Hello, i downloaded this app called HWInfo, because i wanted to see if i really had problems with my power supply, because my computer was restarting randomly without posting anything on the screen. I did a 10 minute test without putting my computer on load, here i have a screenshot: http://prntscr.com/mvw6eq
If you guys want to help me and make a right choice, i don't want to spend money, thanks.

Ok. Check the voltages in BIOS. Alternatively, if your mobo manufacterer has a Windows app for monitoring and/or overclocking then it will likely show the voltages and they should be more accurate. This is because the manufacturer knows which sensors relate to each of the measurable voltages from the PSU and third party/freeware apps don’t always interpret this data correctly (same for temp sensors, too). See the tolerance table in the Wiki after checking voltages in BIOS and if outside these ranges then your PSU is out of spec (or the sensor(s) are wonky):

All your PSU voltages are skewing towards the low side, but the most reliable source for voltage info is in BIOS. Usually it’s a page called PC Health or Monitoring or something like that. The only downside is the PC is not under stress in BIOS, but then again if they are low while in BIOS then there’s something wrong with the PSU anyway. The hwinfo pic shows these voltages while your pc is idle?

Yes, these voltages are when the pc is at idle, only the browser is open (Chrome)
