8800GT power supply

Hi im wondering of buying the NVIDA 8800GT I have herd that there better then GTX and GTS. my 8600GT is running ok but I have just bought an 22inch LCD and i want full resolution. i got a 400wat power supply do you recon that will be ok? dont really want to buy a bigger power supply.

thanks

It depends on your other components, and the quality of the power supply. Often cheap power supplies with not operate at the wattage specified. If you have expensive gear it is always worthwhile spending a fair amount on the power supply. I think 10% of the total cost was said once before on the forums but I cant quite remember.

Quality psu and required amps
8800GT
400-450w
22-24amps
I run my 8800GT with a 470w @ 26amps

I would recommend upgrading to a better PSU.

Your Motherboard manual will tell you the
min and max it needs.
But 400 is a good size for the average user.
Testing it;s voltage output is important.
asus has a test,what is your MBD ?

This PSU is of excellent quality and offers more than enough power for your card and the rest of your system.

is there a program to see how much voltage Im using??

Yes

You have an asus motherboard.If you have a cd install "Probe"
or download it at asus.
You can also get a reading in the bios.
Heres an interesting link on the subject.

hey my mother board is an ASUS M2N-MX X series. cpu 3800+ dual core athlonx2. the power supply is 400wats Omni.

it says on the powersupply
DC |3.3v | +5v | +12v | -5v | -12V | +5VSB |
Output|--------------------------------------- |
Max |14a | 25a | 12a | 0.5a| 0.5a | 2.5a |
400watts |

thats what it says on the power supply

12a on the 12V rail is very low. Are you sure that's what it says. Because if that's what it says, you might need to upgrade.

yeh it is im using geforce 8600Gt now

Is this OK Boss ?

Where is that ?
Have you used asus Probe ? Are all settings given an OK ?
See my attachment here,

I think it's 21A, not 12A, since my calculations don't give me that 12A value. 125W max on +5V & +3.3V + 2.5W max on -5V + 6W on -12V + 12.5W on +5VSB = 146W. Subtracted from 400W gives 254W on the +12V rail, which translated to 21.167 ~ 21A. An 8600GT needs at least 18A on the +12V rail so if there wasn't enough power I'm sure it definitely wouldn't run. The 8800GT would need more power and the PSU I recommended before would do well.

I would get it but I dont no what to do with the old one sell it on ebay?? I tried probe but everytime I start it up just doesnt respond. i tried that site and put down all what i got and say 330watts it needs with the 8800GT??

the
http://www.extreme.outervision.com/index.jsp I did it and it recommends 341watts

Probe

Did you install the version on your mbd cd ?
Did you get an error message ? Wrong board maybe ?
It seems you might have the have the wrong Probe version,thats why haveing a motherboard cd is so important.
? Do you have One ? and a manual ?
Who installed your Motherboard ? Please answer this.
There might be other utilities to install on it.
As for PWS you don't skimp on this,your results indicate a 500 watt.
The old one doesn't have much value,save it for backup.
So do you know how to connnect a PWS ?
You need the manual or pay someone who does.
It's a very important to be done right and not block air flow.

the cd i got from the mother board just wont work for anything because im running windows vista.

My advice would be to buy a 8800GT (providing your PSU has a 3x2 pin power connector) and try it. It will probably be ok with a 400w PSU (it depends on so many things like other parts installed, age of PSU, brand, the list goes on). Worst case scenario your PSU isn't powerful enough and you have to buy another one, making you wait a few days to use your shiny new 8800GT.

oh k so wont blow up or anything. just wont work cause if worse comes to wores I will just buy better power supply

Check the Asus website, there might be a newer version which works with Windows Vista.

I'm pretty sure it can run. My friend runs his 8800GT on a 380W and it works fine.
