Windows 7: USB power question

USB power question

I have two PCs in my office: self-built mATX tower & HP TouchSmart IQ506. I also recently bought a WD My Passport Essential SE 1TB portable hd.

Yesterday I plugged the new drive into the self-built pc. It didn't work. Tried the ports in the front of the case and those on the back.

Then, out of curiosity, I tried the drive the TouchSmart. It worked normally.

What is the problem with my self-built pc not putting out sufficient power for the drive? The specs of the pc are below.

I have had this happen before with older portable hard drives, an inland sata/ide usb drive adapter and a 2.5" ide drive enclosure. All these devices except the usb drive adapter are powered from the pc. The adapter has an ac plug.

It is a psu problem, a mobo problem, both or what?

links of my devices are below:

Have you tried other USB devices in the ports?

If you suspect PSU, I suggest taking the PSU from the Touchsmart and putting it in the other machine.

1. Problem lies with my custom-build tower NOT with TouchSmart

2. TouchSmart is AiO so I am reluctant to mess with it since it is fine

3. Hardware from custom & TouchSmart are not interchangeable

4. I don't know what to suspect here...

I'm, sorry, I didn't realize the touchsmart was a laptop.

What is your current PSU like in your desktop?

Question about power supplies.
When the computer is turned off, is the power supply still pulling power from the outlet? Was wondering if i could cut back on my power bill by unplugging it when i'm not home or w/e.

So from what i can tell when your computer sleeps it uses less energy to get in and out of sleep mode but uses more power in sleep mode, while when you hibernate it takes more power to get in and out of hibernation mode but uses less power in hibernation mode. Following that, at which point does...
