I have an 80+ power supply made by cooler master with 500 watts. Is it enough power to drive a non-overclocked system with an i5 4460? I'm running a gtx 760 right now. What if I'd get a new i7 instead of the i5?

so the questions and facts in one list:
I have a power supply with 500 watts (80+) and an I5 4460 which I think of upgrading later.

My question was if I needed a ps with a larger wattage to drive the radeon r9 390 and the i7 in the future.

Thanks in advance,
kind regards Max

Possible, though I would recommend a better power supply as suggest above.

you'd use approximately 350W when gaming, and worst-case would be close to 400W total system. Other peripherals and the amount of GPU overclocking can affect this as well so you might go over 85% load at times which I wouldn't recommend.

The i7 will add further power drain.

If you bought the GTX970 then it would be a different story. Your PSU is fine for that.

Other:
With an i5-4460 + GTX760 I'd personally wait for one of the upcoming AMD Polaris or NVidia Pascal GPU's.

AMD Polaris should be several months sooner (though actual delivery is unknown). Current power estimates put Polaris at roughly HALF the total power thus assume 150W instead of 300W which...

Cooler Master sells a lot of poor quality power supplies, and some high quality ones. Your PSU will be insufficient and too low quality to power the 300W R9 390 (since I cannot recall any 80 plus Cooler Master being high quality). With a $330 GPU, you want to get a higher quality power supply.

II would grab a quality power supply like so:

What si your exact PSU though? It'd be nice to know.

a) i7-4790K (stock 4.4GHz max turbo) approx 109W
b) + 150W GPU
c) add 41W for fans etc
d) TOTAL (worst-case) approx 300W (or 67% load on 500W PSU)

Thank you so much for your answer. I guess I'll wait then for the next gen AMD gpu and hope it will cost around the same as the 390. When do the AMD gpu's usually get released?
