The list of components i've compiled is as follows:
-A corsair 4000D airflow case
-Ryzen 5 3600 (might be a slight bottleneck, but i have a 3900X, which is basically the same but double the cores and it barely gets any load during gaming)
-BeQuiet Pure Rock 2 cooler
-Corsair Vengeance LPX DDR4 2x8gb 3600mhz
-BeQuiet System Power 9 CM 600W
-ASUS Prime B550-M A
-3060 TI, manufacturer doesn't really matter
-2TB M.2 PCIe 4.0 SSD (haven't decided on a manufacturer yet, but likely to be crucial, corsair or WD)
for context, she's going to be using a 1440p 144hz monitor and she's planning to play games like Warzone or some of the newer CoD games
i have built multiple PCs roughly in this region of performance before, and they've run great so far.
appreciate any suggestions!
The theory is cheap PSUs don't always have the same guardrails against surging during a failure, or external power event. You don't want your power supply to take your motherboard/CPU/GPU with it when it dies.
