What are your other requirements?

• Is this for a production or a one of a kind hobby/repair project?
• How budget aware are you?
• you mention portability. How often would you need to unplug it? And will it be done by you or someone who requires a bit more user proofing?

Have you considered using more than one pin per pole? Ie if you had a 15pin connector, that can take 3A per pin, then shorting 3pins will give you 5 pins 9A. There will be more considerations to this though. Like how can you make sure that the parallel pins present a similar resistance, so you don't get an unbalanced load.

Anderson powerpoles. They're like Lego, non-gendered, and will handle your current requirements. I use them to make harnesses in my scientific equipment applications all the time under specs similar to yours.

10A is a pretty big ask. You might want a few more pins to spread that current around. What are you other pins used for. DE-9 is where I would probably start.

There's automotive plugs which use more or less standard spade connectors which you can wire yourself and they can easily achieve 10A and things like relay sockets can manage 40A or more. JAE is one of the brands manufacturing all kinds of connectors, with and without panel connectors, but there's a ton of manufacturers around. I suppose on marine stuff you can find connectors like that too.

But if it's for a LED strip and you don't need to constantly move them around, I'd suggest using a dirt cheap spade connectors with color coding (reverse male/female connectors on the live one so it's physically impossible to connect led strip in reverse polarity). Or even cheaper, use screw terminals and be extra careful when wiring the strip in.

And for the dupont-style connector commonly seen on LED strips, 10A feels like quite optimistic value. Obviously a LED strip can pull 10A and many times that, but quickly googled ballpark estimation for 2,5m 10A led strip calls for 2,5mm² wiring all the way trough and your cheap flexible LED PCB from amazon/ebay is pretty far from that. But that depends heavily on what you actually have and if you've measured 6A then it's pretty reasonable to have the rest of the setup to manage 10A.

I'm a big fan of Amphenol mil-spec connectors. They're a bit expensive, but not terribly so. You could almost certainly find one that meets your requirements.

How about a 6 pin connector?

Cable side connector with strain relief. https://www.digikey.com/en/products/detail/amphenol-industrial-operations/PT06SE-10-6P-SR/341057

Bulkhead connector. https://www.digikey.com/en/products/detail/amphenol-industrial-operations/PT02SE-10-6S/341071

To include or exclude the strain relief, add or remove the "(SR)" from the part number.

PCIE 8-pin connectors supports up to 150W (12V/12.5A), but they're meant for internal use, not chassis.

If you want to get 120W, chassis-mounted, your best bet is usb-c.

10 amps is a crazy ask. Are you trying to power the entire device with this port? If so, consider common ports (what's wrong with IEC C14?).

You could try these: https://www.amazon.com/PIN-PANEL-MOUNT-MICROPHONE-CONNECTOR/dp/B00H57AJEI/ref=mp_s_a_1_6?sr=8-6

https://www.amazon.com/5-PIN-CB-MICROPHONE-PLUG/dp/B00H573MO2/ref=mp_s_a_1_1?sr=8-1

Both of these match up nicely and are rather beefy though they don't actually say the current rating.

There's also these that are rated for 300V 15A https://www.amazon.com/5-08mm-Terminal-Connector-Pluggable-Connector-Phoenix/dp/B0CM3Y1WS5/ref=mp_s_a_1_1?sr=8-1

Dang 10A is kind of beefy, what is this for?

Do you need IP rating?

If you didn't need 10A I would have recommended M12 connectors
