Power for mainstream builds

The Silverstone SST-ET750-HG is a 750 W ATX12V unit built for standard desktop systems. Its semi-modular design keeps cable clutter low while the 80 PLUS Gold rating confirms 87% to 90% efficiency across typical loads. A single 140 mm fan runs at 18 dBA for quiet home or office use. Continuous output is rated at 40 °C ambient temperature.

Single +12 V rail at 62 A

All 750 W are delivered on one +12 V rail rated at 62 A, so high-end graphics cards draw clean power without multi-rail balancing. Four 6+2-pin PCIe connectors support dual GPU setups, while two EPS 8-pin cables feed modern motherboards. Nine SATA and three peripheral plugs cover storage and accessories.

Suits quiet mid-range rigs

Builders who want Gold efficiency, semi-modular cabling and a 160 mm depth will fit this unit in most cases. Systems needing fully modular cables, higher wattage or tighter length limits should consider other models.

Questions about this item

How much power does the 750 W rating actually deliver to the components in my build?

The unit provides a continuous 750 W total output with a single +12 V rail rated at 62 A, while the +3.3 V and +5 V rails are each rated at 22 A.

What does the 80 PLUS Gold certification mean for everyday efficiency and heat?

Efficiency stays between 87 % and 90 % from 20 % to 100 % load, so less energy is wasted as heat and the 140 mm fan can run at lower speed.

Will the 160 mm length and semi-modular cables fit my mid-tower case and leave room for routing?

At 160 mm long it fits most standard ATX cases, and the semi-modular design lets you attach only the PCIe, SATA and peripheral cables you need.
