The Corsair CX750 is a 750-watt, non-modular ATX power supply selling for £57.99, and it sits sixth in this guide. The bullet text promises 80 PLUS Bronze certification with up to 88% operational efficiency, guaranteed full continuous power, a 120mm thermally controlled low-noise fan, and a 125mm casing that it says fits almost all modern PC cases. Its Amazon rating is 4.5 out of 5 from 438 ratings, and 78 of those are five-star.

The row worth checking here is the input voltage. The spec table lists "Maximum Input Voltage: 230 Volts" and "Minimum Input Voltage: 230 Volts (AC)" — the same figure at both ends, so no tolerance band is stated at all. Where this listing does cross-check against itself, it holds: the 125mm length in the bullet text matches the 12.5 centimetres in the dimensions row, and "Output Wattage: 750" matches "Wattage: 750 watts". Everything on this page comes from the Amazon listing as it is written there — we have not tested the unit ourselves.
