Extra HDD for my 600w PSU?

[gowthaman400]

Hello,
My PC config is
iBall Sprinter 600w SMPS
AMD Phenom II X4 3.0ghz
4GB DDR3,
Nvidia XFX 9500GT 1GB DDR2,
1TB HDD
250GB HDD,
160GB HDD
and Optical drive.

The question is can i add onemore 1TB HDD under 600w SMPS? I've already connected 3 hdds and there are more power connectors and sata ports left.

Should work just fine. HDD do not pull much load.

HDDs use less than 10 watts when being actively accessed, 1-3 watts on standby. One more HDD shouldn't put any appreciable strain on your PSU.
