Power supply Lian Li RB750B Black 750W 80 Plus Bronze PCIe 5.1, ATX 3.1

This Lian Li RB750B Black 750W power supply is a stable foundation for mid-range to more serious gaming or workstation builds. With 750W power and an 80+ Bronze certification, you get good efficiency for systems with a more demanding CPU and a modern GPU. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 guarantees compatibility with the new generation of graphics cards via the included 12V-2x6 connector. Although it is not modular, this power supply is aimed at people looking for reliability and current standards without unnecessary extras.

What you get: 750W is fully sufficient for a combination of a powerful multi-core processor and a solid graphics card, including models requiring PCIe 5.x power via the 12V-2x6 connector. The 80+ Bronze certification and up to 88% efficiency mean less wasted energy in the form of heat and a quieter fan under normal load. The large 135mm FDB fan (Fluid Dynamic Bearing) ensures quieter operation and a longer life compared to more basic fan bearings. With several SATA, Molex and EPS connectors, you can power both modern SSD/HDD and older hardware or peripherals without drama. The universal input 100 – 240 VAC allows trouble-free operation in different electrical installations.

• 750W Power – sufficient for serious gaming or a work configuration with a powerful CPU and mid to high-range GPU without worrying about a lack of power.
• 80+ Bronze certification and up to 88% efficiency – less heat and lower power consumption under typical load, which also reflects in quieter operation.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 support – ready for modern graphics cards and future upgrades, without the need for adapters and compromises.
• 12V-2x6 PCIe 5.x Connector – direct power for new generation GPUs with a single cable, plus 1 x PCI-Express 6+2-pin for wider compatibility.
• Two 4+4-pin ATX/EPS connectors – stable power for modern motherboards and more power-hungry processors, including platforms with more serious VRM.
• 5 x SATA + Molex / 4-pin connectors – enough connections for SSD, HDD, fan hubs, and older equipment in more loaded cases.
• 135mm FDB Fan – better balance between cooling and noise, suitable for 24/7 operation and longer power supply life.
• ATX Format and Active PFC – standard size for most cases and higher quality power management from the network for more stable voltages.

Who is it suitable for: this power supply is a logical choice if you are building a mid to high-range gaming PC or a productive machine with a modern graphics card and want to be ready for PCIe Gen 5.x. It is also suitable for heavier configurations with lots of storage and additional devices, as long as you do not insist on modular cabling and maximum efficiency from higher-class certifications.

The combination of 750W, ATX 3.1 / PCIe 5.1 support and a quiet 135mm FDB fan makes it a practical choice if you are looking for a current and reliable power supply without unnecessary luxury. You get a solid foundation for your current build with good prospects for future upgrades.
