Question: I have a silverstone sfx modular 450w power supply which has a single pcie output port pictured here in blue http://www.cowcotland.com/images/news/2012/05/472765_300138103404247_109532382464821_669570_1747553731_o.jpg. The wire which plugs into this port has both a 6 pin and a 6+2 pin pcie connector at the end. I am looking to power an evga sc gtx 760 which required a 6 and an 8 pin power connection. Would I be able to power this card all from this one cable? Here is the link to the psu on the silverstone website. I cant really make much of the information around using both http://www.silverstonetek.com/product.php?pid=342. Here is the evga link to the gpu http://www.evga.com/Products/Product.aspx?pn=02G-P4-2762-KR.
Just think of a 6+2 as a 8pin thats been split its the same thing you use the 6pin pcie and the 6+2 pcie in the video card it will work fine.
Thanks for your reply however I do already understand that. What I was asking is if using both the 6+2 and 6 pin connector from the same cable is a possibility in general and if so then more specifically with the above mentioned psu.
I dont understand the 6+2 ARE on the same cable and you dont get 6+2 and a extra 6pin on one cable.
Its allready listed on the link you posted above for the silverstone sfx psu
1 x 8/6-Pin PCIE connector（400mm）
1 x 6-Pin PCIE connector（400mm / 150mm）
I power my 680 @ 1280mHz with a single 8 pin to 8 + 6 pin cable. Running under ATX spec, my GPU should get 225W (75 from the PCIe slot, 150W from the cable), but it is possible to run a "dirty" rail and get much more than 150W from an 8 pin.
righty ho. ill keep it simple. i HAVE the power supply on me and there is ONE cable with a 6+2 pin and a 6 pin connection branching off at the end (effectively making it either a dual 6 pin or 8 and 6 pin. my question is.....can i use both the 8 pin and 6 pin at the same time or will tehre be too much current going through the single modular output?
cool. whats a dirty rail?
Dirty rail would be running a rail out of ATX spec, delivering more than +12V, for up to a higher wattage to be delivered (generally up to 500W).
A rail is a VRM, if that helps clear some confusion.
