Xigmatek No Rules Power NRP-VC503

[c_hegge]

It's a middle-of the road solytech build. The explosion was one of the most spectacular I've seen, because all three transistors on the primary side blew.

Great review like always and the YouTube video of the explosion is a nice touch!

This's a solid review. No rules! It's a hint from Xigmatek. It implies what the power supply's gonna act like.

Great review c_hegge.

You forgot the minus in "-12v". Otherwise, great job of blowing it up. Xigmatek has provided some fairly good supplies lately, but those weren't built by good ol' deer.

The standby supply switcher blew too??? That's odd. You'd think only the main switchers would have been destroyed.

Unless the base drive transformer saturated and blew the transistors driving it, which shorted putting it directly across its supply, blowing the unprotected two-transistor self-oscillator. That sort of cascade failure is all I can think of.

By the way, it's an SBL3060PT on +12V, which I think is made by Lite-On.

Either that, or maybe the 5vsb switcher overheated, as the other two were making the heat sink too hot for it. I do agree that it's unusual, though. I've never seen another PSU which blew the 5vsb and main switchers at the same time.

I fixed the rectifier bit

In test 6 you mixed up the voltage and load on -12V and +5VSB.

Fixed.
