Ok when i installed my graphics card i plugged it in then i went to turn on my computer after a few seconds it shutdown happend everytime i now have too k out my graphics card to ask why is it doing this? Is it somthing to do with the power supply?

The only information you gave was about the operating system. Can you tell us more about the graphics card-PCI, PCI-E, AGP, specific model ? Can you tell us more about your computer ? How can we tell if it might be the psu if we know nothing about the psu ?

Kx5m2g look at the ops previous posts. Bet he didn't listen to jam on the psu.
WinXp Amd 64 3000 Msi Neo2 Platinuim 1 gig ddr 400. When we cast a pebble into a pond we should look past the first ripple.

tom BEFORE you buy ANY card READ the side of the box for the specs that the card NEEDS to run CORRECTLY PSU Watts, amps on the +12V rail GOT IT???

let me re-write that ok my PSU 300W (12v 5v 3.3v) minimun for graphics card 400W or greater system power supply (with 12v current rating of 26a)
So does this mean i need a new PSU (power supply?)

How many times do you have to be told? Here's a few lines from your other threads:
Skip: "you'd best have a damn good power supply"
jam: "if your power supply is too weak & you install a card like the 9800GT, your whole system is gonna come crashing down"
Skip: "wait until you post back saying the system won't boot"
And the winner is...........Skip!
"wait until you post back saying the system won't boot"

ok sorry, im gonna buy a new psu then im sorry i didnt listen but i missunderstood the psu lable, im sorry Thankyou for your help, does anyone have any recommended PSU's i should get?

As jam and others tried to tell you before don't skimp on a psu. Wattage matters but so does amperage. Don't buy off brand psus. Ex I bought an antec psu years ago. That psu is in its 2nd computer and runnin strong. The cheapy was $15 less!

Is that alright to use to power my computer ect

"is that alright to use ?"
None of those units have the specs listed. You've been told several times what to look for & even quoted the video card box yourself: "min 400W or greater system power supply with 12v current rating of 26a"
Look at the PSUs that you posted again....where does it list how many amps are on the +12v rail? All it states is wattage & "Dual 12v Rails". Actually, it would be best to avoid units that have multiple +12v rails & get one that has a single +12v rail with high amperage.
And notice that 400W is the MINIMUM...do you really want to take a chance & just get the 405W PSU?
You really need to take the time to learn about PSUs. We (myself & others) have tried to explain to you how important it is to have a good PSU & Skip nailed it on the head when he wrote that you'd be posting about your system not being able to boot with the new card installed. So much for your friend who told you your current PSU would be OK, huh?
I realize you can't buy from newegg but here's an example of what to look for...notice the specs:

Take the time to do some reading:
http://www.playtool.com/pages/psura...

The PSU you listed shows "dual 12-volt rails," but, unless I've overlooked it, doesn't give any info about the amperage for the 12V rails. I would recommend checking out the many power supplies listed at www.newegg.com ... there you will not only get the full specs for each unit, but can read a lot of helpful reviews by people who have actually purchased the units.

jam, looks like your post beat mine ... well, the repetition of the info might help to reinforce the point for tom.

"well, the repetition of the info might help to reinforce the point for tom" I don't think so. tom4433: You didn't stae the the amperage for the +12V rail or rails, as has been noted many times already. For example, if you look at one of jam's links: http://www.newegg.com/Product/Produ...
Look at the output: It shows 41 amps for a single +12V rail.

When a psu doesn't list the "output" amperage don't bother with it.
