This is one of the reasons a lot of people advise against getting a CX series PSU unfortunately
It could be coil whine. It definitely isn't normal though. I would highly suggest RMAing it before it does any damage to the rest of your PC. Is the noise constant or only when drawing a decent amount of power from it?

Post your build so we know how many Watts you need.i5-4690K

The G2 750 is perfect for you
it may be more watts than you need, but it leaves some headroom and since it won't be pushing the limits of the PSU it will stay nice and silent. -

I am looking to ideally spent around $90, as that is what I paid for my CX750, and is what I had budgeted. I don't really plan on running SLI ever, so should I just drop down to 650W and save some there?

AMD R9-290 - On your average system the card requires you to have a 550~600 Watt power supply unit.
AMD R9-290 Crossfire - On your average system the cards require you to have a 800 Watt power supply unit at a minimum.
If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina.
If the board is CF capable, I'd get an 850 watter.... if sure you will never ever go there, a 650 watter is more than enuff
$95 XFX Core Edition

Yes, you could go down to 650W and I'd recommend an XFX or Seasonic PSU for that wattage. It is good to spend a decent amount on the PSU though as obviously you don't want to buy another cheap PSU that will give you problems like the CX series already has. But yeah Seasonic and XFX both make good quality 650W power supplies
Although it's slightly more expensive than what you wanted to pay, the G2 750W has the best ripple suppression and voltage regulation out right now so you definitely wouldn't regret it. If you are considering a 750W XFX you my as well go for the G2.

These will suffice. You will still have overclocking room.

I will probably go ahead and get the 650 or 750W XFX Core edition. Everyone concur?650 for single card
850 if you want freedom to upgrade to CF in future for a 75% increase in performance at little cost
Both have way more than enough juice for serious overclocks. 750 has no real return for the additional expense

Also, does it matter than the crackling generally happens when the system is under load? For example while running prime95 or burntest, the whine becomes unbearable. Could that indicate that it is something other than the PSU? Or no?Probably not. If you are sure the noise is coming from the PSU it sounds like you got a dodgy one and something on the inside of it is struggling to keep up with the demands of your PC. By the way, thank you for selecting one of my answers as the best, I've spent a while trying to help out and I appreciate it
Best of luck with your new PSU after you order it! -
