First, you want to . to end a sentance. Not ! Otherwise your post was easy to read and no worse than most things I read here.

450W doesn't tell us very much. Your parts don't need a lot of electricity but not all 450W PSUs are the same. While it might say 450W on the side, it could be a lot less. From what I gathered though it seems more like a temp issue. Because you start off ok and then it gets worse over time. You said "normal temps" but that doesn't tell us if it's safe temps or not. Try to make sure your CPU is 65C or less and your GPU is ~80C or less. And try to find a good PSU.

It's all good with the temps I ve changed thermal paste two months ago.... Gpu Max temp it's 75 degrees and processor 60 - 63.... I've benchmarked every thing and all are good temps..... A benchmark tool who can relieve me the temps can you give me?

All good with the cpu. I'm gonna benchmark gpu with heaven to to see temps. I will come with update.

I've benchmarked gpu 81 degrees on extreme profile. It's all Good.... Pc doesn't restarts with these temps. While gaming cpu and gpu its not used full on extreme. All temps are good. I don't thing it's the temps.... It's psu I think or my house have problems with 220 w on my howse electrical network... What you suggest? Buy a new psu will help me?

Don't. Bump. Posts. Edit with any more info you want to add. Final warning.

I have no clue if your house wiring is good. You'll have to have an electrician look into that. Poor PSU is an option. Have you checked the event viewer? Did it happen while testing?

PC doesn't restarts when benchmark but I found a critical errors after restarts and says like this : "The system has rebooted without cleanly shutting down down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly".

How many forums did you post this on?

LOL!

Your DELUX! PSU is garbage. As I stated elsewhere. It's not a true 450W PSU. It's old and cheap. Replace it.
I don't have the money to invest in pc like you think. In my country it's very expensively . I want to make sure if it is the PSU or something else.

I find it slightly odd it handled testing ok without reboot. My guess is if it's a power issue you weren't testing the entire system, so the draw was low enough. I agree with the above. Even if it's not the PSU that PSU can cause issues later.
