The 564W available at the +12V rail on that PSU should be more than enough for that combo.

The CM Thunder is an old budget PSU with no reviews to speak of. It's quality is really questionable when it released. All in all is a really low quality model.

Since the PSU is pretty old and was released in 2012(before Haswell), it most likely is a group regulated unit. For newer CPUs(4th gen or newer) that's a bad thing, because of the added sleep states C6/C7 in which the power draw is significantly lower than previous gen CPUs. That's a problem for a group regulated PSU(+12V and +5V are regulated together) ... voltage for the +5V will go out of the ATX spec usually at really low loads on the +12V, which is the case when the CPU enters those low power draw states(your 9600k). Also, at really high loads on the +12V and really low loads on the +5V, voltage will again go out of spec... nowadays the main power hungry components will use the +12V rail while the +5V is used for the storage devices logic and on some components of the motherboard(USB for example)... you'll be in this case quite often.
Because the +12V and +5V are regulated together, these group regulated units won't ever do well in crossload tests(that's when one of the 2 rails is put under a high load and the other is under a really low load)... it gets worse on a low quality PSU like the one you have currently.

I'll recommend going ahead and upgrading your current PSU to a newer DC-DC unit.
A great quality 550W model will be sufficient for your build, these models are great: Corsair RM or TXM, Seasonic Focus Plus, Superflower Leadex III. It's never a good ideea to cheap out on a PSU because it can take your other expensive components with it when it fails.
