The Powerman cometh.......without power!

[everell]

Here is a Powerman model IP-P350DQ3-2 rated at 350 watts. It has the 80 PLUS sticker, and has APFC. The 5vsb circuit uses a TNY276 chip - a vast improvement over the two transistor design. It uses the CM6800 chip for PWM and APFC. It has TWO mains capacitors in parallel, each OST 150 uF at 400 volts. As can be seen from the pictures, one has "blown its top". The fuse is not blown, and so far I have not found any shorted silicon. The layout looks just like a Fortron. Even the transformers have DASH written on them. I wonder if the OEM is Fortron?

Powerman indeed uses FSP.

Re: The Powerman cometh.......without power!

I recall reading somewhere that Inwin, for their Powerman brand, had stopped using FSP and changed to building the brand inhouse

Re: The Powerman cometh.......without power!

I just removed the one bad capacitor and powered up the psu. The Powerman now delivers power. Only using one HDD and one CDROM as a load. Before putting this psu back in service, I will need to replace the blown capacitor.

Looks like every capacitor in this thing is OST.

Re: The Powerman cometh.......without power!

At work, we use 400W In Win Power Man IP-S400CQ2-0 PSUs for both repairs and new builds. I load tested one and it did 500W (although the ripple was a bit high on the 5vsb). The ones we use are exactly like the one pictured below. I'm pretty sure that all new Power Man PSUs are made by In Win, not FSP. You can tell because there are no "SPI" markings and the heat sinks actually have fins (not like new FSP Builds).
