Can my PSU handle another HDD?

[Xirix]

I've recently gotten a new 2TB drive for recording purposes, had to stick it in the floppy drive bay as my tower only technically supports 3 harddrives, whenever I use it I disconnect one of my storage drives and use the data cable from that.

But that's starting to get a little inconvenient, so I wanted to check if my PSU will be able to handle having the fourth HDD in without things going wrong.

The new HDD is a 'Seagate 2TB BARRACUDA 3.5" SATA-III Hard Drive - 7200RPM 64MB Cache'

The contents of my PC other than that are as follows.

G.Skill 8GB (2x4GB) DDR3 1600Mhz RipjawsX Memory Kit CL9 (9-9-9-24) 1.5V

Asus P7P55D-E LX P55 Socket 1156 8 Channel Audio ATX Motherboard

My PSU says OCZ700 on the sticker, so I assume it's a 700 watt PSU (I don't have the box anymore).

Assuming it's okay to add another HDD, I wouldn't necessarly need it on all the time, are there options in Windows 7 to have it turn off/go idle after so many minutes of not being accessed?

Yes it can easily handle a couple of more HDD's.

yes, it could defenitely hold more HDDS. Probably even 4 more if you had the connectors. HDDS are reasonably power efficent

I have three SATA hard drives, one SSD drive, and a DVD recorder drive all powered by a Dell 460 watt power supply. I don't think drives take much power at all these days.

You can defintely set drives to spin down/power down after X minutes of inactivity in the Windows power management settings. I sometimes hear one spin up.

Thanks for the quick answers, so can I tell just the one HDD to have power management settings? I had a brief look on google and apparently it's all HDDs or none?

I think it's all or none. So use power management for all of them. If a drive hasn't been accessed in 30 minutes (or 60 minutes or whatever you set), then there's no reason not to spin it down. If it's a drive you are frequently accessing, then it won't power down. It's not like a light switch; it's all automatic based on how recently the disk was used. Most of my HDDs are used for backups. They stay powered down most of the time.
