Antec Truepower 380S

[tazwegion]

I recently acquired an old Antec TP-380S and while I was removing the Fujjyyu capacitors (which looked remarkably intact) I noted that one of the primary input capacitors (Panasonic 820uF 200v) had a slightly domed top.

I've never bothered with the primaries before as they've always proven to be fine in past rebuilds... but I suppose there's always a first time eh? This unit is supposedly unique to Antec's Sonata case line up being fitted with only 1 (low RPM/noise) cooling fan instead of the usual Truepower Series configuration of 2, this may be the reason for the primary's degradation

Has anyone had any prior experience with these altered 380w PSUs before?


Thanks to davmax I was able to source some otherwise locally unobtainable 2200uF 16v Samxons and complete this project

Yes, replace that primary. In fact, replace both of them. They both got too hot!

It's only 85*C rated, so if it's in a hot running power supply, it wouldn't be that hard to kill, even though it's a panny.

Yes I have to say I thought the same thing... I pulled 2 x 1000uF 200v primaries from a dying Codegen 550w PSU and used those, so far the Antec has been running flawlessly though I really need to address the low RPM fan as it's in an Athlon 2100+ gaming system (2100's ran really hot right off the bat), thankfully the case is well ventilated

Yeah still it's a pity about the Panny's though



EDIT: I notice you like to toss bad caps into fires c_hegge... isn't it cool how the pop?

easiest way I find to adjust the fan in those older antecs is to put a 2.4K resistor in paralell with the thermistor.

You didn't put crap caps in did you?

It's very cool. I love seeing them pop and it's a great way to get revenge on those fuhjyyus that kill your PSUs (and motherboards).

What's even cooler is CMOS batteries. When they pop, bright blue sparks go everywhere, like DIY fireworks.

Excellent suggestion, many thanks!

No I used the best quality capacitors I had on hand at the time... the system has been run hard these school holidays without issue so considering the small outlay for parts I'm happy with the outcome
