Will the 18-gauge wire for the ATX 8-pin connector suffice for a 24V, 18.8A, 450W load?

I discovered a 16 gauge male 8 pin connector, but a female version isn't available unless I create it or find something else. I managed to locate the male cable only. I might have to craft my own, but saving time would make me prefer buying one.
I located a 16 gauge male 8 pin connector. What are the specifications of your PSU and are you using another PSU's cable kit or harness? Regarding the wire gauge, they typically range from 16AWG to 18AWG, but be cautious as not all PSUs have identical pinouts, so you shouldn't transfer another PUS's harness onto a different modular PSU. I could create my own cable, but it would save time. The main question is why you need this particular cable. If your PSU doesn’t have the required connectors for your project, you either have the wrong PSU or the incorrect components.
I'm using a HDPLEX HIFI DC-ATX 500 watt unit.
It comes with a custom 8-pin barrel cable.
It operates on 12-48v.
I removed the modular ports and soldered my own wires.
I plan to install a 16 gauge 8-pin connector myself.
This barrel cable isn't suitable for higher power inputs above 330 watts.
That is the cable I'm checking to see if it can handle 24 volts and 18.8 amps.
When examining the insulated part of the wire with markings, it measures 18AWG, but you were advised to use 16AWG instead. You plan to create a custom cable length with the correct connector. Connectors and terminals are available from MDPC-X; you can find more details here: https://www.cable-sleeving.com/crimp-ter...connectors. I'm wondering why you require such high power input from the power brick, and what stops you from using an ATX PSU? If you remove the barrel connector, what would be the expected input for the PSU? It seems like you're not overcomplicating this, as modders like Joshua Sniffen at NFC-Systems use the same PSU in their builds without altering the power brick or the barrel connector, assuming it's a PC setup.
Thanks for your response. I discovered a 16 gauge cable but only the male version was available, and I couldn't locate the female one. In the end, I managed to obtain the 16 gauge female cable. Now I have all the necessary male and female cables in 16 gauge. I plan to install 16 gauge cables. You're correct that I could have chosen a lower voltage and current and used the original barrel cable instead. However, I'm unsure about the exact power requirements. I might only need around 400 watts or less. A representative from HDPLEX told me that power supplies operate more efficiently at higher voltages, specifically between 24v to 48v, so I decided to go with the higher voltage option. They didn't mention the maximum current per voltage, but I was advised to stay below 40 amps, likely referring to 12 volts. I've discussed this with everyone here and assumed a maximum of 500 watts or 550 watts based on their advice. The website should provide the maximum amperage the power supply can handle as input. My planned running voltages and amperage are 27v at 18.50 amps for 499.5 watts, and 24v at 18.8 amps for 451 watts. I probably chose the 24v option because it seems safer without knowing the exact power supply limit. I own a MEAN WELL LOP-500-27 AC-DC and a MEAN WELL SE-450-24. The second one is simpler, cheaper, and more common.
