Go into the Bios and check to see if you get the same reading. Probably your power supply is out of spec and should be replaced. The standard is 3.3 Volts + or - 5%, which would mean a lower limit of 3.14 Volts. How old is your power supply and how old is your motherboard?

Do you know if your Corsair is still under warranty?

You can print a copy of the Proof of Purchase from Newegg and many other e-tailers, at any time.

Borrow a known good PSU from another computer to confirm your diagnosis.

Corsair has a three year warranty, but it is not clear if your power supply is just under three years old or just over three years old. Since you have to pay for return shipping, it may not be worth it to you, even if it is still under warranty.

Corsair is a good brand, but there have been reports of problems with their CX series.

This is a good one, if you don't mind the $20 rebate:
CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

And an extra 10% off with promo code SPECMT10 ends 2/15

Even a GTX 760 only asks for a 500 watt power supply

Personally, I prefer Seasonic. I also suggest buying the highest wattage QUALITY PSU you can afford. It will cost a little more but will run cooler and last longer and you will never wonder if you have enough power. A very cheap insurance policy.

i found that psu at a staples store nearby any thoughts about if its any better or worse than the corsair that was linked


The Antec Basiq Series 550W (BP550 Plus) has a much weaker combined +12Vcontinuous current rating (i.e. 32 Amps) than the Corsair CS550M (SKU# 75-010707 / CP9020076) @ 43 Amps.

Since the a modern system draws most of its power from the +12V rail(s) that is the most important spec you should be looking at.

I would recommend this one over the Corsair since it has better electrical performance and a 7 Year warranty for $64.99 after $20.00 rebate:
