Checking the computer power cord is the first step to troubleshooting when it stops working. Faulty power supply can create a lot of computer problems, which is why technicians prefer to check PSU first while diagnosing PC hardware.
The following can be some of the common issues of system failure:
Another thing you need to check is the external switch. If it is located behind the rear unit; make sure that it is not off accidentally. Plug the PSU power cable into the plug point or surge protector, and power on the computer. Most models have an indicator light on the back of the unit that glows when it's on. If it does not light up try another computer power cord and a different socket to remove those items as the source of the problem. Following are some of the major things which show proper operation of PSU:
Use a paperclip to test a power supply: Another name for the paper clip test is the jumper test. It allows you to verify PSU functionality when it disconnects from the components inside the PC. It identifies some of the common issues:
Flip the switch to the rear of the PSU and listen to the internal fan. If you can hear the fan then verify the power supply is on. If your power supply passes the very amateurish paper clip test, then check on this:
If your computers are under warranty and think the power supply can be the issue, you need to take the manufacturer's support and warranty of desktop computers upon purchasing. If you're buying business computers as finished systems, it's better to use company resources to find faults in computer supplies and other components. Thanks for staying till here. There are different types of computer power cords available like c13 or c14 power cords and many others. Thus, while you choose which you should use, make sure to know the difference between them.

at is the difference between USB cords? Adapters, extenders, and other same cable equipment will create havoc on your signal. We all wish these things were simple as it just works. But, in reality, these things are very complicated.With advancements in technology, USB-C has become very dominant. It can move video, audio, raw data, internet signals, power, and more. It means people adapt their old stuff from older standards like VGA can do almost everything.
Choosing between USB-C to VGA Adapter Cable: Choosing the wrong adapter can have its consequences on performance, either immediately or in the long term. The other category is which people might not know. Where a poorly built adapter will fail easily. Humidity, corrosion, heavy use, these things can make your adapter useless. Brief history: There are various types of USB cords, one of them is USB-C. It is useful for sending data at high speed, communicating audio information, video information, and other necessary universal standards. Additionally, the recent version of USB 3.1 provides a connection with 10 Gbps of bandwidth because of its construction. The only drawback is communicating with several video signals simultaneously, including HDMI, DisplayPort, and VGA. But, when you are moving from VGA to USB adapter or vice versa, its properties will decrease. In other words, our video signals will keep moving via VGA. One of the major support we get from USB-C is it supports Thunderbolt 3. It provides 40 Gbps bandwidth and reduces power consumption. This is ideal for MacBook Pro and other similar devices. On the other hand, VGA ports are just 15 pin connectors useful on various monitors, video cards, and HDTVs. This format came into the market in 1987 than it went on to achieve success. Later, in 1999, DVI replaced it, later HDMI replaces DVI too. But, even this has its limitations. It even checks how it compresses RGB information and its lack to separate audio and video signals. Video Quality: Whenever we transfer data via an adapter, there is always a risk of video quality degradation or getting damaged. It's one of the major issues while copying signals from one format to another. Imagine you took a black and white picture and then passed it via fax machine it will add up some distortions in it, and then when you redo fax it, it will add even more. The same thing happens with adapters. If you are using a common 1080p panel, you will not have to worry too much about them. While purchasing these things, make sure about these factors. Also, VGA cables cannot carry this much amount of data at initial levels. Quality: The quality of VGA to USB adapters has a major impact that can even harm the quality of your signal. Loose connections can be very bad, which can be broken anytime. The thickness of the cord that is useful in an adapter is generally a pretty good guide for durability. You also need to check on the reversible design. It allows the adapter to flip or revolve easy operation, which is great for easily setting up your equipment. It looks like a small convenience, but for people who are using USB-C to VGA adapters, it is a huge jump up. Each connection has an in-depth connection so consider that too. While attaching cables with USB-C to VGA adapters, it can block out other ports on your devices. Low profile connection heads will probably add more issues to you. Compatibility and capacity: VGA adapters are almost everywhere. Both these adapters work by communicating with driver software using the device. Most capable developers design their adapters around drivers that are useful on different platforms. Also, not every platform is the same, and sometimes adapter cable developers build for non-generic drivers. We can also say that your work might or might not work, or there also might be some extra steps included. It depends on the type of adapter you choose. If there's going to be added steps, it's good to know them before time. Conclusion: While choosing a USB cord or USB to VGA adapter, make sure that you check the adapter configurations and their technicality too. Once you know the basics and importance of these adapters, it will help you choose better. Source: https://sfcableinc.blogspot.com/2020/12/choosing-between-usb-cord-to-vga-adapter.html The internet boom has brought a demand for Ethernet CAT cables. People rely on them for a simple LAN or WAN connection to distribute TV signals in the areas. They have replaced the traditional coaxial cables. However, figuring out which cable is suitable remains a question. There are several factors to consider, including data transfer speed, connection distance, shielding and foil wrapping, and cost.
