3R Systems PSU on Hardware Secrets

[Rulycat]

Take a look at this:

Good performance, but who's the OEM? Reminds me a bit of some Sunpro units, or maybe ATNG.

Notice the "Kingcon" caps with the Suncon/Sanyo K-vent.

It's reported to be Golden Tiger GT-ATX-500-800



I've noticed the Kingcon caps also, because Jonnyguru on his forum was asking about them a while ago and then this psu popped up.

They're taiwanese but that's pretty much all that's known about those.

IMO, no PSU with anything non-japanese should even get a bronze award, let alone a silver, regardless of how well it performs.

Teapo seem to do okay in newer PSUs.

Re: 3R Systems PSU on Hardware Secrets

I frequently pull bulged teapos from 2 and 3 year old PSUs, even when they are decently cooled and appear to be the correct series for the application. For that reason, I always call them cheapo teapo

What makes of PSU? I know those crappy little FSP strips of alu don't exactly help.

Re: 3R Systems PSU on Hardware Secrets

I've seen it in PSUs made by HiPro, huntkey, CWT as well as FSP (and probably a few others) Even when they have massive heat sinks and run cool. Even OST and capxon seem to hold up better than teapo. In some cases, they had a mix of fuhjyyu and teapo, and the teapos failed before the fuhjyyus (even though neither were near any particularly hot components).

Ah righto. Run cool in Aus? You must be having a laugh.

I'd be interested to see some long term stress tests of different brands in the same conditions. You can't go by MTBF.

Re: 3R Systems PSU on Hardware Secrets

They can run cool when there's air conditioning. In any case, though, I've been replacing them with Nichicon HE. I've yet to have one come back.

This is so not true!!!

Re: 3R Systems PSU on Hardware Secrets

I know capxon and OST have MUCH worse reputations (and I still trust them less), but I see at least twice as many teapo failures as OST and capxon combined.

No way. - Absolutely not what I see.

Teapo failures are rare compared to those other three brands.

If you see 1000 Teapos in PSU's and 10 OSTs or Fuhjyyu then quantitatively more bad Teapos doesn't make a worse 'rate' of failure.
-
Also if you are seeing them bad over and over in basically the same PSU's and that isn't necessarily the fault of the caps.
-
IOW:
If you see 50 Dell GX-2xx boards with some bad Rubycons and one Asus board with good OST that doesn't mean OST is better than Rubycon.

In my experience OST and Fuhjyyu are -at least- 10 times more likely to be bad than Teapo if you go by percentages instead of raw quantities.
-
In PSU's I see at the most 5% of Teapos are bad and OST/Fuhjyyu are easily 50% or more failed.
- That's with mixed PSUs though, which isn't a good way to compare.
[Capxon is somewhere in between but they seem to be getting worse as time goes on.]

In some cases, they had a mix of fuhjyyu and teapo, and the teapos failed before the fuhjyyus.

There is a 460 watt Sparkle/FSP I like so I've easily done over 20 by now.
Heavy units, 3-Cap PI OP Filters.
I sometimes use them in 'light servers'. (3 or less hard drives.)
[It's a similar design to the AcBel unit people like for some reason but all the OP caps are 12.5mm so they are very easy to find choice replacement caps for compared to the AcBel with all those bastard 10mm OP caps.]
-
The caps mix is ideal for a comparison here.
[Layout]
OP cap count - 5x Teapo [always] and 4x OST or Fuhjyyu.
[OST/Fuhjyyu brand used varies unit-unit with maybe 80% being OST.].
3x of the Teapo [on 3.3v OP, always Teapos] have iffy cooling.
2x of the Teapo and the 4x mixed brands have better cooling due to location.
[Of the 20+ Units]
- 3 bad Teapos total so far.
- 4 good OST total.
- Zero good Fuhjyyu.
[So, taking 20 PSUs.]
Out of 100 Teapos - 3 bad. [3%]
Out of 80 mixed OST/Fuhjyyu - 76 bad. [95%]
- - And that's mixed brands in as close to the same operating conditions and history [per unit] as you can possibly get without doing a formal test.
.

So, IMHO:
If those Teapo you are replacing were OST or Fuhjyyu instead the result would be the PSUs would fail much much sooner.
