the power supply is dictated some by the mother board, video card and cpu you have but mostly by the other periferials you have attached. Hard drives, cd/dvds , Network cards, USB devices ect. A 450 watt Power supply is usually more than adiquate for most home and many business systems. If you are building a server with SCSI drives or have added multi ide or raid cards to your system then you many need more but it is truly unlikely. A 450 would run quite a suite of components.

an average 450 watt power supply would handle that vid card and 4 gigs of ram, but little else

that cpu won't use a lot of watts but to keep it and that vid card cool, you'll need some good case fans

You really need a higher quality 500-550w power supply if you plan on adding several hard drives and optical drives, you can't go on wattage, better off looking at the rating on the 12volt rails

No. Try not. Do... or do not. There is no try.

I just wasnt sure because theyre selling all these SLI ready like 800 watters. and i think my motherboard is sli ready and stuff but do i need to make sure i get a power supply for that? and im just running an avg 300gig hard drive with like floppy cd and maybe dvd r

okay i was looking at some 550 watts on www.xoxide.com if you could show me which one you think is considered good quality that would be great.

The minimum recommended PSU for that graphics card is 400W, I agree with chewy, I would go for a 550W. You should also look to see what the amperage requirements are for the 12V rail for that card and what power connection the board requires if any.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Hmmm well here are the spec's as posted.
And a comment or 2 from the same site. I have been wrong before and I am kind of a newbe I started building computers
in 1981 and have kept up with the technology. Sorry if I miss led you.

Great GPU!!!
Reviewed By: Tech Mike on 11/23/2007 Tech Level: high - Ownership: 1 week to 1 month
Pros: The pros of this grpahics card far surpasses the cons, mainly because there are no cons. It is overclocked to 675 core clock. 512mb memory, 32 streamers (help aid in all the processes the GPU undergoes, and is not assigned certin tasks, in other words the GPU assigns them to optimize the full pontential of the GPU). Runs very well in vista too.
Cons: None for me, but for those who have trouble with heat you need to make sure you have adequate cooling, which is a duh, but alot of people only run 1 fan and yo uneed more than that. [u]Also like the other guy above if you have a PSU thats realy high power then you dont need it, it was designed to run on your old system, so no need to upgrade your PSU. That is unless your running like 10 fans, and have a 3.2ghz dual core processor like me.[/u] Other Thoughts: Buy it, and then when the next pay check come in buy another, then show off to your 8800 GT and GTS bubbies what it can do and they will scratch there heads in disbelief.

if you have little else running even this 500 watter would be the minimum I would try to use

http://www.newegg.com/Product/Product.aspx...N82E16817153052


something like this would allow even another vid card in sli mode and lots of extra drives

yea chew.. im trying to find as cheap as i can i dont exactly have a big budget for this comp. i was hoping to find one under 50... lemme know what you think of this http://www.xoxide.com/lo.html those are all cheap and atleast 550 watters

specifically http://www.xoxide.com/logisys-575w-2fan-psu.html
it has
1 x 20/24-pin Mainboard
1 x 4-pin P4
2 x 6-pin PCI-Express
2 x SATA
6 x 4-pin Molex
1 x 4-pin FDD
and the 2 PCI express would hold my gfx card and if i ever upgraded to another. im not sure what the other mean other than the mainboard ect. but thats cheap too. lemme know what you think

I just look at the specials, read a few of the reviews, go for a name brand with good specs, a lot of good reviews and on sale

a lot of people with deep pockets are real picky about brands, my pockets aren't that deep

BTW you are laming that cpu out with that cheap cas 5 ram, the amd64's need cas 4 for performance

I would rather have 2 gigs of cas 4 as 4 gigs of cas 5

now running the core 2 duo's stock it doesn't seem to impact performance much as the intel's have such a longer memory pipeline

Here are a couple of neat Power Supply Calculators:

They might help.
