Bought two of the Deltas, used one with a MSI 6340 sdr board-works fine.
Should have ordered a dozen. These are obviously OEM items, the cable lengths are too weird for retail. And they're obviously very high quality, there's some serious beef in there- the chokes, sinks, capacitors and transistors are very much high end, more along the lines of a 450w unit.
The issues with not starting up because of no current draw on the 3.3v line are related to the low 5v issues on those same boards with some otherwise known good psu's, namely Enermax. It seems to me that any of the overclocking boards that allow i/o voltages higher than 3.3v don't use the 3.3v at all, they derive it from the 5v, causing regulation/startup problems in some psu's. Been a lot of talk on the AthlonMB forums on this issue..... It's not the psu's, it's the boards, particularly some Abit and Epox models.
As I understand it, some P4 boards don't use the 3.3v either....
Even at $30, they're a good buy, if you need the power and have compatible hardware, or know how to use a soldering iron. Definitely not junk, not in the least.
