Enermax EG651P-VE FMA

[JEWilson]

This is an old PSU (550W/615W) - over 4 years old.

Tested go/no-go and find +5V out of regulation at 5.3V

Open the PSU case and find;
PCE-TUF reservoir caps in the primary,
PCE-TUL used for the O/P filter caps

I see PCE-TUR are on the bad caps list.
Are the caps in this Enernmax similarly suspect?

Should emphasis nothing looks amiss.

It'a probably about time I recapped this PSU anyway.
In fact, I have another same age with the same condition
on +5V rail as well as +5VSB problem with regulation.

So... would go with Panasonic FCs as I usually do.
Need to check the can sizes first.

Any comments?

Made up a BOM FWIW re - the O/P filtration on this PSU

1 of Black 4700 uF 16 V PCE-TUR 105 deg C - H 32.0 mm x Dia 12 mm is +12.0V rail
1 of Brown 4700 uF 10 V PCE-TUL 105 deg C - H 32.0 mm x Dia 12 mm is +5.0V rail
1 of Brown 3300 uF 10 V PCE-TUL 105 deg C - H 32.0 mm x Dia 10 mm is +5.0V rail
1 of Brown 4700 uF 10 V PCE-TUL 105 deg C - H 32.0 mm x Dia 12 mm is +3.3V rail
1 of Brown 3300 uF 10 V PCE-TUL 105 deg C - H 32.0 mm x Dia 10 mm is +3.3V rail

3 of Black 470 uF 16 V PCE-TUR 105 deg C - H 13.5 mm x Dia 7.5 mm is -12.0V rail
1 of Black 1000 uF 10 V PCE-TUR 105 deg C - H 18.0 mm x Dia 7.5 mm is +5.0VSB rail
1 of Black 100 uF 16 V PCE-TUR 105 deg C - H 10.0 mm x Dia 5.0 mm is -5.0V rail

I may have some problems getting 4700uF 16V @ 12.5mm dia and 3300uF 10V at 10mm dia.

Anybody able to help?

Re: Enermax EG651P-VE FMA

I have the following caps, should be suit for your motherbaord, you can consider.
Samxon RS 3300uF 16V D12.5x35mm
Samxon RS 3300uF 10v D10x30mm

There is no problem to replace with 3300uF 16V D12.5mm instead of 4700uF 16v D12.5mm, i have tried in some power supplys. 4700uF 16v in diameter 12.5mm is custom made by factory, it can't find in the market(i meant good caps brand, not bad caps brand). Please visit my caps database for more details.

Re: Enermax EG651P-VE FMA

I would be interested in the 3300uF 10V Samxon RS @ 10mm dia

What order size is required and how much per items as well as, how
much to get it shipped to Scotland?

Please advise

Appears the +5V reading at 5.3V is correct for this model to an extent.

Let me explain.

I recapped the O.P filter caps entirely in this PSU as above.
I used a go/no-go tester to get rail readouts post recap.

Guess..? the +5V rail still reads 5.3V!

Next, I attached 4 HDDs to the PSU and tested again.
The +5V rail now reads 5.2V.

Ah well... the PSU at over 4 years old was due for a re-cap anyway.

Did not find anything amiss with the removed capacitors as with
venting or bad ESR.
