Re: Help! New P5K rig powers up briefly

Put together my new machine based on a P5K Deluxe motherboard and a
Q6600 CPU; when I power up, the fans simply spin for a moment .

Here's the complete basic rig I set up:

* P5K Deluxe motherboard
* Q6600 Intel CPU with stock cooler
* 2 x 1GB Kingston HyperX memory
* 500GB Western Digital SATA drive
* XFX GeForce 8800 GTS graphics card
* SmartPower2.0 450 watt PSU
* Sonata II case

I did the following checklist:

* Ensured stock cooler was tight against motherboard
* Ensure that CPU fan cable is attached to CPU_FAN pins on motherboard
* Ensured that 24-pin power connector from PSU is attached to
motherboard
* Ensured that memory is inserted correctly, one in each yellow socket
(DIMM_A1 and DIMM_B1)
* Ensured that graphics card is inserted correctly in blue socket
* Ensured that PCI-E power supply cable is inserted correctly into
graphics card
* Ensured that SATA cable connects SATA 1 socket on motherboard to
hard drive
* Ensured that SATA power supply cable is inserted into hard drive
* Connected the case wires in the following manner (in such a way that
all wire labels face the top of the case):

--------+
Speaker | black wire
5v | red wire
--------+

--------+
PLED- | black wire
PLED+ | green wire
--------+

--------+
IDE LED-| black wire
IDE LED+| red wire
--------+

--------+
Ground | black wire
PWR | red wire
--------+

--------+
Ground | black wire
Reset | red wire
--------+

When I turn on the PSU switch, the motherboard light shows as normal.
When I then press the Power button on the front of the case, the fans
spin up for a fraction of a second.

Any help appreciated as to what might be wrong.

Unplug and remove the 8800GTS.

Attempt to power up system.

You should get stable fan operation, and a repeating beep code
that says "missing video card".

If that works, and then when the video card is plugged in,
it only runs for 2 seconds or so, you don't have enough power
from the Antec SP450.

The 8800GTS uses 9 or 10 amps from 12V1, and that is in 3D mode.
A hard drive, a CD drive, and system fans, add about 2.6A to that.
The SP450 really should have worked. But it won't take long
to run the above test.

If, with the video card removed, the fan still only runs for a
second or less, the next step is to check the push pins on
the CPU cooler again.
