Do I need a new PSU?

[NirK]

I have an Antec Earthwatts EA650 that I bought after reading the review on "johnnyguru" (back in 2010, so the discontinued Earthwatts series) I sent the original purchase back due to buzzing and got a replacement 2 years ago. So the PSU is physically 2 years old and was released in 2008.

My question is do you think a need a new power supply to run modern hardware such as a AMD radeon 280x, GTX780 / 970? How much have PSU's developed in terms of reliability and components inside them in the last 6 years? Or are they basically the same as they were 6 years ago?

Is my Earthwatts EA650 which is less than 2 years old going to be alright or would it be safer to upgrade my PSU when I get new hardware? I notice a very quiet buzzing from it sometimes I am not sure if this is normal.

Also if the PSU dies what is the probability of it taking out other components? I have never had any problems with this other than slight buzzing but if I am spending £700 on new components I want to be sure it will be ok and will not damage them!

Be fine unless you run 2 heavy drawing gpu's.

Buzzing is probably slight coil whine, technically it's not a fault in the context of performing it's power supplying job. It's common if it's quiet, most PSUs will product some audible electrical vibration noise at some point.

At worst it's can be very annoying.

If your not overloading the PSU it will be fine.
