What PSU do I need?

[ameisin]

Hi! I'm making my first pc build and I would like to know which PSU should I get. These are the components:

Motherboard: Gigabyte B250M-DS3H
GPU: MSI GTX 1060 GAMING X 6GB GDDR5
CPU: Intel Core i5-7600K 3.8GHz BOX
Fans: 2x front 140mm (the case includes 2x120mm, one for the back and the other one for the top of the case)
RAM: 2x Corsair Vengeance LPX - XMP 2.0 - 4 GB, DDR4, 2133 MHz, C13
Case: Nzxt CA-S340W-B1
HDD: WD Blue 2TB 3.5" SATA 3
Monitor: AOC E2476VWM6 24" LED
Keyboard: AUKEY mechanic keyboard tenkeyless
Mouse: Standard 15£ mouse

These components without the GPU use around 130W.

Now, the GPU says that it uses 120W but recommends a 400W PSU. What does that mean? That it needs a minimum of 120W and uses 400W if needed?

I don't know if I should use a 450W PSU or 550W PSU, and it's important since I would like to get a UPS too, and the price of the UPS changes a lot from 450W to 550W.

PS: If you want to suggest a 140mm fan, please do so. I don't know what should I get.

PS2: I couldn't use any PSU calculator since the GPU specs are far over the limit of the calculators.

IMPORTANT: I'm not going for OC.

Well a good 450W psu Branded will do the job but i recommend you to go for the 550W if its possible so that you can achieve more just in case if you are gonna do more overclocking gonna add more fans and other stuffs like that

Get more power than you need incase you upgrade the video card in the future.

The size of the PSU is not going to affect a UPS it only is going to be putting out the amount of power needed for the PC. A 550 watt PSU does not put out 550 watts unless the PC needs that much power.
