First time asking a question so be gentle. I got my gf's kid a r9 280x for Christmas and I've had to rma it 3 times so far. It still has artifacts and gets really hot >100c. I've tried it in multiple computers. It actually killed a year old ocz 600w gold psu. I measured it with kill a watt at 457 Watts with an i5 3570k oc'd to 4ghz both full load. So there is no reason I can see why I'm having issues. Asus has not contacted me at all about it they just send the card back worse each time.first time it was sticky and smelled like ramen. One time it was sent back in a mother board box with no bubble wrap. After all the bs the card WILL work in my i7 4930k build with a 1kw gold corsair psu. That makes me think it IS a psu issue. Thanks in advance guys.
 
Download and run HWINFO - Sensors on the gf kid pc. Post the results.

Maybe its power supply, maybe mobo. Maybe someone has just fiddled with the settings - raised the crap out of its voltage. Are you using Afterburner to overclock and check settings on the card?

All power supply measurements are within .13v except 3.3v is reading 3.46 (I checked with a multimeter when I first had issues) which is still ok and doesn't apply to gpu as far as I know. I wont be able to check hwinfo until later, maybe tomorrow. The card is not oc'd at all i got the fastest memory (6400) and core (1070 i believe) available at the time i bought it in october. i used msi afterburner at first to monitor temps with defaults but since it got hot i used ccc and it was still getting hot. as far as i know voltage wasn't even unlocked in afterburner. Thanks for the help so far.

I got back the card again, still had the same issues but I figured them out. Firstly the artifacts and bsods were because the psu only has 30a on +12v rail and the min for the card is 42a so a new psu fixed that. I got a rosewill 660w with enough current. The temps are still an issues but I read its because Asus didn't design the heat sink so it touches the Gpu ram in order to dissipate the heat properly and bc the ram is running at 6ghz it gets hot I guess I'll have to put a copper shim between the ram and the hs. Thanks for your help though, I actually stumbled onto the info while browsing the net one day. It makes sense though now that it worked in my 2011 PC since its rated for 84a on the 12v which is plenty.
