What type of PSU is recommended for my PC

[sammiezlag]

I was looking up some PSUs and noticed that it has more to it than just Watts so I got extremely confused... Based on what people told me, I need a 600W~650W to be able to safely overclock both my GPU and CPU but I don't know the difference between each PSU that provides the same amount of wattage.

How much difference do "Amps" make and is 550W enough or should I go for 600w or 650w?
Notice I might upgrade my graphics card to something equivalent to a 1070 or 1070 ti in a year perhaps.

Specs:

CPU: Ryzen 2700x [Stock Cooler]
Motherboard: MSI x370 Gaming Plus
GPU: MSI Gaming RX 480 4GB
RAM: 2x 8GB G.Skill Sniper 3000
Hard Disks: 2x WD HDD, 1x SSD 120GB
Fans: 3x 120m

My current PSU is the Cooler Master 500w that came with the k380 CM case.
Nothing is overclocked at the moment and the PC is running just fine.

the power supply you have inside will probably be fine, there is a difference on build quality and rating, 600 watts will give you more headroom for future upgrades

Alright, change in plans.

Someone I know was able to put his hand on the Antec TP3-650
Is it good? (p.s I don't have money to buy one anytime soon so would this get the job done with overclocking and especially if I upgrade to a better GPU in the future?)
