The Corsair 860 is a perfect psu for your set up.

I have read of people using up to 900W with 2 GTX 980 Ti overclocked with an overclocked cpu as well, I think it was a 4790k (can't remember the frequency though).

 

If you're not going to overclock heavily you should be fine, if you plan to however a 1000W would probably be better. Give it a try with your 860 and see how it goes, if you crash you'll know why.

This is strictly getting information from GPU-Z.

I have 2 Zotac with mod bios which is locked down to 390Watts Power Limits on each card. I look at GPUZ and in the power consumption row, the highest is 90.2%.... so technically speaking one card is using 352watts and two would be 704 just on two cards. Not including CPU, SSD, HDD, PUMPS, and FANS. I am running a 1000w 80+ Bronze PSU.

My cards are running 1544/8000mhz @ 1.255 BIOS locked.

Just want to share this...

looks about the same as far as CPU performance goes. The Skylake definitely cooler. But both GPU is tacked almost to max. so looks like not much of a CPU test when the GPU is doing all the work.

Count me in for this club. Finished initial BIOS mod / OC this past weekend. Just got it setup in F@H and current PPD is about 668K. biggrin.gif

TDP/3D Base Clock: 1101.5 MHz
Boost Clock: 1177.5 MHz
Boost Limit/Max: 1506.5 MHz
Memory Clock: 3901 MHz
Max voltage: 1.274V
Load temp: 50° C

I ran Heaven and Valley for some time this way without any seeing any artifacts; however, I am noticing that while folding the clock rate will drop down to 1101.5 MHz every 7 minutes or so for a few seconds. thinking.gif I'm new to folding so perhaps this is normal. Any thoughts?

Yes, exactly, when replacing the cooler, you should not to forget about appropriate VRM cooling, because those is the module, which is responsible for voltage delivery and taking in an account its "smallness", then the most heated bunch of components on the card itself..

Will it affect the Core temps ? yes, actual DCIII design has connected VRM cooling through the direct plate to the main heatsink, so it is heated not just by the core, but the VRM too, changing the main heatsink will luxury take care of a core cooling, which will be enormous and that big heatsink for the VRM (tohether with a beautifuly high static pressure of the EK's Vardar fans) will be great to cool, if it is even seperate and I do not worry, if the fan will blow through the both of heatsinks (main and VRM heatsink)..I will even add some little heatsinks on the VRAM chips as I know, it is not heating component , but just for sure, it will raise the investment just for the few euros, but it will make me feel "calmer"

Still, I will paint it too with some black matte spray to have it nice, slick and blackish


...

anyways, guys, only solution for uncontrolable voltage drops even at the 68-70°C or so is custom bios? i have tried the force constant voltage through the AB and Kboost tthrough the precision, but no luck...

example - +87mV with AB, till the card will get to 67°C it will stay on 1,230, after that it will drop to 1,212 and then at 80 I think, ut will drop to 1,194V...unstability garanted :/

Voltage is pretty useless on the new GM200 cards. You are better off trying to tackle the temps rather than the voltage drops. You keep the temps below 60 and it won't drop voltage anyway! wink.gif

My voltage is at +30mv on AB and I still can push my cards to 1505, so either lower your voltage or lower your OC to keep the temps reasonable mate smile.gif

Asus strix in default (no OC) works that it will stabilize the temperature at 80-82°C while spinning on ~2000RPM, so only if I would have the fans spinning at 80+%, which is unacceptable, because it is loud as hell..

I am wondering, why is ASUS Strix, better said DCIII design so bad in the way of effectivity of cooling

Hi,

with my new MSI 980Ti and 68,2 ASIC i got 1500Mhz/8000Mhz fully stable at 1,205v but modding bios disabling boost and up power to 380w because if I set the power down to 380w I got Pwr in some games in perfcap.

Is this ok or 380w is too much ? Max temp in I see in games (Assetto Corsa) is 81ºC

Thank you very much
