Default NewVid card power supply problem

Alright, I just purchased a leadtek 6800 but I havn't been able to try it out yet. It seems everything is compatible with my comp but I've run into a problem. It says (the vid card) it needs a minimum power supply of atleast 350 watts. It overlooked this because I didn't think it would be a problem being that my computer is new. When I opened my case my computer said it has 300 watts.

What will happen to it when I'm playing a game like doom 3? Is it going to slow down or something? I thought about shipping it back to Newegg after I try it out for a week, assuming I can do that, and buying a 6800GS since a pretty much bought the 6800 a day or two before the GS came out (bad timing and luck). Even though the spec sheet on the newegg site says nothing about a minimum power supply for the GS cards, I checked on both the Evga and Leadtek site and it also mentioned the 350 minimum power supply. Am I going to have to get a whole 'nother power supply unit just to play a few games? If I do it looks like more time researching for me This is turning into a real headache.

Thanks for any help, if you all want to read all of this

If you run out of juice your system will most probably reset while your playing Doom3 which would be very annoying. BUT sometimes your PSU will be capible of holding up, i have run a 6800GT off of a 320Watt PSU before with no problems.

So its up to you weither ya risk it for a lil while and see what happens (and save alot on Doom3) , or you purchuse a new 450+ watt PSU , there quite cheap now around £40 for a decent one.

So, when you say "risk it," will this actually damage the card itself if it cuts off in the middle of me playing a game?

Well, I guess Newegg wouldn't take my card back if it got damaged when I was trying to see if it would work right with my comp. Guess I need a new PSU if I want to have something in the 6800 range. This really blows...

I honestly have no idea what I'm looking for in a PSU. $91 is too much though. I thought about getting this b/c its cheap and 430 watts should be enough. Please don't tell me it isn't too cheap.

http://www.newegg.com/Product/Produc...82E16817153023

I don't have any idea how to hook this up either. I guess I could ask here or look at how my current supply is hooked up.

This is my comp btw-

Will that work with my computer, is there anything else I need to know about that PSU? One of the reviewers said it had a PCI-express connecter. I guess thats my main need right now...

alright, this may be a little too late, and I didn't want to start a new thread sine this is the same topic, but... I was looking on the PSU at that piece that supplies the main power to the comp and it has 24 little "ports" but the one I ordered has 20. Will it still work on my computer!?

Here is what I'm talking about (the new PSU that I ordered)-

if the mobo has 24pin thingy and the psu has 20pin it should work fine. If it doesn't then u can buy those converter thingys for like $10. (Changes the pins from 20 to 24)

So, it SHOULD work, as in no problems, right? Even though there are four pins left over that aren't used? Seems kinda strange. I guess I could put it in the middle of the attachement on the mobo to where there are two empty pins on each side...

One more question, the little four pin connecter that attaches near the PCI ports and such, does this work to power those aforementioned PCI ports, because the six port connector that comes with the new PSU has no place on the board to be plugged in. Of course, my old PSU had one too that wasn't used.

on PCI-Express nVidia has support for SLi so you might have extra pins unconnected on the top side of your card, PCI-E suports in itself more power then AGP so you may not have to plug in anything from your PSU into the card.

if you want to try out with your older PSU it should be ok, there is realy nothing that can happen to your card when you run out of power and the computer resets.

Vortec isn't bad. IT has nice reviews, it's 500W and it's only 80 bucks.

when ur card reaches maxium energy ( forgot wut that word wuts), ur PSU wont be enough. but doom3 is a pretty stressful game for ur card without a 350w PSU. i would get a new PSU if i were u, jus to be sure. a 420w psu only cost like $20 (cheapest i've seen). normally maybe 30-70. there are those expensive ones.

I've already bought one -

http://www.newegg.com/Product/Produc...82E16817104953

My current PSU has 300, this one has 400. Shouldn't be a problem for one video card.

The problem that I ran/running into is the main cable to the mobo.

You see, my comp has a 24 pin connecter and the new one has twenty

New PSU cable-

http://www.newegg.com/Product/ShowIm...y%20-%20Retail
That cable has 20 pins, my mobo has enough for 24. I know it will fit in there, but will it work?

What I'm trying to figure out is will the 20 pin work. So far somebody has said yes, which I hope is the true.
