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.
