How to safely discharge a power supply unit?
When we say that we are discharging the power supply unit, we are actually discharging the residual charges from the capacitors. Generally, Switched Mode Power Supply Unit (SMPS) is widely used in the PC. There are three methods to safely discharge the capacitors of the PSU. Turn off all the power supply to the PC from the mains.
What is an outdoor Uninterruptible Power Supply?
An outdoor Uninterruptible Power Supply is a power solution designed for critical applications where it's essential that equipment stays running in harsh outdoor environments and significant temperature variations, where an ordinary UPS would fail. Trust TSi Power for these applications.
How to discharge a PSU?
Based on Wikihow they suggest attaching a 10 Ohm power resistor between the black and red wires to discharge the caps. This method seems to make sense since you are adding a load across the caps to dissipate the stored energy. Has anybody tried this method of discharging their PSU before? A few days? A PSU will be discharged within minutes.
What happens if a component has no power source?
If a component has no power source to gain from for about 10 minutes it will be drained of power. Depending on the capacity this varies, but I'm sure you will be fine. The ZAPPED query is because of static discharge built up on you and between the component, this is not relating to the power query you first mentioned.
Is it safe to use a PSU if not plugged in?
Unless you are a child or have heart issues, that is. Normally, a PSU that has not been plugged in for hours is safe to work on, especially if you only replace a fan on the secondary side anyway. Handling a PSU is never restricted to the secondary side.
