PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

[8832]

This supply QQE100/QQE98 is product brand QET taiwan and is specialy apply for industrial book PC Protech systems taiwan PS8060 with motherboard PROX-3600 and Angel systems PX-80. This pc used in gaming machines MAGIC GAMES I, II, VLT, VNT and others - Novomatic group.

This supply with active PFC with date production 2006-2008 used to secondary site standard caps brand CapXon type KM with livetime 1000hours/105 celsius and lifetime supply is nonstop function 1.5 year. New products used sometime caps Teapo SC 2000-3000hours/105 celsius and this livetime teoreticaly 3years.

If replace all caps in secondary site in repairing and use caps Teapo SY 5000hours/105 celsius, then teoretical livetime this suply is 5-6years in nonstop function.

If you're running them at 105°C, WOW!!

Hour ratings are based on the spec'd temperature. At 105°C then yes, 1000 hours. At 50°C, then perhaps 25,000 hours... (there's 8832 per year...)

Go get the datasheets for those. I think you'll find the SJ series a better choice in as far as its ESR is lower and the ripple handling is higher.

Hello 8832.

Welcome to the Forum.

What you are trying to say is a little unclear.

Are you asking if a Power Supply will last longer with Teapo SY caps instead of CapXon KM?

Or are you an engineer from QET that is stating this as fact?

The general idea around here seems to be that both CapXon and Teapo are not very good. Not actually bad but not great.

Have Fun,

panasonic fc do fine in game psu and monitors.
i have seen some i rebuilt 10 years ago that are still fine.
got a merit megatouch in now that all the teapo in its 2 year old psu are blown up.
no fan failures either.many games just run too hot.seperates the good parts from the ok ones.and the bad show up fast.

100C/212F is boiling water.

Um, good techs don't let these run so hot even 60C. Chips fails more often at that temp because T-junction temp is higher than at the heatsink contact area.

This supply and all pc prox 3600 cooled only 60x60mm cool ventilator. This caps soldered 2-3mm to al cooler with secondary cectifiert diode with temperature 60-65°C. Capxon KM 3300uF/10V 10x25mm 105°C-1000hours , 65°C-16000hours ca 1.8year.
If use Teapo SY 3300uF/10V 10x30mm 105°C-5000hours , 65°C-teoretycali 80000hours 9.1years.

Teapo SJ is not used, because 3300uF/10V Sj 10x30 is not exist.

1. in the supply aplied 3300uF/10V 10mmx25-30mm caps and this type producting only teapo SC 2000h-105C, SY 5000h-105C, Capxon KM 1000h-105Cstandard, GH 6000-105C, g-luxon? and Samxon KM 2000h-105 standard.
best choice Capxon GH and Teapo SY. In our gaming machine is life time 6years, then teapo sy is ok and praktis testing life time minimum 5years in supply al cooler temperature 65C.

Rubycon, Nippon, Panasonic and other quality brands is not producting 3300uF/10V 10x25-30mm with lifetime >2000h-105C, this products minimum 13mm.

Ok Panasonic FC is good caps, but not buy 3300uF/10V 10x25-30mm.
What Teapo types you using? If use Teapo SC - green caps, or lower series , then logicaly blown after 2year.
This type - Teapo SY is higher product this brand , long life and high ripple current in high freqency.

panasonic fc do fine in game psu and monitors.
i have seen some i rebuilt 10 years ago that are still fine.
got a merit megatouch in now that all the teapo in its 2 year old psu are blown up.

Re: PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

in al cooler is temp 60-65C and this caps aplied 2-3mm cooler and temp to caps is 55-60C. This is QET bad construction, low place in the pcb.

100C/212F is boiling water.

Um, good techs don't let these run so hot even 60C. Chips fails more often at that temp because T-junction temp is higher than at the heatsink contact area.

Lifetime doubles for every 10c drop in temp.

BUT:
"Lifetime" in the data tables doesn't mean "Life Span", it's the Endurance Rating which is how many hours they can be ->abused<- ->without<- any of their parameteres [uF, ESR, Leakage, ect] going out of spec.
The number in the data tables is the MINIMUM time you can run them at that temp AND at max rated voltage WITH max ripple applied [all at the same time] WITHOUT any ill effects.
-
No cap manufacturer I know of makes a claim about actual Life Span.

Re: PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

Yes if in the temp 105C 5000h, then 95c -5000x2, 85C 10000x2, 75C 20000x2 and 65C 40000x2. 80000h - 3333days - 9.1 years in 65celsia in nontstop function teoreticaly without higher voltage.
This switching power suply in 5V line used double schotky rectifier MBR2045CT and 2x caps 3300uF/10V. Level impulse voltage after rectifing is cca 8V. In praktis if use new original supply with using caps CapXon KM standard multipurpose caps smile size 10x25 1000h/105C , after cca 1.5 year nonstop power on, first capacitor is blowing and 5V line not stable and PC is sometime restarting.

Re: PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

The CapXon 3300uF/10v are rated for 1100 mA Ripple.
That is probably not enough.
-
The Ripple rating on a cap is similar to the Watt rating on a resister.
It more or less tells you how heavy duty they are.
Caps too low a ripple rating for the application will overheat internally.
-
Try replacing the KM with *Japanese* caps with a better Ripple rating.
Some good choices would be:
Chemicon LXZ [12.5x25mm] - 1910 mA Ripple
Nichicon PW [12.5x25mm] - 1910 mA Ripple
Nichicon PW [12.5x31.5mm] - 2310 mA Ripple
Panasonic FC [12.5x30mm] - 2310 mA Ripple.
- There are many other good choices in that range.

Re: PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

This is super , but 12.5x25-12.5x30 is very big.
In pcb this supply not place for 12.5mm fi, then i use Teapo SY 10x30mm - 1910mA/rms Ripple curent, life 5000h/105C and E.S.R 0.031ohm 100kHz 20C. Look in datasheet Teapo SY www.teapo.com.
Or use Capxon GH 10x30mm -1860mA and 0.07ohm life 5000h/105C Datasheet is site www.capxongroup.com.

Re: PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

I don't think you seem to understand that teapo and capxon, while there are many worse choices, are not good capacitors.

[8832]

Re: PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

All brands producting types low-standard caps and good special caps.
If producer electronic devices using standard caps anything brands, then life time the device is shorting. Special if this device is use in heavy duty.

If diferent parameters in datasheets type low standard Caps Capxon KM versus Teapo SY or Capxon GH, then you understand.

Re: PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

From what we have seen, teapo and capxon fail early and usually not even under stress. A bad electrolytic formula causes them to fail. This is the whole basis of this website and forum.

YOU specified CapXon KM 3300uF/10v in your first post.
CapXon KM 3300uF/10v are 13mm diameter.

If you want this thing to last a while then don't use CapXon or Teapo [or any other non-japanese] capacitors.

- End of story.

Here is why:

[PCBONEZ]

Re: PC Power supply model QQE100 or QQE98 in book PC Protech 8060-motherboard PROX-3600

Those theoretical lifetimes you speak of are based on the chemistry in the capacitor as new.
They do not take into account the effects of impurities in the Aluminum contaminating and changing the Electrolyte.
As such, those theoretical lifetime calculations are VERY inaccurate when it comes to real world situations.
