Which PSU for this build?

[goldenzero]

Hey, I'm upgrading my computer, but I'm not sure which PSU to use.

The build:

CPU: Intel i5 4690K

CPU cooler : Cooler Master Hyper 212 EVO

Mobo: MSI Z97 PC Mate ATX

RAM: Kingston HyperX Fury 8GB (2 x 4GB)

Storage: Samsung 850 EVO 500GB SSD and Seagate Barracuda 500GB 7200rpm HDD

GPU: EVGA GeForce GTX 980 4GB FTW ACX 2.0

Case fans: Two 120mm case stock fans

Optical drive: ASUS DRW 24B1ST DVD/CD-ROM

I also plan on using at least two USB 2.0 ports at one time, and overclocking my GPU to 3.7-3.9 GHz and maybe more somewhere down the line.

PSU: ??

I have my old Corsair HX 620W PSU and I would love to continue using it. However if that is not possible, I would love some suggestions on cheap alternatives.

Thank you.

As long as your Corsair unit is in good order you can use it. It has enough power for the job. You might try to blow the dust out of it and make sure the fan spins ok.
