● An additional Peripheral Power Connector *

SL-85DRS adopts an additional Peripheral Power Connector (the power connector that HDD adopts). Users who installed already an ATX2.03 compliant power supply can use the +12V power Connector designed specially for P4 mainboard. For those who use a non ATX2.03 compliant Power Supply (for example, users that upgrade their mainboards from PIII to P4), they can take advantage of the Peripheral Power connector instead of buying a new P4 Power Supply. This design helps users reduce the cost when upgrade their systems.

* For P4 processors faster than 2GHz, we suggest users adopt the ATX 2.03 compliant Power Supply.
