How do I Tell if My Computer Power Supply is Really Dead
In only 5 simple steps, you can easily determine if your computer's power supply is dead or if a drive or motherboard may be the guilty party..
1. Disconnect all drive power cables while your PC is off.
2. Turn on the power to your PC. If your PC starts your culprit is a shorted drive, otherwise… continue troubleshooting your power supply. If it appears that a drive is the culprit, you will need to use the process of elimination to discover the guilty culprit.
3. Disconnect all power supply cables (including ac cord from wall), leave one hard drive connected (500W+ models, connect two hard drives).
4. Insert a bent paperclip between the green and black (often wire #4 and #6) wires on the 20 or 24-pin motherboard power connector (do not allow this to come into contact with metal or yourself when powering up).
5. Connect your AC cable from the wall within nothing in between and then power on your computer. If the fan in your power supply runs when your psu is powered up, odds are that your power supply is fine.
"How do I choose the Correct Power Supply Wattage?"
One of the most important components to consider when building your computer or simply repairing a pc, is your computers power supply. The PC power supply is the backbone to any computer system, providing the fuel to run each computer processor, video card, hard drive and additional accessories that any given pc may have.
There are probably more budget models of pc power supplies on the market than quality, premium models. Generally speaking, when shopping for a computer power supply you get what you pay for. Cheap $20-$30 power supply models are not recommended for any application, so please resist the temptation to do so.
Many of these budget power supplies will fall short from fueling the power hungry computer components common in today's market. Poor quality electronic components are frequent to the budget power supply models, which can result in power fluctuations that can cause your pc to be unstable and even damage sensitive computer components.
PSU Wattage
When choosing the wattage of the power supply needed, you will need to estimate
the total wattage used by all of the PC components that comprise your computer
system. Make a tally of your components and add up the total wattage used and
multiply by 1 ˝ times. Ideally running a power supply at 30-70 percent of load
capacity for the best efficiency.
