Corsair CX430 CMPSU-430CX V2

+3.3V - 20A --- 120W shared with +5V
+5V - 20A
+12V - 28A --- 336W
-12V - .8A - 9.6W
+5Vsb - 3A - 14w

Total power 430w

I put in the powersupply above, and im getting 11.664v on +12v, +5v 4.838v, and +3.3v 2.892v.. and I haven't even put the graphics card in.., is this safe or should I look for another powersupply?

That is more than enough PSU for that little card.

Software voltage readings are notoriously inaccurate. The best way to check voltage is with an accurate voltmeter.

even if im getting the current values in hwmonitor?, I haven't put the card in yet.. because those voltages to me look a little scary.. but its been running for 3 hours now no issues

Run something to stress the system and see if they come up to normal values. But I have had very poor voltage readings in software that turned out fine when I checked with my Fluke. Personally, I wouldn't give it another thought. But if you are the nervous type, borrow or buy a voltmeter and check at the 24 pin connector:

(take measurements to ground)

ok, another question then, I just checked the bios and its looking good on voltages?, so can it just be software reading it wrong or something like that?, I know the powersupply isn't that great and I already tore out the stock.. I just got this pc today for 150, for a i3 2120.. figured id put a powersupply that I had laying around in it till I get to upgrading it more lol

The Windows based software should get its voltage readings directly from BIOS. But, it doesn't surprise me that HWMonitor is wrong. It is wrong on my Phenom II/MSI 785 MB also. Besides, if you have Speestep enabled in BIOS to lower the freq/speed of the processor when idle, the voltages will follow.

alrighty, ill test and see how it runs with the graphics card here in a few, the powersupply I put in is a lot better than stock (liteon), and the amps where higher than the stocks.. so I guess its just reading wrong

PS: I can tell quite a bit of speed difference between this little i3 2120 and my old q6600 dell xps 410

I have HWmonitor running on my other machine. It is showing the +12V at 5.016, the +5V at 3.447. The vCore at 1.464 when I have it set at 4.75 in BIOS. So much for HWM accuracy.
