This article covers Corsair RM750x (2018) Netzteil 750 W ATX Schwarz.

Overview

The Corsair RM750x (2018) is a well-respected 750W ATX power supply from Corsair's RMx series, known for its balance of efficiency, low noise, and build quality. It carries an 80 PLUS Gold certification, ensuring high efficiency under typical loads. The fully modular cable design lets you connect only the cables you need, keeping your build clean and improving airflow. A zero RPM fan mode keeps the 135mm fan off during low to medium load, making this PSU nearly silent in everyday use. This unit is a solid mid-to-high-end choice for gamers, creators, and system builders who prioritize reliability.

Compatibility Guide

This PSU conforms to the standard ATX form factor and fits almost any ATX mid-tower or full-tower case. It provides two EPS 8-pin connectors for CPU power, supporting high-end motherboards with dual CPU power headers. Multiple PCIe 6+2-pin connectors are available, accommodating up to two mid-range graphics cards. Note that the RM750x (2018) lacks a native 12VHPWR (12V-2x6) connector, so you'll need to use the provided adapter cables for modern GeForce RTX 40-series GPUs. Cable lengths are generous — around 600mm for the main ATX cable — so routing in larger cases is not an issue.

Product Info

Originally launched in 2018, the Corsair RM750x (2018) remains widely available through major retailers. In Japan, typical street prices range from ¥12,000 to ¥20,000, though some third‑party sellers on list it much higher. The unit carries a 7-year warranty and uses 105°C Japanese capacitors throughout for long-term durability. It is an 80 PLUS Gold certified unit, achieving up to 90% efficiency at typical loads. Positioned as a mid-to-high-end offering, it competes well with other Gold‑rated fully modular PSUs from Seasonic, be quiet!, and EVGA.

Best Use Cases

  1. Quiet PC Builders The zero‑RPM fan mode means the fan stays off under low and medium loads, making this PSU perfect for home theater or office PCs where silence matters. For full-time high-load or fanless builds, consider a fanless model or a larger unit with even lower fan speeds. 2. First‑Time PC Builders Fully modular cabling simplifies cable management — only plug in the cables you need. This, combined with Corsair's strong reputation for reliability, makes the RM750x a safe, easy choice for beginners. If your budget allows, look at newer ATX 3.0 units for future‑proofing. 3. Mid‑Range Gaming Rigs Pair this with an RTX 4060 Ti or RX 7700 XT and a Ryzen 5 or Core i5 processor for a well‑balanced 1440p gaming PC. The 750W capacity leaves enough headroom for moderate overclocking. For an RTX 4080 or higher, consider jumping to the 850W version.

Things to Consider

This unit does not support the ATX 3.0 standard or the 12VHPWR connector, which means adapters are required for newer Nvidia GPUs. Prices on can be inflated well above MSRP, so shop around. The RM750x (2018) is a proven design, but newer models in the RMx lineup (like the RM750x (2021)) offer improved transient response and a slightly refined fan curve. Under sustained full load, the 135mm fan is audible — it's not completely silent. If you need native 12VHPWR support or a more compact size, look at Corsair's RMx Shift series or newer ATX 3.0 alternatives. ## FAQ
Q: Can this PSU power an RTX 4070? A: Yes, it can. The RM750x (2018) has adequate PCIe power cables and 750W capacity. You will need the adapter cable included with the GPU to connect a 12VHPWR card. Q: How long is the warranty? A: Corsair offers a 7-year warranty on the RMx series. Be sure to register the product after purchase to activate full coverage. Q: Should I buy the 750W or the 850W version? A: For a typical mid-range build (e.g., Ryzen 5 + RTX 4060 Ti), 750W is plenty. If you plan to upgrade to a high-end GPU or overclock heavily, the RM850x provides more headroom and is often only slightly more expensive.
