Anyone tried $40 420watt power supplies @...?

[Evoluter]

Has anyone had any experience with these $40 power supplies i see at Amamax.com, the one is a Tiger Pro 420 and it says it is AMD recommended the other is a Hivision 400 that isn't recommended. Are these things gonna burn out on me and screw up my mobo and components or are they good deals? How is the noise too? Thanks for any experience anyone can share!

I put a brand new $23 400w power supply (SW brand, made in China) in one of my PCs with no problems. Not recommended by AMD or anyone else for that matter. Running well for the past couple of weeks. Works fine with a KA7 that is very picky about power supplies. This board only works with 3 out of 6 different power supplies I have tried but runs fine with this one. 28a on the 3.3v rail and 40a on the 12v rail.
