Thumbs down What's the worst psu.....?

What's the worst PSU you've ever used?
If you haven't had any bad psu, post a friend's psu.

One of my friends uses this:
http://www.dc-shop.ro/surse/sursa-floston-fl500-500w-l/
He has an I5 quad processor, with 8 gb ram and a 7770 Radeon video card.

Why do people always buy the cheapest psus available??

Probably a Thermaltake Polo 410W I bought back in 2004. It was a real POS, lasted only about 4-5 months or so. Before it destroyed my Asus P4C800E Deluxe mobo (and then died all togheter), it also took out a few hard drives. I went to turn on my rig one day, there was seemingly no reaction, but there was the alarming and unpleasant smell of burnt electronics. When I stupidly pushed the button again, *poof*, the PSU went out. Frantically replaced the PSU with an older working one, but the damage was done. Fortunately everything else (RAM, GPU etc) was ok.

Colorsit "450W", which couldn't handle Athlon XP 2000+ and Ti4200. But hey, it had shiny gold finish and a SATA connector. One.

There was also a 250W no-name POS, which came in a machine with Duron 800 MHz and Riva TNT2 M64. Exploded after I put GF3 Ti200 there, but took nothing with it.

Probably the Leadman LP-6100D, witch was said to be a good PSU at the time (where no one had a clue about Power Supplys). And the 420W Levicom probably...

And I was really hard on a 300W HEC-300LR-PT...
Had to power an Athlon (Single Core AFAIR) and a pair of X1800 cards...

Was this the one you were using? http://cpc.farnell.com/1/1/30135-psu...colors-it.html

They probably meant to call it Colorshit, but got the spelling wrong...

Worst in terms of overall design and sheer gutlessness I've seen is this - http://hardwareinsights.com/wp/the-e...-round-up-2/9/

Worst in terms of in-practice reliability and failure rates is the CWT-made, Fuhjyyu-packed Antecs. You can't beat a 100% failure rate after 3 years. (Then again, with such poor performance out of the box, maybe you could say that the Okia has a 100% DOA rate...)

The worst PSU I've ever used was the one in my Compaq several years back. It had no name on it, and it wasn't ATX compatible. When it blew, it actually caught fire and caused all the lights in the room to start flickering. Almost like they do when the A/C comes on, but continuously.

I had to yell for someone to run to the circuit breaker and turn off the power, and then grab a fire extinguisher.

When it was all said and done, the motherboard appeared undamaged, but I had to replace the outlet my PC was plugged into. It was fried and blackened.

I was thinking of replacing the PSU, but no other PSU I got would work with it. When I went online to investigate, it turned out that the motherboard wasn't AT or ATX compatible, and I would have to pay $120 for a 350W PSU just like the one that had caught fire.

That was when I started building my own computers. I got another Socket 7 motherboard and case, and proceeded to place my optical drive, RAM, hard drive, and CPU into it. Everything worked.

I've never had another PSU do that, though I do keep a fire extinguisher handy just in case.

The worst, in all reality, has to be the Leadman/Powmax that we used to see so much of in the early '00's. Put down HEC, Deer, etc. all you want. Nothing says crap like slapping a 600W sticker on a 150W PSU.
