Corsair
A 1200 W fully modular ATX 3.1 supply with a side-mounted cable panel, 140 mm FDB fan and 80 PLUS Gold efficiency
Options ATX 3.1 80+ Gold (1200W) Shift
The Corsair RM1200x Shift delivers 1200 W of continuous power in an ATX 3.1 certified unit. It targets builders who need high headroom for multi-GPU systems or workstations with heavy transient loads. Fully modular Type 5 Gen 1 connectors reduce cable clutter inside the case. Cybenetics Gold efficiency and A- noise ratings confirm low waste heat and quiet running.
Verify that your motherboard and graphics cards are compatible with the ATX 3.1 power standard before ordering. The unit supplies one 24-pin ATX connector, two EPS connectors, four 6+2-pin PCIe connectors and sixteen SATA connectors. Ensure your component list matches these quantities and that your case can accommodate a 160 mm deep power supply.
The patented side-facing connector panel lets you plug cables in from the side rather than the rear, simplifying routing in tight compartments. Zero RPM fan mode stops the 140 mm fluid dynamic bearing fan at low and medium loads for silent operation. 105 °C Japanese electrolytic capacitors and Modern Standby support provide stable power and fast wake times.

같은 제품군에서 메모리·쿨러·클럭이 다릅니다 — 결정 전에 비교해 보세요.
The unit is fully modular with Type 5 Gen 1 micro-fit connectors; all required cables ship in the box so nothing extra needs purchasing.
This model delivers 1200 W continuous power; choose it when your GPU and CPU combined draw approaches that level, otherwise a lower-wattage RMx Shift unit will suffice.
It can supply 1200 W continuously at up to 50 °C ambient, meets ATX 3.1 and PCIe 5.1 transient-spike requirements, and holds 80 PLUS Gold plus Cybenetics Gold efficiency with A- noise.
