Need advice on $1,500 Gaming & Editing PC Build (AM5 / RTX 4070)

Help Fine-Tuning My PC Build

Hey everyone! I’m planning my next PC build and would love some feedback from the community before ordering parts.

Budget: ~$1,500 USD
Primary Use: 1440p High-Refresh Gaming & Light Video Editing
Country: US (near a Micro Center)

Planned Component List

• CPU: AMD Ryzen 7 7800X3D
• Cooler: Thermalright Peerless Assassin 120 SE
• Motherboard: MSI B650 GAMING PLUS WIFI
• RAM: G.Skill Flare X5 32 GB (2 x 16 GB) DDR5-6000 CL30
• Storage: Crucial T500 2TB PCIe Gen4 NVMe SSD
• GPU: NVIDIA GeForce RTX 4070 Super 12GB
• Case: Corsair 4000D Airflow
• Power Supply: Corsair RM750e (2023) 750 W 80+ Gold

Specific Questions I Have:

1. Is the 750W PSU sufficient for this setup, or should I headroom up to 850W?
2. Are there any physical clearance issues between the RAM and cooler?
3. Would you swap any parts for better value-for-money alternatives?

Thanks in advance for any suggestions!
