is my 850w supernova G2 enough

Each 980 ti is probably around 300w overclocked. Judging by here at 3.9 ghz under load a 1600 pulls around 150-155w (need to subtract the 10-15w idle of 1080 from the 166w of 1600). I'd guess 4 ghz would be around 15w more, judging by here. Adding those together gives you about 770w or so. Ya should be fine.

i can oc my cards to the same without adding voltage would that lower power draw just to be safe ?

Yes, why did you add more voltage in the first place?  

[Princess Luna]

While it is enough, I wouldn't call it exactly easy "way more than enough", it is the right PSU for the configuration, not "overkill" at all but right what you should have to power up everything right.

if u dont sure then buy a 1000w psu then

ok cheers, so it is kinda close with the other bits and bobs but should be ok ?

Yeah, should be ok.

Yeah, voltage matters more than frequency for power draw, though max frequency is dependent on voltage. If you can get lower voltages that hahould decrease power draw.

because when i run games that dont support sli my top card boosts too 1560mhz if i dont touch afterburner and it needs the extra to be sable so i leave it at +50 for sli too to save messing around all the time =]

so just out of intrest what would happen if it want enough would the pc just shut down or blow up ? what happens 
im completly satisfied that my psu is ok that btw now =] thanks for the advice

I have used the psu calculators for my system and they all say I need around 600W for my 4.5ghz 6600k and rx480.  I can tell you I have never seen my system pull more than 300W from the wall even when intentionally under 100% load on the graphics and cpu.  Real world I usually run around 260W from the wall when gaming.

If the PSU is good like the G2 it will simply power down with no negative effect to the system.

 

If it is a Chinese power bomb, the resistors might force up too much to try feeding the required power burning themselves what would result in a dead PSU with considerable chances to kill the motherboard as the voltage will get messed up, other components should remain fine.

[MEC-777]

Moved to PSU section.

 

And yes, that specific PSU is more than enough to run your system.

If it was drawing too much power it would just shut off.

 

If it was cheapo horrid quality unit Chinese psu or raidmax psu it would probably blow up  

[HKZeroFive]

It's more than enough, even in a worst-case, unrealistic scenario. In typical workloads, you'll be far from consuming 850W.

 

The symptoms that arise if your power supply cannot power your components are pretty obvious... your games can crash, your system can unexpectedly shut down, 3D performance would be bad... and for crappy power supplies (so not a concern for the G2), they can break or die.

the point of this post was to eliminate the psu from a problem i am having where out of the blu my pc screens all go black and everything is unresponsive and my mobo code show the number 8 which i cant diagnose and have to reboot. 
it passes aida 64 and a r15 render at the same time for as long as i let it run, up to 6 hours is where i called it stable but every now and again poof black screen number 8 on board, its only happened once since i updated my bios tho so im hoping it is something to do with that and i hope the next bios fixes the issue

Considering it's not happening when stress testing yeah probably not psu

330W was probably total system power consumption, not just the GPU.

My estimates:

GPUs = 220 x 2 = 440W

CPU  ~ 130

and 70-80W for motherboard, drives and fans.

Totals to  650 W.

Your system will very rarely use this much power.

980 Ti uses way more than that

Also where on earth does mobo consumes that much power???

 

R5 1600 consumes a bit more

 

 

Just saying your calculations is way off. Look at the graph I posted above

so what watt do you rate my system at ?

hi guys, so i have a 850 watt psu in my system and everything is ok but i feel like i am cutting it awfully close right now,

r5 1600 at 4ghz 1.45 on the vcore

 

2 980tis at 1450 and voltage +50

 

2 ssds and 2 hdds 

 

6 fans

 

and a h110 cooler 

 

could someone help me please

 

 

I estimate that system's gonna be 450-550W but you're safe

[MrJarhead]

For reference a system with 970sli and a 4790k pulls around 550 watts. I'm pretty sure your system won't pull another 350 watts more, I reckon in the 600-700 range.

[MrJarhead]

So I just watched a 980ti sli video and it was pulling 554 watts on crysis 3 with an i7. 

 

850 will be plenty enough.
