Hi

Looking at this psu and notice there are 2 versions

CP-9020180-UK
and
CP-9020200-UK

Does it make a difference which to get?

the CP-9020200-UK seems to not be in stock anywhere and £10-£20 cheaper.
 
It's a refresh. Corsair usually refreshes this line every three years. CP-9020180-UK is the 2018 and CP-9020200-UK is the 2021.

CP-9020200-UK differences:
- New Magnetic Levitation Fan. Should be quieter and longer life.
- Supports new S0 "Modern Standby" spec from MicroSoft for quicker standby/sleep activation and probably some other small benefits with standby.
- Looks slightly different, weighs very slightly less.
- Slightly more efficient, putting it right at the top of 80Plus Gold spec (but they are both Gold).
- In-cable capacitors for even better ripple suppression (cables are a little bulkier because of this, but shouldn't be an issue).

All in all, slight gains all round. The 2018 RMx will still be sold at least for now as a cheaper alternative, although prices can vary. If you find the newer 9020200 in stock and cheaper definitely go for it. Both great units.
