Question Do two different video cards consume the same power on the same settings in games?

Hello, I have just bought a new gpu, a Rx 580 8gb nitro+, before I had a gtx 960 4gb.

I have an issue, whenever I try to play games even on the same settings as I did with my old card, the pc restarts. I think the issue might be with my psu, as it is and old one and "only" 550W.

I have tested it with OCCT, CPU works fine, but when I start the CPU and GPU test it immediately restarts the pc. But to be sure that the problem is with my psu, I'd be interested in that the two cards consume the same power on the same game settings.

Intel Core i5-7500 3.4GHz
Rx 580 nitro+ special edition
16GB DDR4 2100MHz

Your old card required only a single 6 pin pcie power connector.
Your new card needs a 8 pin connector in addition to the 6 pin.
That increases your psu requirement by some 150W.

What is the make/model of your psu?
Does your psu have both a 6 and an 8 pin connector?
If not, you need a better psu.
Do not try to use an adapter, particularly with a older psu that might not be delivering power on the 12v rails where modern parts require it.

If your psu is of cheap quality you open yourself to damage to all of your parts if the psu should fail under load.

I cannot give you the exact model of the psu, all I know it's make, Kraun. It is a really old psu, maybe even 8 years old.
 
If this is the data plate of your psu, it is totally inadequate.
The combined 12v rails total only 190w max.
I have no idea how they can claim it is a 500w psu.
Pick a tier 1/2, no worse than 3 psu from a quality list like this:

Thank you!

That's gotta be a new low from what I've seen. "500W" that can only supply 190W on the 12V rails. Heck, even if you add up ALL the rails, you only get 296W!!!

If that's indeed the unit you have, definitely get a new PSU
Also, I'd cut all the wires off so nobody can ever use that thing again.
