Compact SFX power supply for small-form-factor
The Seasonic SSP-300SFG is a 300 W SFX12V unit designed for compact cases where space is at a premium. Its 140 mm length and single-fan layout leave room for unrestricted airflow. The supply is Haswell ready and carries 80 PLUS Gold certification for high efficiency. Japanese capacitors and a DC-to-DC converter design support stable output across varying loads.
300 W capacity with a single +12 V rail at 25 A
The +12 V rail delivers up to 25 A, covering the needs of mainstream CPUs and mid-range graphics cards in tight enclosures. Minor rails provide 3.3 V at 10 A and 5 V at 14 A for legacy drives and peripherals. Peak combined output reaches 300 W, so sustained heavy loads on both CPU and GPU may exceed the unit's headroom. Three SATA connectors and a 4+4-pin CPU plug handle typical storage and processor power.
80 PLUS Gold efficiency at 87 % typical
The 80 PLUS Gold rating means the supply runs at 87 % typical efficiency, reducing waste heat and electricity cost. Active PFC corrects the power factor across a 100 to 240 V input range. Protections include over-voltage, short-circuit and over-power safeguards on all outputs. A super-low-noise fan control keeps acoustic output minimal during light workloads.

商品問答
Will this SFX power supply fit in a case that accepts 140 mm long units?
The unit is 140 mm long, so it fits cases that accept SFX power supplies up to that length.
Can the single 12 V rail deliver enough current for a modern CPU and graphics card?
The 12 V rail is rated at 25 A, providing 300 W total; check your components' combined 12 V draw against that limit.
Does the 24-pin main connector and 4+4-pin CPU connector cover a standard ATX motherboard?
Yes, the PSU includes a 24-pin main connector and a 4+4-pin ATX12V connector for standard motherboards.
