disk drive power connector

Hi,

Can somebody tell me that when (for what kind of applications may be) should we connect the device disk drive power connector in a PCIe 6353. In the device installion guide , its written "optional".

Thanks in advance,

Arijit

1. (Optional) On NI M and X Series PCI Express devices, connect the PC and the device disk drive power connectors. The disk drive power connector is a 4-pin hard drive connector on PCI Express devices that, when connected, increases the current the device can supply on the +5 V terminal. For most applications, it is not necessary to install the disk drive power connector. However, you should install the disk drive power connector in either of the following situations:
   • You need more power than listed in the device specifications
   • You are using an SCC accessory without an external power supply, such as the SC-2345

I am also setting up pcie-6353. Unfortunately, I don't find any disk power connector in my Dell T5810 computer. I guess that I probably need to have an extension connector. Where should I get that?
