| 1346705 | 2013-06-23 23:55:00 | Yeah that's true, but the USB HDD's usually draw a lot more power though don't they? And yes in my experience it's more the thinner cheaper cables, rather than the actual length itself? | Chilling_Silence (9) | ||

Copper wire has a incredibly low resistance, so give the low currents & short cables involved, Its hard to image cable crappy enough to cause issues, but yet there are. :thumbs: |
