Coconut SM65 X550 550W 80 Plus Bronze Non-Modular Power Supply

The Coconut SM65 X550 is a 550-watt ATX power supply designed for everyday desktop builds that demand dependable power delivery without unnecessary complexity. Carrying the 80 Plus Bronze certification, it is verified to deliver above 85% efficiency at typical load levels, which translates to lower heat output and reduced electricity consumption compared to uncertified units. The non-modular flat cable design keeps the wiring tidy and offers a softer, more manageable grip during installation — a practical choice for builders who prioritise straightforward assembly. Cooling is handled by a hydraulic-bearing (HDB) fan, a bearing type known for producing less noise and lasting longer than sleeve-bearing alternatives. The unit is rated for continuous operation at up to 40°C ambient temperature, making it suitable for systems housed in moderately warm enclosures or placed in environments without aggressive air conditioning. The SM65 X550 supports ATX form-factor motherboards and is compliant with ATX standards, including the capacity to handle transient peak loads up to 1.5 times the rated wattage — as tested at 25°C ambient conditions. All performance figures stated by the manufacturer are confirmed under 25°C ambient temperature testing; real-world results may vary depending on system load and environment. Connectivity covers common build requirements for a mid-range system, with one PCIe 6+2-pin connector for a discrete GPU, four SATA power connectors for storage devices, and two 4-pin peripheral connectors for accessories such as fans or optical drives. The ATX main connector and CPU power connectors are included as standard non-modular leads. The unit ships with a 3-year manufacturer warranty, providing meaningful coverage for a component category where longevity matters.
