Hello, I'm looking to buy an AIO liquid cooler for an older PC.

My PC has
Gateway FX6840 Motherboard H57-AM2
GTX 1050Ti
12GB DDR3
1TB HDD
128GB SSD
750W PSU
In a Cullinan MX Rosewill Case

The cooler I'm looking at is here

What I'm worried about is it uses a 3 pin connector that powers the fan. Led's, and the pump. I was told to make sure I have a header on my mobo that is capable of a 1A draw. Its a little confusing with understanding pwm and amp output on my motherboard connections and Im just concerned that when I receive this I will either have nowhere to plug it into my mobo, or the spot I do have to plug it in is not capable of powering this unit.

Thanks for any help
