ATX250W A250 POWER SUPPLY

The ATX250W A250 POWER SUPPLY is an entry-level, budget-friendly PSU designed to power basic desktop computers for office work, home use, schools, and internet browsing. While not intended for gaming rigs or high-power systems, the A250 provides reliable, stable DC power for low-consumption builds with integrated graphics or low-end discrete GPUs. With a continuous output of 250 watts (300W peak), it is ideally suited for systems powered by Intel Celeron, Pentium, or low-end Core i3 processors, as well as AMD Athlon or Ryzen 3 APU-based builds, leaving ample headroom for stable operation.

The A250 includes all necessary cables and connectors for a basic modern PC. Its non-modular design keeps costs low, and the fixed cables are neatly sleeved for basic cable management inside standard cases.

• 20+4 Pin Main Connector: Compatible with both older 20-pin and modern 24-pin motherboards
• 4+4 Pin CPU Connector: Powers CPU on most standard motherboards
• 2-3 SATA Connectors: Supports SSDs, HDDs, and optical drives
• 2 Molex Connectors: For older fans, case lights, or adapter use

The built-in 80mm or 92mm silent fan runs at low RPM during normal operation, drawing cool air through the PSU and exhausting hot air out the rear. Under typical office workloads, the fan remains quiet and unobtrusive — perfect for noise-sensitive environments like libraries or shared offices.

While not a high-end unit, the A250 includes fundamental protection features to safeguard your components against electrical faults or abnormal conditions:

• Over Voltage Protection (OVP): Prevents output voltages from exceeding safe limits
• Over Current Protection (OCP): Limits current on each output rail
• Short Circuit Protection (SCP): Shuts down the PSU in case of a short on any output

Housed in a standard ATX steel chassis measuring 140 x 150 x 86mm, the A250 fits virtually all ATX, Micro-ATX, and Mini-ITX cases. The black powder-coated finish resists rust and scratches, while the standard screw hole pattern ensures easy installation.

Recommended System Configurations (250W Capacity):

• Intel Celeron/Pentium + Integrated Graphics
• AMD Athlon/Ryzen 3 APU (No discrete GPU)
• Office PC with SSD + 1 HDD
• Thin client or POS system / Home theater PC (HTPC)
• School computer lab workstations

Not Recommended For:

• Gaming systems with dedicated graphics cards (GTX/RTX/Radeon)
• High-end Intel Core i7/i9 or AMD Ryzen 7/9 processors
• Multiple hard drives or high-power peripherals
• Overclocking or high-performance workloads

Installation Notes:

• Ensure your total system power draw does not exceed 250W continuous
• For systems drawing close to 250W, consider a higher-wattage PSU for headroom
• Use a surge protector or UPS for additional electrical safety
