How often do you guys do a preventative recap?

[Pentium4]

I get free psu's all the time. When you guys get a free psu or whatever, and you open it up and find, say, Jamicon, OST, Teapo. Do you guys recap them even if the power supply is working fine and all the caps look good? Or do you wait for some to die?

Re: How often do you guys do a preventative recap?

When I bought a new PSU for my PC, whitin three weeks, it had new caps. I bought a new Acer monitor about one year ago, first thing after removing the packeing, was to re-cap it. I didn't even plug it in first.

that's hilarious in the acer, were they CapXon?

Same here, be it monitor, PS, MB, TV, or any electronic device.

Do you even replace all the tiny caps? I usually leave the ones that don't have a vent stamp

It depends.. I have several decent psus, all of them fully recapped and fan-modded when needed. Now, I also have 3 true-400Watt psus with badcaps that I am going to recap only when/if I need them and some 200-250-300watt that are not worth a recap with Japanese capacitors. Those if they have bulging caps they get used Chinese/Taiwanese caps as a replacement

Good logic Although I have a recapped Allied running 24/7...I guess kind of a waste of good caps but it seems to be doing well and has a Globe Fan

Well, me too! I have recapped that Premier DR-8400BTX, even though it would never do more than 250Watt continuous.

At least I used Teapo at 3.3V and 5V

Dang, nice improvements to that PSU what's it powering?

Re: How often do you guys do a preventative recap?

It used to power a Pentium D 2.66 (dynamic overclocking up to 3.2GHZ), 1.5GB DDR2 Geforce 7600GT, TV Card, Sata HDD, DVD-Rom and DVD-RW, until I got for free a lot of Jou Jye psus 460 and 400W, that I recapped and repaired. Now I use it for testing motherboards.

Re: How often do you guys do a preventative recap?

I preemptively recap almost everything I get. Sometimes I use stuff for a year or so if its brand new, but anything used gets re-capped before I use it (unless it has good caps to start with). Even teapoo go straight in the fire (or maybe to my bench PSU with the + and - reversed).

Nope, it was Lelon...

I replace ALL of them. If they can't figure out how to make a "big" cap, I'am sure they'll fuck up a "small" cap too.

Re: How often do you guys do a preventative recap?

I will recap any thing new that has a switching power supply

If I want to keep it a long time

..... and........

IF this item has know BAD BRAND caps

....... or............

I have never heard of the brand before

Then all of the caps will be replaced

Case in point I just bought a new switching power supply today and two of these brands I have never seen before ALL the caps in this power supply will get replaced

Dang, nice, and it's been powering that for quite a while?

Sounds like a good idea cause bad caps could fail in 6 months or even 2 years. Unfortunately last week when I was recapping a Bestec ATX-300-12Z, most of the caps I had were too big to fit on the secondary. It had OST and Jamicon, so I replaced all the Jamicon's and left the OST. They used Jamicon for the 12V filtering so I'm hoping it lasts a while

I noticed some strange behaviour when running intensive 3D games or benchmarks. That went away when I replaced it with Joy Jye 460W psu.

I blame that on the fake input caps that were yc 330uF 200V but their real capacitance was 220uF...

I don't know. From my experience Jamicon are definitely better than most of the known bad caps. I would put Jamicon on par with OST, Ltec and who knows maybe Teapo.

Re: How often do you guys do a preventative recap?

Jamicon would probably last in low-stress and low-heat situations - they're still going strong on all my Sound Blaster cards. But that's the best you'd do with them, I think.

I've always wondered why small capacitors with inferior aluminum seem to be more prone to failure in PSUs than on motherboards. I've heard some say they're less likely to fail on motherboards because they don't take as much ripple but I always thought they were subject to a much larger surge current on motherboards then in power supplies... but then power supplies get hotter and have arguably less room to dissipate heat so maybe that's worse?

Re: How often do you guys do a preventative recap?

If it works well, I let it be. I don't buy new stuff so I don't do preventative recaps on that. As for old stuff - if I think I will be using it for a while and the caps are really really crappy (i.e. CapXon or Rulycon) or if there is even 1 bulged cap, I will recap most or all of the caps in that device.

Also, like goodpsusearch, I have a bunch of cheapo power supplies that aren't really worth recapping with Japanese capacitors, so I put used-but-not-bulged caps in them. It's good enough for testing.

Also have this L&C PSU which I partially recapped with Japanese caps:

Originally, I was going to replace all of the secondary caps inside with Japanese ones, but then I got lazy and figured it wasn't worth it. Seems very stable and my old Pentium 3 PC is happy with it. 5V rail is dead on 5.00 to 5.01V, as is the 5VSB.
