Best TFX PSU for Slim Small Form Factor Low Profile PC & HTPC

A TFX PSU is a Thin Form Factor Power Supply for low profile and small form factor computers. Like SFX power supply, TFX power supply is also based on the ATX specifications. TFX power supplies are longer and narrower, which allows them to fit easily in low profile and slim cases. These TFX PSUs comes in lower power capacities, generally up to 300Watts because small form factor systems consumes very less power for their operation.

A TFX Power Supply has typical dimensions as 146×83×64 mm (LxWxH) and they come with top mounted 80mm fan for cooling. The fan can also be used as exhaust fan for taking the out heat generated from processor and motherboard to the surroundings from its back side. Some small form factor and low profile PC cases support only SFX PSUs and some can only take TFX PSU. So, here in this post I am going to list down the best TFX PSUs for your small form factor build.
