R9 280X with a Corsair CX600 psu: problem?

I recently purchased a "slightly used" r9 280x graphics card on Ebay. Things worked the first time I booted with it, but the Heaven benchmark crashed a few minutes in when I was testing, and when I restarted after that, windows was a black screen with a mouse appearing occasionally.
I contacted the seller about the problem and was told I needed at least a 750w power supply, that a lower wattage (like my Corsair cx600) could cause the problems I was having. My question is, would the cx600 really be so insufficient as to cause these issues with a perfectly functional r9 280x? Should I upgrade power supplies, or return the card?

In theory a CX 600W should handle it. CX isn't an ideal PSU for gaming rigs though. A lot of times CX won't even make 12v on the 12v rail and cause all kinds of havoc for GPUs.

I'm more concerned with this being an Ebay card. Miners are dumping cheap cards on Ebay and elsewhere, and a lot of these cards were pushed at high overclock 24/7.

Regardless, the card should still be under warranty. See if you can RMA it.

Wow i have that exact same PSU! i didnt think about it being non gaming when i got it,it was just as a replacement for a dead 500W psu,Your card should work alright! this also depends on the ammount of HDDs and Disk readers you have running!,check a Psu requirment calculator and try getting some watt above so it is not a close cut!.

the ever so slightly used GPUS on ebay that come from miners are usually Cheap because a miner spend a load of money on mining rig that didnt get them anywhere !,or that they killed there card so hard that they try earn some of that bodied card money back on amazon!/ebay!,Check if the receipt is present,Email the creator of the card to see if they can ID the card using the info you were given! if you are under warranty and your details check out with the creator go for it!,but dont expect too much!

Thanks for the advice. In that case, I'm returning the card and maybe the PSU as well.
Do you have any recommendations for a power supply for my fx-8350/R9 280X rig, then? I'd like something reliable that will last a while, but I'm not looking to spend over $100. Ideally around $50-60 but maybe that's too good to be true?
