NA-SAC5
The NA-SAC5 is a fully sleeved S-ATA to 4-pin power adaptor cable. It is compatible with both 3-pin and 4-pin fans and allows them to be powered directly from the power supply’s S-ATA connectors. Combined with the NA-SYC1 y-cables (available separately), it is ideal for powering multiple high-wattage fans without risking damage to the motherboard fan header.
