Can my psu handle a GTX 970?

[gumzepi]

So I'm building my first pc and I was initially planning on getting a GTX 960 but apparently thats not gonna come til 2015. So now I'm thinking of just going ahead and spending a little more for a gtx 970 since i don't want to wait too much longer but my problem is the psu I already bought is a cx600m and I'm worried that it wont be able to handle the gtx 970. I've read about other people experiencing "coil whining" sounds coming from their gtx 970's because  their psu's weren't good enough.

Basically what I'm wondering is if it would be safe for me to just go ahead and pick up a 970 considering my psu?

In case it's important the other parts I have right now is a gigabyte ga990fxa ud3 motherboard, fx 8320 cpu, 2x4 gb g.skill ripjaws 1600 ram, and just a plain old hard drive I took from my old pc.

it can handle 3 of them

Its will be perfectly fine.  It will probably even be able to handle 2-3 of them

 

Coil Whine normally occurs because the PSU was made somewhat poorly.

a cx600m will be more than fine for a 970

thats not true. a cx500m will handle one. a cx600m would handle 2.

thats not true. a cx500m will handle one. a cx600m would handle 2.

di you watch linuses video quad sli gtx 980's overclocked with a 5930k only drew 540w from the wall and the 970's are more efficient

A cx500m will probably be able to handle 1 gtx 970 and any processor overclocked no problem. Cx600 could probably handle 2, but I wouldn't overclock that much, just in case.
