Cpu. Ryzen 3 2200g £76.50

Gpu. Radeon RX 570 £120 2 free games

Ram. 2 x 8gb 3000mhz corsair vengeance
lpx £66 (could go to 3200mhz for £73)

Mobo. Msi bs450m pro vdh £61

Storage. Tcsunbow 480gb £36

PSU. Evga 500w 80+ £25

Case. Game master centauri red £28

My targets for this build is comfortable at least 60fps med/high quality 1080p gaming and use of various CAD software.

Any opinions taken on board.

You'll be barely brushing past since a system with an RX570 will need an 500W PSU for the entire system.

I mean that's the first time I have heard that throughout my research, however after inputting my components into various wattage checkers including extra lighting, 3 additional fans and they recommend 450w.
I believe getting too much wattage will result in lower efficiency? and for £25 it's a steal

You can get by with 450W with a 570 it’s only a 200W part. The CPU is around 65W.
