Trying to find out how much watts do i need for my new hardware.

By roise4000 ·
Hello there, I am about to buy some new hardware for my computer.

1) AMD Athlon 64 X2 6000+ Windsor 3.0GHz AM2 125W
2) GIGABYTE GA-M750SLI-DS4 AM2+/AM2 NVIDIA nForce 750a SLI ATX AMD Motherboard
3) CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

...but, i am worried about how many watts in power do i need to go ahead with the upgrade. The processor alone is 125w. My old Athlon is only 65w. I tried to do online power calculations, including this one: http://www.journeysystems.com/?power_supply_calculator

but it seems they are so out of date. This one doesn't even have my processor as an option, so how can i trust it. So one of my questions is: What happens if there is a shortage in power, if my hardware requires 500w power and i only have 400w power supply. The computer just will not boot up?!, or do i get all kind of errors, blue screens of death and other stuff while using the computer?

And lastly, if anyone has this similar configuration that i am about to upgrade to, pls share your opinion on how big a power supply should i get, i have a 500w wight now, i was thinking maybe getting a 800w or something, but again i dont wont to over do it, and just spend money for no reason.
here's a total of what is going to be under the hood:
-----------------------------------------
1x the above procesor
1x the above motherboard (GForce 8 series video card included)
1x the above RAM combo (2 x 2GB sticks)
1x DVD-Drive
1x DVD-RW drive
2x SATA drives at 7200rpm
1x ATA133 drive at same speed i think
4x colling fans including the processor fan
1x wireless PCI card

Don't skimp on the power supply

Power supply problems other than total failure are usually indicated by lockups, blue screens, and data errors.

It's much better to have too much power supply than not enough. Given what you describe, I'd recommend at least 600W if not more. This page and the rest of the article will help you make your decision: http://www.tomshardware.com/reviews/power,745-2.html

Purchase accomplished !

thanks a lot for the extra information.
I already purchased this though:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817341002&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-N82E16817341002

i hope i did the right choice, i dont understand the deal with this multi-railing and single rail... maybe i should have bought a PSU with a single rail, whats the difference?

Excellent choice

by NickNielsen In reply to Purchase accomplished !

About rails...

The easiest explanation is that a rail is a separate power supply within the power supply module. Multiple rails distribute the current load between voltage regulators, reducing both the load on any one regulator and induced transients in the DC output. Having multiple rails makes the output voltage more stable.

wow... good for me

My new comp is up and running :), I was able to use my old OS, which is great, saved a lot of time on installing everything back.

Problem: Windows sees only 3GB or ram, because of the 32-bit limitation, so i have decided to move up to a 64-bit XP, BUT i dont want to reinstall windows :), can i repair on top of the 32bit version a 64-bit version? If not, how does that /PAE switch thing work on the boot.ini for using the full 4gbs. I tried just adding the switch, but nothing happened... any ideas ?

32-bit XP will never see more than 3GB

That's the 32-bit limitation. If you want to go 64-bit on the same partition, you should do a clean install, not an upgrade. You could also install XP 64 on its own partition and set your PC to dual boot between XP 32 and XP 64.

/PAE switch is a fraud ??!!

what about this article:
http://www.tipandtrick.net/2008/how-to-enable-pae-in-x86-32-bit-windows-server-2003-and-2000-to-use-large-4gb-or-more-ram-memory/

and this:

P.S. Should i start a new thread about this...It's a different subject, i mean

Don't know

Wasn't aware of the PAE switch before this because I only have 2 GB RAM in my PC and never needed it. The KB article does say that it may not work with all chipsets.

You may want to start a new thread, only this time click on the "Ask a Question" button. You will probably get faster (and maybe better ) support.

probably not worth it...
