Corsair CV550 550W 80+ Bronze Power Supply

The Corsair CV550 is a 550 W power supply for a desktop that does not carry a power-hungry graphics card: an office machine, a study PC, a home build on integrated graphics or a modest card. It is honest capacity at a sensible size, chosen to match the build rather than to leave room for a rig that was never planned. Efficiency is rated at 80 PLUS Bronze, so a reasonable share of what comes from the wall reaches the components instead of turning into heat inside the case. There are two 6+2 pin PCIe connectors for a graphics card, and a 120 mm fan handles cooling. The unit is non-modular, which means every cable is permanently attached at the supply, so plan a little space behind the motherboard tray for the leads a simpler build will not use. Corsair covers it with a three-year warranty. That makes it the right fit for the machines that quietly do most of the work: a shop or chamber PC running all day, a student desktop handling coursework and browsing, an office system where reliability matters far more than headroom. Buying a supply matched to the build, from a maker that stands behind it for three years, is the sensible way to spend here — the power supply is the one part whose failure can take other components with it.
