I'm in the process of building my PC and I've already got some solid components: a 9070 XT graphics card, a Ryzen 7 9800 processor, 32 GB of DDR5 RAM, and an SSD. Now I'm looking for advice on a few remaining parts: the power supply unit (PSU), cooling system, and case. I've been thinking about getting an 850W PSU, but is that a good choice for my setup? For the cooling, would a liquid cooler be worthwhile, and if so, what's a budget-friendly option? Lastly, I'm feeling a bit confused about case selection—should I go for one with pre-installed fans, and how large does it need to be for my build?

An 850W PSU is definitely enough for your build, especially if you pick a reliable brand like Corsair or Seasonic with at least an 80+ Gold rating for efficiency. For cooling, you don't necessarily need liquid; a solid dual tower air cooler would perform well too. Regarding the case, just ensure it’s big enough for your motherboard and consider getting one with fans to keep airflow optimal.
For a cooling solution, I'd recommend going for a budget-friendly 360mm AIO liquid cooler from Thermalright. They have good models around $50, just make sure your case can accommodate it. An 850W PSU should work just fine for your setup!

So if I get a case with fans included, I might only need to worry about the CPU cooler, right? So dual tower air coolers are a good option?
