Thank you as well sir, didn't make that connection

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!

This way looks the affected area...

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.
