MSI MAG A1250GL PCIE5

Running a 4090 and a 13900K, and this 1250W unit barely breaks a sweat even under full load. The 80 Plus Gold efficiency keeps the room from turning into a space heater during long sessions, and the PCIE5 connector was plug-and-play with my card.

Swapped out a 750W unit for this and the difference in headroom is obvious. It's fully modular, so cable management in my mid-tower actually went quicker than I expected. Zero coil whine so far, which was my main worry with a 1250W unit.

Ran my 13900K and 4090 at full load without a single hiccup, and the fan barely spins even under heavy gaming. The 1250W headroom leaves me plenty of room for future upgrades.
