Which PSU wattage do I need?

[jgustin7b]

So I went in and used a couple of the psu calculators and both said that my load wattage would be at 254 watts. However, one website gave me a link to a 400w psu and another with the same info recommended a 500w psu. So, which one do I exactly need? If you want, my specs are listed below. (And as an FYI, this is a budget gaming build)

CPU: Pentium G4560
CPU Cooler: Deepcool Gammaxx 300 (Primarily for looks, got it on sale)
MOBO: Biostar B250GT5
RAM: 2x4 gb DDR4-2400 GeIL Super Luce
GPU: Nvidia GTX 1050 (Not the Ti)
ODD: A Generic Asus DVD-RW/DVD+RW drive
SSD: 120gb Sandisk SSD Plus
HDD: Seagate Barracuda 500gb at 7.2k RPM

Plus: A 1080p monitor, led mouse and keyboard, and wifi adapter. (I still know what ethernet is).

UPDATE: A third website says a 520w psu

A decent 450W IS A GREAT FIT AND PLENTY OF POWER.

Looking at your profile, you seem to be an expert in terms of PSUs, so thanks for the advice.
Also, nice find on a PSU. Better than the one I was about to buy, so I'll take that.

It's a decent PSU for the price and plenty of power for your build.
