Can my PSU handle another HDD?

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

Seagate 2TB BARRACUDA 3.5" SATA-III Hard Drive - 7200RPM 64MB Cache

Coolermaster Hyper 212 Plus Socket 775, 1156,1155 AM2, 1366, AM3 Processor Cooler

An old 250 gig Maxtor for the OS Drive

Intel Core i5 750 2.66GHz Socket LGA1156 8MB L3 Cache Retail Boxed Processor

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

Kingston 4GB (2x2GB) DDR3 1600MHz HyperX Genesis Memory Kit 1.65V CL9

Western Digital WD10EARS 1TB Hard Drive SATAII 5400rpm 64MB Cache - OEM Caviar Green

Sapphire HD 5770 1GB GDDR5 Dual DVI HDMI DisplayPort HDCP PCI-E Graphics Card

M-Audio Revolution sound card

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?

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.
