What is ESTONE Self-Powered Technology?
ESTONE Self-Powered Technology is a new solution to add more power supply on USB 3.0 expansion cards. The old version PCI Express USB 3.0 cards need to plug power cables from Desktop PC's power supply unit. Even added on additional power, sometime it still lacks power when running few high power-consuming devices simultaneously such as USB HDD/SSD enclosures and USB NVME enclosures. PCI Express slot can provide 75W max power almost 12V/6.25A for PCIE devices. ESTONE add 4X voltage transformer on USB 3.0 card will pick up 12V/3.5A power and convert to 5V/8A 40W. Each USB 3.0 port will get 5V/2A 10W max power supply for USB 3.0 devices. Most of the high-power consumption devices just need 4 - 8W which means this USB 3.0 expansion card can light up 4X high power-consumption devices simultaneously.
Product Advantage:
- 1. 4X added-on USB-A USB 3.0 ports with 5Gbps total bandwidth USB expansion card will not occupy Motherboard USB 3.0 Main Lane Speed, it is added-on bandwidth by PCIE X1 Main Lane.
- 2. Bluilt in ESTONE Self-Powered Technology, no need to plug any power cable from Desktop PC's power supply unit. Provide sufficient power (5V/8A max) supply for USB 3.0 devies. Light up 4X high power-consuming USB-A devices simultaneously.
- 3. PCI Express bus connection, ensure fast and stable using experience lost few transfers' speeds. Never have lost connection issue like external USB HUB does.
- 4. Fully support USB 3.0 (USB 3.1 GEN1, USB 3.2 GEN1) standard 5Gbps max speed, will backward compatible with USB 2.0 480Mbps speed and USB 1.1 12Mbps speed.
- 5. PCIE X1 interface design, will works on PCIE X1, X2, X4, X8, X16 slot. X2 slot, do not work on PCI slot. Based on PCIE 2.0 standard, will compatible with PCIE 1.X, 2.X, 3.X, 4.X PCIE slot.
