Marketing Information The USB to RS232 converter allows you to connect eight non-USB RS232 DB9 devices to your USB bus. The USB Hubs are ideal for connecting factory automation devices, such as data loggers and industrial machinery, or any device that depends on links that aren't affected by excessive noise or spikes in voltage.

Why install an internal serial adapter to get extra COM ports when using an external USB connection makes more sense? This USB Hub converts your serial RS-232 devices to USB-adaptable peripherals without sacrificing serial connection speeds.

The hub features high-speed UARTs with 128-byte FIFO transmit buffers and 384-byte FIFO receive buffers. It connects easily to peripheral serial devices in an external plug-and-play fashion. Because it's hot-swappable, you can install it without having to power down your PC.

The hub comes with all necessary drivers, utilities, and help files for quick setup in Windows 98, Windows Me, Windows 2000, and Windows XP operating systems. Simply load the included software drivers, then connect the hub to your USB port and an RS-232 serial device.

GOLD-CERTIFIED QUIET POWER

CORSAIR RM Series Fully Modular Ultra-Low Noise Power Supplies with multiple EPS12V connectors deliver consistent 80 PLUS Gold efficient power to your PC and have all the connections needed to power today's most demanding PC upgrades.

AVAILABLE IN BLACK OR WHITE

Going for a stealthy look or modern minimalism? RM Series PSUs are available in black or white variants to fit your build style.

TUNED FOR LOW NOISE OPERATION

A 140mm rifle bearing fan with a specially calculated fan curve ensures that fan noise is kept to a minimum, even at full load.

HIGH EFFICIENCY

With upwards of 90% peak efficiency, RM produces less noise and less heat, which means less time worrying and more time gaming.

FULLY MODULAR WITH MULTIPLE EPS12V CONNECTORS

Completely modular cables means you only connect the cables your system needs, and the wide range of included cables adds broad compatibility with modern graphics cards and motherboards.

Also compatible with the CORSAIR 12-pin GPU power cable for the hottest new GPUs.

ZERO RPM FAN MODE

At low and medium loads the cooling fan switches off entirely for near-silent operation. Once the action picks up, the fan activates, ensuring critical component temps stay in check.

TECHNOLOGY AND RELIABILITY

For consistent, reliable power and superb electrical performance, each RM Series power supply features a robust resonant LLC topology with DC-DC conversion and 105°C rated industrial-grade capacitors. With precise timings, RMx supports Microsoft Modern Standby, ensuring extremely fast wake-from-sleep times and better low-load efficiency.

CERTIFICATIONS

The Cybenetics organization measures efficiency and noise levels across the PSU's entire operational range, using more than 1,450 different load combinations.

The "Gold" efficiency rating is defined as ?87% to <91% (depending on input voltage).

The "A-" noise level test is measured in those same configurations to be ?25 dBA & <30 dBA under noise data averaging.

TEN-YEAR WARRANTY

CORSAIR provides a ten-year warranty on all RM Series power supplies; your guarantee of reliable operation that will last across several system builds. If you need help, CORSAIR customer service and tech support are always on hand.

YOUR BUILD, YOUR WAY

Every fully modular CORSAIR PSU is compatible with a wide range of CORSAIR accessories. From individually sleeved cables in a variety of color combinations to 12-pin micro-fit GPU cables and 12VO motherboard cables, complete your build your way.
