PC Power & Cooling 510 - Kill the Teapos?

[Trinite]

I have a PC Power and Cooling Turbocool 510W model. It has Teapos inside, much to my distaste. However, I've never heard of PC P&C units blowing up, so it would seem that either PC P&C used a decent series of Teapos, or that the PSU is designed so that the capacitors are utilized well below their rating.

I plan on selling this unit, which is probably 5 or 6 years old. Should I replace the Teapos, just to be on the safe side, or should it be fine as is?

Teapo usually do okay in PSUs.
If none are bloated I'd leave them alone.
If any are bloated I'd replace them all.

As PCBONEZ said, Teapos are usually fine in PSUs. It's the motherboard-grade Teapos that suck wind, hard.

They aren't as reliable as some of the Japanese brands, but they aren't "bad caps". I had a GX260 with a PSU full of Teapos. I bought the GX260 off a school who was getting rid of them. I know a guy who is a teacher there and he said they practically never had their computers completely turned off, so maybe 6-7 years of constant use. Nothing too demanding, but nonetheless, not bad.

I consider teapo to be very bad (not quite as bad as fuhjyyu, but close). I'm sick of pulling them bloated from 2 and 3 year old PSUs. I always replace any Cheapo Teapos on any PSU I get my hands on, bloated or not.

Really? A lot of old Dell units I've opened up have had Teapos. (Maybe 6 year old PSUs). None have failed.

I think it depends on how cool they've been kept, how much ripple they've endured, etc. I still have graphics cards with Teapos which are okay, and have been in well ventilated cases.

Also the topology.

If it's a cheap PSU with one OP cap on each rail I'd expect Teapo would be more likely to have problems.

I have 5 'Sparkle' [FSP builds] 460W that are about 8-9 years based on cap date codes in them.
They have the three cap OP filters. [These are heavy PSU's built for tower servers.]
They are one of those double-decker 2-PCB designs with one end fan and the PCB's are packed so airflow is probably not so grand back at the OP caps.
All but one unit had one bad Fuhjyyu in +12v.
One or two had 2 bad OST in +5v.
All the other OP caps were Teapo so there were around 40 Teapo in all.
Only 2 bad Teapo in the bunch.

The ones I usually pull failed teapos out of are Hipros, HP-D3057F3H models to be exact. There seems to be one on the 5vsb which always fails and the PSU stops working, but I have also seen bad teapo in other PSUs including a few FSPs (and no, they weren't next to any load resistors).

Re: PC Power & Cooling 510 - Kill the Teapos?

Sounds like possibly a case of Hipro choosing the wrong cap for the application.
That sux but it wouldn't really be Teapo's fault.

Are the +5vsb Teapo 8mm?

Found one of those to look at.

Yes, they are 8mm 1000uF 6.3v

After an inspection, they all seem in good shape. So I think I'll keep them in there. It would a hassle to recap anyway, since the PSU is a very cramped design.
