I didn't expect this to happen, and I'm not sure how worried I should be, even though I'm slightly freaking out.
I recently bought a Corsair 750 CXM and until now have had no issues. My 3.3 rail voltage keeps dropping below 3, and I get a warning every time it goes below 2.97 and its fluctuating between 2.9 and 2.954 when it I do get the warnings.


I'm using Win 7, 
CPU is AMD FX6300
RAM is 8gb 1600 KVR

Now it just went back up to 3.1

I've got a 120gb SSD a 320GB HDD and a 500GB HDD, and an HP ODD

My other voltages look fine, 5V is at 4.992 12V at 11.994, VDDA (assuming thats 2.5) is at 2.52, Vcore at .852
Now my 3.3 is steady at 3.12

i hope its not a big issue...if it is i'll had to try to find the receipt from best buy or i'll have to register the product with corsair and have it returned or something..

Edit: Big issue evidently. just crashed twice, giving no reason or blue screen. rushing to type this before it crashes again. hopefully i can find the receipt for a cash refund.

this sucksss

I also noticed my cpu coltage is jumping upwards of 1.4 when i've never seen it go over 1.0, being as it usually hangs below 1... i dont know whats going on

You should rma or return that psu. The voltages should stay within 5% of the specified target 3.135 is the lowest you would accept. Very likely your problems are tied to that low voltage.

+3.3VDC ± 5% +3.135 VDC +3.465 VDC



If I am helping you with a problem and I have not responded within 48 hours please send me a PM.
