Title: Do I even Need powered Risers? Post by: sitefive on February 05, 2014, 12:00:00 AM Its not that they are more expensive, but I dont want to mess with them
planing to run 4X 280x and 1X 5850 card on P8Z68V motherboard with dual 750w PSU setup. Motherboard image here: http://techinstyle.tv/wp-content/uploads/2011/05/P8Z68-V.jpg My motherboard Does have 2X 4pin power connectors, and it has already 3 full pci-x 16 slots so its already designed to handle that kind of load without the need of powered-risers? no? Also Can I use the Pci-e X16 to x1 risers IN the FULL X16 slots or I need to get x16 to x16 raiser? Title: Re: Do I even Need powered Risers?

You have 3x 16x slots, therefore you can use 3x GPU's on risers without having to power them. If you add a 4th card but your motherboard only supports 3x 16x PCI slots, you'll need a powered riser. I run a small farm and have not had a single issue. Title: Re: Do I even Need powered Risers?
