1200 W Platinum power supply
The Silverstone Strider Platinum SST-ST1200-PT delivers 1200 W of continuous power for high-end desktop systems. It meets 80 PLUS Platinum efficiency with a single +12 V rail rated at 100 A. The unit accepts 105 to 264 V input at 47 to 63 Hz. A 139 mm Air Penetrator fan handles cooling.
Thermals, noise and power draw
The 139 mm fan runs semi-fanless at low load and stays within a 40 degree C operating temperature. Efficiency ranges from 89 to 92 percent across typical loads. Active PFC and over-voltage protection keep output stable. MTBF exceeds 100000 hours.
Build fit and modularity
Fully modular cables include 24, 20, 16, 12, 8 and 6 pin connectors for motherboard, CPU, PCIe and SATA devices. An FF141 magnetized fan filter is supplied. The chassis measures 180 mm deep. Strict voltage regulation stays within +/- 3 percent.

Soalan tentang produk ini
How do I install the Silverstone SST-ST1200-PT and which step is commonly missed?
Mount the 180 mm long unit with four screws, connect the 24-pin motherboard cable, both 8-pin EPS cables, required PCIe 6+2-pin cables, and SATA cables; the step often missed is plugging in both 8-pin EPS connectors for CPU power.
What maintenance or replacement will the Silverstone SST-ST1200-PT need later?
The 139 mm fan is the only moving part; clean dust from the included magnetised filter periodically, and if bearing noise appears after many years the fan can be replaced with a standard 139 mm unit.
What limit appears first on the Silverstone SST-ST1200-PT under sustained full load?
The single +12 V rail is rated at 100 A; once the combined GPU and CPU draw reaches that 100 A ceiling the over-current protection will trip, capping continuous output at 1200 W.
