I got the 2.8A number from the datasheet of one of my 500GB drives. They're all different models, it's just an estimate.

Unfortunately I don't have fancy 3ware RAID controllers or any enterprise drives. They're all desktop drives and I can't find any way to stagger spinup on them with the controllers I do have. I prefer to let Linux handle the RAID which has its advantages. This is one of the disadvantages.

It's not a hard drive it's 12 hard drives. I don't know why you don't think CPUs don't get used when you turn on a computer.

This is how much power the drives are specified to use in order to START spinning and it should happen every time I turn on the computer for a few seconds. They use much less power once spinning, max about 13Wx12=156W.

Edit: Also I already have a 1500VA UPS for it.

I think this PSU will probably be best for your server. It can deliver over 600W continuous power without breaking a sweat, so powering your system should be no problem for it.

My 3ware cards are both set to 2s stagger on both of my 4 drive raid 5 arrays.
Yup.... this would be ideal.

The peak power is at spin up and definitely uses more than .5A.

You can use a HBA/SATA/RAID controller but still implement software RAID.


Your main issue will be the +5v rail since all modern PSUs have beefier +12v rails. If you do not want to invest in a controller card, look for a quaility PSU with a large +5v rail.

Why spend the premium on a fanless PSU when it still requires forced airflow? The case will still require fans.

I could... but my current controller set up is working fine (except for this) and I don't really want to mess with it. Also a twelve port+ HBA is going to run more than an extra few hundred watts on a PSU I would guess. Or I could get a 4-port one that supports port multipliers but I'm not sure whether the port multipliers would interfere with staggered spinup or not.

That spinup calculation was based on a Seagate datasheet which only specified draw for the 12V rail. The other drives I'm having a hard time finding such specific data... How many 5V amps do you think I'll need?

I never said it had to be fanless, she can go with a X-560 instead if she wants. Just showing what types of decent PSUs she should look out for that would provide clean and stable power, which is pretty critical for a file server.

You don't need all your HDDs on stagger spinup... just a few.

Hmmm.... I believe HDDs use +12v for the motor and +5v for the logic board. If that is true, the increased spinup power draw would only be on the +12v.


You might want to replace those 500GB HDDs in addition to getting a decent PSU... 500-600w, I would estimate. In use, your system probably draws something like 400w though. Do you have Kill-A-Watt avaliable?

Well what controller would you suggest? Has to be one that can be set up not to do raid and not put any weird superblocks or format the drives specially or anything that would ruin my existing partitioning. Needs to have either port multiplier support or at least 6 ports (leaving 6 drives connected to the mobo directly.)

It seems like every PSU I look at has 25A on the 5V+3.3V combined. Even gigantic 1200W ones.

I am working on replacing those 500GB HDDs! Probably when I run out of space again.

I do have a Kill-A-Watt around here somewhere... not sure where it is at the moment. I figure it would be hard to get a good spinup read due to capacitors and inductors smoothing things out. Also would it be okay to put the Kill-A-Watt between the UPS and the wall or would that mess up the readings?

Think about that for a moment.



here's a 3ware 12 port card. No heatsinks, no fans, no pci-e or "molex" connections. Most of these cards will only use a few watts worst case, and that would be if you were doing something like rebuilding a degraded SSD based raid 5 array.

I think you would be very surprised at how little power you need to run that.

I suggest getting a Kill-A-Watt for testing purposes if you are concerned.

If you opt for a high-rated brand such as a Seasonic (or many of the rebranded versions, some Antec, lots of Corsair, etc) you will typically be able to pull more than it's rated for during your spin-up without effecting the life of the PSU.

I suggest these models-

Seasonic SS-460 Fanless (if you're going for discrete):

Or maybe this model if you don't care so much about the noise and want a bit more headroom for upgrades down the line:
