Hello,
Previously i am using a zebronics psu
Which says 450w on it for running a _intel i5 3470
_intel motherboard DH61BF
_hard disk segate 1 tb


When i added another 1 tb hard drive segate.
The system stopped functioning
It will be struck on the strtup where the mother board series name comes
And then the sound comes from the hard drive as like a cd is struck.

Which psu should i buy for this pc running two harddrives
Thers no graphic card installed


How many watts psu should i buy no for my pc to run two hard drives
