CORSAIR RM750e ATX 3.1 PCIe 5.1 Ready Fully Modular 750W Power Supply – 12V-2x6 Cable Included, Cybenetics Gold Efficiency, 105°C-Rated Capacitors, Modern Standby Mode – Black vs Lian Li Strimer Wireless 24-Pin RGB Motherboard Power Extension Cable with Wireless Controller, 2.4GHz Wireless Lighting Control, 315mm (12.4 in) 12 Light Guides, Controller (Included) (PW24-1W-T)

Price Comparison: $89.99 vs. $69.99

The CORSAIR RM750e is about 28% more expensive than the Lian Li Strimer Wireless, priced at $89.99 compared to $69.99. This $20 price gap reflects a fundamental difference in function: the RM750e is a high-performance power supply unit (PSU), while the Strimer Wireless is an RGB lighting extension cable. The RM750e’s higher cost aligns with its role as a core system component responsible for delivering stable, efficient power to all internal hardware. In contrast, the Strimer Wireless serves a niche aesthetic purpose—extending and controlling RGB lighting on motherboards—making its lower price appropriate for its specialized use case.

Core Functionality: Power Delivery vs. Lighting Control

The CORSAIR RM750e functions as a complete power delivery system, designed to supply consistent electricity to every component in a PC build. It supports modern standards like ATX 3.1 and PCIe 5.1, ensuring compatibility with high-end GPUs and future-proofing the system. Conversely, the Lian Li Strimer Wireless is not a power supply but an extension cable for motherboard RGB lighting. It enables wireless control of RGB effects via a dedicated controller and does not provide electrical power to any system components. The RM750e ensures operational stability, while the Strimer Wireless enhances visual appeal without affecting system performance.

Build Quality & Design Philosophy

The RM750e emphasizes reliability and longevity with industrial-grade, 105°C-rated capacitors and a seven-year warranty, reflecting its role as a critical hardware component. Its fully modular design allows users to connect only necessary cables, improving airflow and reducing clutter. The Strimer Wireless, by contrast, focuses on aesthetics and integration with other Lian Li devices. It features a 315mm-long RGB cable with 12 light guides that extend coverage to the sides for a more immersive effect. While both products are built for modern systems, the RM750e prioritizes durability and efficiency, whereas the Strimer Wireless prioritizes visual customization.

Compatibility and System Integration

The RM750e is compatible with standard ATX, mATX, and ITX motherboards through its 24-pin connector and includes multiple PCIe and SATA connectors to support current and future hardware. Its inclusion of a native 12V-2x6 cable specifically addresses PCIe 5.1 power demands. The Strimer Wireless is also compatible with ATX, mATX, and ITX motherboards, connecting via a standard 24-pin header. However, it requires proper alignment of the connector latch; if misaligned, users may need to adjust the cable comb slightly backward. While both integrate into mainstream cases, the RM750e’s compatibility spans the full range of PC power needs, unlike the Strimer Wireless, which is limited to lighting control.

Performance Features and Efficiency

The RM750e delivers Cybenetics Gold efficiency, meaning it converts a high percentage of input power into usable output with minimal waste, contributing to energy savings and reduced heat. It features a 120mm rifle bearing fan with a calculated fan curve to keep noise low under load. The Strimer Wireless has no performance metrics related to power delivery or thermal management. Instead, it uses 2.4GHz wireless technology for responsive, customizable RGB lighting control. Its main performance feature is the ability to sync with other Lian Li devices through the L-Connect 3 software, enabling real-time monitoring of CPU/GPU temperature and fan speeds.

Included Accessories and Setup Experience

The RM750e comes with a full complement of cables: one 24-pin ATX, two 8-pin EPS, one 8-pin PCIe, one 600W 12V-2x6, one 12V-2x6 to dual 8-pin PCIe, six SATA, and two PATA connectors. These are sufficient for most builds. The Strimer Wireless includes the 24-pin extension cable and a wireless controller essential for operation. No additional software is mentioned in the product description, though the L-Connect 3 software is referenced in features. The RM750e’s setup is straightforward due to its modular design, while the Strimer Wireless requires careful alignment during installation to ensure proper connection.

Warranty and Longevity

The RM750e offers a seven-year warranty, a strong indicator of Corsair’s confidence in its build quality and long-term reliability. This warranty covers potential failures of the PSU over time, which is critical given its central role in the system. The Strimer Wireless does not list a warranty duration in the provided data, suggesting either a shorter or unspecified guarantee. Given that it is a peripheral accessory rather than a core component, the lack of a stated warranty is expected. Still, the RM750e’s extended coverage underscores its importance as a foundational part of the PC.

Which should you buy?

Choose the CORSAIR RM750e if you need a reliable, efficient, and future-ready power supply for your PC build, especially one supporting high-end GPUs or modern ATX 3.1 systems. At $89.99, it’s a premium investment for performance and longevity. Opt for the Lian Li Strimer Wireless only if you’re looking to expand and wirelessly control RGB lighting on your motherboard with a 2.4GHz controller, particularly if you already own other Lian Li devices. At $69.99, it’s a compelling choice for aesthetic upgrades but serves no functional role in powering your system. The RM750e is essential; the Strimer Wireless is optional.
