SFX 450 W power supply

The FSP FSP450-50SAC is a 450 W SFX unit built to the SFX12V 3.3 standard and certified 80 Plus Bronze. It delivers a single +12 V rail and uses an 80 mm fan with intelligent speed control for temperature-based airflow. The 125 mm housing fits SFX, Micro-ATX and Mini-ITX layouts, and an included bracket allows installation in standard ATX cases. Black ribbon cables keep the internal look clean.

Compact builds and ATX retrofits

This supply suits small-form-factor systems that need 450 W from an SFX footprint, and it also works for builders converting an ATX chassis with the bundled bracket. Buyers who need modular cabling to reduce clutter should look elsewhere, as the cables are fixed. Systems that require more than 450 W of continuous power will need a higher-capacity unit.

Straightforward fit with fixed cables

The 125 mm depth slides into most SFX bays, and the ATX bracket screws on without special tools. Because the cables are non-modular, routing the unused leads can be the only awkward step in tight chassis. The wide 100-240 V input handles global mains voltages automatically. Ensure the case allows 125 mm of PSU clearance before ordering.

Questions about this item

Does my case need an SFX slot or the included ATX bracket to mount this 125 mm PSU?

The unit is 125 mm long and ships with an SFX-to-ATX adapter bracket so it fits SFX, Micro-ATX and Mini-ITX cases.

Will the fixed black ribbon cables reach the 24-pin and 8-pin connectors on an older motherboard?

All cables are fixed black ribbon type; measure your board’s connector positions against the cable lengths before buying.

How do I confirm the 80 mm fan is running intelligently after installation?

The fan should spin at low speed when the PSU is cool and ramp up as internal temperature rises.
