Closed 580 PSU question Tags: Nvidia Gtx Power Supplies Graphics Last response: November 17, 2010 6:16 PM in Graphics & Displays Share Nubiatem November 17, 2010 3:20:58 PM http://www.newegg.com/Product/Product.aspx?Item=N82E168... this is the PSU I have. I hear that the GTX 580 needs a 40 amp rail to run correctly, however my power supply is rated at only 30 amp per rail. I believe each 6/8 pin connector has its own rail however so with both connectors it should add up to 60 amps correct? Or... will I have to get a new power supply?
