GixCore Editorial
Product overview
Released in April 2018 as part of Corsair’s RMx (2018) refresh, the RM750x (SKU CP‑9020179, platform RPS0109) is a 750 W, 80 Plus Gold, fully modular ATX unit in a compact 160 mm chassis with a 10‑year warranty. It follows ATX12V v2.4/EPS12V 2.92 and uses standard 8‑pin PCIe outputs; there’s no native 12VHPWR or ATX 3.0 compliance.
Positioned in the high_end tier, it exists to offer quiet, dependable 750 W power with tidy cabling at a mainstream price point below Platinum/Titanium lines. It’s a solid pick for mid-range gaming rigs with some headroom for CPU/GPU boosting or light overclocking, and it fits easily in most ATX cases. A Zero RPM fan mode helps keep acoustics low at idle and moderate loads.
