Description
The SilverStone ST1200-PTS redefines power density by packing 1200W of 80 PLUS Platinum efficiency into a frame just 140mm deep. This compact design achieves a remarkable 664W per liter, making it one of the smallest high-wattage power supplies available. Built for 24/7 continuous operation at 40°C, it features a single +12V rail design and strict ±3% voltage regulation to ensure absolute stability for high-performance components.
This product is for:
- Small Form Factor Enthusiasts: Ideal for builders using compact ATX cases where cable management space is limited but high wattage is required.
- Professional Workstation Users: Designed for 24/7 reliability with all Japanese electrolytic capacitors and a 100,000-hour MTBF.
- Multi-GPU Gamers: Equipped with eight 8/6-pin PCIe connectors to support high-end SLI or Crossfire configurations and modern power-hungry graphics cards.
- Silent PC Builders: Features a 120mm Hybrid Ceramic Bearing (HYB) fan that operates at a minimum of 18 dBA for near-silent performance.
- Overclockers: Provides ultra-low ripple and noise levels with a powerful single +12V rail to maintain system integrity during heavy loads.
Detailed specifications:
- Max DC Output: 1200W (1200W on +12V rail)
- Efficiency: 80 PLUS Platinum (89% ~ 92% at 20% ~ 100% load)
- Form Factor: ATX (150 mm W x 86 mm H x 140 mm D)
- Cooling: 120mm HYB silent fan with FF122 magnetic fan filter included
- Protection: OVP, OCP, OPP, OTP, UVP, SCP
- Connectivity: Fully modular with 1x 24-pin, 2x 4+4-pin EPS, 8x 6+2-pin PCIe, 8x SATA, and 6x Peripheral connectors
Installing the ST1200-PTS is remarkably straightforward thanks to its 140mm depth, which provides extra room for cable routing even in mid-tower cases. The fully modular flat cables further reduce clutter, improving internal airflow. During heavy workloads, the 120mm HYB fan maintains a low acoustic profile, while the included FF122 magnetic dust filter helps keep the internals clean, extending the lifespan of the Japanese capacitors.
While most 1200W power supplies require a chassis depth of 180mm to 200mm, the SilverStone ST1200-PTS achieves the same output in a standard 140mm footprint. This allows it to fit into cases that typically only support lower-wattage units. Unlike standard Gold-rated units, its Platinum certification ensures less heat waste, which is critical in the tighter spaces this unit is designed to inhabit.
Q&A:
- Can this power supply fit in a Micro-ATX case? Yes, its 140mm depth is the standard size for most ATX power supplies, making it highly compatible with smaller cases that support ATX PSUs.
- Does it support the latest NVIDIA and AMD graphics cards? Yes, with eight 6+2-pin PCIe connectors, it provides ample power and connectivity for multiple high-end GPUs.
- What are the benefits of Japanese capacitors? All Japanese electrolytic capacitors offer higher heat resistance and longer lifespans compared to standard components, ensuring 24/7 stability.
- Is the fan loud under load? The unit uses a 120mm HYB fan designed for silence, starting at 18 dBA and maintaining a low noise curve even as power demand increases.
- What safety protections are included? The ST1200-PTS includes a full suite of industrial-grade protections: Over Current, Over Power, Over Voltage, Over Temperature, Under Voltage, and Short Circuit protection.
