HDD Power cable maximum length

post #1 of 4
Thread Starter 
Hi guys,

So as the topic says, is there a limit on the length of the power cable running from the PSU to the HDD? Basically I'm building a custom desk in which my PC will go, but I will need to run custom made power cables to the HDD's and DVD writers etc. I have read that the length of SATA cables do not matter, but I need to know about the power.

Thanks alot!

Nope, as far as I know, the length of the cables don't matter thumb.gif

Actually, SATA data cables are limited to one meter (see this from Seagate). SATA power cables are limited by length, wire size, and the number of drives on the cable. The larger the wire, the longer the cable can be and/or the larger the number of drives can be on the cable without voltage drop issues.
