i have a custom built computer, and was looking to upgrade my graphics card to a amd r9 280x. i am looking at getting the sapphire amd r9 280x toxic edition, and it says the recommended power supply is a 750w. i went on newegg and did a power supply calculater with a 7970 in the calculations, and it said it would consume 590w with my computer. i have a corsair cx600 power supply, and was wondering if that would be enough?

Best solution

It would be enough because the newegg calc always overestimates. 600 is the general recommendation http://www.realhardtechx.com/index_archivos/Page362.htm

You'll need a minimum 500watt for an R9 280X... and your's sufficient!

Did it work? I just installed the card (r9 280x) and at around 2 hrs of use, the power supply blew up, it was a 600watts power supply. The tecnician told me that it burned because the power supply was insufficient for my card and processor (fx 8350)

i am having the same problem, my gpu keeps giving me very strange textures on my games and even on my desktop.... but when i lower the graphics it reduces this problem, is it possible that the psu is to weak for the r9 280x, my psu as 550watts

Well, it COULD be your PSU (power supply unit) since i dont know the rest of your specs. You may have received a bad/broken card which can show artifacts (weird lines and textures). You could try support and or RMA the card if it still has coverage... If all else fails, just get another PSU! Good Luck!

Okay i'm going to post the obvious answer to this question.
MORE POWER IS BETTER
The recommended GPU minimum power supply is a recommendation only (as in BARE MINIMUM REQUIRE TO RUN THE GPU ONLY NOT YOUR WHOLE SYSTEM)

When you are building a system you need to take in to account the requirements of everything, such as Motherboard power Requirements, CPU, GPU, RAM, HDD/SDD, Peripherals, PCI devices such as LAN and Sound cards.

For a typical system with 1x R9 280x, i7 4770k (newest overclockable CPU to date of post (average out about 150watts+ for a CPU if you want to stable overclock it)), HDD, Network Card, DVD R+RW, Mouse, Keyboard and Cooling system i'd say around 750 - 850 watts minimum is required and don't be scared to spend a lot of a PSU, skimping out on a PSU can mean 2 things - system goes boom or PSU goes boom either way loosing you money. But this also gives you 10 - 20% extra leeway encase you decide to overclock or keep the same PSU for a few years.

You are wrong! The recommended PSU size is for the total system and is always high because there are so many low quality PSU's out there that are overrated. A quality power supply with a high amount of amps on the +12 volt rail is what is needed even if the total watts are less than recommended!
Here is proof where you can see actual measured total system load http://www.anandtech.com/show/7601/sapphire-radeon-r9-2...

It would depend on the quality of it. A good quality one would do it but a generic one would not.

i run Fx8350 , asus sabertooth 990fx , 16 gig corsair dominator , 1 tb velociraptor hdd , coolermaster watercooled 240 mm radiator , and 2x R9 280 graphics and is running well on a corsair CX 750 psu
it seems stable enough in gaming , but dont know for how long
they told me that 1 card in my system would need 500 watts and 2 cards 1000 watts , the logic of that baffles me as yes , 500 with 1 card but only need to add the power from the second card not the full system again

I'm crossfiring R9 280x with another and I've got 750W PSU and it's not enough -_-
