Corsair AX860 for 4770K and GTX 780 Ti SLI

post #1 of 118
Thread Starter 
Hey everyone,

I know....I know....another "Will this PSU do this?" thread.

The system:
4770K
Maximus Formula VI
x2 Reference GTX 780 Ti
x2 SSD
A couple fans and assorted case tinsel

The reason I decided to post it up is because searching brought me to some varied responses. According to some information, I'm just fine. According to others, I'm asking for it.

I do not plan to overclock/overvolt the 780's
I do wish to overclock the CPU to the limit a well-ventilated H105 can accommodate

There's a chance down the road I might get back into watercooling so it may be worth factoring in a single D5 or similar.

What is the OCN opinion?

Thanks!

If you're not going to overvolt the 780Tis, then who ever told you it's not enough is misinformed.
You can even get away with some OC'ing on them.

To clarify, each 780Ti at stock speeds and under 100% load will consume less than 260w. (Source)
4770K will consume less than 80w under 100% load at stock speeds.

If the CPU + GPUs are under 100% load at the same time (which is rare unless you're folding on both...etc), your peak power consumption will be less than 620 Watts. It will be even lower in gaming.

Quality PSUs (like yours) can deliver their maximum rated output 24/7 for years without a hitch.

So you have room to OC the CPU to the gills and a mild OC on the 780Tis as long as you don't overvolt them.

I have Seasonic version of this PSU, but not exactly the same...with 860W PSU you only have 100-150W overhead, if that.


eXXon, you are misinformed. My 780 TI's, each exceed TDP by a large margin, at stock. Near 285W per card, actually. I hit the 106% TDP limit (which gives the 265W figure, now 260W) just playing games on a single monitor.

Tri-monitor, I hit 300-320W per card. And yes, the built-in boost controls will clock the cards down...but they still hit that power consumption on peak.

I see you have 780..780 Ti is COMPLETELY different. I have both cards in multiples.


So, 300W/card, plus 130-to-150E for CPU, plus 30-50W for board, + drives, fans, etc...850W PSU is not enough for high-end dual card rig. Over time as PSU wears, it will not be able to provide all that power, and is likely the first component to die in such a build. Never build at the edge of a PSUs capabilities.

NiceGuy....

I have 780 ti sli and HAD a corsair AX 860.....THREE OF THEM TO BE EXACT

People here on OCN that SWEAR they know PSU measurements have VICIOUSLY argued with me that the AX 860 was "more than enough even for overclocking"

WELL IT'S NOT!!...maybe you can get by at absolutely stock 780 ti 980mhz boost, but most 780 ti's boost more than this and I've had my AX860('s) shutdown after long hours of gaming AT STOCK and your gonna be running close to max anyway which is a NO-NO

After all my troubles I finally had to shell out for a 1200 watt and I have no issues now

Have your exact same setup except a maxmius hero and 1 more ssd

An AX860 shutting down with a dual card setup? Hmm.... not saying I don't believe you, but that doesn't seem right if they are not over volted. Do you have like 8 mechanical drives with a full water cooling solution?
post #6 of 118
LOL even 750w could be enough for gaming tongue.gif. Total system power draw below. Furmark is the worse case scenario. I don't know what these guys up there are doing with their systems to have it shut down using an 860w psu (Maybe a cheepo would, but a good would shouldn't)

You've got a 95w CPU plus two GPUs that pull well in the order of 280w a piece. Now factor in the motherboard and all of the other components combined. 860w is pushing it. I would just go with a 1Kw unit and be done with it.

860 watts is more then enough if you are not going to overvolt it or go nuts with OC

But the EVGA SuperNova G2 750/850/1000 or the SuperNova P2 or the Cooler Master V850/1000 are better options then a Corsair AX

He does not plan on OC'ing the GPU's (although he can). Speaking from experience, I had a PC power cooling MKV 750W 80 plus silver PSU that powered a 3770k at 4.9Ghz (1.420v), x2 770's @ 1385Mhz/2004Mhz (1.340mv), 2400Mhz 16gb RAM (1.65v). 2 HDD's, 1 256GB SSD, 6 fans, 1 fan controller, and 1 asus DVD Drive.

I didn't "shut down" while benchmarking... rolleyes.gif The OP would be just fine on a 860W PSU, you guys can stop with the "You're pushing it" comments. He's not pushing anything at stock...

Furthermore, 280w x 2 = 560w. 95w (though a 4770k uses around 107w 100 loaded at "stock" due to turbo) added on is only 655 - 670w range. if you think a motherboard, hard drive/SSD/ram and some fans can draw enough to where it would be "pushing it" on an 860w psu then you've got the consumption figures for those components way, way off.
