Hi there and welcome
Those are some nice components But it would be a shame to spoil it with a low grade power supply. Make no mistakes, the power supply should be considered a key part of a system and not an afterthought. A bad one will cause many problems.
I have not heard of Tecnimax PSU's. Nor can I find any reviews of them on reputable sites. This alone is enough to make me wary of them. They also claim right on their site in their specifications an efficiency rating at maximum load of 72%. In these days of 80 Plus being standard, and high end PSU's achieving much better than the base 80 Plus requirements, this is not good. What this means is that at maximum load (700w claimed), it will be drawing nearly 1000w from the socket. All the excess is wasted energy which is emitted as heat.
I would look to a decent PSU like say:
http://pcpartpicker.com/part/xfx-power-supply-p1750snlb9 - High quality 80+ Gold PSU made for XFX by Seasonic.
http://pcpartpicker.com/part/rosewill-power-supply-capstone750 - 80+ Gold PSU made for Rosewill by Superflower. It's a high quality unit also.
http://pcpartpicker.com/part/corsair-power-supply-hx750 - 80+ Gold PSU made for Corsair by CWT.
http://pcpartpicker.com/part/corsair-power-supply-cx750m - 80+ Bronze base level Corsair model. Pretty good, not quite as good as the above, but sometimes can be found cheap with special offers etc.
For a case, you don't have to spend a lot but I wouldn't go too cheap either. I like the Corsair 200R as it has good cable management features, excellent ventilation and looks decent but is well priced.
Also some suggestions in general:
The Intel i5-4690K (Haswell Refresh "Devils Canyon") has just been released, at a similar price to the i5-4670K. It is said to have improvements to make it more overclockable, but also has a slightly higher base clock speed.
If you do go with the i5-4690K then get the Asus Z97-A motherboard instead which is based on the new Z97 chipset.
If you are overclocking, then the Arctic Freezer 7 is not the best. It is better than the stock cooler, but if you want to overclock then a Cooler Master 212 Evo or similar will be a better choice.
