PSU problems(More inside)

Re: PSU problems(More inside)

Most likely not.

I don't know which CapXon you show as bloated there, but they look like 10x30. The Samwha caps in the picture are General Purpose caps that are only 10x20 with a ripple rating of only 778.

If you're going to place an order with Farnell (Here we call them Newark, other times, they're called "Element14"), you should take a good look at the Panasonic "FK" series through hole capacitors (Prefixed with EEU - the U denotes the through hole variant and not the SMDs) which you will most likely need in your repair.

I've done 2 FSP PSUs now, and I found that the only thing that could match the custom size 10x30 parts were the Panasonic FK (Normally, caps with the same ratings as the original Teapos or OST are 12.5mm - FK are miniaturized in width and FR are miniaturized in height).

In my opinion, you should do a complete re-cap of the whole PSU.

Can you post more pics?

Take those wires out of the way and post all the caps.

Wow so much response in so little time, thanks a lot . I was considering replacing with quality caps too, but i didn't know which ones are good and where could i get them. Anyway im going to replace those 6.3s with the ones i got currently. After replacing im going to look for replacement for those and the GF's, also gonna replace the startup one i think.
Also at the farnell website which caps should i look for? I notice theres bunch of caps made of different material.
Oh and the new caps are on pics. Thanks again
E: I was also considering to buy some broken quality PSU's(Like Antec etc) and salvage capacitors off them. If those caps turn out to be bad i could replace them with what i have and resell it for moneyz, aint got much to lose, those quality psus go for like 2-5€.

Also, the tiny cap in the first pic to the left of the transformer ALWAYS goes bad. It's the startup cap from what I can tell. 25V 100uF

As for the 6.3V 2200uF.. with a bit of ingenuity it is possible to shove a 10mm in there, but only one. You also have to be a bit careful when putting the cover back on then (to not scratch or dent the cap)

Fortrons are generally good PSUs, but their constant crapcap selection in just about any halfway recent model kills them every single time..

Well, that's not gonna work, or at least it won't be cheap as Farnell only has them in the US warehouse and they'll ask for 25 euro (~40$) just to move them to Europe for him.

Pretty much what he can get without spending a ton of money is 1500uF 6.3v Panasonic FR but it's probably too small capacity to be enough: http://ee.farnell.com/panasonic/eeuf...0uf/dp/1800608

Then again, 3.3v is not used that much nowadays and the FR has very good specs.

Replace them with http://ee.farnell.com/nichicon/uhm0j...-3v/dp/1823798 . Spec-wise, they are overkill, but they are they only reliable 2200uF capacitor in 8mm diameter.

Replace all capxons, bulging or not, unless you want to take your power supply apart again in the near future.

The Fortron Epsilon 500w is quite capable and should have no problems powering that video card.
You just got unlucky with the capacitor selection in the power supply... must replace both the Capxon and those with the GF label (known bad series)

Wouldn't hurt replacing those capacitors by the heatsinks with higher hours @ 105c rated caps.

Stores like Radioshack don't do high quality capacitors, only general purpose ones which are not good enough for a power supply.

Since you're in Estonia, try http://ee.farnell.com/capacitors - I'm using them and their UK version of the website and it works great for me.

Stick to quality brands like Nichicon (HM/HN/HZ), United Chemi Con, Rubycon (ZL*), Panasonic (FM/FR/ others) - if you say exactly what's written on those capacitors maybe we can give suggestions.

Alright so i was using my PSU for a while with an lower power card(R5670) and ive switched to gtx 260, which obviously takes more juice. From the start i've had a problem that my PC would only start when it had cooled for like 3-4hours. I consider my current PSU good(Fortron Epsilon 80plus 500W) and it is above GTX 260 limits, ive seen guys running gtx 470,480 off it. So recently i opened my PSU to see where the problem is, i saw quite a few capacitors that were leaking(On pictures). So i ordered a few replacement caps for them. Now i have quite a few questions about it. The capacitors were 6.3V , 2200uF btw.
Could those small capacitors cause the problem(Like 3 failed ones)? Also recently when i started without my graphics card i saw that sometimes the power fluctuates a bit and then PC shuts off. When its running it runs good and with very healthy voltages. My father is licensed electrician so replacing the caps won't be a problem. It's just that he usually works with way higher voltages and different equipment(Workbenches in factories n stuff like that). Are there any special stuff you should know about replacing caps etc?
Sorry for all the grammar mistakes, il try to fix them by morning
Also the leaking capacitors were all the same type, all other stuff seemed fine. And i ordered proper replacement, no need to worry about that, we have something similiar to radioshack in our country.
