Power Supply SilverStone Extreme 1000Rz Fully Modular SST-EX1000R-PM 80 Plus Platinum 1000W

SilverStone Extreme 1000Rz 1000W Platinum Fully Modular Power Supply

The Extreme 1000Rz is a compact SFX-format supply that fits a powerful 1000 watts into small chassis. It combines Cybenetics Platinum certification, a fully modular build and broad PCIe 5 support, and is aimed at Small Form Factor systems that demand serious power and high performance.

Power & efficiency

The unit delivers 1000 watts and carries a Cybenetics Platinum efficiency certificate, the high efficiency tier that reduces wasted power and heat output. The supply is designed for continuous 24/7 operation at working temperatures of up to 40℃, which points to lasting stability even under sustained loads.

Cables & connectors

The fully modular build lets you detach every cable and connect only the ones you need, for easy installation in cramped cases. The unit includes four PCIe 5 connectors and a Gen5 12V-2x6 connector that conforms to the Intel SFX12V V4.1 specification for the latest graphics cards. The cable design is flexible with improved insulation for easier routing.

Reliability & cooling

Cooling relies on an especially quiet 92 mm fan with an FDB bearing and a smart shutdown function that silences the fan at low loads. Combined with the compact form factor and the fully modular build, the result is a reliable, tidy power supply for demanding SFF builds.
