The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

Standard ATX power supplies aren't designed to turn on unless they are properly connected to a motherboard. This helps to ensure that they can't power up and damage computer components if the plug isn ...

Configuring a custom gaming PC is both fun and rigorous work. First, you get to research your components –- case, motherboard, CPU, GPU, memory, storage, peripherals, cooling, and power supply unit.

Power supply. This is perhaps the most critical part of any computer that still gets overlooked by many. But the thing is, a PC can always be built without a graphics card (assuming that you picked a ...

The venerable ATX standard was developed in 1995 by Intel, as an attempt to standardize what had until then been a PC ecosystem formed around the IBM AT PC’s legacy. The preceding AT form factor was ...

An uninterruptible power supply (UPS) offers a simple solution: it’s a battery in a box with enough capacity to run devices plugged in via its AC outlets for minutes to hours, depending on your needs ...

A system that converts AC current from the wall outlet into the DC currents required by electronic circuits. A computer power supply converts AC into multiple DC voltages. For example, 12 volts is ...

Stop pairing expensive GPUs with cheap power supplies (and how to pick a good one) ...

In the past couple of years, it has become very evident that CPUs and GPUs have become increasingly power-hungry. We doubt this will change in the near future, so those who prefer super-powerful ...

Power supplies are a frequently misunderstood—and overlooked—PC component. Many users choose a PC power supply based on total wattage alone, assuming that higher is always synonymous with better.

1] Does the PSU fan spin on startup? Some users reported that their Power Supply Unit fan spins on startup but stops after some time. Others reported that the PSU fan does not spin even on startup.
