An FSP250-60PNA Power Supply with Bad Caps. I will probably re-cap this power supply as soon as i order the replacements. This will be my first Re-Cap so go easy on me.

Re: Fsp250-60pn
List the caps.
- Make / Series / uF / Volts / Diameter / Approximate Length
From that we can find the Ripple and ESR specs.
-
While you are at it make a map of the PCB and mark where all the caps are including their polarity. [Cap Map]
It will come in handy later when you forget what came from where or which side of some cap was negative.
On PSU's it's easier if you draw it life-size.
-
Lacking a tiny inspection mirror. [Which are near impossible to find small enough.]
... For those buggers you can't read the back of take a butter, steak, or exacto knife and polish the 2" of blade nearest the tip up all nice and pretty with some gritty toothpaste. Then use it for a mirror.

Re: Fsp250-60pn
My Capacitor knowledge is limited, but i will try my best. I am not sure how to measure the Capacitors though.
Replacement List:
Jamicon 3300uf 16v
teapo 2200uf 16v
jamicon 330uf 16v
fuhjyyu 1000uf 16 (its a weird size though, slightly thin but taller, but i will just get a standard replacement and mount it on its side.)
Its only 250watt, but its got an acceptable 12v rail amp, so im putting it in a pentium 4 build. Everything else in the power supply looks ok. None of the Capacitors state "Low ESR" so i guess putting a Power Supply rated Cap will be ok.
My soldering skills are acceptable.
I wont be able to get the Caps till next week though.Comment

Re: Fsp250-60pn
That is - Make / uF / Volts.
Still need - Series / Diameter / Approximate Length
... to tell you anything.
- I didn't ask for no reason....
Every Make [Brand] has multiple Series [Models].
The different Series have different specs.
Then even if you have Make / Series / uF / Volts all figured out there can be several different physical sizes which will have different specs because the ESR and Ripple are dependent on the can size [not uF or Volts].
- Also, if your cap is 8mm then a 10mm or a 12.5mm probably won't fit on the board.
You don't need to measure anything, just read them.
They normally won't say Low ESR on them.
That is in the data sheets, which I can't find without a Series name.
Using caps with ESR too far from the original can send the Ripple in PSU's output right through the roof.
IC chips don't work very well [or sometimes at all] with AC Noise in their DC power.
-
None of those are good brands and Fuhjyyu are down right scary.

Re: Fsp250-60pn
Ok.
Jamicon TK 3300uf 10v 30mm x 10mm
Fuhjyyu TNR 1000uf 16v 24mm x 8mm
Jamicon TK 330uf 16v 7mm x 7mm
TEAPO (the capacitor looks like it burnt so i cant read the series) 2200uf 16v 30mm x 10mmComment

What color is the Teapo's sleeve?

Re: Fsp250-60pn
OH GOODIE - ALL custom sizes!
I'll have to guestimate based on the other caps in these series and the can sizes and what is typical in PSU's.
What country are you in?
- So I can suggest parts sources and see if they stock the needed caps.
Will a 12.5mm physically fit where that 3300uF Jamicon TK is?
Will a 12.5mm physically fit where that 2200uF Teapo is?
[Gives more replacement options if it will.]

Re: Fsp250-60pn
Okay that's an old Teapo series FSP used to like.
I'll have to dig through some lists for rebuilds I've done to remember the series name.
Be back in a bit.
Will a 12.5mm physically fit where that 3300uF Jamicon TK is?
Will a 12.5mm physically fit where that 2200uF Teapo is?

Re: Fsp250-60pn
Hi. I will check to see if the capacitors will fit tonight, as I am busy today.
The TEAPO has what looks to be, a pale green sleeving.
I live in the U.K so it might be hard to order here, but im not sure.
Thanks for all of your help, mcdaydavies.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have a 24 volt version of the same type of switching power supply but that one I am relocating to meter module and I might do the same thing with this one but I have to modify an enclosure that is not made for this type of switching power supply in fact I am not sure exactly what type of switching power supply it actually fits because none of one's that I have the screws holes do not line up and not even close but the switching power supply fits in the enclosure
So I have take out the switching power supply board out of its enclosure and drill the hole so that it can be mounted... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
I have bought computer switching power supplies from Electronic Goldmine before and every one of them the capacitors were bloated and or leaking out of the capacitors so I am sure that these are going to be the same way five or six years ago I had bought some 300 and 350 watt computer switching power supply from Electronic Goldmine these are all from FSP brand
Here is the listing for this switching power supply they only had three of them in stock and I bought all three of them

Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.
i know that in linear power supply the noise will be very low comparing to SMPS supply....
