Help with my Antec SP-400P with PFC

[LLP]

Hello,

My Power Supply stop working.
When I open the was 3 components totally burned resistor R11 , ceramic capacitor C8 and outher ceramic capacitor close to C8 but I can´s see the number.

Can any one tell me the values of this components or can get me the electronic schematics of this power supply?

In the picture it´s possible to see the components position.

Regards

What model? If its a smartpower then it has bad cAps too

Re: Help with my Antec SP-400P with PFC

In the cage box it say´s Model: SP-400P with PFC.

Re: Help with my Antec SP-400P with PFC

does it say smartpower anywhere?

Re: Help with my Antec SP-400P with PFC

just post a couple pics it will be very very helpful

Re: Help with my Antec SP-400P with PFC

Yes, says Smart Power in the cage.

I will try to put some pics tomorow.

Fuhjyyu strikes again!

By the pic, the 2 caps at the top left are blown (5vSTBY), along with the cap under the heatsink to the left of your C8 marking. That resistor is part of that 5vSTBY circuit. It's failure likely indicates that components following it have had a failure also.

Antec PSU's of this genre require a full recap, sans the mains caps, in order to be safe. If you're lucky, you did not blow the motherboard.

Unless you are extremely tight on funds, I would suggest a new PSU. Parts in just caps would run ~$15-$20 with shipping. If you need transistors or other parts, be prepared for several dollars more.

R11 - Unknown value for the resistor. I've checked several threads and my own pics of similar units and that resistor is not used in them. It's marking is on the board, but unpopulated. Most likely a low ohm fusible resistor.

C?? - It's not a cap, but a surge protector/varistor. I think it's marked VZ2 on the board. Again, value unknown as they are covered in black heat shrink tubing in all pics I've seen. Never had a need to open one up for values.

C8 - Is again in an unpopulated position in other similar PSU's I've seen. Are there remnants of it? Leads sticking out of board? If not, do not be concerned about it as it was unused.

Please update your profile with your location.

Cheers & Welcome!

The "SP" in SP-400P = Smart Power.

There was another two letter designation [vice the SP] that was also for "Smart Power" but I don't remember what it was at the moment.

Re: Help with my Antec SP-400P with PFC

Tp for truepower maybe?

Yup

Re: Help with my Antec SP-400P with PFC

The other Smart Power designator was "SL".
Of course it could mean "Short Life"... but it was on Smart Powers.

These are all crap. - All have Fuhjyyu Plague:
Smart Power
Smart Power II
True Power
True Power II
True Power III
True Blue
True Control
~ Probably others too.

Good luck with them!

I was able to fix only 1 of 3 I got for free some months ago...

Note that they can explode in a very nasty way...

LLP, you might wanna take a peek at the thread where i managed to "revive" an SP-500P. I'm 99% sure the PCB's identical. You might find some useful info in there.

I'm happy to report that it's still chugging away nicely and (pretty) quietly in my "media server" / internet gateway, so to speak

i can help you..if you have this sorce that resistant electric is the 100 ohm

Re: Help with my Antec SP-400P with PFC

i have this power suply like you and i find that resistant burned but not the ceramic capacitor..the resistant is the 100 ohm.. mi power suply is in function right now and i change the electrolitic capacitor 2200 u 10v,2200u 6v...
is god
if you want see the pictures with mi power suply but not now..
