Can I use my 2.5" drive with bus power alone?
AKiTiO's 2.5-inch hard drive enclosures can be used with bus power, although some hard drives or computers might require an external power adapter, depending on what model is being used.
Note
To assure bus power works with your system, please test it first. Some points which might help; use a short cable (40-50cm), different HDD model (low power consumption), PCI host cards or computers.
