OPTIARC AD-7170A Not enough power to burn.

My DVD burner in my Mac Pro reads discs fine, but burning always fails. I get the message there is not enough power. I'm wondering if having more RAM will help this probelm? I only have 4gb. I'm still on 10.5.8 because i fear upgrading my system when everything is working so well with my applications (except burning obviously). Is it simply time to buy a new burner, if so my choices are limited, right?

Hi-
Samsung is a popular drive, though I have no personal experience. I use the Pioneer DVR-116, and it is an excellent drive.
OWC is a Mac specialist, and only sells that which they deem acceptable for Macs.
I think you would be safe with the Samsung.
An optical drive isn't that hard to install.
Instructions are Here.
You must, however, remove the plate that is on the tray of the optical drive, or it won't clear the slot in the tower.
That is one note that is not in the instructions.
As for the scanner, for 800 slides, a dedicated film scanner may not be the best choice.
Current flatbed scanners offer some nice features, and many are able to make good scans of slides and negatives.
Current Nikon slide scanners can run a couple thousand dollars, so one would want to have good use for a dedicated scanner.
A scan service may also be a more economical approach.

When I plug in external hard drive to airport express it tells me not enough power for the usb port. I have the airport express plugged in to power

Airport express tells me not enough power to usb port for hard drive.
I do have power to Airport express plugged in.

The AirPort Express will not support a hard drive....only a printer.
If you need to connect a hard drive, you need an AirPort Extreme, not an AirPort Express.

HT4101 What if I connect the camera adaptor and it says there is not enough power to support it? (fully charged iPad)

What if when I connect the camera adaptor attachment and a message appears that there is not enough power? My iPad is fully charged and I was only downloading three pictures. ???

This might help ya out -> iPad: Using iPad Camera Connector with unsupported USB devices
If you encounter an issue trying to connect a digital camera through an unsupported USB device, try the following steps:
Disconnect the iPad Camera Connector from iPad.
Disconnect any USB device connected to the iPad Camera Connector.
Restart iPad.
Reconnect the iPad Camera Connector and then connect your digital camera directly to the iPad Camera Connector.
You may need to connect certain cameras, USB Audio, or MIDI devices to a powered USB hub for the iPad Camera Connector to detect them. Find more information on using the iPad Camera Connection Kit.

The iPod battery indicator is only a very loose approximation of how much charge there actually is left.

U3011t - Not enough power to USB ports

We are working with a U3011t and before this past Friday all the ports on the monitor worked. After doing re-imaging the computer, I am now receiving an error message that states there is not enough power to supply the USB ports. Any Ideas why this is?

The monitor USB hub is simply a receiver when the USB upstream cable is connected from the bottom of the monitor to a USB port on the computer.
The monitor USB hub should appear in the Device Manager. When I connected the U3011 USB upstream cable to my Alienware M18x-R1 blue USB 3.0 port, the Device Manager- Universal Serial Bus controllers added =
Renesas Electronics USB 2.0 Hub
Renesas Electronics USB 2.0 Hub
USB Mass Storage Device
Reconnect the monitor USB upstream cable to the monitor port. Then, connect the other end of our monitor USB upstream cable to every computer USB port and re-test. Also, test the monitor on another computer. If available, test another USB upstream cable. The ones from any printer will work.

Not enough power (New Keyboard)

I'm not sure if this was also a 10.4 issue, but has anyone had any issues connecting say... an iPod or flash drive to the usb 2.0 port on the new Apple keyboards? When I do so, it says not enough power to power the device.

Unfortunately, I really want to use my flash drive there... But the ones i have apparently are high-power devices.
Does anyone know which usb flash drives work with the new alu keyboard? Indirectly the error message says that some flash drives will work in these usb-slots.
It's pretty useless to plug it in at the back of my Mini every time I use it.

If you have ios 5.1.1 the output power is 100ma, on the iOS 5.0.1 the power output is 500ma! This may be the cause?

