Just looked it up, it's the Seasonic M12II 850w bronze. I've got a seasonic X-1250 gold that i meant to use for this build but was going to save it for the next one. I'll have to find the order date but it has been used for at least 2-3 years because i had it on an FX-8320 @ 4.7ghz and one of my Classifieds. But yeah i need to switch them out regardless honestly just because the 1250 was originally intended to be it.

Sounds good and good luck with that. I was just trying to share information / educate folks some on how power supplies work. It can be a tad confusing sometimes, 850W power supplies don't mean 850W max draw @ the wall side.

I appreciate i never really learned how they worked honestly. Just looked at my sig that PSU has been going since November of 14, so maybe a tad old and possibly not enough? I benched one of these cards at 1350/7000 with the voltage tool when i had it with the fx-8320, haven't been able to get near that since i put the SLi rig together.

It's hard to say really, it depends on what capacitors they used when they made the thing and how good of a quality they were. Different manufacturers use different capacitors and some of them hold up against degradation over time better than others that may use cheaper capacitors so.. it's kinda difficult to really know. I just mentioned it because it's one possibility that may effect it. My 1KW that doesn't OC very well today was a refurbished unit sent back to me from SeaSonic after a warranty claim, It never worked quite right like the original did and I just keep it around for basic testing of older computers or stock setups on certain machines.

Here's the review for the M12 II Evo http://www.jonnyguru.com/modules.php...tory6&reid=356

Funny he mentions the only time the fan really gets noticeable and kicks in is on test 5 which is 847w DC/1021w AC. Everytime i've tried to substantially push and anytime i'm benching or running SLi the fan gets pretty damn loud. Granted it's not a definitive test. I'm going to put the wattman on and hit up firestrike tonight.

OK. Anyone know why the first page (and all its links) are inaccessible?

Short of that, I managed to find the skyn3t BIOS I was after on a Polish website:
http://forum.benchmark.pl/topic/1109...ios-y-gtx-780/

But does anyone have a link to the EZ3Flash tool?

[EDIT]: Scratch all of the above. Turns out it was just OCN's "Enhanced Mobile View" causing the first page to show completely blank. Other pages work fine. Go figure!

Come on OCN - fix this nonsense.

Why would you flash any other bios other than what came with your card? We have all the editing tools for years now. Just post your bios and describe what you want done to it and either I or someone else will edit it for you. It's much safer to edit the original bios for your card and it's quite dangerous to ever flash any other bios to your card for any reason.

Thanks for your response.

I know that BIOS editing tools for the Kepler series have been around since the release of GTX 780 but these weren't without their own problems.

The skyn3t BIOSes have been available since the start of this thread and successfully used by many users. They edit at a deeper level than Kepler BIOS Tweaker can achieve. Specifically, they disable GPU Boost 2.0 and allow a higher power target, enabling higher stable overclocks. You would need to research the earliest posts in this now 2500 page thread (particularly skyn3t's and OccamRazor's posts) for details.

I myself successfully used skyn3t's BIOS for my own water-cooled GTX 780 cards back in the day (running GTX 1080Ti now).

This request obviously wasn't for myself but for a nephew who has a pair of EVGA reference cards in SLI that he wants to get more out of.

Having said all that, I welcome your offer and will happily post his GPU BIOS when I find the time to work on them.

I did not know any of this. I was under the impression we can easily disable the power limits in kepler bios editor by just setting some high amount the card will never be able to reach (no matter how far you overclock it) like 600 watts, and then just flash it. Also, you never want to completely disable boost. You generally want to just raise the boost clock higher. But, I've had problems with my EVGA classified GTX 780 not applying the voltage I specify in kepler bios tuner so maybe the program doesn't tune everything it's supposed to. It does seem to at least disable power limits though.
