PCI-E 4X expansion to four USB 3.0 ports

The myVolts PCE4CE-A41 adapter plugs into a single PCI-E x4 slot and presents four USB 3.0 connectors for additional peripherals. It targets builders who have run out of native USB headers or need extra ports for mining risers and data-intensive accessories. The card uses the ASM1806 controller and draws power directly from the slot, so no auxiliary cable is required.

Gold-plated USB ports and direct slot power

Four gold-plated USB 3.0 interfaces reduce contact resistance and help maintain signal integrity across all ports. Because the board is powered entirely through the PCI-E connector, the motherboard supply remains isolated from external adapters, improving stability during sustained transfers. The plug-in design also eliminates ribbon cables, shortening the signal path and cutting potential points of failure.

Installs in x4, x8 or x16 slots without cables

The card fits any PCI-E x4, x8 or x16 slot but will not function in an x1 slot. Driver support covers Windows XP, 7, 8, 10, DOS and Linux, so most systems recognise the device without extra software. Builders must verify that their motherboard provides a compatible x4-or-wider slot; systems limited to x1 connectors cannot use this adapter.

Questions about this item

Will the ASM1806 chip or the four USB 3.0 ports need periodic replacement under normal use?

The ASM1806 controller and gold-plated USB 3.0 ports are solid-state components with no moving parts, so they do not require scheduled replacement.

What throughput limit appears first when all four USB 3.0 ports run sustained transfers through the PCI-E x4 link?

The PCI-E x4 bus and ASM1806 chipset set the aggregate bandwidth ceiling, so combined traffic across the four ports cannot exceed that link's capacity.

How much extra heat or power draw should I expect when the card drives four USB 3.0 devices continuously?

The card draws power directly from the PCI-E slot without an external cable, adding only the load of the ASM1806 controller and attached USB devices to the motherboard supply.
