Title: Question about how much power to give a powered riser Post by: coinbeast on March 24, 2017, 09:50:37 AM Hi everyone,
I bought these risers, http://holybitcoin.com/product/pci-e-1x-16x-6-pin-powered-usb-riser-card/ I want to know if I can power them with these, but only using one of the two 4 pin molex's. http://www.ebay.com.au/itm/Dual-4-Pin-Molex-to-6-Pin-PCI-E-Graphic-Card-Power-Adaptor-Cable-/172409234482?hash=item2824642432:g:LesAAOSwrklVMOKz In hindsight I should have bought the 4 pin molex risers instead of these 6 pin ones. 6 pins seems a bit overkill to me.

But you cannot connect more than two from a single cable.