Not enough power...?

My problem is as follows:
Win 2k (Tried WinXP aswell)
CPU: AMD 900MHz
Mobo: Abit KT7A
MSI Gf4Ti4200
PSU: 300W
Various "high-end" games tend to crash my system, usually re-boots but sometimes only to desktop. I know that some games are buggy but this happens with all new games(except IL-2, dont know why).
The combined power of 3.3V and 5V is 180W on my PSU.
I've read that for this card it should be 200W.
Is the reason for these crashes my "weak" PSU. The PSU is Herolchi Electronis HEC-300LR-PT model. Max A for 3.3V is 20A and for 5V 30A.
These problems first appeared ~3 months back on a VERY hot day when all of a sudden my cpu crashed. At that time I had a Gainward Geforce4MX420 Golden Edition card. The Mobo refused to start with this card in. Changed the card to a old 12Mb card i had (AGP aswell) and cpu worked. Took the Gf4Mx420 card to the retail where they checked it and noticed that it worked in 4 out of 8 machines...Weird...
Bought this MSI card. All is well, except crashes ~every 3 minutes into games. Older games work well, especially 2D types like Jagged Alliance 2, Combat Mission etc. As well no probs when cpu on whole day, surfing etc...
Do you think that my problems are in my PSU? Something is weird with my Mobo aswell. I cant update the bios by flashing it. Get an errormessage "Not all spare parts listed" or similar when flashing it (correctly in DOS-mode).
Which one do you guys think is the probem? Mobo or PSU?
Dont have a lot of extra cash so dont wanna go and spend 100's of € on this...
BR, Jussi

Thanks for the tip Bas, but I dont think that is the problem here... The temp on my system is low, both system and cpu temp way below 50C... The fan and the heatsink are both new on the cpu, shouldnt be anything wrong with them...
I've actually noticed the following problem with my computer lately: When I start/restart quite often the Mobo wont find my DVD-drive(finds my cd-burner every time) out of my IDE-drives.
Do you think the psu doesnt give enough power at startup to the DVD-drive and it fails to recognize on the mobo???
VERY irritating ?(

Thunderbolt to Firewire 800 adapter not enough power

Warning to those who own G-Technology G-Raid Mini (Gen3) and a Macbook Pro Retina.
I just received my thunderbolt to firewire 800 adapter from apple yesterday. I hooked it up to the rMBP and plugged in my G-Raid Mini, the G-Raid Mini powers up, but then proceeds to make a beeping noise. The G-Raid Mini will not mount over bus-power thunderbolt to firewire 800 adapter. Although when I plug the G-Raid Mini into wall with power supply and then plug in the thunderbolt to firewire 800 adapter, the drive mounts.
It seems there is not enough thunderbolt bus power to mount a G-Raid Mini (Gen3)...
Has anyone heard otherwise? Can they confirm this doesn't work for them either.
Thanks.

Same for me.
Luckily I tested it is advance of playing a gig at the weekend using Serato.
Complete JOKE!
I can't believe that Apple hasn't considered the fact that the majority of creative professionals need high capacity fast mobile storage.
I suppose we now need to wait for 2Tb Thunderboth enabled SSD drives which by my reckoning will cost more than the MacBook Pro!!!!

Ipad error not enough power when i plug in a usb hub

whenever i plug in a usb stick i get an error power not enough

The iPad doesn't provide enough power in order for most USB sticks or card readers to work (the amount of power was reduced in iOS 4+), but you could try a powered reader. I don't know what you want to transfer off the stick, but the camera connection kit is only designed for transferring photos and videos - you can't transfer, for example, music or documents that way.

MSI 8800GT 1GB & Antec 1000w - Not enough Power?!

MSI 8800GT 1GB
MSI P35 Platinum
Antec 1000w Trupower PSU
Nvidia driver keeps telling me it has reduce setting due to there not being enough power.
I have used the power adaptor that came with it and used 2 different rails - still no joy.
The PSU has 4 x 12v rails each 18A. Total 12V capacity is 840Watts = 17.5A per rail so surely it should be happy?

