Will a cpu with a higher TDP work if upgrading from a slightly lower TDP?

No, as long as your PSU can power the entire rig (including the GPU and other components) and at overclock power.

There is no such CPU as the i5-5790k, if you are talking about the i7-4790k then you will have no problem, any board that can handle a 4460 can handle that. Now as to whether you can overclock it, thats a different story and depends on the board.
I'm honestly unsure what my PSU capabilities are. When I first did it my question I said that I was upgrading two a 5790k, that was a typo I meant to say that I was upgrading to a i5 4690k and my main concern was whether or not using a higher TDP CPU would have an adverse effect on the systems temperature and overall performance. Sorry about the confusion guys...

If your PSU is capable of running the i5-4460, there is a high chance that it will run a +4W TDP increase on an i5-4690K. Now, if you are overclocking, that's a different story. OC'ing, depending on your voltage increase, will bump up power consumption to +30W over TDP (even more).
It will be best if you tell us what your PSU is (brand/model).

That system was available with a 4790 so you're definitely fine. With a 350w PSU which is likely not high end, I would NOT overclock, however its unlikely that that board could even overclock if you wanted to.

If I'm not mistaken that Asus M32ad has a PSU made by AcBel, the HBA008-ZA1GT 350W. It is sold as "350W" but the actual total continuous power is only at 286.4W, while the combined +12V rail (at 13A per rail x 2 rails) max. load power is only at 216W. https://www.amazon.com/ASUS-HBA008-ZA1GT-350-Power-Supply/dp/B01429U3XI
This is an indication of a poor-quality PSU. Although this particular PSU being able to deliver 216W at the +12V rail *may* provide enough power for your new setup, but on certain conditions of power consumptions of your PC, it *will not* be sufficient.
Your GTX 1060 3GB would consume a calculated power of about 135W (this was based on anandtech review of the MSI Gaming X 3GB). http://www.guru3d.com/articles-pages/msi-geforce-gtx-1060-gaming-x-3gb-review,7.html
Your new i5-4690K can consume a power load of 77W when not OC'd and up to 92W when OC'd (this was based on hexus review of the cpu) http://hexus.net/tech/reviews/cpu/71265-intel-core-i5-4690k-devils-canyon-22nm-haswell/?page=8
A typical system load test (with a different GPU) shows the i5-4690K (with all other components) consuming a total of 109W on stock speed and up to 180W when OC'd to 4.8GHz (this was based on bittech review) https://www.bit-tech.net/hardware/2014/07/03/intel-core-i5-4690k-review/6 Note that their test setup was using the Nvidia GTX 680 2GB (a more power-hungry card than the GTX 1060) BUT the system load test was done by stressing the CPU (as this was the component being reviewed) and not the GPU.
Theoretically, the CPU + GPU combined power draw would be around 77W + 135W = 212W when not OC'd and 92W + 135W = 227W when OC'd.
If both CPU and GPU are reaching 100% load and consuming max. power. The total would definitely increase more than the 212W non-OC'd and 227W OC'd values.
So, with your PSU only capable of providing 216W at +12V, you will be pushing a low-quality PSU to its limits and even beyond.
My suggestion is to replace that PSU of yours with a higher quality model with ample wattage. A 450W to 500W PSU should be more than enough for your rig (making sure enough wattage are being provided at the +12V rails).
