Which PSU are you using for your X79 EXTREME 9 Motherboard and Why?

Which PSU are you using for your X79 EXTREME 9 Motherboard and Why?

The MOBO has two 12 volt inputs so which would be your suggestions for PSU's?

Can I use a PSU with a single 12 volt rail and plug? What are my options here for a PSU with a wattage rating of 800-1050 range?

I have run with the Corsair AX1200 for a few years now and it has been stable and gave me zero problems,plus you get a 5 yr warranty with it:)

So, you have it connected to an ASROCK x79 Extreme9 motherboard?

No but if your looking to buy a good psu then the corsair will do the job,also they have just brought out braided cable sets in red,blue,black and white if your looking to pimp it up a tad.

Corsair is great however, they are ATX power supplies and the ASrock X79 Extreme 9 Motherboard calls for an EPS PSU. Also, my mobo has 2 12volt input, 12v1=ATX & 12v2=EPS (16+2 power phase) which I believe is one of the reasons this mobo is the #1 OVRCLKR. Corsairs only have 1 12volt rail that delivers high amperes ranging from 50-63amps give or take.

So basically I'm under the impression that I have to use a PSU with two 12v rails in order to acheive a more reliable, smooth and efficient OC.

Will the X79 EXTREME 9 Motherboard even POST with 1 12volt rail plugged in? Curious?

wouldnt say that...ive seen people load an ax1200 up to close to 1400w peak and it still ran perfect.

Here is an explanation of the difference in single rail & multi rail http://www.overclock.net/t/761202/single-rail-vs-multi-rail-explained/0_20

ASrock X79 Extreme 9 is the #1 OVRCLKR, compared to what? Not like it holds any records or anything...

who said th extreme9 is the #1 overclocker? LOL hahahahah ASRock's stupid marketing really goes too far, i feel like calling up the FCC and reporting them, seriously man(just like they tried to report me to Intersil, but intersil didn't do anything, b/c i didn't lie). Digital PWM actually requires a digital PWm for one to market it, X79 asrock has digital PWM(ASRock Z77 doesn't), but they aren't #1 overclocker.

I hear that ASRock's cheif or marketing went to America for marketing school, and he is using western style marketing mixed with TW style marketing.

TW and China style marketing says copy the best design, marketing, hardware, whatever just copy it.
I guess Western Style marketing says market to them as if they are idiots.

So together i guess it means to say you have what your competitors have, but also lie about it if it isn't true.


Anyways 1 thing, any PSU will do, once again ASRock enjoys using different names for certain part specifications, but the 8-pin 12v connector is also called EPS12v, and you only need 1 as you wont be doing any LN2 OCing, you do not need 2, and that is just BS about needing more than 1 for cleaner power, you will be using off both of them, however right after you plug them in it is as if they turn into 1 large 12v input. It only makes sense to plug more than 1 in if you use more power than 1 can provide.

FYi if you aren't going to click FTW's link, then let me say this, Rails are just there to define the trip points for OCP and such protections. All the 12v and in some PSUs even the lower voltages are all derived from a single output. That means all your 12v rails all come from the same 12v output, however if you pull more than the alloted current so if you have 20A rated 12v rail, and you have 5 of them, all 100A is coming from the same source, however if you go over 20A on any of the single rails you will trip the OCP. On a AX1200 the 100A let's say, i forget how much it is but i think it is around there, will still come from the same place it came from on the 5 railed PSU, but if you go over 20A the PSU will not trip any protection, you will have to use upto 100A to trip the protection.

Now the AX1200 is excellent for extreme overclockers, because let's face it with SBe you can pull upwards of 300-400W loading full on the 12v connectors, if you had 20A protection you would trip the PSU's OCP. However if there is an issue with the single rail, it will have to go to 100A and fry a lot of stuff before it trips the OCP. 100A x 12v is 1200W FYI.
