Upgrading GPU concerns

IR0NxLEGEND · Aug 2, 2014

I want to upgrade from a Radeon HD 6850 to a SAPPHIRE Radeon R9 280X. I am concerned about my low power supply with the stronger card.

There is my complete and current set up. is my 500 Watt sufficient with the new card? I don't plan on doing any overclocking and using only for gaming. Thanks

That PSU is not very good quality. I would replace it with an XFX, Seasonic, or Antec unit. 550-650w is plenty.

i have that cpu and power supply but the 600w version and that should do the job for that graphics card yes

This guide says you need 600w.

It is not the wattage that is important, but the 12v amps. The CX500 can deliver only 38a.

Depending on which R9-280X you pick, there are a large number of unfavorable reviews on newegg.
I might look at a GTX770 or GTX760 which takes less power.

OP has a cx500, not a cx600.

Post corrected, thanks.

Try a Seasonic or Evga 650 watt PSU. They are high quality and quite cheap!

Can you please explain to me the whole 12v amps only delivering 38a? I see that in the corsair specs, but where do I look for the requirements with the card?
