mainboards
Capacitor Endurance Time
Solid Electrolyte:
Fluid Electrolyte:
System Monitoring
4.7
Components for continous 24/7 operation @ +60°C
Operating Conditions:
Circulating air
(mainboard) max. 60°C
Usage 24h / 7 days
All onboard electrolyte
capacitors: Polymer type only
(= solid electrolyte)
Lx = effective endurance time
Lo = endurance time @ 105°C
(e.g. 2.000hrs)
to = 105°C
tx = capacitor surface temperature
(e.g. 68°C)
High Efficiency Processor
Core Voltage Regulator
for reduced thermal
dissipation loss
Note: Power Consumption
PCH
P max ~ 4.1W
P idle ~ 0.7W
Extra Heatsink
on PCH (Q87)
All voltage regulators =
switching regulators (high
efficiency & stable operation
within full temperature
range). No linear regulators
(low efficiency)
