Lian Li's $70 Bronze PSU Surprises with Near-Silver Efficiency and ATX 3.1
The Lian Li RBO750B is a non-modular 750W power supply with an 80 PLUS Bronze rating, but it achieves efficiency close to Silver. It includes native 12V-2x6 support and a quiet 135mm fan, all for $69.99. The review gives it 90%, praising its premium capacitors and three-sided cable routing despite the lack of modularity.
The RBO750B pairs its 80 PLUS Bronze certification with a Toshin Kogyo 420V/470µF primary capacitor rated for 105°C operation, a component choice typically reserved for pricier units. Its Hong Hao 135mm fan and full protection suite—including OPP, OVP, SCP, OCP, UVP, and OTP—round out a package that also carries a 10-year warranty, an unusually long commitment for a budget-oriented supply.
Despite skipping modular cabling, Lian Li's three-sided cable routing design helps builders manage the fixed wires more cleanly inside standard ATX cases. The unit's native 12V-2x6 connector means modern GPUs can be powered without adapter dongles, while its near-Silver efficiency results suggest the Bronze rating undersells real-world performance at this $69.99 price point.
This budget PSU could nudge entry-level PC builders toward higher-quality power delivery without the usual cost penalty, potentially raising baseline reliability in affordable gaming rigs. Its near-Silver efficiency may also translate to modest long-term energy savings for users running systems daily, though the non-modular design could limit appeal for enthusiasts prioritizing cable aesthetics. As ATX 3.1 adoption grows, affordable units like this may accelerate the transition away from older power standards.
