power supply scrweing up usb

[Princess Ryiah]

is it possible that a keyboard uses more power than my power supply is able to supply? i have been working on this computer for almost 8 months now started with a pos system and now its a fairly decent gaming system (only thing thats bad in it is the processor which icant upgrade due to motherboard) so i know its using more of the power supply than it used to be. My question is is the copperhead mouse and tarantula keyboard i bought about three weeks ago using too much usb power that they actually turn off when im playing games sometimes. Its random and even happens when im watching movies it turns on and off and then its fine when im not using anything that wants my video card (which isnt THAT high end that its sucking all the power supplies power )..im not stupid with computers but this is fustrating me. Also i tried all different usb ports and i actually blew out the top 2 from the keyboard and mouse being plugged in now they dont work right so before i blow out the bottom ones (which are connected to the front usb thereby blowing 4 ports at once) should i just get a more powerful power supply (this one is brand new but a cheap one so probably doesnt supply much more than the old one)....HELP if you can thanks guys/girls..sorry this message is kinda wordy not sure what info is needed to help fix it.

As long as you have the usb keyboard plugged directly into the computer, then the usb port's power shouldn't be an issue. If it's plugged into a hub, make sure the hub is 'powered' (by a accessory power cord).

In the Device Manager, you can also check how much power each usb channel has, and how much each device connected to it consumes. Just look in the properties of each of the 'USB Root Hubs' listed under 'Universal Serial Bus Controllers', and in the power tab you should be able to check to make sure each channel has enough power. If one is overburdened, switch the device to a different usb port (from a usb bracket, front panel, or hub; otherwise it'll stay in the same channel).

Also be sure that in the 'Power Management' tab in the used 'USB Root Hub', that 'Allow windows to turn off this device to save power' is disabled.

ok ill chekc that thanks

Keyboards are extremely low power peripherals. It is likely that your PSU is being over taxed and your motherboard is prioritizing power consumption, keeping the vital system components running at the cost of the USB ports. What are you running in your system? Please include everything. All devices and peripherals. And what is your PSU?

Ok again at school but i know most of the system

ASUS Motherboard (ill pst exact model when i get home)
Pentium 4 3.06 ghz 478 pin processor
ATI 9550 /X1000 series 4x 256mb graphics card
17" CRT Starlogic primary monitor
15" LCD Dell secondary monitor
2GB DDR 184 Pin Ram (not sure of speed but i got it cheap from pricewatch.com so its not really name brand works fine tho)
Linksys wireless G WMP54G Version 1.4
SoundBlaster Audigy SE
80GB 7200RPM Primary Master IDE Drive (with xp what i normally boot with)
80GB 7200RPM Primary Slave IDE Drive (has steam and drivers backed up)
80GB 7200RPM Primary Sata Drive (has vista occasionally boot to)
160GB 7200RPM Secondary Sata Drive (mostly backups of movies and music in case if one of the others fails)
Mad Dog Dual layer DVD+-R/RW CD+-R/RW secondary master ide drive
Lite-On CD+-R/RW secondary slave drive

USB Devices usually plugged in
2GB Flash Drive or 4GB Ipod Silver in front (one of the two is almost always in)
Bottom usb on back (which uses same power as front usb but are only two i can get to owrk atm)
Razer Copperhead mouse
Razer Tarantula keyboard (i leave the second usb for the keyboard unplugged since all it does is allow you to use the 1.1 USB on the top)

When problem started i had it setup with
Keyboard (Both plugged in) on the top 2
Mouse Next one down on the left webcam on the right
512MB flash drive bottom left
2GB RCA MP3 Player bottom right

now only 2 usb ports work so i can only use my mouse and keyboard

And the psu i believeis 400 or 450 Watt not sure ill look and double check but it was only $30 so its prob one of those 2
the useless shit i put in nobody cares about
Processor fan and heatsink (generic taken from a dell 3200 if it matters)
Light up fan in the front where nobody can see it anyway but I only had lightup fans when i built it so i put one in
Blue Light Strip taken from my clear case and put into this one again not visible unless you look in the back or open it up
3 power splitters (so i have enough plugs for all the drives fans and lights

BTW it says "Cannot recognize device" when i try to use the top 2 usb ports now no matter what i plug in
Middle right one get no response of any kind Middle left oen connects and disconnect constantly (i tested with my ipo and keyboard and they both sit and connect and disconnect every 2 seconds) and bottom 2 work normally though it causes front usb to do same thing as middle left does. And this is all with that power save off (someone told me to check yesterday). Uh yeah im not stupid i put this all together myself from old computers and new stuff i ordered but i got no idea whats going on with my usb ports but i kinda use them (specially the keyboard/mouse) and i did disconnect the light strips and a few of the hard drives to see if that would help but it does the same thing anyway booting with just the xp drive having power.

That's borderline, it should be able to handle all of that, but 450 is a bit on the low side for that many components. You may want to try disconnecting/removing everything that is not essential to the machine's operation and see if the problem still occurs. If it does not, add components back into the system one at a time till it does happen again.

Of course, if the problem occurs with the strain taken off the PSU, then it might simply be the motherboard's USB channel being under powered. If you've got a spare PCI slot, you can get a USB card for relatively cheap.

Did you check that?

It might also be worth seeing if there is a monitoring utility available for your motherboard that'll let you check the output on all of the different power voltages, which might narrow it down closer to the psu without having to open up the case. If Asus doesn't have one (I'm sure they do), then there are plenty of freeware alternatives like Motherboard Monitor.
