"The Antec TruePower Quattro 850W & 1000W PSUs have stylish racing stripes which run all the way around the steel housing and include an 80mm fan. Along with this fan and the many ventilation holes, this PSU will remain cool in almost any environment. Both of these PSUs have lots of power for today's gaming systems. The +3.3V is 25A and the +5V is 30A. Many of today’s high wattage power supplies that are designed for a 2 video card gaming system and therefore have one large single +12V rail, but these PSUs have 4 +12V rails and each rail is 18A. Remember, a single +12V rail is preferred in a multiple video card setup. Watch the video to find out more and check out the bloopers at the end." ~3dGameMan.com
