http://www.compucase-hec.co.uk/psu_xpower_light-480-580-680.htm

which is my current one will be enough to power the 8800gt or do i need to upgrade??

In my system i have a 4200x2, 2gb 800mhz RAM, soundblaster card, wireless lan card, and currently a 8600gt.

Yours is the 680??,,no problem even the 580 would do,,but the 480 might be iffy..

noo mines 480 Uhohhhhh

 

[mikzey01]

i dont really have many things on my computerrr thoughhh just one hdd and one cd driver plus the other essentails mentioned before

BUT the video card ,, the 8800gt ,, can draw 200+watts all by itself,I also am only running 1hdd a measly 2g of ram dvd etc,Plus if and when you upgrade in the future you will know that you have a reliable psu not needing replacement,,your choice..

For what it is worth ,,not to long ago I read an article here on Tom's that indicated that the 8800gt would run better [no bottlenecking] with at least a 2.6ghz cpu,anyhow try with what you have got if it works,watch the temps and fps,fine if not well then,,,,.

yer i no i need to upgrade the psu..but i just want to no if my curent sig will run it okay as i dont have the cash to purchase a new psu atm :S and i dont want to kill my computer alltogether either lol

According to your link, the 480 puts out 300W total on the 12V rail. This comes to 25A. A system with the 8800GT needs around 22A, so your ok. I don't remember how good "Hec" is right now, you might want to worry about how well it will hold up over time so close to its max output. I would say your probably safe.

BUT the video card ,, the 8800gt ,, can draw 200+watts all by itself

Were you trying to pull is leg? You don't honestly believe that do you? I believe the draw is around 8-10A, so thats 120W max.

Some good news at last! 😀 Thanks!! yh like i asid i really need to upgrade my PSU and will do soo as soon as i have the funds..but i got a 8800gt really cheap at £60 soo thought id grab it! 😀

75w from the PCIe slot + 75w from the PCIe lead = 150w, where does the other 50w come from?, subspace?, stop with the fud. An 8800GT uses 115w, need some proof look here.

 

[mikzey01]

gr8 thats better! 😀

No problem, happy gaming.

The Extreme PSU calculator shows that at most the system would pull 324 watts, with 20.1 A on the 12v rail, so you'll be good to go.

No offense intended. I was confused because I answered your question, and you said you were still confused. I gave you the power (in amps) of your 12v rail (25), how much draw a system with an 8800Gt needs (~22A) and said "so your ok". I'm not sure whats to be confused about.
