Wired a the red and black cables from a 'chopped' usb cable directly into the ATX motherboard connector (purple and black connections) and found that I could successfully charge/power my USB device even though the computer was 'off'.<br />

Hi,<br />
<br />
I have a USB device which I want to keep powered when the computer is turned off (not standby or hibernate but off) - but still plugged into the mains. i.e. the PSU is still 'live' but the fans are not running and I beleive only standby power (VSB) at 5V is supplied to the purple wire on the ATX power connector to the motherboard.<br />
<br />
Can I wire the red and black wires from a USB cable directly into the power connector (to purple 5v VSB and black wire ground) and expected my USB device to receive 5v power to keep it running ? <br />
<br />
Is it dependant on the powerdraw of the device ?<br />
<br />
I haven't put a meter on the ATX purple wire yet but would appreciate some feed back if what I'm thinking of is feasable.<br />
<br />
Thanks.

Using VSB 5v Power To Keep USB Device Alive When Computer Is Off ?

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

Components

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.

A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e., the memory and microprocessor). These auxiliary devices are intended to be connected to the computer and used in conjunction with it. Examples of external peripherals include mouse, keyboard, printer, monitor, external Zip drive or scanner, while internal peripherals include CD-ROM drive, CD-R drive or internal modem. Today's new devices, such as tablets, smartphones and wearable computing devices are considered peripherals as they can be connected and used on a computer system. The difference, however, is that these devices can run independently of the computer system.
