Hi guys, could I trouble you all for some advice please?

Got a Mini ITX system that I want to put into a smaller case, which will mean investing in either a SFX or a small ATX PSU (150mm limit). My specs are:

Ryzen 5 1600 (no overclock)
2 x 8GB Ram (running at 2800MHz)
Radeon Vega 56
3 x 120mm fans
Keyboard/Mouse
USB powered speakers
1 x 10k rpm HDD
1 x SSD
1 Corsair H105 AIO

Punching those specs into various PSU calcs comes back at a usage of approx 450W at 'normal usage' I'm on a tight-ish budget if I do it now and am looking at 550W PSU's.

I currently have a Superflower 650W but is way too big for the smaller case.

Would the 550W be good enough or should I save up for a few months more and get a bigger one?

Thanks a lot.
