need some help picking out upgrade parts for my mid range gaming pc that i bought from techfast in 2019. it was bought at around $700 at the time which still sounds like a bargain lol. the PSU shat it self 2 days ago and so I updated the PSU already with a Be Quiet! straight Power 11 750w.
I need help selecting upgrade for RAM and Id love hearing opinions about fitment issues; if any.. with the aftermarket (be quiet! SHADOW ROCK 3 CPU Air Cooler)
CPU: Amd ryzen 5 2600
GPU: Amd Radeon rx580 8GB
RAM: TEAMGROUP Elite DDR4 8GB Single 2400MHz PC4-19200 CL16
MOBO: Micro atx asus prime a320m-k
PSU: it came with a low quality 550w that got fried 2 days ago so i had to replace it with a decent one. (be quiet straight power 11 750w)
x2 120mm case fans: one Chinese no name, another corsair DC
Samsung 860 pro 500gb SSD ( I added this when i got the PC in 2019)
I went to buy ram at Mwave and the guy told me to forget buying a second 8gb stick to combine with my current one. he said just buy new 16gb ram as combining two different brands will cause issues and might not work. I've googled this and i don't know how true that is, can anyone with more info on this chime in or even recommend a well priced ram (max 16gb) for this MOBO and CPU setup. should i just pick up a second 8gb cheap brand or should I buy a more mid range 16gb new set?
what speed of ram should i get that fits my MOBO and CPU? will buying faster speed ram than what my MOBO and CPU can support make the ram obsolete, would the ram still work at the maximum supported speed of the MOBO and CPU or will it not work at all?
