Computer Power Supplies
Computer Power Supplies (PSUs) deliver reliable, stable power to all system components, ensuring safe and efficient performance. A quality power supply protects your hardware from electrical fluctuations, minimizes energy loss, and keeps your build running quietly. Discover a comprehensive range of power supplies at Motivs.lv, designed to match everyday desktop needs as well as high-performance gaming and workstation builds.
The power supply unit is a vital component in any PC, converting AC power from the wall into clean DC power required by the motherboard, processor, graphics card, and storage devices. Choosing a high-grade PSU ensures system stability, component longevity, and optimal thermal management.
Key Factors to Consider When Choosing a PSU
To find the right power supply for your build, consider the following technical specifications:
- Wattage (W): Calculate the total power requirement of your CPU, GPU, and peripherals, adding a 20–30% overhead for system stability and potential future upgrades.
- 80 PLUS Certification: Ratings such as Bronze, Silver, Gold, Platinum, and Titanium verify high electrical efficiency, resulting in less heat generation and lower power consumption.
- Modularity: Non-modular units have fixed cables, while semi-modular and fully modular units allow you to connect only the required cables, improving case airflow and aesthetics.
- Form Factor: ATX is the standard size for most desktop cases, while SFX and TFX units are designed for compact, small-form-factor builds.
- Protection Circuits: Essential safeguards such as OVP, OPP, SCP, UVP, and OTP protect your hardware against voltage spikes, short circuits, and overheating.

Frequently Asked Questions
What wattage PSU do I need for my computer?
Basic office systems generally require 400W to 500W, whereas modern gaming PCs and workstations with dedicated graphics cards typically need 650W to 850W or more.
What does an 80 PLUS certification mean?
The 80 PLUS certification guarantees that the power supply converts at least 80% of AC power into DC power at various loads, reducing wasted energy and heat.
What is the difference between modular and non-modular PSUs?
Non-modular PSUs have all cables permanently attached, while modular PSUs let you plug in only the necessary cables, simplifying cable management and improving airflow.