So which category should you choose and why? Let us have a look: Types of CAT CablesGenerally, people prefer choosing from three types of CAT cable. That includes CAT5E Cable, CAT 6 Patch Cable, and CAT6A ethernet cable. Perhaps they do not know about the different types of cables available in the market. Let us compare and see the variations between them. 1. CAT 3 and CAT 5 Cable Fifteen to twenty years back, when hardware networking came in, category 5 cabling was in demand. As of now, CAT 3 and CAT 5 cables are obsolete. You can think of them as the first version in the category line. They have a transmission speed of 10 to 100 Mbps. Though CAT 5 is available and still in use, avoid using both. 2. CAT5E Cable CAT5E is an updated version of 5, unveiled in 2001. The 'e' symbolizes the 'enhanced' version. There are no material differences between the two, but performance-wise, 5E cabling can support a data transfer speed of one Gbps at 100 MHz up to 328 feet. Moreover, its stringent testing standards eliminate unwanted signal transfers between communication channels. 3. CAT 6 Cable CAT 6 cabling is the backbone of all networks owing to its performance and transmission speed. It has higher bandwidth than 5 and 5E types. Unlike the entire cabling category, CAT 6 patch cable is tightly wound and has a shield over its twisted pairs to prevent crosstalk and noise interference. Talking about its specs, it has a 500Hz of frequency and can reach the speed of 10 Gbps for up to 55 meters. And as better quality demands more price, it is more expensive than its previous variants. 4. CAT 6A Ethernet Cable The 'a' in the CAT 6A stands for 'augmented,' representing the advanced version of all data cables. 6A is a level up of its predecessor, i.e. 6 and supports the double frequency. The presence of extra copper and 23 gauge makes it thicker than cables 5E and 6. This thickness helps in eliminating crosstalk. The CAT6A Ethernet cables have a higher transmission speed, i.e., 10Gbps over a distance of 328 feet. 5. CAT 7 Cable If you are looking for a data cable with a transmission speed of around 100Gbps,type 7 is the most capable in the category line. Besides, it uses a modified GG45 connector, which, to a certain extent, helps with backward compatibility. Despite all this, manufacturers avoid it because of its previous Ethernet standards, and that no popularity further creates confusion that 6A is nothing else but 7, which is not. So if you are going for it, double-check the specs. 6. CAT 7A Cable An Ethernet cable with the highest specifications is CAT7A. However, it is not widely used and supports a few hardware options. But considering the speed, it supports 40 Gbps upto 50 meters, which is more like CAT 7. The bandwidth is 50% more than its previous one. Overall, its usage is niche-specific, and you would want to avoid it because it is the most expensive of them all. 7. CAT 8 Cable CAT 8 is the future of data cables. They are the only cables that meet the IEEE standards, i.e., have a frequency of 2000MHz with a 40Gbps speed over 30 meters. The high frequency denotes that these cables will have a shield. All these high specifications are the reason why it is an excellent choice for prospective buyers. The Right Choice?In our opinion, the answer would be 6 or 6E cabling. Though, the final answer depends on your needs. If you are looking for high bandwidth, CAT 8 can be the best. However, the price can be a challenge. CAT5E is enough for a small cloud-based network. CAT 6 and 6A have added efficiencies, and so on. Decide what you need, list your requirements, and choose wisely!

