RX 580 keep shutting down the system on intens load

[Alvin_25]

so my RX 580 nitro+ 4GB keep shutting down after heavy load on the graphic card, for example when i run CS:GO after 5-10 minutes it will shut down the system BUT if it can run for more then 10 minutes when ever i try to close the program the system shut down again. same thing as furmark.

and it only happen the past 2 days usually it run alright. before it happens i playing around with trixx i overclocked my GPU and only crash once after crash i set it to normal again and the next day this happen.

i already re-install the driver with DDU and install the latest driver, no help.

is it cause by my power supply? and how do i to fix it?

specs:
i5 4460
sapphire RX 580 niro+ 4GB
Enermax naxn 500w
8 GB of ram
wins 7 64 bit

Did you have another card before this one?

Did you have another card before this one?

yes and it was a very old card AMD HD 5500 and it run on this system for over a year until i upgrade my GPU

Could be a power issue , that PSU isn't the greatest.

so i have to upgrade the power supply? can u suggest what should i get? the best and cheapest one i really don't understand about powersupply and i think i don't have money to buy a new powersupply for right now, can i somehow lower the clock and still be alright until i can buy new powersupply?

PSU is my guess since the other card had a lower power draw.

Did the PSU solve the issue?

No it's not i bought new PSU and it still shuting down the system, it's turn out that the VGA to HDMI adapter that i use to conect my old monitor is the problem, when i test it with my HDMI TV everything works fine
