Dual 12V Rails And Overclocking

[asicman]

Those with dual 12V PSUs, what kind of overclocking results are you seeing?

Thanks.

Umm. It shouldn't matters. It's only electricity after all.

Unless upgrading to a new dual rail PSU solves instability issues. My single 12V PC Power & Cooling does just fine with a 34A 12V.

Ya, the rumor I had heard was the dual PSUs weren't overclocking as well.... I've got a 3700+ San Diego that just won't OC over 220x11 on an EPoX 9NPA+Ultra.... FAR less than what it should be achieving. At this point I suspect either the PSU or the CPU itself. I'm about to pull out the DMM and poke around.

I switched from a single rail to dual rail PSU and was able to keep the same OC.

It usually depends on which PSU's you're comparing.

In all honesty dual rail vs single rail....

Apples vs Oranges!

If your single rail wont allow you to over clock or maintain your over clock it truthfully should have nothing to do with dual or single rail anything!!

The bottom line is...get a PSU that can handle more watts....

In fact you might try this PSU......550 watts of smokin power.....

Oh wow! :roll: A 26$ 550W PSU with 24A on the 12V rail. Also made by an unknown company.

Now let's compare that to a Fortron 300W PSU @ 22.99$

You'll notice that the Fortron 300W PSU has 32A on it's combined two 12V rails.

Thank you for saving me the trouble of responding to that post Kensai! :thumbsup:

 

[JEDIYoda]

too funny.........that prior post was all in jest........too funny....

OKIA nows thats a solid name brand if there ever was a name brand.....

BTW the same company that makes Fortron also makes OKIA....heheeee

Taken from another forum -
I just purchased the OKIA 550W Dual Fan Power Supply, I found it for a pretty good price! I switched it out for my old PSU (which was a ANTEC).
For the cost you could not get a better more solidly built PSU!!!
OKIA rules Big Time!

I'm using an Aerocool 550W PSU. Look at how well it performed in this review: http://www.viperlair.com/reviews/cases/other/psu/acoolt550/p2.shtml

 

[Safeway]

Use good PSU, and that OKIA thing isn't.

 

[Bona Fide]

I would look for amperage. If you're overclocking, you need at least 28-30A on the 12V+ rail. Dual-12V gives you some overhead, so you usually drop 10% from whatever the sum of the two rails is.

 

[asicman]

I'm out of ideas. So, this week I plan on testing with a different PSU. I'll buy something locally that can be returned, like the Antec TP-II True 480. It's dual 12V also, but I don't think that's the issue.

this dont matter. any decent 12v rail's not gonna stop u from oc'ing...

 

[rise]

i don't know if its your psu either but at least you got a good one

That's a maximum load (peak) not sustained output. Under normal conditions it's 8A per 12V rail, not 16. 32A @ 12V = 384 watts, simple logic will tell you that's not possible for a 300 watt PSU.
