Asus P5NSLI - Manual (Page 48)

1-34 Chapter 1: Product introduction
• For a fully configured system, we recommend that you use a power
supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or
later version) and provides a minimum power of 400 W.
• Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot.
• Use of a PSU with a higher power output is recommended when
configuring a system with more power-consuming devices. The
system may become unstable or may not boot up if the power is
inadequate. See Table 2 for details.
