12 Volt Low
7th Dec-2005
11.71 Volts is only 2.4% lower than Nominal 12.00 Volts Where are you measuring the 12 Volts -
Your Power Supply MAY NOT be the problem The Problem may be in your [Power Cabling] to Video Card This Card is a [Heavy Current] Draw from 12V - and requires [Separate/Dedicated] Power Connections
You probably have too much [Line Voltage Drop] PSU can deliver/supply proper voltage But with [High Line Voltage Drop] Card may not be receiving Proper Voltage
You need to Measure Voltage at [Card Connector] Not at the [Source]
A [Larger Capacity] PSU will not compensate for [Poor/Incorrect] Power Cabling
E=IR
If Line Resistance = 1 Ohm
And Current = 3 AMPS
Then Line Voltage Drop = 3 Volts So Video Card could be receiving [Only 9 Volts] while PSU is delivering 11.71 Volts -
Beefing up the Power Source will not compensate for Poor Wiring Practice Remember Line Resistance is not just the [Input Line] but is the [Return Line] ALSO
A [Good] Power Engineer treats the [Ground/Return] the same as a [Power Supply] [Power Wiring Integration] is more than getting a wire to a connection point -
Another factor in [Card Damage] is [Heat] It is a good practice to Leave the [Adjacent PCI Card Slot] Vacant to allow the [Onboard Video Card Fan] Room to breathe for [Proper Cooling] -
