Amd R9 290 power consumption

[muhtaseemjabbar]

I was reading up plenty of reviews of the new AMD R9 290 and I was very surprised to see the board power consumption being 250-300W. Am I not considering a detail here or is it really possible to have that powerful gpu running in my system with my 500W power adapter? I mean, my radeon hd 7870 requires a 500W power supply and that one is significantly less powerful than the R9 290. Is there a difference between board power and overall power consumption in that case? Also, is there a correlation between gpu power and board power consumption or overall power consumption (if they are different things)?

Here you have total system power consumption http://anandtech.com/show/7481/the-amd-radeon-r9-290-review/15 it does not exceed 400watts.

yes board power is just for the GPU, overall is the whole system cpu/gpu/motherboard/hdd

yes, the overall power consumption takes into account your CPU (anywhere between 60W or so to 120W), as well as the motherboard, various harddrives, other add-on boards, and fans.

in an odd attempt to make people's lives easier, manufacturers suggest PSUs for the overall power consumption, typically assuming the GPU's own power consumption, or board power, to be around half of that value.

So do you guys think that if I were to hypothetically buy the R9 290 my current 500W power adapter would be able to handle it considering it does fine with my weaker AMD radeon hd 7870 and also considering I keep the rest of my rig the same (i5-2400 processor and 12 gb ram, 2 500GB regular Hitachi drives)?

THEORETICALLY yes it should be fine. in practice it'll depend on the age and brand/build-quality of your power supply.

although your power-supply is rated to be able to push out 500W, it's ability to do so deteriorates with age and use. additionally, many of the cheaper power-supplies actually fail to put out the rated wattage under real world conditions (around 50 C inside a computer case).

If your current PSU is high quality.

Thanks man. I didn't know that about psus in general and that solved my question.
