How Much Power Will My Gaming PC Need?

I know I could have used pcpartpicker.com, but it doesn't have a lot of the parts I'm choosing to use in its database.

MOBO: ASRock Z370 Taichi
CPU: i5-8600 OR i7-8700 (not getting unlocked versions because the Taichi supports BCLK overclocking)
GPU: NVIDIA GTX 1070 FE
MEMORY: Patriot Viper 16GB 3600mHz LED OR G.Skill TridentZ 3600mHz
FAN: be quiet! Dark Rock Pro 4

How much power do I need? I plan on overclocking at least a bit. Is there any specific PSU you would recommend? Thanks!

    Need and how much you should get are different questions. It only needs about 350-400 Watts, however, a 600 Watt power supply should be your target. Having a 600 Watt power supply will keep the PSU from being stressed, it will run more efficiently, more quietly, and cooler. It will also extend the life of your PC. Having a 600W will also give you some headroom for upgrades later. My suggestion is that you get a 600 to 650 watt power supply from a reputable brand with at least a bronze rating. That should keep you good on power for a long time.

    Sounds good, that's what I was thinking. Thanks!
  3. As Justin said, get bronze plus 650w psu and you are fine. And i5 8600k is 238 dollars(i know that you will get non k but i cant find price for non k) while i7 is 300 dollars. You can save that 62 dollars and buy gold plus psu
