Why might a motherboard be installed on top of spacers?
Why are motherboards installed in the case using spacers? To keep the board from touching the case, spacers or standoffs may be used.
What should you immediately do if you turn on a computer and smell smoke or a burning odor?
If you see or smell smoke, immediately unplug whatever seems to be causing it. Smoking can also happen if your computer fans stop working properly. This can happen if the fans or vents become clogged with dust, making it easier for your computer to overheat.
How many pins does the CPU fan header on a motherboard have?
Fan connectors come in either 3-pin or 4-pin configurations. Most motherboards will have 4 pin headers you can use with either 3 or 4-pin, although some boards do have 3-pin only headers, though this is very uncommon.
How do you determine the wattage capacity needed by a power supply?
How do you determine the wattage capacity needed by a power supply? Add up all wattage requirements for all devices that will use the power supply and then add an additional 30%.
What happens if you don’t use motherboard standoffs?
You use the number of standoffs you need for your board. Assuming the backplate of the motherboard isn’t touching the case, no problem or else not using them can lead to an electrical short. Yes this can damage the motherboard and anything connected to it.
What keeps the motherboard from touching the case?
A motherboard is installed so that the bottom of the board does not touch the case. To keep the board from touching the case, spacers or standoffs may be used.
Why should tower cases not sit on thick carpet?
Don’t set a tower case directly on thick carpet because the air vent on the bottom front of the case can be blocked.
How much power does a load drawing 5 a consume?
How much power is consumed by a load drawing 5 A with 120 V across it? Answer:The question is asking about power consumption, which is watts. The formula for this is: W = V*A. So 5A * 120V = 600 watts 3.
Which two components in a system might make a loud whining noise when there is a problem?
Which two components in a system might give out a loud whining noise? In case the power supply is not able to provide sufficient power to the devices then it will whine after the power is plugged up for the first time. At times there can be a problem with the power supply fan.
Which type of boot authentication is more secure?
Which type of boot authentication is more secure? Power on Authentication, UEFI offers secure boot which prevents a system from booting up with drivers or an OS that is not digitally signed and trusted by the motherboard or computer manufacturer. For Secure boot to work, the OS must support UEFI.
What are two reasons to tie cables up and out of the way inside a computer case?
What are two reasons to tie cables up and out of the way inside a computer case? *It stops the cables moving, preventing short circuits if a cable is worn. *It keeps cables from blocking the airflow, required to reach the heatsinks and hard drives. Why should a tower case not sit on thick carpet?
What is the main obstacle to using passive heat sinks?
Passive heat sinks do not have a fan and instead rely on increased surface area and passive air movement to cool the component. Because they do not use a fan, passive heat sinks are 100% reliable.
Is 750W PSU enough?
Generally speaking, a 750W PSU is enough for a high-end PC build. Some online stores give us a small cut if you buy something through one of our links.
Is 500w PSU enough?
Most people really tend to overblow things when it comes to their PSU, be it for possible future upgrades or just so that they can feel safer, but in reality for a single GPU build in the tier of 970 or even 390 a good quality 500w PSU will serve them perfectly fine, even with a bit of OC both on GPU and CPU.
How do I choose a power supply?
For example, if the maximum power or combined TDP (total design power) of your system’s present components is 300 watts, a 600-watt PSU would be a good fit. In a high-end system loaded with components that may peak collectively at 700 watts, a 1200-watt PSU would work well.
