Stuck on PSU

[Dibbley247]

Hi.

I'm stuck on choosing a PSU?

The components I've chosen so far are:

I7 8700k
Gtx 1080ti - not sure exactly which type yet
Auros gaming 7 board
Nzxt x62
3 large fans at bottom of case to pull up fresh air
2 X 8gb ram (RGB) and may increase to another 2 later.

Not sure on a disk drive yet.

Then the usual peripherals, plus steering wheel.

1 X m.2 drive
1 X SSD
1 X HDD

Is there anything else I'm missing on this, or any recommendations to change something?
I've done a mid range build few years ago, so trying to go big this time.

Also, being in the UK, is it worth waiting for black Friday/cyber Monday?

I'm not a fan of waiting until possible sales that may or may not happen.

This is a good choice right now.

I would suggest a 650 Watt EVGA G3 Supernova or Seasonic Focus. The GTX 1080 Ti has a system requirement of 600 watts.

When you see things like - this card recommends 600w PSU. What is that taking into consideration for other things on your build?

 

[volkgren]

Yes, 600W estimates the whole system and means 600W PSU should be enough.

As above, the graphics card is by far the biggest power draw in the PC. So system power requirements are based on that, but they do include powering the rest of the system.
