Will my PSU power an 8800GT

[elrasho]

I have just ordered an MSI 8800GT 512MB, my PSU is a 525 Hiper which Ive had for just under two years. Will this have enough power to run the 8800GT properly?

 

[-Psy-]

Yes. My 600w PSU can run an 8800GTS fine along with a E6320 and 2 Gigs of RAM.

I have checked my PSU and have one 6 pin molex connector, how do I know which rail this is running off?

Don't worry about which rail (if you have more than one +12V rail). Just plug the 6pin in the card and keep things with motors (hard drive / fans) on a different cable. Usually a non-issue.

The wattage should be fine but check to see if it outputs enough amps. Nvidia says that a 8800GT needs 26 amps, I know this first hand because my original power supply had more then enough watts but not enough amps to properly power my 8800GT when I first got it.

Is that 26A on each rail or combined?

the card came today I'll plug in the single 6pin molex I have and see how it goes

26A being supplied directly to the card from the power supply.

Their power recommendation is what they want you to have for your system + their card, expecting the worst. I didn't see them specify that they want you to have 26A on a single 12V rail. You could meet their recommendation that way but it would also work if you had 2 12V rails (maybe 20 amps per would be safe). Rails don't add up exactly fyi. 2x 18A would deliver maybe what a 30A would but with limitations.

Those 6-pin connectors can deliver a maximum of 75 watts. The power is from the +12v rail.
75 = 12 * Amps
75/12= Amps
6.25 Amps
So wouldn't this be correct?

And the PCI-Express slot can deliver up to another 75 watts to the card.

example: Hiper 530
18A and 17A for 360 watts max on the 12V rails
360 watts / 12volts = similar to a 30 Amp rail (best case)
How much the PSU can pull from both rails at once might vary between units.

Ok, gotya. Thanks for the maths lesson Asus.

yay math...
