We are asked quite often about power supplies. The popular question seems to be "why are there so many different sizes available", sizes being translated into wattage. Well the various wattage's available are really to compliment different pc builds. Smaller, less power hungry systems can get away with a lower wattage power supply. Larger systems, built for productivity and advanced software aps, and gaming, will require more power.
So why is it important to have the right sized PS? A proper power supply, meaning one that can handle the power demands of the system, is important to the stability of the system for starters. Not supplying enough voltage to the pcu, board, video card, etc can be the beginning of bad things to come, mainly instability. Like the blue or black screen of death. All of the previously listed items have power requirements in which fluctuate up and down during the use of the system.
A recent call to our office rendered the question: How fast is my high speed connection? Well, whatever you do, don't take your ISPs word for it. Though you should expect speeds close to those advertised by your ISP for your particular package, in many cases the ISP doesn't deliver. Also, computer issues, bugs: hardware, spyware, viruses, etc can also be an issue that gives the apparent result of slower connection speed. Even router bottlenecks can cause really slow speeds. We just had a client with 30mbps speed from the ISP but a router that was good for only 11mbps.
A video card or graphics card is similar to a processor, but is specially designed to control the screen images or graphics on your computer. If you love graphics-intense games or videos, a high quality video card is a must for your computer system. Today's complex games simply will not perform to their maximum potential if your computer is equipped with an outdated video card or on-board video. Luckily, regardless of your system age, manufacturer, etc, the is a large selection of video cards that will help you achieve the highest levels of graphic performance. Buying a new graphic card for your PC can be daunting. There are many models available and options to consider. However, if you know exactly how you plan to use the card, you can make the process much simpler and choose the best video card for your needs, your system, and your budget.
