Very Confused Need Ideas, Very low fps After Watercooling

To start my system specs are:
Motherboard ASUS Z170a
CPU intel core i7 6700k running at stock 4.0ghz with 4.2 boost
GPU Evga Gtx 1070 SC Gaming Black Edition
RAM 2 x 8 sticks of HyperX Fury 2100 16gigs Total
PSU Corsair 450watt (i think cx)
1 512gb samsung ssd
1 1tb WB blue HHD

Recently I decided to Water cool both my GPU and CPU with the EK a240 G kit. Its a custom water cooling loop that EK sells. I am very confident that it was installed correctly and had no leaks. After the install I tried to play battlegrounds and was getting very low frames like 20-30. Thinking it was just the recent update and would get better with the next, I moved to Overwatch and again got very low FPS, 30-40.

After looking at temps and different graphs on the GPU and CPU together and running some CPU and GPU benchmarks, I've found that whenever my CPU needs more resources my fps drops. When running unigine valley on ultra it was pushing upwards of 180fps, but when I started to run Prime95 at the same time the frames in Valley dropped to 30. Benchmarking my system with Passmark I noticed that my cpu was a little low but I think that it is enough to be causing my issue. (8000 ish compared to 11,000)

Initially I thought the extra fans and pump pushed my PSU over the limit, but after borrowing a second psu to hook the pump and fans too the low fps persisted. I have also reseated the Gpu, Cpu (with new thermal paste), and ram (one stick at a time in different slots) Also reinstalled the nvidia drivers, with no luck.

I'm really lost here and don't know where to start to fix this issue. I would like to avoid buying lots of parts and returning what doesn't fix it but I understand that might be the option. Right now i'm thinking it could still be the psu, or my motherboard isn't supplying enough power or the lanes to the gpu are fried. Really hoping its not the cpu....

Any Ideas would be Greatly appreciated, as I don't like having a $1800 paper weight laying around.

EDIT: I updated my Motherboard Bios and still got low FPS. Both CPU and GPU were hovering around 60-70 percent.

Mobo updates are easy. Just go to your board manufacturers page and type in your boards model # and it should take you to the drivers page for what version of windows you have. Just look at the ones available and check to see if they are newer than your current ones! If possible, check the resource usage when possible to see if there are any conflicts there

It was just a oem dell 300w that I only had the pump and fans running off of. my 450 was still powering my system. Basically removed the new components off of the psu to take it back to how it was on air. Also good to note that I had a AIO cooling the cpu before the custom loop.

From what I guessed, even without your custom loop your system was pulling ~410w just with the hardware it had. Even with the 300w supporting the loop, youre still pretty near the limit of your PSU. I'd consider getting at least a 800w for what you have to have adequate headroom. Another thing to think of would be updates. I would suggest GPU updates, your BIOS to the most recent version (if it isnt already) and then any package updates. One last thing; if you look at your resource usages while playing games, is anything at or near 100% usage?

Okay ill try the PSU first. And I have reinstalled the most recent gpu updated as well as rolled back a couple to see if something odd was happening with the newer one. Ill try the mobo updates and see if that helps, I haven't dealt with Mobo updates yet, are they more difficult or pretty straight forward? Ive also wondered if the Vrm's on my motherboard would be the problem, Since when my CPU draws more power my GPU suffers.

As for hardware hitting 100% I'm not positive on Cpu but the Gpu was around 60-70 and i think the cpu was jumping up to 100 but not staying there.

I've also noticed that youtube and other webpages stutter, lose fps, when i move my mouse. Idk if this helps at all

Awesome. Ill give these a try but probably wont get to test resources again till tomorrow night. Thanks a lot for the input.
also I added above that I lose frames on youtube when i move the mouse. so I don't know if that is anything that helps.
