How big of a power supply should I get? / ram question

Here's what I have
K7T266 Pro2-RU motherboard
Radeon 9800 pro
2 40gb hd's raided
1 20gb hd
cd burner
dvd drive
Audiophile sound card (forgot the model #)
and i'll soon have either 512 or 1024 of kingston hyper x pc2700 ram
right now my power supply is 300w and i'm pretty sure that's not good enough.
when i install the new ram, i'm also gonna install a new power supply. how many w should it be, and any recommendations on brands to get?

When I look for any part I always try to find the best deal, price/performance.
Are you in the UK?
I have the JSP sprite PSU 550W and I would recommend it to anyone.
Its a 550w PSU, the make is JSP.

It cost me £26 on a special deal from http://www.aria.co.uk
Now look carefully at this PSU and tell me, does it look like the Levicom one.

If plugged into the power supply, should the Cinema Display A1081 standby light come on without being plugged into a mac

I was given an old Cinema Display A1081 a few years ago. I am trying to test it and want to know if plugged into the power supply, should the standby light come on without being plugged into a mac? I don't want to buy a DVI to mini display adapter if it isn't working. One thing I did do was plug Monitor power in and then the USB plulg into my PC laptop and my iPhone charger USB plug into the back of the monitor. I am able to charge my iPhone this way so I know that the power supply is working. But I can't tell if the monitor itself is workign as no ligths are on. (PS: I am purchasing my first Mac so I am a complete newb but very proficient with PCs) Thanks so much for your help.

Just a final question about Sleep mode - does this have any negative effects on the life or performance of the laptop? I'm so used to Shutting down the laptop each day that I worry about Sleep mode having some sort of drain on the components or something.
There are only two practical differences between Sleep and Shut Down:
1. Sleep will wake instantly, so you don't have to wait for startup.
2. Sleep will drain a new, fully charged battery after several days without being woken or plugged in. If you shut down, the battery charge lasts much longer. Obviously, if you only sleep it overnight, you'll still have plenty of battery left in the morning.
Don't sleep it more frequently than necessary, though. Frequently turning the backlight and hard drive off and on can shorten their life. Just do what's reasonable. I usually leave mine awake until I have to transport it in a bag, along with sleeping it overnight. On battery, I'll sleep it more often to preserve battery.

How big of a root partition should I have?

I am new to Archlinux and Linux in general. I recently installed my first Arch system but I have not yet installed a desktop environment for I am trying to learn the command line. I was planning on using this weekend to set up a desktop environment but I cannot decide which one to use, so I will try them all (or at least Gnome and Xfce). My question is how big of a root partition should I have to give me ample space to play around including having more than one desktop environment installed at once. I currently have a 20 GB hard drive with my root partition set to 4 GB.

How large of a backup drive should I get for my 500 GB MacBook Pro?

I have a MBP with a 500 GB hard drive. How large of a backup drive should I get for time machine backups? If I get a 500 GB drive will it just back up everything twice (as I have 250 used) and then delete the second backup every time it rebacks up so I will just have 2 backups? Or does time machine only backup changes every time it backs up? Thanks in advance.

Probably. See #1 in the Frequently Asked Questions *User Tip* at the top of this forum.
Should I just partition it 750/750? or maybe 600/600/300
Use roughly the same proportions as the data on the two Macs, adjusted for how you use them. If one changes lots of big files frequently and the other doesn't, give more space to the first one.
so I have space to put random files as well?
If you put important stuff on a 3rd partition, you can have TM back it up, too (unless the drive is attached to your Airport), but it will send you a warning reminding you that it's not a good idea to have both originals and backups on the same physical disk. You'll be much better off finding another way to back that up, perhaps archiving to CDs/DVDs.
Am I able to partition it and use it with my airport extreme?
Officially, no: http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
and: http://support.apple.com/kb/HT2426
But some folks (including me) are doing it anyway!
So if it works for you, just be aware it's technically unsupported, and you'll get little or no help from Apple if there are problems. And a future update may break it.

How to change the power supply to the CD/DVD Drive so that it is off by default?

When running on battery I often use the "Safely Remove Hardware" icon from XP to "unplug" the Mat****a CD/DVD drive in order to safe some battery life.(Does it?) I use Fn+Tab to bring it back to life. I wonder if there is a way to make my Notebook (M400) boot with the power supply to the Drive off by default. By the way, any idea where I can find the extra battery for the CD/DVD-Drive slot and at which price?
Thanks in advance for your help.

