What PSU are you using for 20+ drives?

[Rajahal]

I am trying to determine which PSU I should recommend for the 20 Drive Beast.  Theoretically, a 450 W should be enough.  However, I haven't been able to test that personally since I don't have 20 drives.  What are you using?  Please post the make and model as well, not just the wattage.  I'm especially interested in seeing if anyone is using a small PSU in the 450 W to 650 W range.  If you are taking any extra steps to keep your power needs low (such as using only green drives) please post that as well.  Thanks!

Corsair HX620

The manufacture did state it could support 20 drives even though it has 3 Rails.

It is documented that the rails can share power for surges.

 

I have 10 green drives, 5 7200 RPM drives, 2 Drive raid0/raid1 parity cache.  4 Sata controllers. 8GB & 2.4ghz Core 2 Duo. an IPMI card. I do not have any issues to report.

One vote for the Antec 620 Neo.

 

EDIT: If you are asking for the wiki go for the Corsair 650W.
