Changing Alienware's PSU

post #1 of 22
Thread Starter 
Hello

Do you know if Alienware has any special circumstances I should know when it comes to (me myself) changing the PSU they originally put for the computer?

My specs:
Processor: Intel® Core™ 2 Quad Q9550 2.83GHz 12MB Cache 1333MHz FSB
Power Supply: Alienware® 1000 Watt Multi-GPU Approved Power Supply (Norton Power)
Graphics Processor : Single Graphics Card - 2GB GDDR5 ATI® Radeon™ HD 4870 X2 – Dual GPU Technology
Memory: 4GB Dual Channel DDR3 SDRAM at 1066MHz - 2 x 2048MB
Motherboard: Alienware® Approved NVIDIA nForce 790i Ultra SLI
----------------
An internet guide stated: "Many name brand manufacturer PCs use specially designed power supplies that have been built specifically for their systems. As a result, it is generally not possible to buy a replacement power supply and install it into these systems. If your power supply is having problems, you will likely need to contact the manufacturer for repairs."

Personally I do not understand what could cause such things, since all my parts are very usual and commonly used. And the PSU I am planning to buy is Corsair HX1000W, which also is said to be very reliable.

The reason I am changing my PSU is due to the fact that I am currently in Japan, and the Alienware came with a PSU that has an Euro (German-type, not the common euro-plug) power cord. There is no equivalent in Japan for this,

http://www.volex.com/index.php?optio...d=23&Itemid=31

Volex VSC19, and it seems pretty rare for computers in general also. So of course the simplest answer would be to get a cord that goes to this PSU and is still Japanese, but I doubt it exists. (The PSU is an auto-switching one, so the voltage from PSU's side is no problem, only how I get it to go to the outlet legitimately). Until now I used it with an adapter that made the plug Japanese for the outlet, but I believe that to be causing problems to my computer (thread: http://www.overclock.net/ati/424230-...ml#post5076300).

Of course I can't be sure, and my video card could be broken also, but I heard that "faulty PSUs" can cause such problems often, and I am using it in kinda an environment where its compatibility can't be guaranteed.

Answers very appreciated

I dont see any problems in picking up a replacement psu. It was only Dell, Gateway, and HP that used a special psu for there builds till lately. Id say your all set to pick up a psu of your choice, but a 1000watt seems way overkill for your setup, a decent 6-750 watt would do just as good, if not a quality 550.

You might want to first consult Alienware on whether changing the PSU out yourself will void any warranties that your Alienware rig is covered under.

This is the exact reason I learned how to build my own. Dell wanted $300 for a 400watt PSU

Hello

Warranties getting void aren't a problem since I wouldn't be able to use them anyway due to their impossible-to-use services due to me being on the other side of the globe. So I am kinda shafted in that sense.

Why I have/why I want to have a 1000W is because I was planning to upgrade to 2 video cards later on.

What vid cards are you planning to upgrade to? Also what all other peripherals to you have hooked up to the comp? i.e hard drives optical drives, how many?

Just one Seagate 250GB SATA 3Gb/s 7200 RPM and one 20X Dual Layer DVD±RW/CD-RW drive.

I was planning to get an nVIDIA GTX280, since then I would atleast know the issue of compatibility with motherboard "possibility" would be history. I have grown some antipathy for ATI during this whole scene of trying to figure out whats going on, thus I doubt I will look at ATIs way in the future...

My friend keeps telling me that the chance of the problem being the whole Japan's electricity difference and the adapter not handling it right is not very likely... I guess I really need to just get to try it with another video card to try it with

stooop! dont do anything, Computer power cables are universal generic Jug Plugs that are used to power amps, kettles, toasters, and a bunch of other stuff, simply buy a jug plug from somewhere (or steal one from the kettle or toaster or other device) and plug it in., problem solved.

Your next problem is the voltage in Japan and whether or not you have the right setting on your PSU to handle it (ie 240v to 110v or whatever it is they use)

Out of your OP I couldn't really figure out what exactly was your problem.
Are you having issues with your GPU? Or are you just having a hard time finding something to connect your PSU to an outlet with?

For the latter, you should go to 2ch.net and ask about where to get the cable you need - somebody will probably point you at some obscure computer store

edit: I doubt the plug was causing you your issues. Also:
Quote:
One weird fact there was from the beginning was that when I format, Vista does not detect my 4870X2 and no drivers are installed before I spesifically download catalysts. This already a symptom of something weird going on with the vid card?
This happens with both ATI and NVIDIA cards for a simple reason - Windows only comes with a generic driver.

You can also bring it to a computer repair shop and they'll be able to swap out parts to see if the issue is in hardware or software.

Hello

Power plug my Norton Power Unit uses is this: http://www.volex.com/index.php?optio...mid=31&lang=en

And it is pretty clearly not the normal plug computers commonly use to my understanding. Thus I think it would be hard to find one of these from ny other appliances... althought it would be pretty cool to find it that easily

PSU should be able to handle it perfectly to my and my friend's understanding, as it says "100V to 250V" and "auto-switching" (as it doesnt have the switch you choose it from in some power units).

But yeah, I canceled order for new PSU. It just is too hasty to make a decision like that for 200+ dollars investment

BTW, and another mind-boggling annoying (yet expected since it happened before) thing happened; I put my old power source back (I had taken it out already for the new one) and installed newest chipset drivers for 790i and now the computer works again.

I have no idea if it was the chipset drivers, since I had them installed before too when it was problematic, only now I had formatted from before so I did not yet have the newest ones, only the ones WinUpdate installs.

But yeah, as I said in my other thread where I actually tell the full problem(http://www.overclock.net/ati/424230-...-broken-3.html), this happened before... after the 2nd day problems it started working suddenly. So I really doubt it will last... but it only creates a bigger problem for deciding if something is really broken or if its just some small glitch somewhere...

EDIT: Goddamnit I was right...
I ran 3DMark, played NWN2 for an hour or two while it worked fine... and when I shut it down, next time I put it on Detecting Arrays in POST was stuck again ages (first symptom), I re-booted, Windows doesnt open, just black screen. Third try I got into Vista, CS:S freezes after 10 seconds.
