Know before you buy
A fully modular design means every cable can be detached from the power supply. This allows you to use only the cables your specific components require, which significantly reduces clutter and improves airflow inside your case.
The Zero RPM mode keeps the fan completely off during low to medium loads, ensuring silent operation when you're just browsing or doing light tasks. The fan will only spin up automatically once the power supply reaches a higher temperature or load threshold.
Yes, the RM1000 follows the standard ATX form factor. However, please note that it has a depth of 180mm, so you should verify that your specific case has enough clearance for a unit of this size.
The 80 PLUS Gold certification indicates that the unit is at least 87% to 90% efficient at various load levels. This means less energy is wasted as heat, which lowers your electricity costs and keeps your system running cooler.
Yes, the RM1000 includes 8 PCIe connectors, providing ample power and connectivity for high-end gaming rigs or workstations running multiple graphics cards.
Rifle bearings are designed to be quieter and more durable than standard sleeve bearings. They provide a longer lifespan for the fan and help maintain a low noise profile even after years of consistent use.
