Which to choose ?

Hi guys, thought that it's time to upgrade power supply for future proof builds, i want to take such PSU to use it for 10 years and more. And i come up with three psu's:

• Seasonic FOCUS Plus 750 Platinum 132eur,
• corsair rm850x 80 + gold soon will be in stock in local shop, but price still unknown, but should be around 130eur too,
• corsair hx750 80+ platinum 147eur.

My main preference efficiency and and acoustics, i want too be sure that it won't die and wont kill other parts in the future, also waiting for GTX 2080/1180 and 2080 TI/1180 Ti , Or VEGA refresh because i have 4k freesync screen, even though nvidia gpu still will be better option. There is not so big assortment of them in my local are shops. Please give me your opinion guys.
