2 drives one 1 connector

[tek33]

hi its been awhile since ive posted but have a question . i have a cosmos 1000 case an antec neo power 650 ps wd 400 gb hd . i would like to add another hd but the sata power connector from the psu is 1 power connector split with 2 sata connectors on the end . is it wise to connect 2 hard drives to 1 connector ?

It is fine to hook a hard drive to the second power connector.
