20 Most Recent ASUS P5S800-VM Motherboard Questions & Answers


Bad Power Supply. Weak voltage power rail.

[There are three main power rails in the SMPS for your desktop computer.
A) The 3.3 Volt power rail
B) The 5 Volt power rail
C) The 12 Volt power rail ]

1) ALL of the LED lights on at once use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power.
Just depends on what Processor it.

Remove the Processor, and you will have power to light LED lights, and spin fans.
Of course without a Processor operating, you have No computer.

Replace the Power Supply.

Do you have a KNOWN to be good, Compatible power supply available to use for a test unit?

Need guidance in replacing, or suggestions for Power Supply's to choose from, post In a Comment.

does the system post, how far does it boot up?

ASUS P5S800-VM... | Answered on Oct 09, 2013


You need some expensive equipment to do this.

1. Electronically Erasibale Programmable Read Only Memory Programer 840 pounds minimum for a decent one.
2. Digitally Controlled Interfered Re-Work Station 3740 pounds
3. Computer Aided Design Software 1000 pounds +
4. Computer Aided Manufacture Software 1000 pounds +
5. Specialist Micro Electronics Tools 130 pounds
6. Specialist Digital Systems Tool Kit 322 pounds

You need to first remove 3 IC controllers from the motherboard using the Re-Work station, than insert them in to the EEPROM Programer and reprogram them using the software that cam with it. DO NOT touch these IC's as 1 spec of dust on a pin and they will never work again unless you have Concentrated Sulfuric Acid and Acetone which you you can mix for 12hours in a sealed high pressure chamber with argon (I doubt), or you could spend 4000 pounds sending the IC's off to be cleaned (not likely when you can buy them for 16 pound.

Throw in bin, or display through a video card PCI .. ok

I see it is the VM/S version, and not the Asus O.E.M. version above.
My thinking is the motherboard was made for a proprietary computer manufacturer.
Perhaps NEC or Packard Bell.

Using this line of reasoning, it is my contention that the graphics expansion slot is the same, and motherboard chipset; for the VM/S version, as well as the Asus OEM VM version.

Going further...............

Specifications:
Graphics Expansion slot -
AGP and 8X........AGP 8X

Motherboard Chipset:
SiS 661FX - Northbridge chip
SiS 964 - Southbridge chip


http://www.motherboards.org/mobot/chipsets_d/SiS/661FX+964/

So we know the motherboard will support an AGP 8X graphics card.
Another item you need to have knowledge of, is what is the Minimum power requirement; for the particular AGP 8X graphics card you are looking at......

Let's look at some examples,
(They are getting fewer, and fewer; as the graphics card technology has gone to PCI Express.
PCI Express has evolved to the PCI Express 3.0 technology now)

A) http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=853908&CatId=2234

Scroll down to - Features
-> Minimum PSU Wattage requirement

(Ignore of you are aware;
PSU = Power Supply Unit
The Power Supply's used in personal computers are SMPS.
Switched-Mode Power Supply)

MINIMUM power wattage requirement for the above AGP 8X graphics card, is 250 Watts.

Something I would like to impart;
Back in the day Power Supply manufacturers 'fudged' the True, Actual maximum wattage rating.

Actual maximum wattage rating, was more like 60 to 70 percent of what was stated.
If we use a 250 Watt PSU from back in the day, as an example; actual maximum rated wattage would be 150 Watts, to 175 Watts.
[Simple equation(?);
250 divided by 10 = 25
25 times 6 = 150
25 times 7 = 175 ]

Point?
DO NOT under power a graphics card!
A) It will not work right, or at all.
B) It will burn;
The gold plated contact pins on the bottom of the graphics card.
The contact pins in the graphics expansion slot.

Takes a while usually, but when done you can use the motherboard for a Frisbee.

Here is a Power Supply Wattage Calculator,

http://extreme.outervision.com/psucalculatorlite.jsp

Takes about 2 seconds for the page to fully load.
Need guidance in using it post back in a Comment.

It is the 'Rule of Thumb', to have at least 10 percent more power, than what is required.
Easier on the Power Supply, as it doesn't have to strain to keep up.
I myself would recommend a 350 Watt power supply, at least.

One more thing if I may;
LOAD THE SOFTWARE FIRST!
Load all the software that comes with the graphics card.
It will be on the Installation disk that comes with it.

You will be loading the Drivers, and user interface.
For a graphics card utilizing the ATI (AMD) technology, you will be loading Drivers, and the Catalyst Control Center.
For a graphics card utilizing the Nvidia technology, you will be loading Drivers, and the Nvidia Control Panel.

AFTER doing so, THEN turn the computer off, FOLLOW Anti-Static Procedures, and Physically install the graphics card.

Why?
Because when a device is installed on a computer that has Windows on it, Windows will 'break it's neck', to find suitable, matching drivers.

If THE drivers are not already there, Windows will match up one of it's THOUSANDS of generic, one-size-fits-all drivers.
This = No
A Driver conflict can result........

Windows: "Which drivers do I use?
These or THESE?"

For additional questions please post in a Comment.
Or Reply, at the end of this solution.

The best you can fit is an AGP 8X type card. They are difficult to find now, so the prices of decent cards are going up. Your computer is about 3 generations behind, You would get better graphics performance by buying a new motherboard, CPU and memory bundle. It would be cheaper in the long run, as you could then upgrade the graphics card in the future and then upgrade the CPU as well. You can still keep the case and other computer peripherals you already use. But if you want an AGP card look on the Auction sites.
