Hiper's 350W Low Noise model was the first to fail. In the final intermediate testing step before the levels required for a full 350W of output power, efficiency started to fall off quite rapidly. At which point the PSU started to emit a high-frequency buzzing noise. At 63% efficiency and falling, pulling ~518W to make ~330W of output power, I switched it off for safety.
Recommended system: None

FSP's Green Power series is a range of ATX 2.0 supplies with a new internal design free of toxic metals that can't be disposed of safely, with an additional emphasis on higher-than-average efficiency. The aim is to produce a PSU that's environmentally friendly. It passed all tests without a problem, voltage rails weren't out of specification by much, it didn't get too hot due to the 120mm and the promised efficiency was nearly exactly what they claimed.
Connectivity is above average with plenty of 4-pin Molex, 2 SATA and a PCI Express Graphics power connector. Solid and efficient are the buzzwords to tie to the Green Power 400W with it making the full 400W of output power, more than enough for any modern PC system, without fuss or bother. With different connectivity options, such as SSI, it'd make a fine server-class PSU too.
Recommended system: Mid-range to high-end desktop systems based around P4 (including high-speed Prescott), AMD Athlon Socket A and AMD Athlon 64 and Sempron on Socket 754 and Socket 939. Systems where long-term costs are a factor.
