Let me begin.

First of all, here are my specs:
-CPU: Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz
-GPU: NVIDIA GeForce GTX 750 Ti (2GB)
-Motherboard: Asus Maximus Hero VII
-Memory: 8GB RAM (4x 2GB)
-SSD: KINGSTON SV300S37A240G (250GB)
-HDD: ST31000524AS (1TB)
-Operating System: Microsoft Windows 7 Ultimate Edition Service Pack 1 (build 7601), 64-bit
-Monitor: Eizo Nanao L985EX (Maximum resolution 1600x1200)
-PSU: Floston FL500 500W

I think we can call it a good gaming rig. But I've got a huge problem, the performance is not even close to the expected for the PC specs.

For example 3D Mark Score: http://www.3dmark.com/3dm/11735647?

Also all the processor's cores are unparked, optimised windows for gaming, etc...

Lately for some reason in task manager the cpu utilization goes up to like 60+% for lame things. Also I am into YouTube and with OBS with the lowest possible decent settings any game goes terribly bad. So that's the reason why I use ShadowPlay for the least amount of gameplay affect. But I would really like to use OBS...

Do you think it might be the PSU's fault or RAM or what?
I'm currently trying to fix my PC for a very long time and can't understand the bad performance for the good specs it has

PLZ HELP! :D

Why are you running an expensive rig with a power supply that is most likely extremely dangerous? You don't know the dangers of a power supply like that, one that won't even show up on a Google search. Now, PSUs don't affect performance, but can damage hardware or cause freezes and shutdowns. Well, I take that back, if it has sucky ripple it can cause overheating and throttling of other components.

Also, your PC is not that high end because of the GPU. It's so unbalanced. 4790K with a 750Ti :no:

Are temps good across the board? Stress test passes? Drivers up to date? I have seen more unbalanced components run together, but turkey has a point, 4770k should have a bit better pair of eyes than a 750ti. And I am sure it's a good idea to invest in a better PSU.

PSUs can ABSOLUTELY affect performance. You can't get good performance from a GPU card that is struggling just to run, at varying levels of "just trying to run", when it has to deal with noise or ripple or fluctuating voltage. Absolutely affects performance. It's not JUST about hardware failure or incremental damage. Nor is is just about the fact that that PSU is in the extremely probable category when it comes to it's potential for letting out magic smoke from your hardware or itself.

I found that PSU, and its specs are horrible. Honestly I think that is the worst PSU I have seen, in a very long time.

It doesn't even have proper amperage, for a 750ti, let alone anything better. https://forum-en.msi.com/faq/article/printer/power-requirements-for-graphics-cards

That score seems normal for that GPU. If you look at the comparison to similar systems you see that you are right in the bell curve of performance. A highend CPU isn't going to make a world of difference for a GPU based benchmark.

You'll have to be a bit more specific about what kinds of "lame" things are using the CPU so heavily. Just because they are not interactive does not mean that they are not complicated tasks that require heavy CPU usage. You may have a virus or just a bad setting in your OS "optimization"

I have used various cheap and nasty power supplies in the past.
I never had any reduction in speed or performance, but the cheap PSU all failed and had to be replaced, which is a PITA.

Agree with grimfox, a fast processor won't make a mediocre GPU any better.

Sometimes background tasks like windows update consumes a lot of CPU power. Don't worry about it.

Who cares about benchmarks anyway. Are there any games or applications which your PC does not run acceptably?

The OP will have to respond with his temperatures of his hardware. Use MSI Afterburner also to check your clock rates of the GPU and CPU. If the PSU has horrible ripple, it may not so much throttle the chip itself but the VRM which can downclock the hardware, so all that is necessary to know.

Yeah his PSU for sure may be one of the worst.

Yes, a power supply will only cause low FPS, for instance, if it is literally throttling hardware. If you take a PSU with 60mv of ripple on the 12V rail compared to one with 10mv of ripple on the 12V rail, the hardware will perform exactly the same speed, assuming temperatures of the VRM and chips are intact, and no throttling is occurring. Now, take a PSU with 140mv of ripple, that could indeed cause the VRMs to throttle, yes.

PSUs with lower ripple will overclock better, so they can provide potential for better performance. But in terms of equally clocked hardware that is not throttling at all, yes you won't notice any difference in speeds.

If you draw more power from the rail than it can handle, or the GPU card becomes starved for power because the power supply simply cannot supply it consistently, the whole system will see potential for instability, and not from throttling. Throttling is an entirely different issue. Instability across the board can occur with a low quality PSU. Ripple, noise and poor regulation all affect the VRMs, CPU and memory function when the problem is substantial enough.

As to the graphics adapter itself, if the load it is under requires a particular power draw, and that cannot be provided, then it will certainly either crash, exhibit artifacting, demonstrate instability or simply burn up the power supply on units without adequate protections.

Option 1 - do nothing.
You didn't mention your PC crashing or overheating, your Cinebench score is about right for your GPU.
Your PC is probably working Ok

Option 2 - upgrade your PC. You said it is a pretty good gaming rig, but actually it is not so good.
The 4770 CPU is MORE than you need for gaming, but the 750Ti GPU is LESS than you need for newer games. A GTX 970 would be more than twice as fast as your current GPU. Even a GTX 950 would be a big improvement. If you do upgrade, replace the power supply at the same time. EVGA supernova or seasonic are very good PSU. 600W should be plenty

Well, if your computer is 3 years old, then the power supply has lasted well, and so must be a lot better than Turkeyscratch or Darkbreeze think it is.
BUT, When you added the GPU, you increased the load on your power supply, which won't help it at all.
Power supplies lose capacity as they get older, and so replacing it soon really is a good idea.

As for gaming, You must have noticed a big improvement when you went from integrated graphics to a 750Ti.
But most people building a new gaming PC with an i7 processor would be trying to decide between a GTX 970 or a GTX 980!!

The PSU only lasted this long, due to the fact that the IGP isn't very hungry with regards to amperage, compared to a dedicated GPU. That PSU has beefed up 3v and 5v amperage, with a weak 12v amperage, that is needed for a dedicated graphics card. More often than not, 12v amperage > Wattage of the unit.

I wouldn't be so sure about that. For one thing, power supplies don't really "lose capacity", as the energy comes from your wall socket and a power supply basically just converts that energy. The components are still the same components as when they were new - I don't see how that could decrease the maximum power, if there is such a thing in the first place. Power supplies can be overdrawn and have protections kick in or burn up long before the internals' power restrictions would ever remotely come into play.

So, no offense, but HA HA HA HA HAAAAAAAAAAAAAAAAAAAAA. Really? Heh.

If you knew how many people use cheap off brand or OEM units for years, and instantly have an issue or a catastrophe the minute they stick a discrete graphics card into the system, you'd know exactly why I can only laugh about that statement.

Yep, that'd make ripple less stable, so in sense the PSU does have less capability to fulfill hardware requirements while keeping voltages intact.
