Power Supply Unit Silverstone ST1100-TI v2.0 1100 W

The Silverstone ST1100-TI v2.0 1100 W is a high-performance desktop power supply unit engineered for reliable DC power delivery in gaming rigs, workstations and compact systems. It provides a continuous 1100 W output with peak capability up to 1200 W and operates across an AC input range of 90–264 V. The unit implements 80 PLUS Titanium efficiency to reduce energy loss and heat generation, and includes a 20+4 pin ATX motherboard connector plus a set of SATA power cables. Its compact chassis dimensions and a single 135 mm fan support effective cooling while keeping overall footprint suitable for many PC cases.

Advantages

The PSU delivers high conversion efficiency (approximately 94%) thanks to 80 PLUS Titanium certification, which improves energy savings and lowers operating temperatures during sustained loads. The broad AC input range and stable power delivery help protect connected components under varying mains conditions. Compact physical dimensions and a dedicated 55 cm motherboard cable plus SATA cables (150 mm and 600 mm) simplify cable routing. A single 135 mm fan balances cooling performance and acoustic level.

Suitable for

• High-performance gaming PCs with multi-GPU or high-core-count CPUs
• Professional workstations used for CAD, video editing or 3D rendering
• Compact ATX or mid-tower systems requiring a shorter-depth PSU
• Systems where high efficiency and reduced heat output are desired

How to use

Install the Silverstone ST1100-TI v2.0 into a compatible ATX power supply bay following standard PC assembly procedures. Secure the PSU with screws, connect the 20+4 pin ATX connector to the motherboard, and attach SATA power cables to storage devices as required. Ensure the AC mains input matches the PSU input range and use a properly rated mains cable and surge protection. Route cables to maintain unobstructed airflow to the 135 mm fan and verify all connections before powering on the system.

Recommendations

For sustained heavy loads, allow adequate case airflow to support the PSU fan and maintain optimal efficiency. Regularly inspect cables and connectors for firm seating, and consider using a quality surge protector or UPS when operating in areas with unstable mains voltage.
