Upgrading the power supply unit (PSU) in your FormD T1 case can enhance system performance and accommodate more demanding components. Here’s what you need to know:

PSU Compatibility:

• SFX and SFX-L PSUs: The FormD T1 supports both SFX and SFX-L power supplies. However, using an SFX-L PSU with an all-in-one (AIO) liquid cooler can be challenging due to limited space for cable and tube management. It’s feasible but may require meticulous planning.

Custom Cable Kits:

• Optimized Cable Management: Given the compact nature of the T1, custom cable kits can significantly improve airflow and aesthetics. Vendors like Clack Attack offer custom-length power supply cables tailored for the FormD T1, available in various configurations to suit different PSU orientations.

Recommended SFX PSUs:

• Corsair SF1000L: This fully modular 1000W SFX power supply is known for its compact size and high efficiency, making it a suitable choice for high-performance builds.
• Lian Li SP850: This 850W SFX PSU is praised for its performance and compact design, fitting well within small form factor cases like the FormD T1.

Installation Considerations:

• Space Constraints: The T1’s compact design means that installing larger PSUs, especially SFX-L models, can limit space for other components and complicate cable management. Opting for an SFX PSU can alleviate some of these challenges.
• Cooling Solutions: If planning to use an AIO cooler, be mindful of the space occupied by the PSU and the cooler’s radiator and tubing. Proper planning is essential to ensure all components fit without obstructing airflow.
