SATA Drive Limit Per Cable

post #1 of 23
Thread Starter 
Hey OCN,

I am creating custom cables for my Corsair HX-650 V2 80 PLUS Gold Power Supply and I was wondering what the drive limit would be for each SATA power cable? I am out of PSU connections so I would want to connect 5x 2TB drives and 1x 3TB drives all on the one cable....hope that's possible :/? Your feedback would be greatly appreciated

You could probably fit 3(Most ive ever done) But if you have the wattage headroom, I would say about 7-9 maybe

What about Molex? Run a few adopters of that?

Its for "Silent But Deadly" if you need the specs - I don't know a great deal about wattage just yet.


I have molex cables laying around I believe, so I would just get adaptors to go from Molex to Sata? How many could I have per cable if that I went that way?

Drives don't exactly draw alot of power, You could and should be quite safe with 10 off the one cable, However if i were you i would stagger the turn on if that was the case.

How would I stagger the turn on? I don't really plan on turning this off a great deal as it is a HTPC and I will probably use Flexraid software to manage RAID

Are you going to be using splitters? Slightly confused by your question.

No spilters. PSU > HDD > HDD > HDD > HDD > HDD > HDD


Just a normal PSU > Sata Power cable smile.gif Like below

You can use every single connector it has.

I am wanting to create a custom cable for 6 HDD so I would be basically doubling the included cable from handling 3 HDD to handle 6 HDD. Would this be an issue?
post #10 of 23
You should be just fine. That's like 40W, that's nothing.