The final choice would depend on the type of signal from the video source, the number of monitors, and whether it supports dual-mode DisplayPort (DP++) output. Also, consider the GPU. It allows the usage of only two passive adapters, and beyond that, you should use active adapters. Probably because the GPU has two clock signals for passive adapters, with no freedom of their own. So, what is the perfect choice? To know this, let us first understand these adapters in detail. Types of AdaptersAdapters, aka dongles, are used to connect modern devices with old ports or vice versa. Generally, there are two ways to connect them, i.e., active or passive. Active DisplayPort Adapter Active adapters use an internal chip for conversion that makes it possible to convert both: single-mode and dual-mode output. It means the video source can be of DP++ format or others. They are ideal for graphic cards like AMD Infinity that do not support DP++ output on maximum monitors. Analog VGA and dual-link DVI can also power active adapters to convert signal levels. Owing to the additional chips, the active adapters are far more expensive than passive. Passive DisplayPort Adapter For a video source supporting dual-mode DisplayPort cable, use a passive adapter. It would then send video to a single-link DVI or HDMI monitor. The reason is that here instead of an adapter, DP++ performs the conversion. Besides, it does not support external chips. The two-clock sync signals per GPU further mandates the use of two passive adapters at most. Though it is cheaper than an active adapter, DisplayPort passive adapter is not the best option while connecting to multiple monitors. You got a gist of adapters. The next question is, how would you decide if the DisplayPort is an active adapter or a passive adapter? DisplayPort: Active or Passive?The easiest way to tell if an adapter is active or passive is by remembering a chip's presence. If an adapter has a video converter chip for better performance, then it is active. No chip means that the adapter is passive. Next, if the adapter has a small box for conversation chips, then it is active. A DisplayPort cable that is similar to a regular plug is mostly passive. Besides, all DisplayPort to VGA adapters are active. DisplayPort to HDMI and displayport to dvi adapter can be active or passive. Connecting to Multiple ComputersIf you are thinking about connecting your DisplayPort source to multiple VGA, HDMI, or DVI monitors, you will probably need an active adapter or splitter. Even if your video source supports DP++, you would require an active adapter. This is because some graphics cannot support DP++ on multiple monitors. Also, GPU supports at max two passive adapters. However, it depends on the device's capabilities, and thus, it is advisable to confirm with the graphic card manufacturer about the compatible adapter. DisplayPort Multi-Stream Transport (MST) hubs are also an alternative option for connecting multiple monitors to a DisplayPort video source. They provide better functionality. However, ensure that your graphics card supports DisplayPort 1.2 standards. Only then you can leverage the full potential of MST features. Inside News: Some GPUs/DisplayPort equipment specifically uses Active DisplayPort cables. Well, it is due to the timing and other design requirements. ConclusionChoosing an adapter does not sound like a big deal but choosing the right one definitely is. And to make that decision, you need to understand the types of adapters, their use, and if it is suitable for you.

Usually, they are used to connect with the single voltage AC with a local plugin. However, they can render both AC and DC. Moreover, they come in both structures: detachable and non-detachable.
The reason behind these tech specifications is that there are factors to be considered, but we never pay attention to it. We need an outdoor extension cord; we pick the one and use it. Well, that should not be the case. There are five types of extension power cord to choose from. They differ based on their capabilities, usage, quality, popularity, etc. So next time, if you're looking for an extension cord, choose the right one based on the list. 1. Red Extension Cords Outdoor extension cord are necessary for our outdoor decorating ideas. Their resistant power usually makes them a good fit for back lawns, gardens, and homes. While choosing a product for outdoor power supply connectivity, go for 50ft or 100ft variants based on your situation. These extensions usually have a vinyl cover, durable insulation to protect from moisture and temperature change. They are oil resistant too. Besides, they have a 3-prong grounded plug that further reduces the risk of electric shock and fire. These power cords have the right length and broad gauge, and thus you can use them for big projects. Therefore, if you require an extension cord for greater length, high voltage, and amperage requirements, go for this one. While purchasing it online, make sure to read the reviews. 2. Yellow Nema Power Cords NEMA Power cords are power cables used for AC mains electricity. They are popular in North America due to their quality and usability. As a heavy-duty cable, you can use it for gardening, toolshed, or powering up devices like computers, surge protectors, and receivers. These 125 Volts cables have strong prongs. Another benefit of Nema Power Cords is they are water-resistant, mostly. Some of the products also have a lifetime replacement warranty. NEMA Power cords have an LED socket indicator that lights up when there is power in the line. All these factors make it a perfect replacement for your overused power plugs. 3. Basic Black Cords These cords are the ones that we use for all types of electronic work. They are cost-effective, reliable, and handy when it comes to different lengths. Be it a birthday lightning decoration or an office desk; these extension cords are the best as it declutters the cord mess. They are highly durable and suitable for outdoor use, considering the technical point of view. These cords brighten the space with less behind the scenes mess in a small indoor project or outdoor use. 4. Small Extension Cord Pack Need short cords in a pinch? This pack can be the perfect one. For AC adapters and other indoor/outdoor purposes that require a loop of smaller ones, these tiny power pack cords come with various outlets. Also, together they work as a whole with multi-tasking capabilities. If you are a stickler for neatness or cleanliness, these extensions would be the perfect choice for you. Home, office, garage, or any other place that requires a little bit of cord can benefit from these small extension packs. 5. Long Power Cords Power cords mostly come with a definite length, but the lit plug makes a particular product different. Long Power cords mean it should cover a long distance, but there should be an indicator to know when the power is flowing through it. So while choosing a long power cord for rough or heavy use, choose the one with a double insulated conductor surrounded by an outside jacket. The insulation would ensure that the cable does not break even in extreme conditions. What to Choose?You can choose any one of these extension power cords but consider safety first. Faulty installations, improper use can cause disastrous accidents. Thus, before installing or purchasing a product, check all the technical requirements, ratings, and reviews.
