PSU worth replacing caps?

Re: PSU worth replacing caps?

It has only been a few days, international postage usually a week at least.

post across the EU usually is a few days actually.

Turned up today, just going to fit them now.

Sent Friday, received Thursday so just shy of a week. Thank Behemot.

The pop and smoke was probably just one of the caps exploding, not a transistor. Otherwise, the thing probably wouldn't still run.

It looks like you just like having fun disagreeing with people and I could care less. It makes you look rather silly. You do your thing and I'll do mine. If you want to keep putting band aids on cheap junk psu's then that's your business. I've been in electronics longer than you've been born

He wasn't being rude about it, or trying to start anything. Failing caps doesn't mean the power supply was poorly designed. Cheap caps will fail in almost every scenario. The thing that takes the brunt when capacitors fail in the power supply is the attached hardware, not so much the power supply itself.

If other parts in the supply were stressed and end up blowing later, so what? Replace them too, that's what this forum and repair is about... even if it's not economically sensible, chances are you'll learn something from it or remind yourself of something you forgot. Not everyone has years of experience and repairing even a junk PSU is likely still an educationally worthwhile thing for many people.

I agree though that it's maybe not worth the hassle or cost if the PSU is really cheap, but if you can't afford a better one it might make sense to spend a little time to improve a cheap one and use it as long as you are aware of its limitations.

It depends how cheap you're talking of course. Some really are awful, and I wouldn't bother with them either (even brand new), but some budget PSUs aren't too bad, they use tried-and-true designs and seem to be fairly reliable provided they aren't overloaded and the capacitors aren't junk.

Mister, if you can't even tell half decent power supply (and this one is somewhat better than that), than it is good I never got anything from your "electronics" and I hope I never will.

As Dr. House says, you have to deserve to be arrogant. So far you showed nothing but calling every PSU in every thread you posted in a PoS. So I suggest slowing down with that

My point exactly. This is an excellent quality PSU, which was let down solely by the caps - not a piece of junk from the ground up. I DON'T ever recap cheap junk PSUs. (in fact, there are probably quite a few PSUs which I would deem not worth fixing when most others here would fix them)

Re: PSU worth replacing caps?

I woudn't count Topower that much to the 'quality manufacturers'. They are somewhat OKish, sometimes, but not really that great....
Even compared to others from that time (Enhance, Delta and so on)...

Well, the Dark Power P6 (non pro) I tested on the chroma was somewhat OK but had JenPo caps...
The P4 and P5 were worse as they used those Fthings...

I think I have found another person who voted for Obama!

By the way, the Bestec ATX-250 12E (mobo killer) is a great power supply after recap and 5vsb mod (DM311 mod). I am running on one right now.

How it has been the replacement?

Re: PSU worth replacing caps?

Ive only tested it on a PSU tester so far and it seems to be ok. its got a bit of coil whine / buzz in standbye mode but I don't know if that's how its always been.

I'm gonna huck it up to an old sli GTX 470 system which is very power hungry and let it run 6-12 on loads maybe running heaven or something.

Will report back

New capacitors perhaps need a little glue to hold them up to the plate and do not vibrate.

The point is that any glue is not suitable for components, it may affect chemically to the plate.

I planned to use hot glue but only if it is suitable for this use.

If someone could tell me if I can use this glue, I would appreciate it.


Thanks

Re: PSU worth replacing caps?

I don't think hot glue is suitable, I've used some RTV silicone on this to separate capacitors from coils as that's how it was before.

[ep9es]

Re: PSU worth replacing caps?

Thanks for RTV silicone.

I will search it.

[mikay786]

Re: PSU worth replacing caps?

this is the one I used, non corrosive is what you need from what I read. Might not be ideal so hopefully someone else will chirp in

Re: PSU worth replacing caps?

i use UHU or Bostik all-purpose adhesive on pcb's
it dries like plastic and is not acidic or conductive.

[Behemot]

Re: PSU worth replacing caps?

I've been thiking about ordinary bathroom silicone, anybody tried?

[stj]

Re: PSU worth replacing caps?

carefull with that, it comes in 3 types.

acid base, alkaline base, and neutral base.
obviously you want the last one!
