"Considering most high wattage PSUs are very long, the Sigma SP1000C 1000W Power Supply is surprisingly short. So compact it will fit in all cases; included mid-tower, HTPC and SFF cases. It has a gloss paint finish and the housing is steel. They include a 120mm blue LED fan and honeycomb ventilation ensures maximum cooling so the PSU should remain cool in almost any environment. The +3.3V & +5V rails are both 26A. There are four +12V rails and they are all 20A each with a combined power of 70A. Watch the video to find out more..." ~http://www.3dGameMan.com
