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!
Depends on your price per kilowatt hour.
A PC pulling 300w with a 600w bronze PSU (~85% efficient) will be pulling ~350w from the wall. With a gold PSU (~90% efficient) will be pulling ~330w from the wall.
So, for every hour of playing, you're saving 20 watt hours. Thats 50 hours of playing to save a single kWh. Assuming a 25 hr gaming week for a moderate player (full time job, gaming after work and on weekends), that would save you 26 kWh a year.
Depending on your energy costs, and how you expect them to change in the future (almost always going to go up), you can probably expect the PSU upgrade to pay for itself in ~3-5 years if you have a moderately high cost per kWh (like 30 cents or more?).
High efficiency PSUs are gonna pay for themselves faster the more you use them. If it's a one time thing for someone that's only going to play 2 hrs a day, bronze is probably the better option (but you still want a quality bronze one from a known good manufacturer). If you're gonna move your PSU in between builds it's more of a decade long purchase and will continue to save you in the long run. It all just depends on the situation.
If you're just building this for a colleague that doesn't play much, give them a quality bronze PSU and (and maybe upgrade it if you can find a quality gold for another $10-15).
