Let me see if i got this straight:
You have our own OCN PSU GURU shilka giving you advice and answering to your questions and you are asking them again to a guy that just joined in? (no disrespect intended Mysterion90)
Im just saying this because Shilka KNOWS his job and look at his rep, that must tell you something of his knowledge, i trust ALL his statements and so should YOU! thumb.gif

Thank you, I did see them. the only reason I was asking Mysterion90 was because the had requested that nobody recommend single 12v rail

I read! im sorry.. I wasn't doubting your information at all. I was just wondering what Mysterion90 thought since they were asking not to suggest PSUs with single 12v rails.

I will be going back to Microcenter this weekend to see what I can get.

Of course after all we are human and make mistakes but what makes you a reference is that YOU KNOW and prove constantly YOU DO! thumb.gif
Furthermore you wouldn't have won the prize for the "Most helpful member in OCN" you did along with my Brother skyn3t, if you weren't an outstanding knowledgeable person here at OCN and im sure you are too at your day job! wink.gif

Did you read my answer to misterion? You are always better of with a single rail but if you cant/wont be sure to get a higher amperage per rail PSU and with a good info on the rails to be easier for you to mix rails if needed be! thumb.gif
Check online first which PSUs they have and ask shilka for advice! wink.gif

I have an AsRock Z77 Pro4-M and I love it. I've had zero issues with it, and it overclocks very nicely.

Hello all again!

Seeing all this OC and PSU talks I can't help but wonder..

I have a XFX Core Pro 650W (oem is seasonic iirc and pretty decently rated by the reviewers I trust), but it's still a 650W unit.. I currently run my FX 8350 @ 4305MHz and my 780 @ 1283MHz and my system's as stable as stable can be. Even so, is this too stressful for this unit? If I go for something like a H100i and push the CPU OC a bit, is it likely to go boom?

Asking since I'd rather plan things and get a PSU upgrade first and then the H100i (or similar w/360mm rad) if needed.

Its an S12IIB and unless you are going to voltmod you dont need more wattage

Sure the S12IIB is a bit long in the tooth but its still better then many newer units out there

Unless you are going to voltmod or go SLI you dont need to waste money on getting a better PSU

Great news, will it keep going even if I OC the 8350 a bit higher to the 4.5-4.8 (shouldn't need too high an overvolt) range after the watercooling?

The 780 is using the OCN bios so it runs at 1.212 and I don't think I'll need to bump it up any further in a long, long time. SLI is also something I won't consider for a long time as almost every game runs awesomely well here. The few that don't are CPU bound and the overclock should ease this quite a lot!

I do love this PSU and it still has 3years left on it's warranty so I'll keep it running for as long as I can!

For GK110 OC'ed you need a single rail PSU otherwise you have to mix rails or cant OC at all beyond a certain point! thumb.gif
By the way, how are you running your Dark Power 1000W? Single or Multi rail? You can choose and by default its multi rail with 4 rails: 30/30/45/45A! smile.gif

(Team skyn3t)

Are you sure it works the way you described? I thought it is works like this:

Let's say your GPU needs 50A and you have 2 18A and 2 25A rails. So the 50A would be splitted equally to all the available rails and the output would be the needed 50A. So you have no disadvantage.
You do have the advantage that the OCP will kick in faster with multiple rails, because even before the Current would be exceeded at least one rail would have to be overloaded and the OCP of this rail would say no and the PSU would shut down. This could be a disaster if happens with a single rail one:
http://www.overclock.net/t/944707/why-single-rail-is-not-better-than-multi-rail

I'm running my Dark Power P10 1000W in single rail mode. You are right that is has 2 30A and 2 45A rails, BUT it has a combined output of 83A! I haven't done some benching with 1.3v+ and 1400+ Core with my current PSU because I'm running two cards and I'm having heat problems with the top card. So I have to solve this issue first.

My previous beuqiet E9 680W was perfectly capable of delivering enough juice for 1.36v@1411 and my CPU with 1.3v@4.4Ghz.
And it "only" has two 18A and 2 22A rails but a combined output of 55A and it was doing it's job perfectly fine.smile.gif

I'm totally satisfied with the Extreme 4, no issues, nice utilities and pretty good OC.

Maybe I was a bit harsh saying one should not recommend a single 12v rail PSU. If you don't plan to OC crazy you should be perfectly fine with the one shilka recommended or a Corsair RM 850.
