Is a 500w enough for Gigabyte GTX 970 G1?

I'm looking to get a new graphics card and I'm wondering if a Gigabyte GTX 970 G1 will work on my psu. I have a Corsair CX 500M power supply. I've seen people say get at least 600w and others say it will run fine with a 430w as long as you don't overclock. Gigabyte's website says to have a 550w psu. I'm not sure if it will work and I don't really want to get a new psu.

Thanks

SPECS:
CPU: AMD FX 6300 3.5ghz
COOLER: Cooler Master Hyper 212 Evo
MOBO: MSI 970A-G43
RAM: G.Skill Ripjaws 8gb
STORAGE: WD 1tb
GPU: MSI Radeon HD 7850 2gb
PSU: Corsair CX500M
CASE: CM HAF 912

 

Yes.

Based on those specs, wattage wise, it should be fine as long as your PSU isn't too old... though you wont have a TON of headroom.  The 970 also looks like it needs 28 amps on the 12v rail, and your PSU is capable of 38 amps.  So you should be good there as well.

So, yeah.  Should be fine, but I'd still recommend upgrading that PSU when you are able.  Just to be safe, and to give yourself some room to grow.

Yes but you might be bottle necked just a tad with a 6300 and a 970, not sure though maybe not

I'm in a similar situation, wanted to see if I could ask here without creating a new topic. My psu is the Zalman 500HP, it seems to be a very high quality power supply, http://m.newegg.com/Product/index?itemnumber=N82E16817379005
Would this be enough for a 4.6ghz 4690k with 1 hdd and 1 ssd?

you should be fine. I doubt the 970 will use much more power than your old 7850
