Lian Li Introduces Two New Compact SFX-L Power Supplies
First seen at CES and then again at Computex, Lian Li’s compact form-factor SFX power supplies have finally arrived. The Lian Li PE-550 and PE-750 power supplies are capable of driving multi-GPU gaming systems despite the smaller foot print. The 550W PE-550 is 80-Plus Gold rated with 89.5% efficiency while the 750W PE-750 has a higher 80-Plus Platinum rating with a maximum 92% efficiency. To go with the more discreet size, both PE-550 and PE-750 PSUs utilize a 120mm smart fan that only kicks in when the load goes over 30%, remaining silent during most of its operation.
Bundled with with SFX power supplies is an ATX adapter so it can be installed on any ATX compatible full-sized system as well. These products are currently on display at Gamescom in the CaseKing display at Hall 8.1 Stand B-051 and are also now available in the US from NewEgg.com for $115 and $169 USD.
