Well, if it's a fake choke, there wouldn't be much copper wire for your friend to reuse.

Yes, Allied is indeed Solytech's high-end line, with the others as you described. I was just joking with you that you called Allied a high-end PSU. Really in the grand scheme of things, Allied PSUs are pretty mediocre compared to the whole market.

No idea. First time I see/hear of a burned transformer. Normally the primary transistors pop way before that happens. Would be really interesting to desolder it and take it apart. Perhaps a short developed on the output side windings (high-current side).

Probably, I've never seen anything like that, when I saw it I was stunned.
Thank you

He did find some copper wire inside. Ah well, I couldn't reuse the PFC either, as I couldn't screw it to the new casing. Plus, it was blocking airflow.

The fact is that this source ERL39 burned the coil, how is this possible? I had never seen anything like it.
What Hardware was used?
My guess would be newer higher end stuff like a 1070 or maybe even 1080(ti), that causes brutal transients...

That might eventually have killed the Transformer (and possibly other stuff), though the L8 is very high on capacitance on +12V...

Initially it has a gtx 760, with a gigabyte motherboard h77 d3h, 2 SSD, 1 HDD. the processor does not know what it is not specific, but comments that it was freezing by being a few minutes playing, possibly it would not have enough power and I just burn it, as you say. A if the psu must be wrong, or exceeded its capacity.
Now the owner bought a 750w seasonic focus and all the problems were solved.
(sorry my bad english)
Bye thank you

I doubt the transients killed the traffo. Yes, all new hardware has really harsh transients between idle and full load, but most cards typically go through their throttle steps fairly smoothly with the load. And either way, hard transients can only make a PSU unstable, possibly loose regulation and shut off.

Yes, PPFC coils always block a bit more airflow. Still 100% worthwhile installing, though.

Well, as I said, I reused the AC filtering PCB from a Enermax, and that should be more than enough, given the main PSU PCB has complete filtering as well.

What does the filtering board has in common with harmonics?
