A good deal, but overkill for most servers.  The only reason you would need a PSU this beefy is if you want to run 20+ 7200 RPM drives.  If you plan on using green drives, then I recommend the TX650 V2 instead.

I'm Planning to build a 4224 with 24 drives (once unraid supports that many).  I already have 16 drives which are all Hitachi 7K2000 drives.  While these are 7,200RPM drives Hitachi specs show the power at 2.0A and not 3A like has been suggested for faster drives (should I believe Hitachi?).  I'm waiting for the next great sale on the 5K3000 drives which I'll likely use for the remaining eight drives.   I figured 650 might be cutting it close and was planning on a 750 when I saw this deal on the 850.  I'm just debating if I should pull the trigger or wait for a better deal, possibly on a smaller unit.

I just bought one for a 21 drive Green Monster.  Upgrade at no additional charge.

In that case this PSU sounds appropriate for your needs.  The 750 would be fine too if you find it on sale.

Thanks.  Decided to pull the trigger on Monday morning only to find the deal had expired.  I see the 750 can be had for $84 AR today so I think I'll just go with that.  Hopefully the purchase will trigger the 20% off code for cases code that I wasn't lucky enough to receive.
