In-Depth Information
Intel originally introduced the LFX12V (low profile form factor) power supply in April 2004. It's
designed for ultra-small BTX systems of about 6-9 liters in volume, primarily using picoBTX or
nanoBTX motherboards.
LFX12V power supplies are designed to deliver nominal power output capabilities of 180-260
watts, which is ideal for the tiny systems for which they are designed. LFX12V supplies include an
internal 60mm fan, which is 20mm smaller than that of the CFX12V design. Similar to the CFX12V
fan, it is usually thermostatically controlled to ensure quiet operation while still providing adequate
cooling. The shape of the supply includes a ledge such that part of the supply can extend over the
motherboard, reducing the overall size of the system (see
Figure 18.12
). The dimensions of the
LFX12V form factor are shown in
