If you are building or upgrading a PC, choosing the right power supply unit (PSU) is one of the most crucial decisions you will make. Many people think that any PSU will work as long as it fits into the case, but this is not true. A wrong power supply can lead to performance issues, system crashes, or even hardware damage.
At Lansotech Solutions, we specialize in providing high-quality power supplies in Kenya, ensuring your PC runs efficiently and safely. In this guide, we will help you understand how to choose the best PSU for your PC and why buying just any power supply can be a big mistake.
1. Why Is a Power Supply Important for Your PC?
A power supply unit (PSU) is responsible for converting electricity from your wall socket into usable power for your computer’s components. It ensures that the motherboard, CPU, GPU, RAM, and other parts receive the right amount of power without fluctuations.
If your PSU is low-quality or incompatible, you may experience:
✅ System instability and random shutdowns
✅ Reduced performance in gaming and professional tasks
✅ Shortened lifespan of components due to power fluctuations
✅ Risk of damaging expensive components like the motherboard and graphics card
2. Can You Buy Any Power Supply for Your PC?
No, you cannot buy just any PSU for your PC. Different power supplies have different wattages, efficiency ratings, connectors, and build qualities. You need to choose one that matches your system’s power requirements and quality standards.
3. Factors to Consider When Buying a Power Supply in Kenya
Before purchasing a PSU, consider the following key factors:
3.1. Wattage – How Much Power Do You Need?
Every PC has specific power needs based on its components. A gaming PC with a high-end graphics card requires more power than a basic office computer.
Here’s a rough estimate of power requirements:
- Basic office PC (No GPU): 300W – 400W
- Mid-range gaming PC: 500W – 700W
- High-end gaming or workstation PC: 750W – 1000W
- Extreme gaming & content creation PCs: 1000W+
👉 How to Calculate Your Power Needs: Use an online PSU wattage calculator or check the power requirements of your GPU and CPU.
3.2. PSU Efficiency Rating (80 PLUS Certification)
Power supplies have efficiency ratings that determine how much energy is converted into usable power. The higher the efficiency, the less energy is wasted as heat.
Common 80 PLUS certification ratings:
✔️ 80 PLUS White: Basic efficiency (~80%)
✔️ 80 PLUS Bronze: Good for budget PCs (~82–85%)
✔️ 80 PLUS Silver/Gold: Recommended for gaming PCs (~87–92%)
✔️ 80 PLUS Platinum/Titanium: Best for high-end setups (~92–96%)
For gaming PCs and professional workstations, we recommend 80 PLUS Gold or higher for efficiency and stability.
3.3. Modular vs. Non-Modular PSU
- Non-modular PSUs: Fixed cables; harder to manage.
- Semi-modular PSUs: Some detachable cables for better airflow.
- Fully modular PSUs: All cables are detachable for the best cable management.
For cleaner setups and better airflow, we recommend semi-modular or fully modular PSUs.
3.4. Compatibility – Will It Fit in Your PC Case?
PSUs come in different sizes:
- ATX: Standard size for most desktops.
- SFX: Smaller PSUs for compact PC cases.
- TFX/Flex ATX: For ultra-small form factor (SFF) PCs.
Make sure to check your case size before purchasing a power supply.
3.5. Power Supply Connectors
Ensure the PSU has the right connectors for your components:
🔌 24-pin connector – For the motherboard (6-pin, 8-pin, or 12-pin)
🔌 4-pin CPU connector – For the processor
🔌 8-pin CPU connector – For the processor
🔌 PCIe connectors – For the graphics card (6-pin, 8-pin, or 12-pin)
🔌 SATA & Molex connectors – For storage drives and peripherals
Buying a future-proof PSU with multiple connectors ensures compatibility with upgrades.
3.6. Brand and Build Quality – Why Cheap PSUs Are Dangerous
Cheap, generic power supplies lack safety features and often fail under load, causing system crashes or even fires.
At Lansotech Solutions, we recommend trusted brands such as:
✔️ Corsair
✔️ EVGA
✔️ Seasonic
✔️ Cooler Master
✔️ Thermaltake
✔️ ASUS ROG
✔️ HP
✔️ DELL
✔️ LENOVO
✔️ DELTA
✔️ AC Bell
✔️ FSP Group
✔️ Acer
✔️ ASUS
✔️ MSI
✔️ Seasonic
These brands offer high-quality components, stable power delivery, and safety protections like over-voltage and short-circuit protection.

5. FAQs – Power Supply Buying Guide
Q1: What happens if I buy an underpowered PSU?
If your PSU doesn’t provide enough power, your PC may randomly shut down, crash, or fail to boot.
Q2: Can I use a 1000W PSU on a PC that only needs 500W?
Yes! A higher-wattage PSU won’t damage your PC. It will only supply the amount of power needed.
Q3: Should I replace my PSU when upgrading my GPU?
If your new GPU requires more power, you may need a higher-wattage PSU with the right PCIe connectors.
Q4: How long does a PSU last?
A high-quality PSU can last 5–10 years. Cheap power supplies, however, may fail within a year.
Q5: What is the best PSU for gaming in Kenya?
We recommend Corsair RM750x, EVGA SuperNOVA 850W, or Seasonic Focus GX-750 for gaming PCs.
