Cap help with Digikey

[Aalelan]

Hey guys, I have not been on here in forever but i'm in need of help.. I've done one personal recap of a test machine here at the house and its been working great.. Now my friend at work brings in her Antec TB 480 (i thinks what it is called) and I take a look in it.. I see all kind of crusty on top of some very bulged caps

I want to try to replace them for him and he didn't mind me trying for him.. Trouble is I was going to get some good replacements for him and not just the recycled crap I had been playing/testing with.. However the Digikey site dumbfounds me! I cant find anything (i know i'm just not searching right)

But here are the ones I need to replace.

3300mf 10v 105c 10mm x 30mm
4700mf 10v 105c 10mm x 35mm
1000mf 10v 105c 10mm x short :p have not taken the board out to see its height

All of them that are poofed at Fuhjyyu

Can someone teach me how to search (know that sounds stupid) or cross lookup these on Digikey??

Thanks guys!!

Aaron

Thanks Willawake! I feel like an artard sometimes! I was trying to use there online cap finder and it was just not working for me.. Found what I needed

Thanks again!

4700mf 10v 105c 10mm x 35mm

Do they have caps in the catalog that don't appear in the web locater?

3300uf, 10mm x anything is always hard for me to find. 4700uf, 10mm x whatever just seems that much worse.

Re: Cap help with Digikey

Yeah, I think that is what my problem was I'm moving up to 12.5 and making them fit

But I do have another question as my brain woke up this morning.. most PS i have be inside of have had 16v caps on the secondary side for the +12v and this Antec is using 10v.. Should I stick to the 10v or make them 16v what are the ramifications of doing that?

EDIT:

or maybe I'm on crack I just noticed there are no 16v 4700mf on the Panasonic list..

Is Antec seriously using a 10V cap in a position where 12V flows through??

Or maybe that 10V cap is for 5V and 3.3V currents. I think that there has to be at least one 16V cap in there for the 12V lines somewhere....

Re: Cap help with Digikey

That may be the case stevo1210. I wish I had it here to quaduple check myself now. at least that I what I wrote down twice last night while looking at it at different times. EDIT: I for sure 100% know they are all 10v now..

But the question still stands what harm would be done by making the 3300mf all 16v? I'm going to recap my FPS550 during this order too and it takes 16v 3300mf and it would just simplify my order a bit

Re: Cap help with Digikey

are you sure the 1000uf are 10mm and not 8mm?

[dood]

Re: Cap help with Digikey

Both SamXon and Rubycon have 3300uf caps in a 10mm diameter. You can get either brand from Topcat here on Badcaps.

If the 3300uf caps are currently 10V, you can boost the voltage up to 16V with no problems whatsoever.
I think it would be better to do that if the 10V cap was on the 12V line.

I do that all the time with motherboard caps.... sometimes I have a board that uses 10mm caps (e.g. 1500uf 6.3V 10mm), I use 1500uf 10V caps which are easier to find here and best of all they are exactly 10mm too.

Re: Cap help with Digikey

if that 10v is on the +12 thats why it failed.
somebody goofed loading the machine that inserts the parts.
you can use 16v parts but they are going to be big.
make sure you have room for em.

not 100% now, I really wish I had brought it back in the office with me today. I do know there is plenty of room around that one so it should not be an issue space wise

I had just placed my order before I checked back here, oh well.. but I did order enough of them in 10v to direct replace but also ordered enough in 16v to do that too if I wanted too..


I'll take some pics of it tonight and then a pic of the ones I take out

Re: Cap help with Digikey

Well, there must be some 16v caps in it, simple as that
If there really isn't you will need to take out a DMM and look which of the caps are on +12v and then put 16v rated caps there, else the new caps will fail too...

You can also look at the power cables if you don't have a DMM, yellow is +12v, so just look where the caps connected in circuit with the yellow cables are

There are lists of what sort of capacitors are supposed to be in the Antec Truepower 480w on this site, I think this thread might have the info:

Re: Cap help with Digikey

I find those Antec Truepower 2.0 PSU's particularly difficult to recap. While working on my 430w unit, I found they have 4 4700uf 10mm caps wedged right next to each other. 12.5mm units will not work, been there tried that. Not pretty. Plus, the wires go right over top of 'em, so you may run into problems with taller caps, when you try to put it back together.

Also, my 430w has two 3300uf 16v 10mm caps right behind the group of 4700's.

Just a friendly warning! My advice would be to either find exactly the right size of cap, or go buy a nice FSP unit... or just

Re: Cap help with Digikey

OK, my bad, what i get for trusting my memory and such... Those 10v caps were on the +5v line. They +12v are all Tepo that I may go ahead and replace too even though they don't "look" bad.

Caps should be here Wednesday from Digikey, I'll let you all know how it went.

Teapo caps do work fine in power supplies. You can ignore Teapos if you want.

Re: Cap help with Digikey

I've seen a few Teapo's fail in Dell PSU's. But that was only after being used for 4+ years. Personally, I'd go ahead and replace 'em.

Re: Cap help with Digikey

All back together and looks good.. it at least powers up a test box here at the house.. also made a new load tester out of a 320W pelt that I can switch between the +12 and +5 rails and held it voltage, all be it only at 11.8 to start with, but it held it. I just wish I would have taken voltage readings before i took the old caps off The guy I'm fixing it for put it on a PS tester (the little led yeah its got power thing) and it said the +12 was low so not sure if this is better or the same..

Thanks for the help guys!! Oh and next time I think I will order from Badcaps as the 12.5mm to replace 10mm was a very tight fit

Re: Cap help with Digikey

It is may be cross loading, just put a load at the 3.3v & 5v rail and the 12v should ramp up.
