20 years ago seems pretty recent to me, but some devices (as electric heaters) can introduce a lot of problems. You should use a dedicated high amperage circuit for such devices to avoid overloading your wiring.
 
But, if you don't want to do that, a simple UPS of any brand will most certainly solve your problems. APC is fine

Thread moved to Cases and PSUs.
 
And I would agree with @LoGiCalDrm, seems like your electrical circuits need to be checked!

Or you could get electrician to check that all sockets are fine.

You won't get more fps because of a SSD,only load times will improove

Youll gain no fps from upgrading storage, just faster load times. If it's for gaming, upgrade CPU first, then storage. 

I would upgrade the CPU first. It is more expensive, but far more worth it.

CPU for sure

Get the 6600k

Sry, you missunderstood. English is not my first language.
I mean with "pls read the manual",  need to look further at the manual for examples
i did these screenshots from the manual and there are some examples for m2 configuration.#
  Sry for my bad english
 
 
>You r welcome 

Msi use "TWIN TURBO m.2 64Gb/s" in their z170 boards. Each of m.2 ports can use 32Gb/s. It will not be a problem.

But m.2_2 Port is a little bit slower than m2.1 Port because of the Switches between itsself and SAta ports.

m.2_1

m.2_2

 
 

HI, your m.2 slots use the Lanes from PCH. Z170 Chipset has 20 LANES!!
Here from your mobo

 
If you use both m.2 @pcie mode, it will disable sata express port and sata 5 and 6 port and use the lanes from them
 
Here is the Table 

 
Both m.2 SSDs can run @x4. Together 8 Lanes...
m.2_1 Port has 4 lanes alone. M2_2 port shares 4 lanes with satae and sata 5 and 6 ports..
 
Your GPU will stay @x16
Pls read the manual... 

Awsome, thank you again for all the information. Im guessing you looked the manual up online? I used the manual that came with the board its self. I should have looked it up online thought too. Thanks
