Hiper's 2nd PSU on test is a much more high-end affair. Supporting the ATX 2.0 spec with two 12V rails with good current draw for each, the completely braided and very attractive red-coloured unit had no trouble passing the tests that the Low Noise 350W had such big problems with. Voltage rails were nearly completely correct, even under heay load, efficiency was good at all times (especially under modest loads). The Hiper also didn't seem to share the same heat issues that some other 120mm fan PSUs did, the unit not overly hot in any area after testing.
A high-quality, good-looking supply whose only apparent downside is a lack of PEG connectors for recent PCI Express systems with high-end graphics boards.
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.

SSM Technology was another vendor we'd never come across during testing, their power supplies manufactured by Elan Vital Corporation. Its 120mm fan had an integral 3-stage fan controller, although during all testing with it set to '3', it never spun over the speeds of the first setting ('1'), even under heavy load. A PSU with an obvious server bent, the supply passed the full-load tests without fuss, although +12V was nearer +13V by the end, a deviance of around 6% from the norm. Efficiency was above average at all times and it didn't get very hot at all according to the Fluke. Six Molex and two SATA are welcome. A very quiet and overall impressive supply for the server crowd.
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. Server systems due to SSI connector.
