The Classic Question: Is my PSU powerfull enough?

Hey,

I'm upgrading my old rig.

I'm getting / got:
CPU: i7-8700k (planning on OC in the future)
MB: MSI Z370 GAMING M5
GPU: 2 x GTX 970 in SLi (have been OC'ed, planning on doing it again)
HDD: 3 x Seagate 1Tb Raid 0
SSD: 240 Gb Kingston
Fans: 6 x 120 mm with a Fan controller
Devices in usb: 1 External HDD, Mice, Keyboard, Mic, Headset, Controllers.

I've been to at couple of sites where i can calculate the wattage usage of my system.
At some sites i hit 650w and others up to 750w needed.
I've bought a Straight Power CM 10 700W, that isn't here yet.

So my question lies: Is it BIG and BAD and POWERFULL enough for my dreams to be true?

Yes i did research before buying the PSU. But as i keep looking (because of hype) i've ended in question once again.

  1. 700watts should be enough. However you will likely be pushing it a bit with both GPU's and the CPU overclocked.

  2. No. Your dreams will die in a big funeral bonfire.

    So you will suggest going higher?
    maybe like 800 - 850?

    Well if you already bought it I would personally probably use it. Ideally I would want 800watts.

    Hey again,

    I just ended with cancelling the order on the 700W PSU.
    And bought a Corsair RM850x instead.

    Ty for your time good sir!
