I upgraded for the first time in 6 yrs.. I'm worried.

Hello everyone. I'm new here.

I built my Ryzen 5 2600 paired with the GTX 1650, a cheap a320 motherboard, and an 8x2gb kit of RAM back in 2020. It just gave up on me 2 days ago.

Earlier today, I brought it to the shop to try and get it fixed but ultimately decided against it and upgraded altogether.

My new build:

CPU - RYZEN 5 5600X

MOBO - Gigabyte B550M-K

GPU - RX 9060XT xfx 16gb

SSD - 1tb M.2 T-FORCE

RAM - 16gb DDR 4 (from old unit)

PSU - MSI mag a650BN 80+ bronze (from old unit)

I was surprised with the price but I've been thinking about upgrading for a while.. I bought the CPU and motherboard combo because I want to try gaming in 1440p but now I'm worried that the 16gb of RAM from my old unit wont be enough for me to enjoy it..

Thoughts?
