Understanding SMPS for Computers: Types, Features, and Specifications

Switch Mode Power Supply (SMPS) is an essential component of any computer system, providing the necessary power to all hardware components. At Bison Infosolutions, we offer a variety of SMPS units tailored to meet different computing needs. This article will delve into the types, technology, specifications, and features of SMPS units to help you make an informed decision.

What is an SMPS?

An SMPS is a power supply unit that converts electrical power efficiently using switching regulators. It is designed to provide stable and reliable power to a computer's components while minimizing energy losses.

Types of SMPS

1. ATX Power Supply

   • Inception Year: Introduced in 1995.
   • Sizes: Standard size is 150mm x 140mm x 86mm (5.9" x 5.5" x 3.4").
   • Technology Used: Utilizes a switching regulator for efficiency.
   • Fan Sizes: Typically 80mm to 120mm fans for cooling.
   • Thickness: Generally around 86mm.
   • Standard Features: Offers a range of wattages, usually between 300W to 1200W, with connectors for all major components (motherboard, GPU, drives).

2. SFX Power Supply

   • Inception Year: Gained traction in the early 2000s.
   • Sizes: Smaller than ATX, approximately 125mm x 100mm x 63.5mm (4.9" x 3.9" x 2.5").
   • Technology Used: Similar to ATX but optimized for compact systems.
   • Fan Sizes: Typically uses 80mm fans.
   • Thickness: Approximately 63.5mm.
   • Standard Features: Designed for small form factor (SFF) cases, offering lower wattages (300W to 600W).

3. TFX Power Supply

   • Inception Year: Introduced in the early 2000s.
   • Sizes: Dimensions are around 150mm x 85mm x 65mm (5.9" x 3.3" x 2.6").
   • Technology Used: Switching technology for improved efficiency.
   • Fan Sizes: Generally 80mm.
   • Thickness: Roughly 65mm.
   • Standard Features: Commonly found in OEM systems, offering moderate power (300W to 600W).

4. Flex ATX Power Supply

   • Inception Year: Introduced in the late 1990s.
   • Sizes: Small and compact, approximately 150mm x 81mm x 40mm (5.9" x 3.2" x 1.6").
   • Technology Used: Switching technology for compact builds.
   • Fan Sizes: Generally 40mm to 60mm fans.
   • Thickness: Approximately 40mm.
   • Standard Features: Ideal for slim and compact systems, typically offers lower wattages (300W to 450W).

Key Specifications

• Wattage Ratings: Vary widely, typically ranging from 300W to 1200W, depending on the model.
• Connectors: Includes 24-pin ATX power connector, 4/8-pin CPU connectors, SATA power connectors, and PCIe connectors for graphics cards.
• Efficiency Ratings: Look for units with 80 PLUS certification (Bronze, Silver, Gold, Platinum) for energy efficiency.
• Cooling Systems: Effective cooling mechanisms, including active and passive cooling options.
