[SOLVED] Is this is a good power supply to purchase

[keshk]

I have check on pcpartpicker and my rig only pulls about 360 Watts. To be on the safe side, wanted to go for something like a 600 Watt PSU.

Looking to get the following. Based on reviews, looks a like a good buy.
https://www.amazon.co.uk/EVGA-WHITE-Power-Supply-100-W1-0600-K3/dp/B01127D0MY/ref=sr_1_8?crid=2BG8F250C1JAT&keywords=corsair+power+supply+550w&qid=1574547532&sprefix=corsair+po,aps,171&sr=8-8&th=1

Or this:

Was recommended on another thread to go for this one instead.

Bit confused as to why a PSU that has lesser watts cost so much more (recommended one more pricy). Could I get some feedback on whether the cheaper one (1st two link) is a good buy or should I be going for the lastone?

Or otherwise looking for recommendation on a PSU around £50 range or lower (can go up to 65-70, preferably not).

Of those three choices, the last one is the best quality option. Wattage is only one factor. The components used and efficiency of the PSU are others, making the Corsair TX550M of these choices.
