I am kinda new to PSUs. I have been having problems with my Hard drives (like bad sectors etc) ever since i bought my 3rd 500GB drive and connected to the system. Now i suspect my PSU is to be blamed here for those hard drive failures, as scanning the drives with 'HD Sentinal' indicated that the bad sectors were caused when the hard drive tried to spin-up and this usually happens due to weak power supply.
Here are my voltage values from Everest Ultimate Edition:
CPU Core 1.18 V
+2.5 V 1.95 V
+3.3 V 3.38 V
+5 V 4.95 V
+12 V 8.45 V
+5 V Standby 5.19 V
VBAT Battery 3.04 V
After reading some threads here, i am guessing that +12V should be around 11.4 Volts (with 5% tolerence). But mine is only around 8.45 Volts. Is this a big problem? Is PSU really the cause of all the hard drive errors? I don't use any GFX card yet and have three 500GB drives connected. My PSU brand is iBall.
If yes, then please suggest a entry level good PSU. I've narrowed down my choice to:
Cooler Master eXtreme Power Plus 460W

Corsair cx400w

PS: I would be using following components in my system
C2D E6850 3.0GHz
3 x Sata HDDs (might get one more in near future)
1 x DVD-RW Drive
1 x GFX card (like 4850 or other ATI 5 series) that i am planning to buy in near future. I dont have any currently, have been using onboard G33.
Any help would be appreciated,
Thanx.

Dont use software to check your voltages, either check with bios(easiest) or a digital multimeter(100% accurate), most of the software i have used to check my voltages tells me my 3.3V rail is -7.6ish, i havent seen a program yet that reads voltages right. If your PSU was only at 8.45V on the 12V rail it wouldnt even run, and it has 2.5V rail with which im not familar. Double check using a DMM or in bios if you dont have one, post those voltages, if they are still off it might be good to switch.
Now if you are planning to upgrade to a 4850 then consider something a bit more powerful than either of those two, a good 500 or 550 for a higher power card, a 450 would be fine for a lower power card like a 4770 or 5770.

Thanks for your quick reply.
Well, i dont have a DMM so i tried checking with BIOS, but under 'PC Health Status' option in the bios, it simply says 'OK' in front of +12v and +3.3v entries and doesn't show any voltage values. I have a Gigabyte GA-G33M-S2H mobo.
And about the new PSU, unfortunately, my budget is limiting my options, so please suggest strictly among those two.
The corsair has single +12v rail with 30A while the cooler master has two +12v rails with 18A each.

Also, i just tried the Power Reqirements Calculator at www.corsair.com with following parameters
1 x C2D (not overclocked)
1 x HD4850
4 x HDDs
and it still recommends cx400w, so i guess i can manage with 400-460W. But which one among those two?

Of those two the 400CX is the better choice, the coolermaster only has 26A combined on its 12V rails vs the corsair's 30A. The cooler master also doesnt have APFC and isnt 80+ certified so its an older design and less efficient, we also dont know if it passed a 100% load test.Hmm, thanks for your opinion. I have two votes for cx400w now.
