Best PSU for RX 7600? And should I replace my case too?
I’m planning to upgrade my PC soon and wanted some advice before buying parts.
Current specs:
Ryzen 5 5600G
Gigabyte A520M S2H
16GB (2x8GB) DDR4
currently using Vega 7 integrated graphics
I live in Brazil and my budget for the upgrade is around R$2000–3000 total (roughly USD $350–550 over time).
My main plan is getting an RX 7600 (around R$1400–1600 / USD $250–290 here), but I’m still deciding a few things.
First: what would be the best PSU choice in terms of:
safety/reliability
good components
value for the money
enough headroom without overspending
I’m also unsure how many watts I actually need for this setup.
Would a good 550W PSU already be enough, or is it smarter to go for 650W?
My current PSU is very old and sketchy:
“Total Output Maximum”: 450W
“Real Output”: 200W
so I definitely plan to replace it before getting a GPU.
I’ve seen recommendations for:
MSI MAG A650BN
Corsair CX650
Cooler Master MWE
XPG Pylon
but I’m not sure which ones are currently the best/least risky options.
Also: is the RX 7600 still the best value upgrade for this kind of setup, or is there a better option around the same price range?
Another thing: my current case is an old office-style case with very limited airflow (basically only a side opening). Would it be fine to keep it with a dual-fan RX 7600, or should I replace the case too?
I’m trying to balance:
good thermals
low risk
and overall cost-benefit
Any advice or recommendations would help a lot.
