSU fits a...

Re: Fortron 200-50SNV(PF) SFF - dead, no 5VSB

Missed this, can anyone on 230VAC mains confirm if this is right?, i'm on 115VAC so no idea.

Somehow I missed this, it looks like a glass discharge tube (GDT) but not sure, IF it is a GDT it should only "arc" under surge conditions so it maybe be faulty and it could potentialy killed 1H0165R but i'm just guessing you need to test the IC ,also as others have said check/change the startup capacitor.

It's not that complicated really, 1H0165R is a PWM + FET and switches the SB transformer,...

Re: Xtreme Gear PSAZ-600

It may be the resistor change, try to put some load in 5V and 12V rails, if that fails and you're absolutely sure that there is no solder bridge, then put original resistors and try again, also re-check caps polarity.

That's what i do when it happens to me

so maybe i'm guessing it's wattage wrong, but then again it's no purpose to put a 20A rectifier in a 2 rail psu, are sure it only uses one 20A rectifier?...

Re: Xtreme Gear PSAZ-600

Powerfull enough for even something a little bit more demanding I would say, so you recaped this? does it have two 12V rails or is it a single rail design?...

Re: Xtreme Gear PSAZ-600

The thing is 20A in 12V Rail will not happen that's not the 12V rating in a sub 300W PSU

30A schottky for 12V? ...mmm don't think it needs more than 20A, would bet the protection kicks in before you reach 20A in 12V rail....

Re: Fortron 200-50SNV(PF) SFF - dead, no 5VSB

In the 2nd pic you've posted there is a cap with some residue at the top, it could be leaking also there is no 2-transitor circuit in this PSU the 1H0165R is in charge of the 5VSB circuit so asuming the fuse is good if there is no standby you must start by checking if 1H0165R is shorted or faulty, i'm attaching 1H0165R datasheet and a schematic close enough to your PSU, hope it serves you as a guide to troubleshoot.

Once you got it running again i strongly advice you to replace at least all output caps....

Re: Xtreme Gear PSAZ-600

Hmm so old design refited to "modern" requirements? ...interesting, definetly usable if recaped and the EMI/Input section gets properly populated, too bad it's a 5V heavy design but if it can do at least 230W then is enough for most applcations on a modern computer, does it really have shunts to separate the two 12V rails?? pics don't show, well even if it is a single rail design it's probably the best Linkworld i've seen compared to the ones i'm used to see here in MX.

IDK but he must be on a quest to recap...

[B]Rosewill RG630-S12[/B] (ATNG design)

I really like this PSU except for the Teapos and the blown TNY277, it's the same model [URL="http://www.hardwaresecrets.com/rosewill-green-series-630-w-rg630-s12-power-supply-review/"]reviewed long ago at HS[/URL] but definitely a newer revision, was "gifted" to me as a "for parts" unit but turned out to be an easy fix and it's now working without problems. I plan to do a full recap and use it in my main rig so what do you think guys?

Yes I do, the third one next to the toshiba transistors is D27 = HFA08TB60 it's the PFC diode, on the backside of the heatsink the lone transistor is Q6 = FQPF2N70 this is the 5VSB transistor and the rest are Q3,Q10 = 20N60C3 the PFC MOSFETs....

Well those stencils doesn't look that bad to me, if datecodes in HZ are from 2 years ago like the HN it may be just the result of handling in the warehouse.
I don't know about HN or HZ but HM was still in production at least in Q1 of present year....

Re: Cap Datasheet Depot

Here are ChengX DS, this ones were not taken from ChengX website but from a distributor in HK ([URL="www.bentex.com.hk"]Bentex[/URL]), cause those were the only ones I could find in HTML version, I checked like 7 random DS against the ones in ChengX website and all matched, DS were slightly reformatted to make them more readable and then converted to PDF.

Re: the gutless, bloated, and fried power supply hall of shame

Cutting the circuit shouldn't be a problem, but you'll need to ID that switcher and get the DS to understand what (if any) changes are needed to successfully "implant" it into another P/S, also note that the feedback for SB is done using one of the two built-in shunt regulators (TL431) in the SC6105 chip....

Yeah at first sight I took them for ChengX too .
