Up to 377 LEDs is the ASH-S1 total to plan around

Every addressable device in a build draws from one shared number, and getting that number wrong is the easiest way to overrun a lighting plan on the ASH-S1. Up to 377 LEDs is the figure printed against this hub, and it applies once, across everything connected, not per port.

Quick Answer

Up to 377 LEDs is the ASH-S1's total lighting capacity, applying across everything plugged into its nine 5V addressable ports combined, not to each port individually. At R349, the hub also carries nine separate PWM fan ports and a remote, though the product page is hidden until stock is confirmed with no date set yet.

➕ One number, not nine

The single easiest mistake to make with this figure is assuming each of the nine addressable ports gets its own share of 377 LEDs. It does not - the rating covers the hub's addressable output as a whole, so every fan ring, strip and cable cover connected across all nine ports draws from the same 377-LED budget. A build with three fans carrying sixteen LEDs each and a strip carrying forty is already sitting at eighty-eight, well before any of the remaining six ports are touched.

🧮 Working out where a build actually sits

Getting an accurate total means adding, not estimating. Most addressable products state their LED count in the description - a small fan ring is often in the sixteen to twenty-four range, while a longer strip or a lit cable cover can run into the eighties or higher. Add every connected device's count together rather than eyeballing the total, since lighting adds up faster across a full case than it looks from any single component.

🚫 What exceeding the rating means

The 377 figure is a stated capacity, not a soft suggestion, so pushing past it sits outside what the product is designed to run and risks inconsistent behaviour on the lighting side. If a planned build's total comes out close to or above that number, the options are trimming a device from the plan, moving one device to a motherboard header instead, or splitting the lighting across a second hub. Individual LED counts are worth checking against Evetech's case fan range before adding devices to the plan, and where a build's lighting needs sit close to the ceiling, the NZXT fan controller is a sensible alternative to look at.

Frequently Asked Questions

Is the figure per port or in total?

In total. AsiaHorse's own listing caps the addressable bank at 377 LEDs combined, not per device.

How do I work out my own total?

Add the LED count of every connected device, including fan rings, strips and cable covers, into one figure.

What counts towards the 377 limit?

Every addressable LED the hub is driving, regardless of which of the nine ports the device is plugged into.

What happens if a build goes beyond the rating?

It is a stated capacity, so exceeding it is outside what the product describes and risks inconsistent behaviour.

Do all lighting products publish an LED count?

Many do, though some do not, which is a reason to leave headroom rather than planning right to the limit.

Does the fan-port count relate to the LED total?

Not directly. Nine ports is a connection limit while 377 LEDs is a capacity limit, and either can bind first.
