Help with identifying PSU board (possibly Tagan?)

[wacce]

I recently picked up a PSU board from trashes. The board is mostly intact, and no parts are missing, so I was wondering if it was worth saving. All info on the unit is appreciated. This unit suffers from bad Fuhjyyus, surprice surprice.

The board seems very similar to Tagan PSUs, here's what I found from the forums.

Tagan 480W: https://www.badcaps.net/forum/showthread.php?t=3230
Tagan TG330-U01: https://www.badcaps.net/forum/showthread.php?t=12484
Tagan TG380-U01: https://www.badcaps.net/forum/showthread.php?t=14353

The fan controller is placed at the top of one of the heatsinks, like in TG330-U01, but unlike in TG380-U01 or 480W. My unit also has a different fan, which has some kind of LED light in it, label reads "ribbed led all blue, sleeve bearing, 12V 0.2A , RL4B S08025LD". That made me think, that it might be some other brand than Tagan. The unit has had two fans, the other one was taken by the previous owner.

There are very little marking on the board, the ones I could find were "P022-E" and "(CF) 03 94V0, E199724" in sixth and seventh pictures. Found out that "E199724" refers to manufacturer Cheerful Industrial Co., Ltd. Also COPYRIGHT 2003 is written a couple of times on the board.

Thanks in advance!

Thank you for the link! The i-Xeye unit seems almost like the one I have, except that mine has fan controller circuit on the top of the heatsink, and in all pictures I found of i-Xeye the controller was on the side. Different versions maybe?

Re: Help with identifying PSU board (possibly Tagan?)

My discoveries so far: the board layout and heatsinks resemble most Tagan TG330-U1, but my unit has different fan(s) AND it has a red switch at the back panel (switch cables are attached to the remaining fan). I found some Tagan units with a similar looking switch for using 12V rails as separate or combined, like in TG430-U22.

Other possible brands might be Topower or Epower, but haven't found any units that are similar enough.

Re: Help with identifying PSU board (possibly Tagan?)

Seems like I'm spamming my own thread while I find out new things

I realized that the red switch is a three step switch for regulating fan speed, and it was only disconnected from the fan controller circuit. These switches can be found at least in E-power PSUs, like Cougar (link) and Xscale (here) series.

It is also now obvious to me, that this PSU is made by Topower, and might be supplied by one of it's associates (OCZ, BeQuiet, Tagan, E-Power).

Topower TOP-400P5/450P5/520P5 board/heatsinks are looking very similar, as can be seen here and here. Taking into account the size of main caps, in my case 470uF, TOP-400P5 seems to be the only one to match, as TOP-450P5 has 1000uF main caps.

Feels like I'm getting closer ...or maybe it's just me.

Bingo.

Be Quiet! Colorline 2 Fan (Titanium), 400W version.

I got lots of search results of finnish sites, which gives me more reason to believe that I got it right.

Thanks you selldoor for helping me to the start, I might have ended up using a lot more time on this than I now did!

I've got a blown-up Antec Smartpower SP-450P, which I can take the cables from, and some old PSU cases with similar dual fan layouts. Seems like the unit doesn't originally have SATA-cables, but I guess adding them now doesn't hurt right? I'll let you later know how the project progresses

Reminds me a lot of my topower built Global Win SAF450 (http://hardwareinsights.com/wp/2011/...saf450-review/). It is a half decent design, so if you can get it going, it will be worth hanging on to, but that could be easier said than done with the damage to the PCB.

[wacce]

Re: Help with identifying PSU board (possibly Tagan?)

The innards of SAF450 are almost identical to this BeQuiet. Additional 50W would have been nice, but 400W should do in many systems.

Actually the damage on the board is not that big, only the +12V through holes got little bent and they haven't even broken from the PCB. To make sure the connection is ok, I'll solder an additional wire on the trace, over the bent bit.

Re: Help with identifying PSU board (possibly Tagan?)

The extra wire is probably a good idea. Replace all the caps and see how it goes. Check the primaries too, as these PSUs are notorious for killing them.

Re: Help with identifying PSU board (possibly Tagan?)

Sorry for my lack of knowledge, but is the EMI filter replaceable with just any (new enough) other EMI filter circuit from for example Antec Smartpower? Antecs circuit seems a bit more compact, and I was wondering if it's compatible. Picture attached.

[c_hegge]

Re: Help with identifying PSU board (possibly Tagan?)

Yes, you can replace the EMI filtering components. They are all compatible, but bear in mind that they can be physically different sizes, but if they fit, they will work.

If that smartpower is really wrecked, then you could probably put the Topower in its case. I used a smartpower case when I was re-building my Rexpower/Key Mouse PSU.

Re: Help with identifying PSU board (possibly Tagan?)

Excellent, thanks for the reply.

I was considering using the Antec case too, as I'm a little short on two fan cases. With my current level on knowledge, Antec is not an easy case. One resistor near the other heatsink is totally fried (pic. attached), and I believe this PSU went out "with a bang", taking some other components with it. Interestingly, only those two caps near the burnt resistor and one main cap were bulging. Anyway, it might be doable but seems like a good amount of work, going through all the transistors is necessary I believe.

Also, Antec is pretty much the only one which has decent cabling left

Re: Help with identifying PSU board (possibly Tagan?)

If you're gonna fix the Antec, you're probably better off replacing the whole 5VSB circuit with a PWM IC based circuit. everall has done it a few times to Antec SP-xxx (https://www.badcaps.net/forum/showthread.php?t=19291).

If you decide to put the Topower in the Antec's case, you would get away with only one fan, and it looks like you still have one of the fans that the Topower originally came with

[wacce]

Re: Help with identifying PSU board (possibly Tagan?)

That actually seems quite interesting. Maybe I'll save the Antec for later, as they tend to be very nice PSUs after some modding.

There is indeed one fan still left, but I'm not sure if it provides sufficient airflow. From the reviews I read that the fans are VERY quiet, so I'm guessing that they don't spin very fast. I think I'm going to use two fans, just to be sure. I might combine one old single fan case with different top cover, which has a place for 92mm fan. We'll see.

Re: Help with identifying PSU board (possibly Tagan?)

You could also put an ~6K resistor in parallel with the thermistor on the fan controller. The reason these PSUs are quiet is because the fan controller spins the fans very slow untill the PSU really starts to cook, then they will become louder. The 1 fan should be enough airflow IMO if you mod the fan controller

I agree. I fan mod most of the power supplies I fix just to be safe they don't cook caps (or toroid coil) again.
