The power supply keeps things in your computer running smoothly. When they run well, you won’t even think about them, but when things go wrong, it can become very annoying.

The power supply doesn’t just run the power to the different parts of the computer. It needs to run different voltages to different parts, and besides that, it has to deliver them within a very tight range set out in the ATX standard.

Power supplies went through a phase of being extremely unreliable. This is because the actual parts are very cheap and standard and the profit margin in the power supply business is higher than almost any other computer part. The flooding of the market with poor quality power supplies led to lots of failures and complaints.

More recently, the problems in that sector have decreased, the general quality and build of power supplies has increased to a level where nearly any power supply will deliver what it claims it will and within specs. Most, but not all. If you have any questions concerning where and how to use Gpu Mining Hardware, you can make contact with us at our site.

As with computer monitors, power supplies are one part that does not need to be upgraded very often. The only additions have come from SATA specific power plugs and the additional P4 plug in recent years and even those are not always necessary.

So what do you actually need from a power supply?

The most basic requirement is that its power output can match the power needed by the components inside your computer. Each part has its own requirement and its own maximums and minimums on what it needs. The claimed maximum power for each voltage are added together to give the power rating for the power supply.

The main power user in the computer is the CPU. Some Pentium 4 processors are known to gobble lots of power. Hard drives use some power too, but no more than 10W each, optical drives even less. The motherboard itself uses some too. The other major user of power are graphics cards.
