NLX Power Supply Specifications

NLX Power Supply Recommendations Version 1.1 defines the NLX voltage rails and tolerances shown in Table 26-5. An NLX 1.1-compliant power supply must provide these voltages at these tolerances or better. Note that NLX has tighter requirements than ATX on some rails. This document also recommends (but does not require) the power distribution levels listed for a typical 145W sustained (160W peak) power supply. A_min, A_max, and A_peak are as described earlier. NLX power supplies may or may not include the NLX Optional Power Supply Connector described later in this section.
