Review on 💡 RGEEK 24pin DC ATX PSU: Efficient 12V DC Input, 450W Peak Output Power for Mini ITX PC by Shane Mack

Hewegg.com calculated that my ATX i5 6600K with (2) 8GB DDR4 plus three hard drives requires 227W. So I bought a 250W model and blew it. Knowing I shouldn't have cut it so short, I bought a 450w model, thinking I had enough watts, and installed a 30A fuse to protect it. I turned on the computer and immediately the 30A fuse blew. 30A at 14V (charger on) means I drew 420 watts before the fuse blew. I went back to the 125 volt supply and hooked up my ammeter. Press the button to turn on the computer and my ammeter recorded a peak current of 5 amps at 125 volts, which is 625 watts. How could Newegg be wrong? Well, when the computer is on and idle, it only draws 0.4 amps at 125 volts, which is 50 watts. Newegg shows running power, not peak power needed to start. So. Keep an eye on your peak power and test it with an ammeter that records the maximum reading before you spend a bunch of money on DC power supplies that aren't big enough to power your computer initially.
