Re: Antec EarthWatts EA-430 and EA-500 – an easy bad caps fix
I'll do that. I will come back with full details. I intend to compare the extracted capacitors with the replacements used (I have some from the same batch).
Yes. It is a multi-function "transistor testers".
What I have ordered is called: "2018 V1.13 English DIY Mega328 Transistor Tester LCR Diode Capacitance ESR meter PWM Square wave Frequency Signal Generator"....

Re: Antec Earthwatts EA-500 500w PSU
HardwareSecrets (February 18, 2008)
<< This power supply uses a semiconductor thermal sensor, which is very small and installed on the solder side of the printed circuit board, between the transformer and the +12 V rectifiers. This sensor is used to control the fan speed according to the power supply internal temperature. >>

Re: Antec EarthWatts EA-430 and EA-500 – an easy bad caps fix
It is quite weird with that noise that you described.
What I can say about the output capacitors removed is that they are quite ok regarding their values (after 22000 hours, on my PS):
C406 = 1028 uF (+3.3Vout)
C403 = 1025 uF (+5.0Vout)
C504 = 909 uF (+12V1out)
C503 = 916 uF (+12V2out)
So I will not bet that the weird sound is due to those.
Anyway I intend to test all of them more proprely when my multitester with Atmega328 will arrive.

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/85°C.
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...Leave a comment:

Re: Antec EarthWatts EA-430 and EA-500 – an easy bad caps fix
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/+20°C, 3750mA
I made a quick comparation with the one recommended by you:
NCC KZN 3300uF, 16V, 12.5 x 30 mm, 18mΩ/+20°C, 3660mA
So now I am confident that one capacitor...Leave a comment:

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...Leave a comment:
