Let's See my luck and what will happen?

what will happen if u connect ur pc load to ac regulator 500 VA=400 watt, while ur whole pc must have 1600 va=1000 watt what will happen?

i did this without my known about this technical stuff my psu stop working but it still give power to motherboard and case fans
but wonot boot for me any more , my psu is Corsiar HX 850 WATT , my psu now at workshop for fixing i hope only psu damaged
my rig was :
Core i7 4770k
EVGA gtx 780ti SC W/acx
Veangence 16 GB 1600mhz
PSU Corsair HX 850 WATT
Samsung 256 GB SSD Pro series
1 TB WD black caviar 64mb cash memory
Z87 GD45 Gaming motherboard from MSI
i hope my pc is fine while psu comes with board in its circuit that shuts off pc in over voltage over current etc ..... what do u think people happened to my pc

Your PSU was not able to draw the correct amount of voltage and amps it needs to function at it's rated level. Most likely it damaged the PSU circuitry but not the components in your system , they were just underpowered and unable to function.

inzone is correct. However, Do the power supply fans still spin up, or are they dead too? Your PS was designed to run on specific input voltages (110/115v or 220/240v) and amperages only. Anything more and it will overheat and shut down or fry the electronics inside. Your PS has over voltage and under voltage and over current/temperature protection measures built in that shut it down to prevent damaging the rest of the PC components if it gets over loaded, so the rest of the parts are more than likely fine.

Something inside the PS is damaged and it's not supplying the correct voltage to the CPU and other peripherals. Fans don't use much power at all. CPU's and GPU's do. A new PS will more than likely fix your issue.
