Yeah, if you learned the colors for ATX wiring, it's actually just as easy from there. Just look where the cables of each color are soldered and trace it from there (combining visual, and if necessary, continuity tester tracing) to the rectifiers and check the caps by the way

+1

That's how I always do it too. It's trivial, really.

Default Re: Antec EarthWatts EA-430 and EA-500 an easy bad caps fix

After I have read all the info posted here related to Antec EA-500 I decided is time to open my own veteran PS that came with the Antec Sonata III case (somewhere in december 2007).
So, now it has more than 11 years since I bought it and more than 22000 Power-ON hours (based on first HDD that is still in working condition).

What I have discovered inside:
Obviously I found the -12V & +12V OST capacitors swollen and PCB area around Q901 heated.

The power supply didn't cause me any problem so far. But since I planned to increase load by adding a supplementary HDD I said that will not hurt to do some checking&cleaning. Now it seems that I will need to do a full recap.

My question for you all is:
- Do you think it is a good ideea to install two capacitors in paralel on the +12V rail instead of 3300uF/16V?
For example 2x2200uF or 3300uF+1500uF.

Do not worry about space. I intend to remove all components from FAN circuit (Q901, U901, fan connector, etc.) I will use a FAN powered from outside the PS, from MB connector. This way I will have a better control to FAN speed and eliminate one source of heat near those two capacitors.

By the way, replacement capacitors will be Panasonic FM/FR series.
Thank you!

If it is one of these older platforms with only single large cap, I usually replace it with single NCC KZN 3300/16, that one is superior enough to be a good upgrade

On the +12V rail, after the rectifier it is only one big capacitor OST RLX 3300uF/16V then an split to two PI coils each having an OST RLS 1000uF/16V.

I already placed an order for replacement capacitors.
For this one I found:
Panasonic EEUFM1C332L 3300uF, 16V, 12.5 x 35 mm, 12mΩ/+20C, 3750mA

I made a quick comparation with the one recommended by you:
NCC KZN 3300uF, 16V, 12.5 x 30 mm, 18mΩ/+20C, 3660mA

So now I am confident that one capacitor (as designed) will be enough.
Thank you!

You have wrong capacitor, I have custom D1040 mm variant.

If there is full pi filter, than there is no reason for some major changes. I do have 1200/16 D8 caps for some time now though.

I'm pretty sure the 12.5x35 mm 16/3300 Panny FM he selected is not the wrong capacitor for the 12V rail. Should work just fine indeed.

Now those would be real useful for the 16/1000 caps in this unit. I also have a 350W CWT PSU that uses 16/1000 for everything... but that PSU is hardly worth the upgrade to all new caps.

Considering my temporary recap shown on page 1 was with just a single United Chemicon LXZ 16/2200 worked fine (and it hardly has specs anywhere close to the original OST RLX), I'd say you 2x2200 would certainly work. Of course, as behemoth point out... why? There's no need for re-arrangement on the output side, because the 16/3300 OST RLX is 12.5 mm diameter. So finding a proper replacement shouldn't be that hard.

Just be careful that whatever external circuit you use to control the fan doesn't let the PSU overheat. Voltage-wise, running the fan on at least 5V should be its starting point (as that's fairly close to what the original fan circuit outputs for the PSU when cold - actually close to 4.2V, but anyways. )

*EDIT*
Sorry, double post.
But while at it, at lest let me say that I have now also recapped my EA-430 PSUs. Did a few things different on that one, but it still works great. Will post it another day. As for the EA-500... it's been powering my OCed Q6600/GTX560 rig for a few months now. Also, the weird noise I mentioned in post #16 that I thought the big cap fixed - nope, it's still there, and usually much louder when the PSU is cold than when it isn't. In fact, the noise, when PSU is cold, is almost as loud as the fan in the PC it is in (and that PC has considerably loud fans.) What are the chances that some of the 1000 uF OST RLS caps on the 12V rail or 5V and 3.3V rails are bad? Who knows! Could also be the APFC coil being a bit loose. On the EA-430, it was very lose and covered in brown conductive glue. I removed it on that PSU, cleaned the glue, and then put it back in and glued back tightly with silicone. So maybe that made the difference. But on the EA-500, I hardly see any conductive glue on the APFC coil. Ah well... will pull it out probably some sunny day in the summer when it gets too hot in my house to run the Q6600/GTX560 rig.

I did read through it a year or two... or three ago. Probably even bookmarked it somewhere, but forgot where and then forgot about the thread. I do know you got all the PSU caps that are hard to find, though, so I do keep you in mind if anything is needed.

Default Re: Antec EarthWatts EA-430 and EA-500 an easy bad caps fix

Today I succesfully replaced all electrolitic capacitors from my EA-500 PS, with one exception: Hitachi HP3 330uF/400V/85C.

I've made a small drawing with all capacitors and the coresponding number found on PCB.
I also attached a list with the exact Panasonic Part Number that I used as replacement.

Things that deserve to be Noted:
- successfully installed a 3300uF/16V/12.5x35mm into +5VSB rail;
- the first capacitor on - 12V rail is now better than original OST RLS (Panasonic FM 10mm);
- successfully installed 10mm diameter capacitors on 12V1 and 12V2 outputs;
- 3.3V and 5V outputs have now 1500uF/10V/8mm;
- I removed from PCB: Q901, U901 and Fan connector;
- I installed first capacitors on - 12V and +12V slightly tilted in order not to be in direct contact with the big coil that can get quite warm when the PS is running.
- replaced original ADDA fan with Noctua NF-A8 PWM in order to have better control to fan speed and indication. Original fan seems to me that is spining quite slowly when the PS is working. Not to mention about hot spot around Q901.

Momaka, thanks for the advice!
Maybe I will let Noctua Fan run at full speed. I can barely hear it.
