550W for 290X

[Eurofighter]

My brother has an intel i7 4770 with a Seasonic 550W PSU G series and a AMD 7970 graphics card, the 7970 has just broken. He wants to replace it with a 290x. Just checking if the PSU Will have enough power?

Also which AMD 290x would you recommend for not much more than £300?

Thanks.

483w. Close but looks like it will be enough.

also remember that as a PSU ages the maximum output also tends to fall a bit. Best thing is to give it a go. if your system shuts down or reboots then you know you need a new one.

It may be fine in the interim, but I would look to replacing it with a solid 650w+ unit in the near future

That or convince him to replace it with a GTX970, that will certainly be fine on a 550w.

It will not be fine, I had my system pulling ~630w from the wall when running 3Dmark when I had my overclocked 290.

How were you using that many watts with a 290? That must have been some crazy volts being pushed through the processor and gpu.

I am running an i7 4770K and a 290X quite comfortably with an OCZ 600W power supply.

Even with processor and 290X overclocked the most I have seen being used is about 450W and that includes monitor and speakers.

With the 4770K and 290X at stock the power used is about 350W at load.

It will be fine.

Depends if he's overclocking, though saying that i've had my little 500w pull way past 650w from the wall on a single 290 and about the same on a 780ti. @stock and normal gaming, pssh...will be fine.

I'm pulling just around 450W in gaming load with a 290 PCS+ and a 4670k overclocked.

600W Corsair CX600, so not a "high quality"-unit, but it's enough.

That 450W is from the wall with a cheapo meter, so in reality the system is using like 400W.

The max ive seen my pc use is 360w thats a 4790k with a xfx dd 290 overclocked
