Do i need multiple 12v rails?

[Clayton R.]

I was wondering if i needed to have multiple 12v rails on my PSU if i am running a Kingpin 980. And would i need them to run a 980 from strix also?

No

[Shroomster]

No, you don't.

No. Multiple rails are only needed when you're running multiple, incredibly high-draw graphics cards, and even then you need really beefy rails to handle the power.

Kingpin 980 is still an efficient card, way more efficient than a Sapphire 290X. Running it off of one rail isn't a problem.

Nah

No, in most cases it's actually better to have a single rail.

I plan on getting a RM850 watt corsair PSU to add to my build. I currently have a CX600 watt that I'm using. I heard people over at microcenter (MD Rockville store) say it's the best one to use for overclocking because it has an extra 12v rail to it. Currently my CPU is a FX8370 OC'd to 4.5GHz and I want to push it past that because my little 600watt PSU won't let me push it farther since I'm running dual ASUS R9 270's. Also I was wondering if it'll fit in my case which is a corsair carbide 300r and its a huge and roomy case inside it.

It doesn't matter whether you have a single rail or multi-rail. It will power it the same either way. The difference is that single rail will allow you to pull any amount of power through a single connector that the 12V is capable of, while multi-rail will limit currents virtually being pull through a certain connector. This is a safety feature.

The RM850 is a single rail PSU just like the CX600.
