The Corsair SF850 (2024) is widely regarded by the Reddit community as a top-tier SFX power supply, frequently cited for its 80+ Platinum efficiency and A+ ranking on enthusiast tier lists. While it is praised for its compact size and cool operation, users frequently highlight that the cables are exceptionally stiff, which can make cable management challenging in small form factor builds.

The parts look good imo , one of the best SFX psu A+ Tier in the psu tierlist.
850W for higher midrange GPUs sounds perfect just about now.
I'd go with the Asrock board. They're a sister company of ASUS, though they run independently. Asrock are generally some of the best bang for the buck motherboards on the market. They've been a pariah within AMD builds lately due to some issues with high CPU failure rates on Ryzen X3D CPUs, but before that they were generally my go to suggestion for people and they're still excellent options for Intel.
