Re: Power supply build quality pictorial. part 2

Here's a big one:
SilverStone ZM1200M (Impervio IPS-1200EP)

PFC board:
390uF 450V x2 Hitachi HU primary side units.
1000uF 16V Chemi-Con KY x2 before +5VSB inductor with 1000uF 16V Chemi-Con after it.
20N60C3 x2 (two parallel sets) for interleaved PFC stage.
STTH15R06D x2 rectifiers for PFC stage.
20A 600V bridge rectifier at AC input.
TOP243Y switching regulator for +5VSB stage.
MBR10100CT rectifier for +5VSB stage.
Delta IEC AC input filter.

PWM board:
2200uF 25V Chemi-Con KZE x6 at +12V output with 1000uF 25V Chemi-Con KY near end of 12V rails.
270uF 16V Chemi-Con polymer units at the input (after inductor) and output of the +3.3V and +5V synchronous switching regulator modules, each having an L6712 IC.
Both modules have 47uF 25V x4 tantalum units at input and 330uF 10V x4 tantalum units at output.
1000uF 25V Chemi-Con KY before inductors connected to +3.3V and +5V regulator modules.
1000uF 16V Chemi-Con KY at +5VSB output.
220uF 35V Chemi-Con KY at -12V regulator input with 100uF 25V Chemi-Con KY after it.
10uF 450V Chemi-Con CLA unit before full-bridge converter.
UCC3895 PWM controller.
PS232S output monitor.
IRFB4410 x8 used as synchronous rectifier for +12V rail.
20N60C3 x4 configured as a full-bridge converter.

Both boards: All other electrolytics are Chemi-Con KY Series - no poor quality electrolytics anywhere.

Re: Power supply build quality pictorial. part 2

Doesn't look like the PS2 used that much power judging by that power supply. The PS3 PSUs are a completely different animal, though. I think I do have 1 somewhere. Will open it when I get to it someday and post pics.

According to the rear of the system, 50W. I also found out it was an SCPH-35002, not a 39002 as I originally posted.

There's not much to the system despite its size, it's all SMT stuff on the main board, the rest is shielding and passive heat sinks. It's basically just a souped up DVD player with a 3D chip.

Re: Power supply build quality pictorial. part 2

If I can rip apart the slimline PS2's power brick I'll post pics. For now, here's the guts two "identical" PlayStation systems (all of 10 Watts)...

Matsushita power supply from an SCPH-7502 PlayStation (date code 9925E1 stamped on solder side). All caps from the same company.

C005: HB 82uF 400V 105°C 9802 (primary)
C102: FC 560uF 25V 105°C 98FB
C103: FC 560uF 25V 105°C 98FB
C104: FBZ 180uF 25V 105°C 982L
C105: FC 330uF 25V 105°C 99MA
C107: SU 1uF 50V 85°C 96FK

Nichicon power supply from another SCPH-7502 PlayStation (date code 99407A stamped next to mainboard connector). All caps from the same company; different PCB layout. This PSU has poly caps on it, but I have seen other Nichicon units with standard electrolytics.

C003: VZ 39uF 400V H9909
C101: PJ c1 560uF 16V (lowercase 'c' with a line over it)
C102: PJ c1 560uF 16V
C103: PF a2 180uF 16V
C104: PF a2 180uF 16V
C105: VR b3 2.2uF 50V
C106: VR Z2 1uF 50V

Re: Power supply build quality pictorial. part 2

japlytic: It is supposedly Impervio, bud made by IS Quasar. Never heard of that.

Re: Power supply build quality pictorial. part 2

Power Win 235W PSU...pulled from a Socket 423 system! Manufactured December, 2000. It actually looks honestly rated.....and I'm AMAZED to see transient filtering and a bridge rectifier on this old thing...The primary caps are CapXon and all the rest of the caps are a brand I've never heard of. Anyone ever heard of Yihcon?


I didn't know Jamicon made fans!!!!!!!!








For a 12 year old Chinese PSU it doesn't look too terrible...

Re: Power supply build quality pictorial. part 2

I am actually more surprised by the Jamicon fan. Is that the crappy-cap maker?

Yep, same font and everything haha

Re: Power supply build quality pictorial. part 2

Jamicon do make fans as well, and they are actually decent. They aren't as good as Delta and SanAce, but they are better than you're average off-brand fan. They are probably on par with Yate Loon

Those aren't polymer.

The cross shaped vent marks are a good give-away.

It's just the can that looks similar.

I'm kinda surprised. It still works just fine, although it is one loud mofo. As in clear the room before your ears bleed loud but not the ball bearing dying kind of sound. As far as I can tell there is no fan controlling sensor on any of the heatsinks so it must just run at full speed all the time.

Re: Power supply build quality pictorial. part 2

From what I can garner, Yihcon is a cheap, Chinese brand of capacitors, maybe (http://www.hongkong-companies.com/yi...-limited-ga2h/, and the "Made in China" text), which doesn't go to my surprise. I doubt Yihcon is any better than Jamicon in terms of capacitors. I wonder if that "Power Win" has OCP or OPP (no surprise if it doesn't with that choice of capacitors). I take it those primaries are 470uF/200v (and 130007 switching transitor(s)?)?

And I kinda can't help but laugh...

"Do not remove this cover. Trained service people only."

Trained service people who are good at hiding bad capacitors?

Not surprised haha. I'm just surprised that none of them are bulging to be honest...and no those CapXon's are 330uf 200V...Pretty sad that they are almost double in size as the PSU I posted in the gutless hall of shame. Those Jpcon's are TINY and say 330uf 200V. Owned by CapXon? Ouch..
Yeah, they don't want you to know what's inside and what should be inside

Funny how the original PlayStation PSU is only 10W, then PS2 is 50W, and PS3 is ~300W? Can't stand it when people tell me newer is more energy-efficient.
Energy efficient my ass.

It's more or less honestly rated IMO. Caps most likely survived because the fan was running at max speed. I have a old, cheap L&C (posted a few pages back) with all of its Jun Fu and CapXon caps still good because it had a powerful fan that ran at full speed.

Yihcon are way worse than Jamicon. They are just re-branded Fuhjyyu caps. I've seen them in a few Key Mouse PSUs before

Man, I'm surprised they're still kicking. I also have a KME power supply from 1999 that is purely CapXon and that little sucker still works.

Re: Power supply build quality pictorial. part 2

Okay, here's a 1999 Deer DR-240ATX (on the PCB) or a Deer LC-250ATX (label). Wondering why it's so clean? No, I did not blow the dust out of it. It's never been turned on.



Jun Fu primary caps, and a mix of PCE-TUR and Jun Fu on the secondary. The input filter coil is made of simple wire. How cheap. At least they included a bridge rectifier.

More PSU/PCB pics to come... the elderly Canon PowerShot A2000IS needs to be charged (yes, that camera is utter garbage indoors but it's better than nothing).

I gutted one just like that. Mine was well used and had bulging caps.

Re: Power supply build quality pictorial. part 2

Man how many designs theay got?? They are almost all crapy but I swear I have seen at least 10 different deer/deer-clones designs.

[Pentium4]

Re: Power supply build quality pictorial. part 2

What do you think this thing could do as it is right now. I want to recap it eventually, all the caps are Jun Fu. I'm thinking this thing could pump out 300W? It has a 135mm fan. Heat sinks are pathetic though.









Probably one of CWT's lowest end designs?
