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.

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

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!
