Can my PSU handle it?

Edit:

I returned this psu and am looking at others I have the two near the end of the post.



I have a really good deal on this gpu but I think that It will need more power than my psu can handle. It looks like I am within the limits but just want to make sure. Going off of the requirements on the PSU 101 page here is what I need...
8800GTX...............................450W .........................30A

the psu that I have:

the gpu
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130072

let me know if it will overload my psu or not. just a correction to newegg's description of the PSU... It does come with 2- 6pin PCI-E connectors

Thanks for the help!

just an update

I also have been searching for what can happen if i over load the psu. Is there a good chance that I will fry anything else? ie. motherboard, ram, cpu, gpu... I don't want to risk my new system because i didn't want to change the psu.
 
All you need to do is read the specifications it will tell you ^^

Minimum of a 450 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 28 Amps.) Thats for the GPU

Your PSU

500W, ATX12V v2.2

It should run fine tbh

If you dont want to risk your build then why not go with a new PSU? I recommend anything from Corsair there brilliant for GPU's (make sure you go over 500W though for your GPU etc)

getting a new psu is a possibility but I have to return the one that I have and then pay about double for a better one. I just wanted to get some opinions on what I had first before I went on spending more money. thanks for the reply!

No problem man! Your current PSU will be fine but id buy a new one just to be on the safe side you never know eh? ^^
 
ok so what next?

Alright so I sent in the Rosewill with an RMA for a refund. what next? I looked into a few good psu's in the 650 watt range and the amps that I need for the gpu and I still need a bit of help. Here are the two choices:

CORSAIR:

Antec:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371015

both seem good to me but I wanted to see what the difference was between having a single rail at 52a on the 12v or having a triple rail with 22a,22a,25a totaling it to 69a if I can calculate that right. My card needs 2 6pin pci-e connectors if that makes a difference.

feel free to add any more psu's that you feel would be good. I'm looking for one under 90 if i can!
 
It most likely will. It's rather difficult to actually get all the components of your computer to draw their maximum rated power.
 
So does anyone have an opinion whether the triple rail is better or the single rail? or will it make any difference since I need 2 6pin connectors for the gpu?
 
A single rail will provide the most stable/clean power. There's nothign wrong with multiple rails however, as long as the amperage/wattage is even or nearly even across the rails. (eg. each rail has 18amps, and maybe 150 watts)

No domestic PSU is a true multi rail design. In fact without EPS12 certification, PSUs with an electronically split single rail actually suck. That is because under ATX design standards, 12V+1 is dedicated to the CPU and therefore not available to the rest of the 12V requirement.

Avoid Diewill sorry, Rosewill.

Get the Corsair.
