Question What Wattage PSU Do I need for my Setup?

[jkk45]

Hi guys,

Setup is as follows:

i7 8700k (hoping to have a fair overclock on this, with some mild vcore offset)
Noctua NH-U12S
MSI Amor LGA 1151 GTX 1080 (again hoping to have a fair overclock, perhaps with some mild voltage offset)
Asus Z370-A Prime
2x 8GB Corsair Vengeance DDR4 2666mhz RAM
1x WD Black NVME Drive
2x 7200rpm HDDs
1x SanDisk Ultra II 480GB
2x Case fans (hoping to increase this number perhaps
Numerous powered USB devicies and hubs

I did have an:

XFX Core Edition 650w PSU but it has recently failed, so I need a replacement

What wattage PSU should I am for so that I am able to have fair headroom for overlcocking, but also not overkill so I am not wasting money. Would definitely like modular as well.

I could stick to a decent 650w would do it , here's a "GREAT DEAL" on a 750w.

A good quality 650W unit is what I would recommend, something like the Seasonic Focus Gold (Semi mod but if you get the Plus version it's fully modular.
