What power supply?

[Kavaton]

Hey guys, I am building a pc soon, however I'm not sure what power supply I need, either an EVGA Supernova G2 650W or the 750W. Im gonna have a i5 6600k OC, 2 GTX 1070's OC and an NZXT Kraken X61. So which one should I get

Get the 650 or smaller. A 550w would be more than enough.

Although 650W may work, 700W is the recommended wattage for 2 1070s so I would get 750W.

You should be fine with 650W.

 

I suggest to get a i7 6700K and an air cooler instead of a i5 6600K with an expensive AIO.

For 2 1070s? It may work, but not good long term. 500W is the recommended wattage for a single 1070.

I'd rather go with this since you have more threads and especially for SLI 1070. Bad enough a 1070 can be bottlenecked by an i5.

I personally wouldn't go any lower than 700 W. Overclocking can add a lot to the power draw, especially with two graphics cards and one CPU being overclocked.

I thought if you overclocked the i5 to around 4.5-4.7 it would remove the chances of a bottleneck

Thanks for the input

1070s actually use more power than 970s so getting a little more power doesn't hurt anyone.

650W is fine but the 750W version would be what I would buy myself.

Even the Intel Core i7-6700K is going to bottleneck in some instances. Unless you're running at infinite FPS, there's something limiting the FPS, and with how much GPUs have improved in the past few years compared to CPUs, the CPU is pretty often the case.

 

If you're planning on playing 4K, you're going to need as much GPU horsepower as possible to reach over 60 FPS, which the Intel Core i5-6600K will work just fine. If you're going for a high refresh rate 1440p, then you need to consider high framerates. The i5-6600K performs very well, but the i7-6700K can make a difference in this regard.
