Is this PSU good for my build

[SantoDel]

I recently bought a cyberpower pc and forgot to change the standard PSU. So, I was looking at PSUs to replace the standard one and found the CORSAIR TX Series TX850M 850W 80+ Gold Modular Power Supply. Is this good for my build?

It's much larger than you need. The TX550 will work, TX650 if you want to OC.
