from TechSweden.org managed to get some details on Silverstone's soon to be released 1500W power supply unit. This overkill PSU has enough power to supply any configuration that you can think of and even has support for Multi-CPU servers and all known SLI and Crossfire setups.
The new SST-ST1500 has a full modular design, extra long cables with short kit option for small chassis install and most importantly, it has a total of eight +12V rails with 25A max and 30Amps of peak power. These numbers add a total of 1320W/110A of maximum combined output, and 1440W/120Amps of peak output on +12V rails.
The PSU has single 24-pin MB connector, two 8-pin EPS, four 6-pin and four 8/6-pin PCI-Express connectors, twelve SATA, twelve 4-pin peripheral and four 4-pin floppy connectors. The good thing is that all of these are modular so you can plug in the ones you need, otherwise it would be a big mess with so many cables.
The entire PSU is cooled by a single 135mm ball bearing fan that produces between 19 and 34dBA of noise depending on the speed.
