Hi I have the HP 290 G1 MT business PC, it comes with a 180w psu but I have seen there is a option of 310w psu but I'm struggling to find one of these anywhere. Any help in directing me to one of these if possible would be greatly appreciated.

There is an indication that your PC is the same as the HP 280 G3 Microtower Business PC.
See this page and search in there for Power Supply:
https://support.hp.com/us-en/product/hp-290-g1-microtower-pc/16665152/document/c05519863
I'd go search under the second name too.
