Question Time to upgrade the PSU?

[g-unit1111]

I'm currently running a Z77 ITX motherboard in my HTPC, and I am planning to upgrade to a Ryzen 2600 next week. I already have all the parts bought, except now I'm currently pondering whether or not I should upgrade the PSU while I'm at it. This system was built in 2015 and at the time the PSU that I'm currently using - which is a Silverstone ST500, was one of the only mini ITX PSUs available. But now that there are far better options, I'm thinking of replacing it with a Seasonic Focus SFX-650 or maybe a Corsair SF600. Is this a good idea or should I keep my existing PSU, or are there any other small form factor PSUs that I should be considering? The case that I have is a Silverstone Raven RVZ-01B that I plan on reusing.

I own the SF600 , great PSU. Had it for a few years now.

I see no reason to upgrade the PSU those SS PSU's got good reviews in their time.
