I have a gtx 1060 3gb and i experience stuttering in games especially when loading new areas or cutscenes, should I upgrade? Most games are almost unplayable. Here is my psu https://ibb.co/j6drHk.

No, a PSU is not something which will cause stuttering.

Have you ever put too many things on one electrical outlet? It overloads and trips a circuit breaker. It does not only deliver a certain amount of power and no more. It gets overloaded. The circuit breaker then acts as a safety mechanism to prevent overheating of the wires and a...
A PSU won't cause stuttering. If it is overloaded it will overheat and shutdown. A crappy one will overheat, blow out, take the computer with it and possibly cause a fire.

Stuttering is usually because the CPU is not fast enough. Perhaps you don't have enough RAM.

I can't find a review for the SC-500A. From what I can gather from the label it's not the worst PSU I've seen. It correctly tells you how much the different rails can be loaded to. A 360W on the 12V rail 500W total PSU tells me it's a group regulated PSU. It's not the greatest PSU ever, but from what little I can gather I don't think it's a total fire hazard either.

I agree with Velocity. A weak PSU isn't something likely to cause stuttering unless things are running at a lower clock speed because they can't get enough power. You said "stuttering in games especially when loading new areas or cutscenes", which to me means drive issues. I'm guessing you either have little ram, or are using a slow spinning harddrive. If you are using a "green" drive (meaning a less then 7200RPM drive) or have a small amount of ram then that's the issue. Full system specs would be very helpful.

I have installed msi afterburner and I noticed that my gpu is never at 100% and drops in frames corespond pond with drops in percentage, does that mean the problem is psu related?
 


No, a PSU is not something which will cause stuttering.

Have you ever put too many things on one electrical outlet? It overloads and trips a circuit breaker. It does not only deliver a certain amount of power and no more. It gets overloaded. The circuit breaker then acts as a safety mechanism to prevent overheating of the wires and a fire. It does so by cutting all power to the circuit.

The same sort of thing happens with a PSU. A good quality PSU will detect it is overheating. It will instantly cut all power it can't limit the power. All power is cut and the computer turns off. Some even have a fuse.

A very poor quality, non-UL certified PSU has no safety mechanism. It will continue to overheat from too much current draw. This will likely result in catastrophic failure. If you are lucky just the PSU dies, if you are unlucky it takes the computer down with it, if you are really unlucky your house burns down.

Hypothetically you could put 1000w worth of components on a 300w PSU. It may even run for a few seconds before it blows out or the safety mechanism cuts all power.

If your video card never hits 100% and you see stuttering. Then look at CPU. Don't just look at full CPU usage either. Look at usage per core. If one core is peaking at 100% while gaming. The CPU is limiting the game. Multiple cores are of no help if a game is not multi-threaded or not multi-threaded well. As one core peaking can limit everything else.

There has been no mention yet as to what CPU you are using, at what clock rate and which games are giving you trouble.

Also have you looked at your video cards memory usage? 3GB is not much nowadays. If you are very near or over 3GB usage due to your settings. Performance will be crushed. It won't matter if you aren't hitting 100% GPU usage. If you go over the video cards VRAM capacity. Data cannot be fed quickly enough to the GPU to hit 100% GPU usage.
