EVGA 220-GT-0550-Y1 Supernova 550 GT 80+ Gold PSU

The EVGA Supernova 550 GT is a fully modular ATX power supply built for mid-range PC systems that value clean cable management and efficient power delivery. Its 80 Plus Gold certification ensures the unit converts power at 87–90% efficiency under typical desktop loads, which translates directly to less heat dumped into your case and marginally lower electricity bills over the life of the supply. The fully modular design means every cable — including the 24-pin ATX and EPS connectors — detaches from the unit, so you route only what your build requires and eliminate unused cable clutter entirely.

At just 150 mm long, the Supernova 550 GT is noticeably shorter than many competing units, giving it an advantage in compact mid-tower and smaller cases where PSU clearance is tight. The Fluid Dynamic Bearing fan keeps acoustic output low during normal operation, making it a solid choice for workstations or living room PCs where noise matters. With 550 watts of continuous power, it comfortably drives builds pairing a modern mid-range CPU with GPUs up to roughly the RTX 4060 class, though users planning for higher-draw components should look at the larger wattage models in the Supernova GT lineup. EVGA's 7-year warranty rounds out the package with long-term peace of mind.
