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.

Questions about this item

How often will the 135 mm fan need cleaning or replacement?

The unit uses a single 135 mm fan rated for continuous operation at 50 °C; with an MTBF above 100,000 hours the fan should last many years, and only occasional dust removal is required.

What limits sustained output before the protection circuits engage?

The single +12 V rail delivers up to 125 A; overload protection activates if that current or the 1500 W total is exceeded.

How loud and hot does the 135 mm fan get during all-day 1500 W loads?

The semi-fanless design keeps the fan off at low load; under full load it runs at 50 °C ambient while maintaining 90 to 94 percent efficiency, so waste heat and noise stay low.
