I have this rig:

Dell T3500 

Xeon w3530@2.8GHz,

4*2GB DDR3 ram

Sapphire Rx 580 nitro+ 8GB (Clocked to 1430).

 

Are these psu good cause they are available and applicable to my budget.

 

-Cooler master mwe gold 650w fully modular

-Antec High Current Gamer 650w 80+ gold fully modular

-Antec Earth watts Pro 650w Gold semi modular.

 

Are these PSU's good? For this rig.

650W too much. CX 550W 2017 is good for wallet.

you can look around for 450-550w here, what do you have inside that range?

Since it's just a 580, unless you think you'll be switching to an RTX 2080 and a 3950x overclocked this is more than enough PSU for your needs, and the price is more friendly than the 650W units you were listing:

If you're ok paying $14 just to get semi-modular, then this is also a good pick: https://pcpartpicker.com/product/t2mxFT/enermax-revolution-xt-650-w-80-gold-certified-semi-modular-atx-power-supply-erx650awt

Rx 580 requires 550w as minimum and running a power supply at its full potential at almost full load won't hurt pc or PSU performance?lifespan?

 

When i used calulator at different websites they all gave me the same answer minimum required psu 523w....

 

And then they added the extra as 33% which makes it 650w

You should read the posts about "how much PSU is enough" so you can dispel your false beliefs in PSU calculators (hint, they're bad).  The stated high PSU requirement by companies that sell graphics cards are to insulate themselves against crap PSU that are falsely rated for higher numbers (all sticker, no quality).  Any quality PSU that is recommended can easily run a 580 and could be as low as 450W and still be completely fine and not "maxed out".
