A GTX 1650 Super can be used without a PSU upgrade, but it risks maxing out the 280W PSU if you prefer minimal upgrades.

For future-proofing, consider a Ryzen 5 2600 with an ASRock B450M motherboard and G.Skill Aegis 16GB DDR4-3200 RAM for significant performance improvement.

Owners successfully upgraded the H520 with two 8GB Crucial DDR3L RAM modules, confirming compatibility for a total of 16GB RAM despite Lenovo's specifications.

A low profile GTX 1050 GPU has been reported to work well with the Lenovo H520, offering a feasible graphics upgrade option.

The current setup can handle high settings at 1080p for games like Apex Legends and GTA V at 60fps, but may need adjustments for 1% lows.

For 1080p 60fps gaming, lowering textures to medium or low may be necessary due to the 8GB RAM limitation.

The existing motherboard will not support newer CPUs, necessitating an entire platform upgrade if more processing power is needed.

Compatibility with Windows 11 Pro was achieved using the upgraded RAM, indicating potential for running modern operating systems on this older hardware.

Users recommend buying components at the last possible moment to benefit from potential price drops and compatibility improvements.

The H520 supports a standard 24-pin motherboard power connector, allowing for easier PSU upgrades with TFX form factor units.
