I remember an LTT video that had it at about 400W with a 6700k

anandtech also shows about 400w with a 4960x, but teh 7700k is more efficent and it depends on the game. You will be fine with a 500w psu 

[Gaurav S Rao]

A system like this:https://pcpartpicker.com/list/f8Rt2R (I know it is overkill parts prices) would be recommended around a 700-∞W PSU by me.

500W is enough for 1080tis in SLI. It's ridiculous how efficient everything is.

Lets Power a bunch of Intel® Xeon Phi™ Coprocessor 7120A's and R9 295X2's with a 200W PSU,so power efficient right that it will be easily powered,right!?!?!?

Don't be ridiculous. You still need a CPU

The Intel® Xeon Phi™ Coprocessor 7120A is a ridiculous 300W 61 Core running at a waaaping 1.24 GHz boosting upto 1.33 GHz

and supports only 16GB Ram? Its so OP that Intel doesnt even have a Recommended customer price (probably $ ∞ now  ) and of course we know what a R9 295x2 is (just the CPU is more than a 200W PSU).Still ridiculous? Yeah GTX 1080 TI and 7700k and 350W under load? Are you all crazy? That also with OC! The recommended (whatever) TDP of just a 1080 TI is like 600W.

 

The Intel® Xeon Phi™ Coprocessor 7120A is a CPU

Intel® Xeon Phi™ Processor 7290

Oh god dammit should have seen this before and that also $3000?

You will be fine with 550W if you don't plan to SLI.

So you pick a supplementary PCIe powered 61 core processor and a dual GPU card from an older generation to show how modern components isn't as power efficient as some people is claiming? Well, I guess the point that a 500w PSU can power a 1080 Ti in SLI is stretching it...

The TDP of the 1080 Ti is 250w while the recommended PSU is 600w with two PEG connectors (one 75w 6-pin and one 150w PEG). The 600w figure is that way to factor in various of system's configuration and power supply quality.

https://www.hardocp.com/article/2017/03/09/nvidia_geforce_gtx_1080_ti_video_card_review/12

 

That review shows that with a system with an i7-6700k @ 4.7GHz has a power draw of 394wAC at the wall during gaming loads. Factoring in power supply inefficiency, the power draw is ~340wDC. A quality 450w PSU can power that system, while a 550w would allow him to comfortably power it with moderate overclocks on the GPU.

The 650w model will be more than plenty

Will you keep your 7700K at stock clocks or will you overclock?

Ehhhh, nah.

http://www.guru3d.com/articles-pages/geforce-gtx-1080-ti-review,7.html

 

Pascal is more power-hungry than Maxwell. You'd want an at least 750W unit for SLI 1080 Tis and if you wanted to power *just* two 1080 Tis a 550W unit would barely be enough.

[STRMfrmXMN]

Whelp, meant regular 1080s, not Tis (as in, the system in the video). Whoops. 

 

Well there goes their marketing scheme

It's more *efficient* if you take FPS/watt into consideration, but it does use more power than its predecessor.

I object. That figure is way far-fetched.

 

My 5930K (stock) + GTX 1080 Ti ROG Strix (stock as well) can pull just over 600 watts spiking on occasion when under Battlefield 4 gaming load. It averages around the 450-550 mark. Need to watch the graphing one point in time to give you more closer figures.

 

Performance-per-watt is there, but overall power consumption hasn't changed much.

You're gonna want to grab a 750 to 850-watt power supply. All of that overclocked is damn sure going to pull a lot of power, and the power supply needs to be up to the task of powering that thing properly to ensure reliability and stability. Never cheap out on a power supply.

 

Brands I'd recommend are Seasonic, EVGA, and Corsair. They all have very good power supplies up their sleeves.

 

Nvidia recommends a minimum power supply size of 600 watts for the GTX 1080 Ti for a typical gaming configuration at stock speeds. Your needs will vary depending on configuration (components and any applicable overclocks)

Let's be honest. A 750-850W power supply is significantly more than OP actually needs... in other words, "overkill". Sure, it make may sense if you either targeting max efficiency or limiting the amount of noise from the fan, but you're overestimating the actual power draw of the components. In reality, the total power draw would be somewhere along 400W... in a worse case torture scenario maybe 450W with everything overclocked. These are numbers from Guru3D and AnandTech... and even so, they typically use a much more power-hungry X-series CPU. 750-850W would be more ideal for two GTX 1080Tis in SLI.

 

If you want proper reliability and stability, then you'd need to look beyond simple wattage numbers and the 3.3V, 5V and 12V outputs. I'm sure you already know this (after all, you've got a AX1200i) but factors such as hold-up time, component and build quality, voltage regulation, ripple suppression etc. all play critical roles in determining a unit's overall quality, and therefore reliability. It's not as if lower wattage power supplies are inherently "less reliable and stable" than higher wattage ones. Never cheap out on a power supply but don't go overboard either.

 

NVIDIA always recommends a higher wattage PSU to essentially "cover their arses"... or to put it more eloquently, eliminate the possibility of insufficient power if something goes wrong with a user's system. Still, that usually means people grab some cheap Corsair VS or EVGA W1 600W unit and call it a day.

Then you'll want to be ready for much more than the initial calculations in this thread. Not sure about how much the GPU will take beyond spec, but the CPU for sure will draw much more when OC'ed to its limits than the amount it draws at stock. We're talking of at least double the wattage a stock CPU will use, or in that ballpark.

Not really when you factor in the OC.

Plus, you want to be in the 40-80% range for efficiency. Drawing 400W from a 450W is bad for efficiency, for PSU temperatures... for everything

All PSUs reach peak efficiency somewhere around 60% of their rated capacity, but are pretty close throughout a broader range that still excludes very low and very high percentages. Hence, getting a 1200W PSU would be a waste of electricity, but so would be getting a 500W - and in that case it will run hotter too.

Again, if targeting max efficiency and limiting the noise from the fan is a must, then getting a power supply that has a peak efficiency at a specific mode may make sense... But again, quality should always be a priority over a higher wattage unit... that is the factor that determines the longevity and reliability of a unit and potentially the whole system.

 

Heat isn't necessarily a huge con. Modern units last a long time and more often than not, they will become obsolete before the heat actually starts to take a toll. So unless electricity costs are a huge deal where you live, there's nothing wrong with getting a proper 550W unit to power this rig. It's more than enough power and if it's a good quality unit, it's reliable.

Sure, it's an "other things equal" statement. And often you don't need to spend mroe to get the ideal wattage (I mean, sure, if we're talking 1500W vs 400W, same quality, there's going to be a huge price gap  But within a reasonable range, not so much).

At the end of the day, I was addressing the question "how many W do I need for this system", not "how much build quality can I  give up for moar wattz"  

(I also think this forum sometimes exaggerates in terms of how high the bar is for "good quality PSU", but that's a different story)

Heat isn't just bad for the PSU itself: the PSU will be inside a case, together with other components. There is no reason to generate unnecessary additional heat.

Of course, it's always possible to run a PSU to its limits, at high temperatures, and then blame "poor quality" when things turn out wrong...