Heres the problem...
http://www.hardwarecanucks.com/forum/power-supplies/3100-antec-tpq-problems-discussion-thread-3.html
The 8800 range looks to have an issue with misdiagnosing the power supply. Not just with Antec but a few other makes. The thread points to a beta drive 169.44. I have just installed it and bingo - it all works!

Can't update OS X - Not enough power

When I try to update OS X, an error message says that I do not have enough power, and that I should plug in my adapter and try again. This happens every time, even though the power is at 100% and the power cable is connected.. What can be the problem?
The update in question in which I am stuck with is the MacBook Air-firmware update for flash storage 1.1. I have Mountain Lion, and can't upgrade it to Mavericks before I have installed this update..

You could not possibly have gotten that error from the App Store if you downloaded the Mavericks Installer.
What at did you download? xCode?
The Mavericks Installer will run automatically once downloaded.
Here is where you should be downloading the Mavericks Installer: https://itunes.apple.com/us/app/os-x-mavericks/id675248567?mt=12
The button won’t say “Download,” though.

Ipod Video and USB 2.0 with not enough power

Hi all,
Ok, post number 2 for me. I have noticed another thing in the Ipod Video 30 gig that really has me wondering what is going on. I tested this out in various systems, being the analytical sort, and it seems to be that case. As long as there is enough power in the USB port to accomodate the Ipod, things are fine. Life is good.
But if there is not, even if you are compatible, in Windows, then things will be bad. First of all, your Ipod will freeze. That is bad. The second thing is that your Ipod will not come up as an Ipod in Windows, but will be a generic USD device drive. pretty awful.
So you have to reset the Ipod, and make sure that your USB port has enough power dedicated to it for the Ipod to be plugged into it. How much power is this baby sucking up anyways? On my machine at work, if I plug it in, and it only has a keyboard and mouse on it, it will not work. What is that?
Any help is much appreciated:>
Thanks
Grubster

You may have noticed that as a Windows user you get little to no response in this forum to questions. Wrong side of the tracks you know.
Anyway, I have found the same issues. I surmise that the real issue is that IPods are designed to be used with a MAC. There are of course literally tens of millions of Windows users out there so Apple was obliged for business reasons to accomodate them. The power issue is just one of the many problems Windows users have. Most non-hub and non-keyboard USBs will have enough power. Not all but most.
Keep in mind that I think MACs ROCK!! I would have had one if they were compatable with the machines already in my office. The IPod it great. The issues can be worked around.

Not enough power mi

so i bought a new Forton Blue 500watt a good psu....
everything should be powered sufficiently now... my micro still won't recognize....
anyone else have "power" issues?

"The Jukebox Zen will only charge if it is off as the USB port does not have enough current to power the Jukebox Zen while it is on."
Imaybe the micro has to be off when in the usb.... but it turns on automatically when inserted.

External HD not mounting since update 10.9, not enough power

Hi,
I have troubles with a Lacie Rikiki USB 3.0 external hard drive since I updated to OS X mavericks: when connected via USB, the disk starts to make noise, but the LED indicator stays off. I have tried several things, from formating the disk in all available formats to downgrading the Macbook pro (mid-2010, 13inches) to OS X Mountain Lion. The disk does not mount and does not appear in the disk utility soft. I have the same problem on a late 2009 iMac, on OS X and Bootcamp since the upgrade. Apparently the disk doesn't get enough current from the USB port, but I can't figure out why.
Thanks if you have any idea.
Rémi Grosjean

If that drive doesn't work on any Mac then it might be the drive has failed. you could also try a Y USB cable that connect to 2 USB ports at the same time to supply more power to it.
Mac notebooks have always had low power output on the USB ports. Mavericks might even lower that trying to save power.
