Corsair RM1000e 1000 Watt 80 Plus Gold ATX 3.0 SMPS

The Corsair RM1000e delivers 1000 watts of continuous power in a fully modular ATX 3.0 form factor, making it a capable choice for high-end gaming and workstation builds that demand clean, stable power delivery. Its fully modular cable design means you connect only the cables your build requires, reducing clutter inside the chassis and improving airflow across other components. The RM1000e carries the 80 Plus Gold efficiency certification, indicating it converts mains power to usable DC power with reduced energy loss compared to lower-rated units — this translates to less heat generated inside your case during sustained operation. The ATX 3.0 standard compliance ensures compatibility with the latest generation of graphics cards, which can place large, instantaneous power demands on the supply during GPU transient loads; ATX 3.0 specifies tighter voltage regulation tolerances and updated PCIe power connector standards to accommodate these spikes. The unit is categorised as a gaming-grade power supply and carries the Corsair RMe series designation, which positions it within Corsair's value-focused modular lineup. It ships with GTIN 840006699750, confirming product authenticity against manufacturer records. Builds that would benefit from this PSU include those pairing a current-generation discrete GPU with a high-core-count CPU, where combined sustained power draw approaches or exceeds 700–800 watts and headroom for overclocking or multi-GPU scenarios is desirable. — Verified Specifications — • Model: RM1000e (SKU: CP-9020264-IN) • Rated Output: 1000W continuous • Efficiency Rating: 80 Plus Gold • ATX Standard: ATX 3.0 • Modular Design: Fully Modular • GTIN / EAN-UPC: 840006699750 • Brand: Corsair • Form Factor: ATX • Segment: Gaming Note: Fan noise rating, rail topology (single vs. multi-rail), warranty period, cable length, and connector count are not confirmed in available source data and have been omitted from this listing.
