Corsair CX550 (550W) 80 Plus Bronze ATX PSU - CP-9020277-EU

This Corsair CX550 is a 550W ATX power supply from budget to mid-range class, aimed at stable gaming and office configurations without unnecessary extras. It relies on 80+ Bronze certification and up to 88% efficiency, which helps your machine run cooler and quieter under normal load. The format is standard ATX, so it fits without drama in most mid-tower cases. There is no RGB and modularity – the idea here is a sturdy, reliable PSU without decoration.

What you get

With a power of 550W and Active PFC, you have a stable power supply for a typical gaming configuration with one GPU and a modern CPU, without worrying about voltage drops. The two 6+2 Pin PCI-E connectors allow you to install a graphics card that requires up to 2 PCIe power connections, while the 24-pin ATX and 4+4-pin CPU cover all standard motherboards and processors in the mainstream class. With 3 x SATA connectors, you can connect an SSD, HDD, and another SATA device (for example, an additional SSD), while 2 x Molex are at hand for fans, pumps, or older hardware. The 120mm F.D.B. fan takes care of cooling, with F.D.B. bearings ensuring quieter operation and longer life compared to cheap sleeve solutions.

• Power 550W – fully sufficient for a mid-range gaming build with a separate GPU and several drives.
• 80+ Bronze certification with efficiency up to 88% – less loss as heat and lower load on the electrical network during long gaming sessions.
• 2 x 6+2 Pin PCI-E connectors – gives you flexibility for graphics cards that require up to two additional power connections.
• 3 x SATA + 2 x Molex – enough connectors for a combination of SSD, HDD, fans, and older peripheral hardware.
• 120mm F.D.B. fan – quieter operation and better durability compared to standard fans with basic bearings.
• Active PFC – more stable power supply and better performance at input voltage from 100 – 240 VAC.
• 60 months warranty – 5 years of peace of mind that the PSU is covered in case of problems.

Who it is suitable for

It is suitable if you are building a budget or mid-range gaming or home/office computer with one graphics card and do not care about modular cables and RGB. If you are thinking about a very heavily overclocked high-end build with a power-hungry GPU, you are already in the territory of higher wattage. But for mainstream configurations up to mid-range level, this model meets the needs without unnecessary complications.

The most sensible thing about this Corsair CX550 is the combination of 550W power, 80+ Bronze efficiency, Active PFC, and quality 120mm F.D.B. fan, backed by a 5-year warranty – a practical choice if you are looking for a reliable power supply without unnecessary effects.
