600W is enough?

[deadeye22]

Hi, i have a z77 V deluxe mobo with an i5 3570K@ 4.2Ghz 2 sticks of 4GB 1600Mhz RAM a sapphore Oc 7950 one DVD drive 4 x250mm case fans 1 x140mm exhaust an ocz agility 3 SSD and a caviar black sata2 HDD. I am already operating fine, i think so. My question is, can i add a 1TB caviar black sata 3 HDD with just a coolermaster silent pro gold 600W power supply?..

P.S. By thr way my cpu cooler i kinda cheap its the TX3 EVO room temp 20-30 celcius prime 95 small FFT 10 minutes 72-74 max temp pretty descent i think

You should be fine.

Another hard drive isn't going to pull that much power. (A second 7950 would be the only single component I would worry about putting you beyond the power supply.)

It should be fine as the drive requires 7W or less.

Those usually estimate high to be on the safe side. But I'm coming up with about 550w on the newegg calculator.

http://www.extreme.outervision.com/psucalculatorlite.jsp comes up with 353W minimum and 403W recommended. I used a 7970 as it doesn't allow selecting an OC 7950 video card and the CPU was overclocked to 4200MHz and 1.35v Vcore. That calculator is quite accurate for quality PSUs.
