Hi, I'm getting my new case tomorrow which is the nzxt h440, and I wanted to know if I should wait until I buy my new power supply to swap everything or wait. I will be getting the new power supply on the 20th, I did order an RM 850 series because of the nice flat cables, and the fan that shuts itself off until it gets a heavy load. I also order 4 noctua NF-F12 fans with a h100i rad. Please no advice on components, they will just be ignored. I just would like to know if I should swap everything over as soon as the case comes, or if I should wait 12 days. I am very used to installing hardware.
