SilverStone today expanded the Strider Gold S line of PSUs almost five years since the series made its debut with 750W and 850W models. The company today got around to launching new 550W and 650W models. Both 80 Plus Gold-certified PSUs feature fully modular cabling, and a body length of just 140 mm. Some of their innards have modernized since their older siblings, including ATX v2.4 support, and support for the latest processor lower C-states. For both these models, only the +12V is counted toward their nameplate Wattage, and both come with 100W +3.3V and +5V.

The 550W model comes with two 6+2 pin PCIe power connectors, while the 650W model comes with four. The 650W comes with a few more Molex connectors than the 550W model. Both offer single 4+4 pin EPS, and eight SATA power, besides the obligatory 24-pin ATX. The units are cooled by 120 mm fans. Under the hood, you get single +12V rail design, active PFC, and most common electrical protections, against over/under-voltage, overload, overheat, and short-circuit. The company didn't specify pricing.
