Title: Few questions about pci risers Post by: pikuchato on February 24, 2014, 05:40:50 AM I did read some information but I just want to make sure I got it right before I actually buy it..
I currently have 2 Sapphire R9 290 21227-00-40G cards mounted on a Gigabyte GA-870A-UD3 mother board. I am going to buy another 2 cards : Sapphire Radeon R9 290 BF4 21227-00-50G. What I understood about pci risers is: 1) For those cards I have to buy risers with electricity. 2) The riser itself provides power only while the data goes thru USB connection (USB 3 is preferred for that reason). 3) The only difference between 1X16 and 16X16 is more power from the motherboard, When buying a PCI riser with electricity connection it doesn't really matter (1X16 or 16X16). Please correct me if I'm wrong, I suspect number 3 :P Those cards will be powered by a different PSU (1 PSU for the system + 2 cards on motherboard and one PSU for the 2 cards with risers). Did I get it right? Thank you ;) Title: Re: Few questions about pci risers Post by: pikuchato on February 24, 2014, 06:28:17 AM please? ::)

I kind of think it depends on the motherboard and a lot of other details. I'll get my risers tomorrow so I'll try to comment.

Anyway I just bought this: http://www.ebay.com/itm/171246370887 Title: Re: Few questions about pci risers Post by: Minerist on March 02, 2014, 11:11:17 PM 1. Yes.
