¥ 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.

¥When using two graphics cards, do not forget to connect the 4-pin ATX +12 V power plug to the EZ Plugª; otherwise, the system will be unstable. See page 6-6 for details.

¥To support an Intel¨ Dual-Core CPU Extreme Edition up to 3.2 GHz, make sure that the PSU can provide at least 16 A and 19 A peak on the +12V_2 lead. Refer to the vendors list on Table 1 for details.

¥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.
