OST Capacitors
Hi how are you. I have a Question is the OST capacitors still bad today. Did the company start to make quality capacitors now. Because i bought a power supply brand Pc Power and Cooling Silencer 750Watt Quad. I saw it has a OST capacitor by looking through the metal and Chemicon Capacitors. Thanks

Re: OST Capacitors
Welcome Jatt500.
Not sure if today OSTs are more reliable than 6-7 years ago caps; however caps life is shortened by high temps and PC P&C are told to run cooler than most psus: perhaps this is the main reason there hasn't been a massive failure of PC P&Cs.
ZandraxHave an happy life. -
Re: OST Capacitors
I had a few words with PC Power & Cooling about them touting all premium grade components, only to find OST, etc, in their PSUs.
I gave up on them entirely. Far to expensive for what you don't get. Like Antec, the most brilliant design is totally wasted when implemented with crappy or marginal components.
I have much better luck with Sparkle ATX350-PN supplies. They have a 120mm fan, cool very well, and seem to be populated with mid-grade caps. At $33 USD (newegg) they are priced right. I rotate PSUs in my client machines every 3 years. Same as disk drives.Comment

Re: OST Capacitors
Well i send the power supply back to newegg. Maybe the replacement will have all Chemi-con capacitors. I only ordered it because it carried all japenese capacitors. I ordered now its a different story in Feb 2008. It had a OST capacitor by looking through the metal at end where the wires come from like 24 pin connecter etc....Comment

Re: OST Capacitors
Seasonic do have Jap Caps....but again not sure if you can say that now ...think they do have a 750W in the range (couldn't quickly find a review)
chances are thought they still do
Here's JG on the 700W M12 HERE
A review of the Corsair 750W HERE
("not" Seasonic this build (I think from memory, still I believe its a good build) but does have jap caps by the looks of it)
you do tend to find that most psu's use what are considered lower grade "brand wise" but thats not to say they wont do a reasonable service life in a well build supply circuit. provided a correct series cap is used for the job.
The supply's ability to get rid of heat will also add to their life
There are some rather Expensive 1000W Psu's that use Teapo's
Another catch is yeah it might have "A" jap cap...as in the 1 Mains one.
its the DC output caps that you really need to look at, they are the ones that get the most brutal treatment in a psu.
cheap shoddy design psu's will destroy any cap but a decent design can last even with somewhat crappy caps...but ideally decent caps are really warranted if you want the longest life out of any decent built supply.
(some Antec's case in point, design ok just bad cap choice recap they are fine)
HTH cheers

Re: OST Capacitors
Retail Seasonic's have jap caps. OEM Seasonic's have OST and others, if mine was any indication. We just had a lengthy thread about that in the PSU section.A man convinced against his will is of the same opinion still.Comment

Re: OST Capacitors
I think i got lucky then.
The only caps i can see in the Silent 610 are brown and have the leters 'KZE' visible. (with the exception of one extra large black cap that has 'Nippon-Chemicon' visible)

Oh, by OEM I meant Seasonic branded OEM units, not the ones they make for other companies.A man convinced against his will is of the same opinion still.Comment

Re: OST Capacitors
I just got the Replacement. It still got a OST capacitor. It dont matter to me now. As there is only one and rest is Nippon Chemi-Con capacitors. The Power Supply is working Stable.Comment

Re: OST Capacitors
this sparkle ( http://www.newegg.com/Product/ShowIm...W+Power+Supply ) seems fairly simillar(better to say 'the same') as fortrons i pickedI had a few words with PC Power & Cooling about them touting all premium grade components, only to find OST, etc, in their PSUs.

all teapo and ost inside.

Re: OST Capacitors
FSP (Fortron-Sparkle) has been using Teapo, OST, Jamicon, etc. for a while. They're mid-grade caps, and it won't hurt to recap them at the outset with Jap caps from the recommended list. Even otherwise, FSP designs are fairly conservative and the caps don't fail that quickly.Comment

Re: OST Capacitors
The Sparkle is an easy recap, and priced right. The 120mm fan does keep the internals quite well cooled.
The next step up for good caps is the Seasonic/Corsair. The price is more than twice the Sparkle. If you figure labor and materials for recapping the Sparkle, the price is about the same. The more expensive PSU are also active PFC.Comment

Hi,
I'm wondering if anybody out there has much knowledge of Samsung Bremen motherboards.
I've got a Samsung R530 which is about 10 years old, over the last 12 months it developed a worsening problem where when asked to do much work it would shut itself down. I had a good idea this was due to overheating which was confirmed by a temperature monitor programme which showed little balls of fire next to the various internal temperature readings. I could also prevent it shutting down if I placed a huge fan running at full speed in front of its air intake!
So I went in pursuit of... -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA... -
I have an old PC Power & Cooling 750w EPS12V SLi power supply with the 80mm fan that is unresponsive except for the 5v Standby.
Green wire has 0.10v on it. Will not start PSU when shorted to ground.
There is an ICE2A0565 running the PSU and a
HY510N 'watchdog'.
Does anyone have schematics or an idea of where to start with this guy.
5VSB is at 5.06v connected to Motherboard. There is a 7805 and a diode running the 5VSB it seems.... -
hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?
iv attached photos of the charger and the board inside for an idea on the type of... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of...
