I'm planning a PC upgrade focused on the graphics card and airflow. My current system has a Ryzen 7 7700, Radeon RX 6500 XT 4GB, MSI PRO B650-S WIFI motherboard, 32GB of DDR5 memory, an SPCC M.2 PCIe SSD, and an EVGA 650W power supply. I'm not sure which case model I have, but it currently only has one rear exhaust fan. I'm considering a Radeon RX 9070 or something in a similar price range, with a GPU budget of about $1,000 CAD and plans to buy around Black Friday. Would an RX 9070 pair well with the Ryzen 7 7700, and is the 650W PSU sufficient or should I replace it? I'd also like recommendations for the number and placement of case fans, plus anything else I should check before buying. I'm especially unsure about confirming GPU clearance, power-connector requirements, and how to share a photo of the build.

For a typical airflow-focused setup, install three 120mm fans at the front as intake and keep one 120mm fan at the rear as exhaust. If the case supports it, adding a top-rear exhaust can help remove heat, but it usually isn’t necessary with good front intake. Top-front intake fans are generally less useful, and bottom fans are only worth considering if the case and GPU specifically benefit from them. Two front intakes plus the existing rear exhaust is already a solid improvement.
An RX 9070 would be a substantial upgrade from the RX 6500 XT and should pair well with the Ryzen 7 7700, especially for 1440p gaming. Around your budget, it’s likely one of the strongest options to watch for during sales. Check the specific card’s length, thickness, and power connectors against your case and PSU before ordering.
I’d be cautious about keeping the 650W unit. Some RX 9070 models recommend a 750W supply, and the exact EVGA model and age matter a lot. It may run, but a good-quality 750W or 850W PSU would give you more headroom and avoid stressing an older unit. Make sure it has the required PCIe power cables and don’t use questionable adapters.
I’m using air cooling and currently only have the single rear exhaust, so I’m planning to add two front intake fans first.
