Connecting 12V LEDs with 0.72W & 1.2W Ratings to 105W Power Supply: Usage & ZS800 Compatibility

I have a total of 2 simple questions.
I have 12v leds after connecting;
5x 0.72w and 5x 1.2w which is 9.6w
I have a power supply for leds with 105w help. The power supply will be disconnected from the 230V side
Will such a power supply use 9.6 watts (+ some for your needs) or much more?
I also have a power supply (zs800) 12v, like 800mA, which gives 9.6W, but it seems to me that it may not cope.
Here is also the question of how to calculate if it can do it?

Of course, it will take from the mains as much as its load plus losses in the power supply. So you load the power supply with LEDs with a power of 9.6 W, the power supply will take 9.6 plus a few watts for losses in the power supply itself.

In this topic:

Someone says that 800 mA is a momentary load for 12 V. This power supply can continuously deliver only 600 mA - so it cannot cope with these LEDs in the long run.

Then use a 105W power supply or buy a power supply with a continuous current greater than or equal to 800mA / 12V.
