this is just a powmax with a pretty paint job.
something odd in there with the rulycon,jee,and i.q bulging crap.its original too!

Fantastic stuff.Originally posted by kc8adu
Titaninum (sic) too!
Is that nichicon for real, I wonder, being next to a Rulycon? Then again, it is just about the only cap that isn't bulged. -

REAL PC POWER's website is offline, it says temporarily, but I think they will be offline forever!
Another POWMAX re-brand, and is that Nichicon next to that bad Rulycon a real Nichicon, a question that somebody else asked.Last edited by Newbie2; 04-21-2006, 02:26 PM.My gaming PC:

Re: real pc power(powmax)
I don't see the main transformer - so it must be so small crap that it's hidden behind the heatsink.Comment

Indeed. 450 Watts. They're not lying - that's the power it pulls from the wall socket once it malfunctions.Originally posted by RainbowComment

Re: real pc power(powmax)
Well, at least it has the line-side RFI filters. It should be good for 200W after recapping. BTW, the vent on the 3300/16 Nichicon looks slightly suspect - the scoring is too wide and prominent.Comment

Re: real pc power(powmax)
oh.my.god.
where are the pi filter's coil?
pi filter:
yes, it has but input filters is without Cx capacitors. uh-oh.Well, at least it has the line-side RFI filters. It should be good for 200W after recapping. BTW, the vent on the 3300/16 Nichicon looks slightly suspect - the scoring is too wide and prominent.
i usually add one or two 220nF capacitor (type X2, matsushita) to that empty place.
that Nichicon HE looks okay. it sure is a surprise to see them in a realpcpowder psu. or probably kc8 has recapped it one cap when he took the pics ..
(or not?)...
i can see where the 450W number comes from. hmmm...let me sum all the wattage on all that rails including the negative and +5sb ones, and i get,..wait.... 434.3W?
bad math.

Re: real pc power(powmax)
Hmm.... There's a UL logo on there. I never knew any Powmax/Leadman to have a UL and Real PC Power didn't UL it themselves. I wonder what that listing is, if it's legit at all of course.
Rest in peace BFG. You were... a job...Comment

UL logo without any number, isn't it illegal?

Re: real pc power(powmax)
there are a few annoying people on the various forums but no sense to take part of the site down because of them. I am sure that the larger percentage of visitors are highly appreciative of the long hours of work put into the site. I know i certainly am. Fact of life is that the happy people are usually quiet and the retards/flamers make the most noise. Certainly it would be a great loss if jonny stopped doing what are actually the most reliable and quality psu reviews on the net.Comment

Hello All, I have on the bench a couple of PSU's which have some failed Nichicon PL series caps. They didn't "puke" their guts through the top, but instead "diarrhea'ed" corrosive brown electrolyte through the bottom, down the legs and onto the board. On one cap, the electrolyte rotted the cap right off the board leaving 2 little stubs, and also corroded a trace on the foil side.
The PSU's are Power-One MAP series and are ringing-choke topology. The semiconductors have date codes in 1993. The PSU's were used in a commercial application, fan-cooled. They had failed... -
I want to calculate capacitor ESR referring to below guide.
https://forum.digikey.com/t/calculat...-from-tan/2633
I must find out dissipation factor(Tan(δ)) for nichicon lxj series(6.3v 1500uf,25v 1000uf ,10v 2200uf)
I finally found out datasheet which has all series of nichicon capacitor.But unfortunately, It removed old nichicon capacitor.
Is there anyone who still has old nichicon datasheet which has information of LXJ series? -
A few days ago,I destroyed one of my japanese retro game console by pluging it to 220v outlet.
https://www.badcaps.net/forum/troubl...e-been-blew-up
and I finally fixed​ this retro game console by soldering varistor and glass fuse.
But I noticed that When I measure voltage of PSU's 5pin connector, it is 8.80-9.07v, 5.13v,3.40-3.48v,GND,GND instead of its rated voltage of 9v 5v 3v GND GND.

Hi.
BacCaps forum is awesome - thank YOU ALL for sharing knowledge!
This is about DONG YANG PSU BN44-00195A failiure in Samsung 245BPLUS. It started with bang and smoke from the back of LCD. Downloaded diagram BM44-00192A - a bit different but I will use all parts names from this diagram [and real PSU].
BIG CAP CP801 had 315V, on standby pin 5,2V. After shorting S_B ON (through 3,3k ohm resistor) 24V and 5,3V were missing, on CP801 was 312V.
RM801 [real PSU: RM801 - 0,22 ohm 1W] - FAIL
burned, measured 10M ohm.

Hi there!
My friend wants me to help him repair his old-real-vintage strong-hammer machine. Well it's only 90% real as the force applied doesn't lift the weight itself but it is measured and it moves a motor that lifts the weight
I am attaching several pictures of the machine.
It basically has 2 sides, left side has- 2 x 220->12+24v transformers
- 2 relays (1 moves motor UP, other moves motor DOWN)
- IGF and breakers for safety
- Logic board. Receives 24AC and recitifies it into DC. Contains a uC (M80C85)
