500W SFX Gold power supply

The Silverstone SST-SX500-G is a 500 watt SFX form-factor power supply with 80 PLUS Gold certification and full modular cabling. It delivers up to 550 watts maximum power through a single 92 mm fan and active power-factor correction. The unit measures 125 mm in length, making it suitable for compact chassis that accept SFX dimensions. It targets builders who need efficient, cable-managed power in a small footprint.

Suits small-form-factor builds.

This supply suits compact gaming rigs, workstation cubes and HTPC cases that require an SFX unit with Gold efficiency and detachable cables. Builders planning multi-GPU configurations or components that push sustained loads beyond 500 watts should look at higher-capacity ATX or SFX-L units instead. Systems needing redundant or server-grade features are also outside its intended scope.

Straightforward SFX install.

Installation follows the standard SFX mounting pattern with four screws and the included ATX bracket for legacy cases. Full modular cables let you connect only what the build needs, reducing clutter in tight interiors. The main issue reported is routing the 24-pin and EPS cables around sharp bends in very small enclosures, so plan cable paths before finalising the motherboard tray.

Questions about this item

What case clearance do I need for the 125 mm length?

The unit measures 125 mm long, so your case must provide at least that depth in the SFX mounting area.

Will the 92 mm fan fit my existing SFX bracket?

The built-in 92 mm fan sits inside the standard SFX frame, so any bracket that accepts SFX units will accommodate it.

How can I verify the 80 PLUS Gold efficiency is active?

Under typical loads the PSU should run cool and quiet; you can also monitor input versus output power with a watt-meter to confirm the rated efficiency.
