Who it fits
Good fit for
This power supply suits builders who need a reliable, modern platform for mid-range to high-end gaming rigs. The ATX 3.1 standard and included 12V-2x6 cable make it ideal for users with recent NVIDIA or AMD graphics cards that require this specific connector. The 750W output provides enough headroom for most single-GPU setups. If you value clean cable management, the integrated routing channels on the PSU housing will help you hide excess wires. The 135mm fan ensures quiet operation during typical use, making it a good choice for users who prefer a silent PC experience.
Who should skip it
You should look at another option if you need higher efficiency ratings like Gold or Platinum, as this unit is only 80 PLUS Bronze certified. Users requiring more than 750W of power for multi-GPU setups or heavy workstation tasks will find this wattage insufficient. If you prefer a smaller SFX form factor for compact cases, this standard ATX unit will not fit. Additionally, if you do not want a 135mm fan, which is larger than the traditional 120mm option, this model may not suit your acoustic or space preferences. The lack of higher-end features makes it less suitable for extreme overclocking builds.
Verdict: The Lian Li RB 750W Bronze ATX 3.1 Power Supply offers a solid balance of modern connectivity and reliable efficiency. It is a practical choice for builders seeking ATX 3.1 compatibility without paying for higher efficiency tiers.

This design choice helps create a cleaner layout on the back side of your chassis. A tidy cable arrangement also supports better airflow within the system.
Connecting your components requires understanding the power delivery standards. This unit operates on the ATX 3.1 platform. It includes a native 12V-2x6 cable, which is essential for powering modern graphics cards that use the PCIe 5.1 standard. The active PFC feature helps keep power delivery consistent across your build. This stability is useful for both everyday gaming and creator workstations.
During daily use, the 750W output provides sufficient headroom for mid-to-high-end systems. The 80 PLUS Bronze efficiency rating indicates how the unit handles power conversion under typical loads. For noise management, the unit utilizes a 135mm hydraulic-bearing fan. This larger fan size is optimized for low noise. It provides efficient cooling while maintaining quiet operation during typical use. The unit is backed by a 5-year warranty, offering long-term reliability for your investment.
Before You Buy This PSU
You should verify your case supports the ATX form factor before purchasing. The unit measures 5.91 by 3.39 by 5.91 inches, so check internal clearance. Ensure your motherboard and graphics card are compatible with the ATX 3.1 standard and the native 12V-2x6 connector. This eliminates the need for adapters. You may need additional PCIe cables if your GPU requires more than one connection. Regular dust removal keeps the 135mm hydraulic-bearing fan quiet and efficient.
