HWG,
I had a 400W Raidmax PSU nearly burn my house down last year, I was at work when the fire started and the quick actions of a fellow FF contained the fire to one room, plus smoke damage.
What annoyed me the most was the fact that the PSU was being used nowhere near it's output capacity, in-fact it had an old 386 computer running Mandrake Linux on it for my weather station.
I had the idea that bigger was better, when 200W probably would have done the job.
I lost a lot of radio gear in that fire and it turned out upon investigation that the fuse in the PSU was rated at 3 times what it should have been, this was out of the factory.
Also what I found, was that the MCB at the panel had blown, but the PSU (According to my mate) continued to burn "with bright yellow flames and thick acrid smoke exiting the rear fan aperture".
Now, one thing that you guys have to remember, is that brands mean nothing anymore.
We've had parallel importing here for close on 10 years now, this is where cheaply made brand name goods are imported without the consumers awareness, but are sold as the real thing. mad
These goods are made as cheaply as possible and have huge mark-ups once they make it to the retail stores.
All that aside, I really don't see how you can tell the quality of a SMPS based on wieght, maybe I'm missing something here?
