I currently am gaming on a gtx 1050ti with a ryzen 2600 (normal wraith cooler) on a msi b450 pro-m2 with micron 1x8gb ram at 2133mhz. Storage is a wd blue 1tb 7200rpm which is all housed in a cooler master HAF 912 mid tower with 3 120mm fans. All this stuff would be fine to upgrade but my psu is a cooler master 400w master watt lite which i don't think would give much head room for a possible rtx 2060 upgrade. I would like to play games like rainbow six siege at 144fps 1080p, - I don't really mind if its low to medium graphic settings. Any recommendations on how i should upgrade/ sell and build new, I have extra budget of about £400 to spend.
