Announced back in April, Lian Li has now released a pair of SFX-L power supplies for small form-factor systems with the PE-550 and PE-750. The pair offer fully-modular designs with flat, ribbon-style cables, and carry 80 Plus Gold and Platinum certifications.

The PE-750 power supply

"The PE-550 is 80Plus Gold-rated for a maximum 89.5% efficiency; the PE-750 is 80Plus Platinum-rated for a maximum 92% efficiency. Both use a near-silent 120mm smart fan and minimize noise by operating fanlessly when output power is below 30%. Both PSUs use a single 12V rail design for the best possible stability under heavy system load, matched with myriad protection features to ensure reliable operation."
