Is Seasonic 520W 80+ Bronze enough?

[420Dopamine]

Is my Seasonic 520W 80+ Bronze PSU powerful enough for running a system with GTX 970 and i5-4690k (will probably OC a little bit).

GTX 970, Gaming stress: 170w
i5-4690k, fully stressed: 88w (might get to 110 @4.5GHz)
Other components: ~50w (Exaggeratedly)

The total system draw, maxed out both the CPU and GPU, and hooking up 10 cellphones charging, will be like ~300w. So yes, that's enough.

It's not Haswell compatible so you may have to disable the sleep states in the BIOS.

I wouldn't OC with it.

Overclocking in gaming is useless. Anyway, you can overclock it for other purposes, and it'll be OK. This PSU will not hold you back completely, just don't try to get to 4.5 GHz. Try 4.2GHz, above this point the stress on the PSU gets higher, and you could end up regretting it.
