How long can SATA power cables be?

[Chrisrlyon]

I'm working on a custom PC inside a desk for a little project and was almost set to start it when I realized in my sketchup I placed the PSU on the opposite side of my hard drives. How long could I get away with having my SATA power cables be? With my current design in mind they would need to be up to 1200 mm long. Could I get away with this? It would be one SATA power cable with 2 heads on it.

Will this work or do I need to make some adjustments? Is there any other suggestions anyone has?

SATA doesn't use a lot of current, so voltage drop shouldn't be an issue. For POWER cables, I don't see an issue.

Yes, the way it's setup the data cables to the motherboard will only be about 500 mm which from my understanding should be fine. Thanks for the reply!

They should easily be able yo go a few meters with minimal voltage drops so you will have no issues
