The UPS – Un-Interruptible Power Supply
The un-interruptible power supply does nothing to enhance your computing experience, that is, until the power company throws you a curve ball.
The UPS does two things:
- Keeps the computer operating for a while after there is a power glitch or a power blackout. Apart from the obvious advantage of giving you a chance to shut the simulator down “gracefully” (thereby preventing possible corruption) before shutting down in a controlled way, it also protects the equipment from the electrical punishment of the sudden on-off surge which can seriously harm expensive equipment.
- Conditions the mains supply voltage. This is simply a matter of evening out the dips and spikes caused by a noisy mains power supply. It does this by cutting in when the household voltage drops too low (a brownout) and suppressing high voltage spikes.
Once again, you pay for what you get. The more you spend on a UPS the better it will condition the supply and the longer it will last after a power outage before signalling that it is time to shut down.
It is always a good idea to rather have many smaller UPS’s connected to vital components than to have one huge unit for every device in the office.
Please note, the rechargeable batteries contained in UPS’s wear out after between 4 and 6 years, so this item should definitely be treated as consumable asset.
You don’t have to have one for your flight simulator computer(s), but it is false economy not to. To replace a High-end Graphics Card or a fast CPU will make a large unexpected dent in the wallet. Even the cheapest UPS is better than nothing.
