GTX 660 +12v Amp requirement question Tags: Graphics Cards Gtx Power Supplies Brother Graphics Product Last response: December 14, 2012 12:05 AM in Graphics & Displays Share Matorian December 13, 2012 11:09:48 PM Quick question my brother is looking to get a GTX 660 which states it requires a 400w power supply with a minimum of 24a on the 12 v rail. My question is he has 2 12v rails one with 16 amp and one with 18 amp. Does a single 12v have to exceed or match 24a or do you combine the 2? Thats all I need to know wasn't for sure. He has a 500w apevia power supply. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
