2gb ddr2 RAM Transcend
nvidia zotac gt630 2 gb graphic card
seagate 160 gb hard drive and 1 Tb Western digital (newly added -facing probs with this)

Do you already have the Mercury or are you considering buying it?
Can find little info on Mercury PSUs so suspect they are el-cheapo generic.
When looking at powersupplies, the total wattage rating is not the measure to take most notice of. Post back with detailed AMP ratings for each Voltage rail.
If adding the 1TB hard drive is causing you problems then outline what kind of problems. It may be you are overloading the 12V rail with the extra drive.

Look for a quality PSU with a single 12V rail of 30Amps. What to get depends on availability where you are in the world.

I had this mercury when I first bought this system 5 years ago.
Input- voltage(115/230v) current (8A/4A) frequency(50Hz/60Hz)
output +3.3 +5v +12v -5v -12 5VSB
18A 23A 17A 0.3A 0.8A 2.0A

Hard disk probs : It keeps getting struck while reading a file few times. downloading,copying to or from the drive freezes for some time and then continues..
I did a diagnostic test with western digital diagnostic tool as well chkdsk/r,nothing wrong found.

✔ Best Answer
Typical of cheaply built powersupplies. The rated amps on the 3.3V and 5V rails are way over what any system would need and the 12V which is what the system mostly relies on is light on for the load you are now placing on it. Shop for a new powersupply rated @30amps on 12V rail.

Mercury build crap components(cases, psu & boards). Shop for quality brand unit from Corsair(go for builder series), thermaltake, antec, rosewill etc.

32Amps on the 12Volt Rail. Reasonable price.
