Power Supply Price in Bangladesh

Modern PCs, especially gaming systems, depend heavily on a high-quality ATX power supply to handle sudden power spikes, GPU boosts, and long gaming sessions. In a desktop PC, the PSU delivers stable power to essential parts like the motherboard, CPU, graphics card (GPU), hard drive (HDD), SSD, and RAM, so choosing the right unit matters for both performance and hardware safety. That’s why selecting the right PSU in Bangladesh should go beyond wattage and price; it should include factors like 12V rail capacity, efficiency certification (80 PLUS / Cybenetics), protection features (OVP, UVP, SCP, OCP), and support for modern platforms like ATX 3.1.

Types of Power Supply

AC Power Supply

An AC power supply delivers alternating current at its output. It is commonly used where devices are designed to operate directly on AC power. AC outputs are not used to power PC components directly.

DC Power Supply

A DC power supply delivers direct current and is widely used in electronics. Computer PSUs ultimately provide DC power rails such as +12V, +5V, and +3.3V, which are required by internal components.

PSU Cable Types

Full Modular PSU

All cables are detachable, improving airflow and cable management. This makes installation and cleaning easier but increases cost. Cables are not interchangeable between different PSU models.

Non-Modular PSU

All cables are permanently attached. These units are more affordable but can create cable clutter, especially in smaller cases.

Semi-Modular PSU

Essential cables are fixed, while others are detachable. This offers a balance between cost and convenience and is suitable for most PC builds.

Key Features of a Power Supply

Wattage

Wattage indicates the maximum power a PSU can deliver. It should comfortably handle peak loads with additional headroom for stability and future upgrades.

MTBF (Mean Time Between Failures)

MTBF is a reliability metric expressed in hours. While not a lifespan guarantee, higher MTBF values generally indicate better build quality.

Efficiency Rating

Efficiency measures how much input power is converted into usable output. Higher efficiency means less heat, lower electricity usage, and quieter operation. Common ratings include 80 PLUS Bronze, Gold, Platinum, and Titanium.

Fan Type and Size

Larger fans and higher-quality bearings reduce noise and increase durability. Some PSUs use semi-passive cooling, keeping the fan off at low loads.

Capacitor Quality

High-quality capacitors ensure stable power delivery and long-term reliability, especially under high temperatures and continuous use.

ATX 3.1 Standard

ATX 3.1 PSUs are designed to handle modern hardware demands, including high transient power spikes from GPUs.

PSU Certifications

Two major certification systems are used to evaluate PSU quality: 80 PLUS and Cybenetics.

Cybenetics Certification

Cybenetics evaluates both efficiency and noise levels under multiple load conditions. Test results are published for transparency, helping users compare real-world performance.

80 PLUS Certification

80 PLUS certification ensures at least 80% efficiency at 20%, 50%, and 100% load. Higher tiers provide better efficiency, reduced heat output, and lower power consumption.

Popular PC Power Supply Brands in Bangladesh

Bangladesh’s PC market offers a wide range of power supply brands covering budget builds, office PCs, gaming systems, and high-performance workstations. Whether you’re looking for a modular PSU, SFF power supply, or a high-wattage ATX 3.1 PSU, the following brands are widely available and trusted by users.

Well-known international and gaming-focused brands include Corsair, ASUS, MSI, GIGABYTE, Cooler Master, Thermaltake, Antec, Super Flower, and Deepcool, which are popular for gaming PCs and high-end builds.

Brands such as Lian Li, NZXT, MONTECH, Xigmatek, and Thermalright focus on clean design, efficient airflow, and premium build quality.

For value-oriented and entry-level systems, users often choose Value-Top, Walton, Max Green, PC Power, Huntkey, Xtreme, and Revenger, which are commonly used in office and home PCs.

Other notable brands available in the Bangladeshi market include FSP, Thermaltake, Gamdias, Redragon, 1STPLAYER, Aigo, Cougar, Monarch, T-WOLF, OCPC, Thunderbolt, and Acer.

These brands offer a wide selection of non-modular, semi-modular, fully modular, and SFF power supplies, making it easier to choose the right PSU in Bangladesh based on performance needs, budget, and system size.

Buying Guide for Power Supplies

Calculate Power Requirements

Estimate total system power usage, focusing on CPU and GPU consumption. Add 20–30% extra capacity for future upgrades and power spikes. Modern GPUs can draw significantly more power during short bursts.

Understand Efficiency Ratings

Bronze-rated PSUs are suitable for basic systems. Gold and higher-rated units are recommended for gaming and high-performance builds due to better efficiency and lower heat output.

Choose the Right Form Factor

ATX is the standard size for most desktop PCs. SFX and SFX-L are compact alternatives for small form factor builds.

Decide on Modularity

Modular and semi-modular PSUs improve airflow and aesthetics by reducing unused cables. Non-modular units are suitable for budget-focused builds.

Check Connectors

Ensure the PSU includes sufficient connectors for your motherboard, CPU, GPU, and storage devices. High-end GPUs may require 12V 2x6 or multiple PCIe connectors.

Protection Features

A quality PSU should include overvoltage, undervoltage, overcurrent, short-circuit, over-power, and over-temperature protection.

Reliability and Warranty

Choose a PSU with at least a 03 year warranty and an MTBF above 100,000 hours. Reliable cooling and recognized certifications are important indicators of quality.
