SilverStone SX500-G (2017)

Introduced in late August 2017 as part of SilverStone’s SX‑G SFX lineup, the SX500‑G is a 500 W, 80 PLUS Gold, fully modular SFX power supply; its 80 PLUS certification test was dated 2017‑08‑28. It adheres to ATX12V v2.4 (pre‑ATX 3.0) and was reviewed shortly after launch.Sourcetomshardware.com↗

Positioned in the high_end tier for SFX PSUs, it exists to power compact builds that still need mainstream GPU capability without ATX space. It’s well‑suited to SFX/small‑form‑factor and mid-range gaming PCs thanks to its 500 W capacity, Gold efficiency, and fully modular flat cables; it provides two 6+2‑pin PCIe leads but no native 12VHPWR, so newer ATX 3.0 GPUs may require adapters or a higher‑wattage alternative. Notably, this model moved to a 92 mm fan from earlier 80 mm SFX designs to improve acoustics.Sourcesilverstonetek.com↗
