“I purchased a rtx 3090. Also upgraded to i9-9900k. Stock 650w PSU seems to handle everything fine. Should I upgrade to 750-850w. If so how hard is it to change psu? Are there any online guides?”

• Hello, We strongly recommend upgrading the PSU, as it gives you more breathing room and ensures that no power is sues will occur. It is not that hard to change a power supply, there are many guides that you can look at online if you do a quick search.
