Silverstone PS-ST1500-TI 1500W ATX power supply

Built for high-output systems

The Silverstone PS-ST1500-TI delivers 1500 W through a single +12 V rail rated at 125 A. It meets 80 PLUS Titanium efficiency between 90% and 94% from 10% to 100% load. A 135 mm fan runs semi-fanless at low load and the unit is rated for continuous operation at 50 °C. Japanese capacitors and tight voltage regulation support 24/7 reliability.

Fully modular cable set

All cables detach so only the eight 6+2-pin PCIe, sixteen SATA, six peripheral and two EPS connectors needed are installed. Cable lengths include 550 mm for the 24-pin and PCIe leads, 750 mm and 550 mm for the EPS leads, and up to 600 mm for SATA chains. The floppy adapter is also supplied. Removing unused cables improves airflow and simplifies routing in dense builds.

Check clearance and connectors

The power supply is 180 mm long; verify the case allows that depth with cables bent. Confirm the motherboard needs both an 8-pin and a 4-pin EPS socket if dual CPU power is required. Ensure the graphics cards use 6+2-pin PCIe plugs and that the mains supply sits within the 90–264 V, 47–63 Hz input range.
