Definitely not. CX is a poor PSU to start with and 280X needs a lot of juice.

Try this:

PCPartPicker part list / Price breakdown by merchant / Benchmarks

Power Supply: EVGA SuperNOVA 750W 80+ Gold Certified Fully-Modular ATX Power Supply ($94.99 @ NCIX US)
Total: $94.99
(Prices include shipping, taxes, and discounts when available.)

Ya :(  thats what i thought. I really don't want to fry my computer though. That would just be the worst cause this thing is my only gaming/everything device since i sold my 360. Guess my gpu upgrade is going to have to wait for awhile until i can muster up the cash. Plus overclocking is something i definitely want to do so I'm going to need some head room. Plus it would be nice to get a new monitor along with a new gpu. Guess the 7770 is gonna have to do for now. Thank you for saving my computer from eminent destruction!

280X only consumes 250w full load. So you're probably getting atleast 400w on full load with your system. I have seen some people who use that psu with no problems, though I think they use 600w.

"NewEgg also states that it's rated for 12V@38A (456W), but the label on my unit clearly says 12V@34A (408W). I don't consider 48 watts on the 12V rail to be merely a minor discrepancy."

Quote from one of the reviewers. Get a GTX 760 or R9 270X instead.

I would really like a new graphics card now. Do you think the r9 270x would run (being overclocked like my cpu) on my 500w power supply

Yes, just don't take the Sapphire R9 270X Toxic and you'll be fine. that consumes a lot of power.

okay I need some more help and would be very grateful to anyone could answer this. I have searched the web for information regarding this many times and can't come up with a definitive answer. DOES A r9 270x 4gb version use more wattage and power than the regular r9 270x 2gb version? If so how much? I know the maximum wattage for the regular version is about 180w.

Negligible amount of more wattage.

You don't need a 4GB for R9 270X. 2GB is enough as I think you are only using one monitor.

Thanks! Now you said the Sapphire toxic edition consumes a lot of power. It is a 4gb model. What makes it so that it consumes so much more power? Also won't 4gb make a difference in Skyrim or Fallout with really high detail texture packs? Or when using anti-aliasing?

It's a factory overclocked card so it runs on higher voltages and consumes more power.

I'm going to go with the 2gb version cause it doesn't make a difference I guess. Okay last question before I buy the card. (( http://www.amazon.com/Sapphire-Version-PCI-Express-Grap... )) Can I overclock this safely with my cheap little cx 500w psu?

Take it easy don't push it too far. CX generally has a weak 12v rail. Upgrade it ASAP.

Will do! thank you so much for the advice that simple web searches won't give. I am going to get a nice psu to build on for my next computer build that i plan on doing once Fallout 4 is announced. ( fingers crossed for within the next year) Im planning on getting a nice psu ASAP that is at least 750w. Like the one I think you recommended.