Hello Robert
If you check start page you will see that this support forum is not any kind of Toshiba support directly but user-to-user forum. But you are not alone and many users expect that some Toshiba support team sit in the office and wait to write answers.
Anyway there are many Toshiba notebook users with very good knowledge and also enthusiasts who try to help other guys with different issues and also share own experience.
Professionalism is not forum but action when you need assistance because of hardware damage or something similar. If you need competent answers and help every authorized service partner should be able to give you info you need. But please dont mix service partner and Toshiba because it is not the same.
Anyway I have found info that you can use additional (second expansion battery) and it should be batteries with part numbers PA3510U-1BAL and PA3510U-1BRL. I can not tell you how much it costs but you can find it alone using Google.
Back to your first question: If I am understand you right you want to save more power and because of that you want to disconnect ODD. It is nice idea but you have obviously misunderstood something. "Safely Remove Hardware option is there to help operating system and say this hardware part will be removed and dont exist anymore but it does not mean physically disconnection from other hardware.
If you need more power use second battery and enjoy your life.
If you have more questions you are welcome. Many users here have M400 and I hope in the future some of them will participate a little bit more.
Have a nice day! :)

How to recognize fake power supply for iPhone?

Hello,
last year in August I purchased at Amazon a "original" power supply plus USB-Cable for my iPhone 3GS. Now this thing sometimes works and sometimes it doesn´t. I called the vendor but he sees no responsibility for the artivle because it is out of warranty.
I told him that to me (and by comparing with other Apple-Hardware) the article looks pretty fake and therefore it does not matter if it is out of warranty or not - he sold fake hardware with "original" labeling on it.
Now I would like to verify my guess and see if this thing is fake or not. Do you have any idea how I can do this or what I should do now?
Thank you

To some extent it depends where the OP lives. In the UK and the EU warranties are expected to be for two years (though Apple still advertises one year). There are however, different definitions about what a manufacturing fault is.

How to check the power supply? iMac G3 233

How to do it?
Can i just take the case with the mainboard out and "short" the pins Power on (pin 8) with GND and check the voltages on the connector that comes out of the monitor case?
I know that the pin 8 is the power from articles about imac>atx case conversion.And i know that you can power up a normal ATX power supply by shortening two pins, and want to know if i can do the same with iMAc power supply. I don't want to fry anything.

Sounds like you have eliminated most of the possibilities, other than power supply board or motherboard. But it may also be the CPU daughter card that is faulty. I had one (233 MHz) that would run Mac OS 9 just fine, but it was unable to run Mac OS X reliably (crashes and freezes after a few minutes). I replaced it first with a 333 MHz G3 card off of eBay and later with a 467 MHz G4 card from the Fastmac booth at MacWorld San Francisco two years ago.
If you are comfortable disassembling the iMac to the point of removing the power supply board, you can layout the PS board and the carrier assembly (the thing you pull out with the motherboard, CPU card, and drives) on a table top. Then connect the power supply board to the carrier assembly, and connect the external power cord plug to the power supply board, and connect a keyboard with a power button to the carrier.
To measure the voltages, you can disconnect the 4-pin connector to the hard drive. If you turn it on using the power button on the keyboard, it will not start up with the hard drive not powered up (unless you use a bootable CD), but the system should be powered so that you can take your measurements.
Hope that works. Be careful with the exposed back end of the CRT. Keep any curious cats out of the room while you do this...

How to control HV power supply (0-5V control voltage)?

Hey there,
I (LV newbie) wonder how to control my DELTA ELEKTRONIKA Powersupply with Labview. The control interface is a 0-5V analog input to set the power supply's output current.
Also I want to get some feedback of the set power supply current from an second (GPIB-controlled) instrument.
So how do I have to program a closed loop contol (application is not time critical), cause it would be mixed up of controlling by analog out (0-5V) and feedback loop driven on the GPIB-Card?
For a first step a simple control loop to set the current and monitor it on an analog input would also be an assistance .
THX for anyone helping

Look in the example finder for DAQmx functions for analog input and analog output.

W520 power supply rating vs. performance question

I have had a W520 with the i2820 processor option and the quadro 1000 video for over 3 weeks now. I bought several spare 170 watt power bricks for it, but in one location I kept the 135 watt brick from my W510.
When I moved from the w500 to the w510, when I used a 90 watt w500 brick, the w510 would boot with a BIOS level message that said that the power supply was not adequate and that the machine would be stepped down to a slower speed. The reduction in performance was dramatic and noticable. (The w510 had the 45 watt consumption i920 chip and the more power hungry graphics)
When I use or boot the w520 with the 135 watt supply, there is no message. My benchmarks do not change from those registered when on the 170 watt power supply, starting with the Win 7 system benchmarks for processor and video. Further, the 135 watt brick is cooler to the touch than the 170 watt one under sustained usage (3 hours plus).
The question: given that the w520 in my configuration seems to draw less power than the hot and hungry w510, is the 135 watt supply going to work "as well as" the 170 watt one? As a briefcase lugger, any way to shed weight is valued.
Other considerations: I have no WWAN card installed, and have the CD/DVD removed and substituted with an SSD. The main drive is also SSD, bringing down somewhat the power requirements.

