P5P800 Won't POST

[Guest]

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

Among other things, I just bought new ATX case, P5P800 w/P4 520 mother
board, 2 512MB DDRs, ATI Radeon 9250, Matrox Serial ATA HDD, floppy, DVD,
etc. and it won't POST. The CPU fan comes on and a green LED on the
motherboard lights up to show power is applied. Only thing that struck me as
unusual is that the 350W power supply only has 20 pins with the plug on the
MB has 24. The way the connector is keyed, it only fits onto the connector
one way .... buttttttt, it don't seem right.

Anybody know anything about the connector differences? I logged a support
request on the Asus web site ..... buttttttt, who knows, maybe they'll
respond.

Also, I don't have any experience with a SATA HDD. Do they partition and
format in a manner similar to an IDE drive or are there secrets to make it
easier?

suggest you check something like Tom's hardware. There is apparently a new
power supply design coming out and the P4 power supplies are different I
beleive.
For SATA drives XP treats it as SCSI. you need the drivers.

You have a mother board that uses the new ATX version 2 power supply.
Follow the link and read all about it.

Is the 2x2 ATX12V power connector in the upper left hand
corner connected ?

The 24 pin connector has four extra pins (+3.3, +5, +12, GND).
These were added for PCI Express powering.

Your board doesn't have PCI Express, as far as I know.
It is an AGP board.

This is the power information from the AGP 3.0 spec, for
power flowing through the AGP slot connector:

Symbol Parameter Condition Min Max Notes
Vddq1.5 I/O Supply Voltage IMAX=2.0A 1.425 1.575V 1, 2
VCC3.3 3.3V Power Supply IMAX=6.0A 3.15 3.45V
3.3VAUX 3.3V Auxiliary IMAX=0.375A 3.15 3.45V
VCC5 5V Power Supply IMAX=2.0A 4.75 5.25V
VCC12 12V Power Supply IMAX=1.0A 11.4 12.6V

The +12V feeding the AGP slot is limited to 1 amp consumption
through the slot connector. If any additional +12V is
required, a separate connector on the AGP card takes care
of it. Roughly translated, this means the additional +12V pin
on the 24 pin power connector, will not be of much use.
For the P5P800 only, that means a 20 pin ATX power connector
should be adequate to power the board. The board is, after
all, a P4P800 with a LGA775 processor socket stuck on it.
And the P4P800 uses a 20 pin ATX power connector.

Other members of the P5xxx family of boards, are PCI Express
based. More power can be drawn through a PCI Express slot,
but how much more I cannot tell you, as finding that kind of
detail without buying a spec is hard to do.

The power requirements in the manual states that you need a 24 pin ATX
power supply and a 4 pin 12volt plug. ATX version 2, on page xii in the
manual. Give it a look.

Page 2-28 says that you Can use a 20 pin connector if it can provide at
least 8A on the +12V lead and at least 1A on the +5V standby lead. I
have this board and it booted fine with a Zalman 400 power supply with
the 20 pin connector.

Depending on your cpu speed the P4 can use upto 100 W. PCPower and
Cooling suggested a 470 W which is PCIx ready and has the 24 pin
connector. I was tempted to try my old 350 W too but after reading the
requirements above gave up.

A good quality ATX (20pin) power supply min. 400-450W will still work
on this board due to not having PCIe on this board.

However a 24 pin eATX V2 will be needed on some 775 boards.
