Power Consumption Radeon R9 280X

Hey guys I just wanted to ask if the R9 280X ( XFX Double Dissipation model) really needs a 750 Watt PSU as mentioned on their website?

I currently have a Corsair CX500 watt PSU. Is it enough or will I need to upgrade my PSU as well?

A Radeon R9-280X needs 30 amps on the 12v + rail and a 550 watt power supply with 1 - 6 pin PCIE and 1 - 8 pin PCIE power connections.

So does my PSU cut it or do I have to get a new one ?

I would upgrade to a better power supply , the CX SERIES from Corsair uses poor capacitors.

It would run the card , but may fail sooner than later.

So if I would go for something like a GTX 970 which needs a minimum of 500 watts would be fine ? Also If I were to upgrade my PSU which specific model would you recommend ?

GTX 970 PLUS THIS.

Sorry to bother you again but what about the R9 285? Does it consume less power? It says 190 Watt TDP instead of the 250W TDP of the 280X

Get the 970.

without switching power supplies ?

I would get the 970 and the XFX 550.
