Antec PowerCache

Re: Antec PowerCache

Found more Sanyos inside the shroud over the ATX connector. Labeled S.E.93. 220uF at 16V. Same caps I found inside the unit itself on the modular PCB.

Also found out the hard way that this unit does not respond well to being taken apart. The whole PFC section went kapow when I got it back together and hit it with a 1kW load. Too many SMDs around the PFC MOSFET leads - I probably baked a few with the iron getting that sink out of there.

Re: Antec PowerCache

What do you get for painting it pink and putting on purple rhinestones?

an epic fail!

Re: Antec PowerCache

For those interested in pics of what happened after I got it back together:



Third one from the left blew first, the rest followed.



Damage to main filter cap.



If you look closely at the center of the pic, you will see a blown apart SMD transistor and a fried SMD resistor near it. There's another blown SMD transistor on the right side of the pic.

Re: Antec PowerCache

WOW, that had to be one loud pop

is that fixable?

If so I'll buy it from you

(like I need to spend more on power supplies right now)

Re: Antec PowerCache

damn... you sure fried that one.

im sorry but i am going to have to port that to my destroyed power supplies thread. this is the kind of pics i was expecting to find.

Re: Antec PowerCache

Only fixable if you like soldering SMD components with part numbers that got blown off.

Re: Antec PowerCache

Did some quick testing. All of these can be seen in the PCB underside shot.

Q4 - fried
D14 - fried, shorted
R23 - open
R40 - open
Q30 - incredibly, tested good though missing part of the case

Rest of the SMD transistors checked out good.

Q4, D14, and R23 are next to the one PFC transistor that had a lead pulled apart during disassembly. I had repaired it by soldering the lead back together, and the repair looked good, but this is probably where all the fun started. D14 is on that little coil you see in the first shot, and goes back to the PWM control board.

I'm going to say it ain't worth trying to fix. Secondary parts should all be good, so I'll keep it for parts.

Re: Antec PowerCache

BAH!

Bondo, duct tape, and a little buffing...
