Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

The Power Supply Unit Chieftec CTG-650C 650 W is a 650-watt ATX power supply designed for desktop PC systems. It provides a 24-pin ATX motherboard connector, semi-modular cable management, and active cooling via a 120 mm fan. The unit is rated with 80 PLUS efficiency and is built to meet common safety and environmental standards, making it suitable for mainstream builds where a balance of power, efficiency and affordability is required.

Advantages

The Chieftec CTG-650C offers reliable continuous output up to 650 W with an overall efficiency around 85%, reducing wasted energy and heat compared with lower-efficiency models. Semi-modular cabling simplifies installation and improves internal airflow by allowing unused cables to be removed. A 120 mm fan provides active cooling with low acoustic signature under normal loads. The matte black housing supports a discreet installation in a variety of case designs.

Suitable for

  • Mainstream desktop PCs for office, home or light gaming use

When it may not be suitable

This PSU may not be suitable for high-end gaming rigs or workstation systems that require peak power beyond 650 W or demand fully modular cabling and multiple high-current PCIe rails for multi-GPU configurations. Users planning extreme overclocking or very power-hungry components should select a higher-rated or more specialized power supply.

Key specifications

  • Total power output: 650 W
  • Efficiency: approximately 85% (80 PLUS certified)
  • Motherboard connector: 24-pin ATX
  • Cabling: semi-modular design
  • Cooling: 120 mm fan (active)
  • Input: AC 230 V, 50 Hz
  • Colour: Black

How to use

Install the PSU in a compatible ATX case following manufacturer guidelines: position the unit to align screw holes, secure it with mounting screws, and connect the 24-pin ATX cable to the motherboard. Attach required peripheral connectors and CPU/PCIe cables from the semi-modular harness as needed. Ensure the AC mains rating matches local supply and connect the power cable. Verify BIOS/UEFI and system stability after first power-up and monitor temperatures and voltages during initial use.

What to consider before purchase

  • Required total system power and headroom for future upgrades
  • Compatibility of available connectors with your motherboard, CPU and GPU
  • Case size and mounting orientation to ensure airflow and fan clearance
  • Importance of semi-modular cabling versus fully modular designs

Recommendations

For typical home, office and light gaming systems, allow 20–30% headroom above estimated continuous system consumption to ensure stable operation and longevity. Keep intake and exhaust airflow unobstructed and perform periodic dust cleaning of the 120 mm fan and PSU vents to maintain cooling efficiency.

Verdict: Chieftec's A-80 power supply does exactly what it says on the tin: great performance without a significant price tag. Even though we are not 100% sure of the OEM used I can still say with confidence that the Chieftec A-80 650W is a quality power supply. I...

Pros
  • Excellent voltage regulation
  • Quiet operation under most loads
  • Good ripple suppression
  • High PFC
  • Low price
  • Betters its 80 Plus Bronze certification
Cons
  • Not the nicest exterior (of the cables or unit)
  • Could do with more PCIe
  • 2 year warranty is a little short