I remember another post, that I can't seem to find now, which refers to a software utility that displays wattage being consumed by the system. This would be quite helpful.
Couldn't that be used to study what is being used, and how much of a power adapter is needed to operate the system?
I am trying to come up with a solution for vehicle usage, and I am afraid, it will have to be a 12V to 120v power inverter with a brick plugged into it.
Another factor will be the amount of power consumed when recharging the internal 9cell battery and the external 9cell slice. Doing this while operating the system with WiFi / WWAN active will increase the demand.

MDD power supply and fan upgrade kit question.

Hello, Its been a few years since I posted anything here and I'm getting ready to (possibly) trade in my mirror drive door 1GHZ dual processor machine on one of the current imac-s.
I'm not real hopeful that putting much work into my current machine is worth it. Here's why:
1) crazy levels of noise - I wear woodworking hearing protectors when I surf the web. Listening to music on itunes is fine so long as you like a background of low level blow dryer noise!
2) I'm still running OSX version 10.2.8, I have been too cheap to buy the latest OS. I'm tempted to go out and spend the $119 on 10.5 but I only have the original 256mb of ram installed and since the min requirement of ram is 512, I know I'll need to spend an extra ~50$ on a 512mb PC2700 ram chip. My price tag to do a minimal update is rising...
3) I would love to neutralize the noise and install the Apple provided MDD power supply and fan retrofit kit that they sent me at no charge several years ago while I was still under warranty. But I never did because the tech at my local (Dayton Ohio) reseller told me that the kit only addressed high noise levels when rebooting in OS9. So I never bothered. Looking on ebay, I see where power supplies for G4's could fetch 75 or 100$ or so.
In summary, here are my questions.
1) Has anything come along recently to tame MDD G4 fan noise that is easy to install, cost-effective and most of all, something that actually works to decrease the noise?
2) To get the quietest, quickest performance with the current OS 10.5 should I cut my losses now and trade (or sell on ebay) my MDD, sell the new power supply and just purchase a new machine with the OS already installed?
Thanks a bunch in advance for any assistance...
from Bill.

Bill,
Carl has some pretty good points that I'd agree with - trying the replacement PSU and fans should quiet it down somewhat and replacing the stock main fan with a newer, quieter unit will also help. But I'm going to disagree with him on running Leopard on the G4's with a few reservations.
As you might notice from my profile, I'm running Leopard on my dual-867 MDD and find the performance acceptable; perhaps a little slower than Tiger in some respects but it does run well enough within the limitations of the G4's capabilities. The reservation I have about recommending Leopard on a G4 is the graphics card - without Core Image support (which you won't have unless you upgrade the video card) Leopard is going to tax the CPU more and may bog down in some tasks like Quick Look and Cover Flow.
In the end, whether to continue upgrading the G4 is a matter of use and economics. Tiger would be a fine upgrade with minimal cost and squeeze a few more years out of your G4 if you're not requiring software that needs an Intel CPU (like certain iLife '08 apps).

How big an external hard drive should I buy?

I am being told (by my computer) that I need to backup all my files - that there is a problem with the computer's internal hard disk. I thinkn I should run out and buy an external hard drive (What? you don't ALREADY have one? I think I head you all saying ...)
If the internal hard drive is 999 GB, I heard (?) that I should have at least 3 TB for the external hard drive.
Havign an external hard drive would be a great idea anyway, not just for backing up files but to allow the drive in the computer to run more smoothly.
I am making "statements" here - but they are really "questions." Am I making sense? Can anyone confirm the truth of what I am saying here?

Just to get a backup of your system any disk larger than your present usage would work, however you may as well look to later requirements. 3TB should be good enough for a while unless you have lots of HD video.
As to making your system run more smoothly, that depends on what you will use the drive for, generally speaking I would not use a backup drive to store data that is "in use" and the backup, if the drive fails you lose both data and backup. Have a seperate drive for backups and if you want to off load "in use" data to an external drive buy a drive for that purpose and do not forget to also backup that drive.
