Power supply Makki PSU 550W PFC Version 2

Makki PSU 550W PFC Version 2 is a standard ATX power supply with 550W power, aimed at budget and simpler gaming or office configurations. It operates in a wide range of 100 – 240 VAC, making it suitable for any home or office conditions. It comes with a 120mm fan for cooling and a basic 80% efficiency, without an official certification. The format is ATX with compact dimensions, so it fits without drama in most standard cases.

What you get

With a real 550W and two PCI-Express 6+2 pin connectors, you can safely power a basic to mid-range GPU without needing adapters. The 4+4 Pin ATX/EPS connector covers standard desktop CPU platforms, and with 20+4 Pin ATX, you can power modern and older motherboards without issues. You have 3 x SATA and 3 x Molex connectors – enough for a combination of SSD, HDD, and additional fans or accessories. The 600mm cable length gives a bit more freedom for cable management in larger cases and makes it easier to route behind the panel.

• Power 550W – suitable for budget and mid-range configurations with one GPU and several storage devices.
• Efficiency around 80% – basic level, which is fine for everyday use, although without an official 80 Plus certification.
• Passive PFC – a simpler PFC scheme, sufficient for standard systems without extreme loads.
• 2 x PCI-Express 6+2 pin – allows powering a graphics card with up to two additional power connectors without the need for adapters.
• 3 x SATA and 3 x Molex – flexibility for a combination of SSD, HDD, optical drives, and peripherals with Molex power.
• 120mm fan – standard cooling that maintains acceptable temperatures under normal load.
• 600mm cables and ATX format – convenient for installation in most mid-tower and full-tower cases with the possibility of hidden cabling.

Who it is suitable for

This power supply is a good option if you are building a budget or entry-level gaming build, office machine, or home computer without plans for a high-end GPU and heavy overclocking. If you are aiming for maximum efficiency, quiet operation under high load, or a multi-component high-end system, it would be better to look for a higher-class PSU with a more serious certification.

The most sensible aspect here is the combination of 550W power, 2 PCIe connectors, and long 600mm cables, making it a practical choice for clean, budget configurations without unnecessary extras.
