I recently moved from the US to the UK and want to use my desktop with a Corsair RM1000e (2025) 1000 W power supply. Can I simply replace the US power cable with a UK cable, or do I need a voltage converter or transformer? I'd also like to know whether using a new cable is safer than using a plug adapter. The PC includes a high-end CPU, graphics card, and several other components, so I want to make sure the UK's 230–240 V, 50 Hz supply won't cause problems. I'll verify the ratings on the exact power-supply model before connecting it.

Double-check the exact model rather than relying only on the product name. Some older power supplies had a manual 115/230 V selector, while newer units usually switch automatically. If yours lists 100–240 V input and has no selector, just use the correct UK cable. Buy a properly rated cable from a reputable electrical or computer supplier.
You don’t need a converter or long-term plug adapter if the PSU supports 100–240 V. A UK-plugged IEC C13 cable is the simplest and safest option, and the 50 Hz UK supply is supported by this type of modern PC power supply.
The RM1000e is designed for wide-range input, typically 100–240 V AC, so it should work on UK mains without a transformer. Confirm that the label on your exact unit says 100–240 V, then buy a proper UK mains lead with an IEC C13 connector—the common PC cable often called a “kettle lead.”
That clears it up—thanks! I’ll check the label and get a UK IEC C13 cable.
Right—the important part is the input rating printed on the PSU. Not every power supply switches automatically, so checking first is still worthwhile.
