Now, it's time to present, a beautiful high-quality PSU from the PCCASE brand xD .
Although it has at least one inductor on the line of 12v xD compared to L-LINK.
Although this PSU is very dangerous, it has no overvoltage protection in the 5v line, I put a cable in the 5v line and the wire got incandescent .

That 5V line is almost out of spec too, at 5.21V (5.25V is max for ATX spec).

I'm surprised this unit doesn't have a functioning short-circuit protection. SD6109 PWM chips usually offer OVP and UVP on the three major rails, as well as possibility to implement OPP into the PSU. Perhaps the cables on this PSU are too thin for the short-circuit protection to kick in. I had a Deer / L&C LC-B300ATX that burned out on me like that: it never detected the short-circuit, and one of its drive cables started glowing, lol.

Also, I like the label on that PSU above - particularly how they come up with the total power rating. Apparently, 46.2 Watts (from 3.3V rail) + 100 Watts (from 5V rail) + 192 Watts (12V rail), + 9.6 Watts (-12V rail) + 10 Watts (5VSB rail) is = to 500 Watts?!?

The cables are bad, they are super thin. Surely it's because of that.
it does not make sense the sticker xD.
I do not understand how they can sell PSU with false specifications, it can even be dangerous.
The deer at least the specifications are more realistic, and that what is a junk PSU.

Nowhere on that label does it state that it can do 500 "Watts". Even if they meant Peak Power that would still be around 140% of what you calculated; not a true peak rating. That thing was designed to burn your house down.

I know Codegen was making crap units but that's just sad.

I did not know it was a codegen, now I understand why it is so horrible.

I have another PCCASE that has the typical label of codegen (blue color), 600w mark, this PSU is put some load, and explodes directly .

bye
