Silverstone Technology SX1000 Platinum 1000W SFX-L power supply

SFX-L 1000W Platinum unit

This fully modular SFX-L power supply delivers 1000W of continuous power for small form factor computers. It meets the 80 Plus Platinum efficiency standard and is rated for 24/7 operation at 50? ambient temperature. A single +12V rail provides up to 83.3A for demanding components. The 120mm dual ball bearing fan supports semi-fanless operation for quiet running.

Suitable for compact high-power builds

Builders assembling small form factor systems that need full 1000W capacity will fit this SFX-L unit where standard ATX supplies cannot go. The Platinum rating helps reduce heat and electricity cost under heavy load. Buyers whose cases only accept the shorter SFX form factor cannot use this longer SFX-L design. Systems requiring multiple EPS connectors beyond the modular cables included should verify compatibility first.

Sustained 1000W at 50?

The unit is specified to deliver its full 1000W rating continuously at 50? operating temperature, not just in short bursts. The single +12V rail maintains stable 83.3A output during prolonged heavy workloads. All Japanese capacitors contribute to long-term reliability under sustained thermal stress. Semi-fanless operation keeps noise low until internal temperatures demand active cooling.
