Hi guys,

I've got the CORSAIR HX Series CMPSU-650HX 650W and am running with 22 drives right now (one is an SSD for my cache drive).  Of those 22 drives, only one is currently a 7200RPM drive (my parity drive).  I want to start upgrading to some 3TB drives but can't find any decent green ones.  Will this PSU handle (5) ST3000DM001 (1 parity, 2 to replace (2) 1TB WD Green drives, 2 to add to the array).

 

Thx!

 

 

The ST3000DM001 is rated for 2A on startup.

You PSU is a single 12V rail, rated at 52A.

 

...I'd take 3A out for mobo, CPU+RAM for startup...plus 3A for all three of your M1015 (rated 7W each)

That makes out to a total of 46A to drive the disks...good for 22 drives of the ST3000DM001 with 2A each model...and a spare/reserve of 2A.

 

You could also try staggered spinup with your M1015...but I actually don't know if this applies to a total

cold boot/startup, see: http://hardforum.com/showpost.php?p=1036260651&postcount=51

Many thx!

 

So I should be good with a mix of

 

Samsung HD154UI

Hitachi HDS5C3020ALA632

Samsung HD204UI

Western Digital WD15EADS

...just check the startup power draw from the drive specs.

The one from seagate for your model is here: http://www.seagate.com/files/staticfiles/docs/pdf/datasheet/disc/barracuda-ds1737-1-1111us.pdf

 

...get the specs from the other drives you already have or plan to employ.

 

...from there, it is simple maths.

As said, I think you have 46A(mps) total to spend for drives in your array with that PSU.
