New build isn't so stable

[Father_]

For the passed couple months I've been buying parts for this new build and I've finally put it all together, but for some reason games are not running as smooth as they should (which defeats the purpose of this build :/ ). While I'm running BF4 on any setting I get very frequent FPS drops from 60-50 to 7-4 or it just freezes up. To add to that I've got this annoying rubber banding, although I could play the game perfectly on my old build. I have no clue what the issue could be, nothing is overclocked and everything is at stock. The games I play were running stable more or less on my older build, but I made this one to be future proof and so that I could play all my games on Ultra. What could the problem be and how can I fix it?

New Build:
i5 4690k (Stock)
Hyper 212 Evo w/ 2 fans (new)
Gigabyte GA-Z97X-Gaming 7
Kingston HyperX Blu 8Gb @ 1333Mhz
Sapphire R9 280 Dual-X 3Gb GDDR5 384Bit
SolidGear SDGR-750E 750W PSU

Old Build:
FX-8320 @ 4.2Ghz
Hyper 212 Plus w/ 2 fans
Gigabyte GA-990FXA-UD3
Corsair Vengence 8GB @ 1600Mhz
EVGA GTX 660 2GB GDDR5 192Bit
CoolMax ZW-600 600W PSU

It might be your power supply. It's from a brand I never heard of and it's not 80 Plus anything.

It could also be the AMD GPU.

If you are talking about banding as in on the monitor then that is coming from your video card. just swap the video card back to the 660 and I bet it will fix it.

But my build isn't using anywhere near 750W or even 500W

It felt like a network sort of rubber band. BF4 was the only one with this issue.

I bet that power supply can't push 650-750 watts at or above 50 degrees celcius and those AMD GPU's run hot and use a lot of watts relative to the performance they give.

Is there a program that I could use to make sure the PSU is the problem?

Well you can put in another PSU and see if the problems persist. Maybe the spare 600 Watt CoolMax you have.

Ran fine and I could even keep a stable overclock. Lucky for me it hasn't been 30 days just yet 😀 Thanks.
