Where did you get the idea that a 8800 GTS required 26 A X 12 V = 312
Watts? A 350 Watt supply is very likely to be all that is needed for
his ENTIRE system.

Where exactly are you getting stuck?

Looking up your board, it appears you have an Micro ATX integrated
board with a single PCI-E 16x slot. So barring any case
obstructions, are you able to fit it in the slot? You have to slide
over that white locking tab first you know. Be sure it's fully
seated, you cannot have it touching hard dries and what not and being
shoved up out of the slot.

Next lock the tab back, screw in the card, and connect one PCI-E
6-pin power lead from your PSU to the connector on the card. This is
CRITICAL for an 8800 GTS (320/640/512MB). Now power up, install your
drivers and get going!

You can safely use NVidia's latest Geforce driver instead of your
manufacturers'. They are in fact, mostly the same. If you
experience problems with lockups and blue screens, it's likely you
have an inadequate PSU (common with smaller systems like you might
have).

A GTS requires around 26A (amps) on the 12V rail (+12v1, +12v2, etc)
total for the system. This should be marked clearly on a label on
the side of your PSU unit.


Because Watts is completely useless as a factor for determining system
load. NVidia's guideline for the 8800 series is 26A on the 12V rail.
This is a combination of all 12v rails combined and is intended to
account for the average system utilization of everything including your
CPU/mobo/RAM, drives, other cards, and fans.

And that is what is wrong with Nvidia's guideline. They should simply
give a (realistic) power requirement for just their card, as it isn't
that difficult to work out the power requirements for the rest of
the computer. One customer may have a 65W processor, another 150W, and
a system guesstimate is a poor substitute for just giving the video
card power alone.

I get power measurements for video cards from Xbitlabs, and at least
that gives a card level value. Since their measurement is of one
card, it isn't going to be a very good representation, but it
beats "26 amps" in terms of giving customers information they
can use.

8800gts 99W to 109W (clock rate dependent), 98.2W/12V = 8.18A (ignoring the 3.3V rail)
When the computer starts, it is around ~40W, a drop in the bucket.
