Need some advice about my PSU.

[Metarch]

I'm soon going to put a watercooling loop together and I'm not quite sure about how to work the pump into my PSU setup.

I'm using an Antec HCG 620M PSU, which has these ports...

And I'm going to fit an XSPC D5 pump for the loop, which uses this plug;

I'm fairly new to all this, so I'm not entirely sure what the procedure is as far as installing aftermarket gear is. My question is, will that pump plug work if I plug it into one of the HDD ports on my PSU?

You'll have your 4 pin peripheral (aka Molex) connector from the PSU plugged into the pump and you'll want to plug the single blue (tachometer) wire into the motherboard's CPU_FAN header. That'll allow you to monitor the pump speed and provide a warning in case of pump failure (the computer will tell you CPU fan failure but you'll know it's a pump failure).
One thing to be aware of with that set up, when starting from a cold boot you may experience a CPU failure warning that isn't accurate, it's just that the fan (pump) has not reached the speed the CPU expects it to be at within it's millisecond timeframe. Watch the temps in BIOS to verify the CPU is remaining cool if you do get that warning (but only when first starting the computer), restarts should not cause that error message at all (unless the pump actually fails)

Right, I understand the basic procedure better, and I do thank you for running that by me, but what I meant with my question was, is there any problem with running that 4 pin Molex connector from the HDD port specifically? Like, is it built so it will only allow hard drives, or will it work with the pump just fine?

It appears that the cables listed HDD from the PSU are SATA power only, I would try to refrain from using those (you'd need an adapter anyway) for the pump

So how would I go about powering the pump?

The molex connectors should be on the cable from the PCI-E/HDD
