| \t 4 | \t Radiator Fan | \t Original Taiwan Delta brand or ADDA brand, famous brand, model 8025 flow rate ≥50CFM, model 9225 flow rate ≥60CFM, the life time is more than 70000 hours under room temperature. The good quality and steady performance. | \t Copy brand radiator fan, flow rate low, not good radiator |
| \t 5 | \t FBT (Flyback Transformer) | \t High voltage diode 25KV, 30mA, high voltage capacitor 30KV, high voltage coil withstand 7KV, quality materials warranty. | \t Most is less this level, cost is just lower half than us |
| \t 6 | \t Radiation Fin | \t Radiation fin work surface thickness 5MM, 80W power supply radiation fin weight ≥220g, 150W power supply radiation fin weight ≥300g. | \t Thickness 2-3MM, the weight < 200g.150w radiation fin weight <270g. |
| \t 7 | \t The US Regulations Terminal | \t The US regulations terminal (connecting pins) metal materials is nickel-plated copper (not included nail), fasten to connect, not easy to oxidize. | \t No |
| \t 8 | \t Thermistor | \t Thermistor made in Taiwan, withstand higher load and big current, good quality and steady. | \t cheap one, cost is lower half than us |
| \t 9 | \t Protector Tube (Fuse) | \t Used US brand Littelfuse, explosion proof, stable quality and reliable performance, effective protection circuit. | \t Normal new brand |
| \t 10 | \t Safe Capacitor | \t Safety capacitor original imported from Japan. | \t No |
| \t 11 | \t Filters | \t Filter inductance ≥6ml, wire diameter 0.75mm, effectively suppress the interference of the power grid. | \t Small |
| \t 12 | \t VARISTOR | \t VARISTOR imported from Germany brand EPCOS (Siemens), reliable quality. | \t No |
| \t 13 | \t Rectifier Bridge | \t Rectifier bridge imported from Japan, 15 ampere | \t Normally 6-8 ampere |
| \t 14 | \t Power Module | \t Power module is US Fairchild power chip. | \t Copy brand or some Chinese brand |
| \t 15 | \t Rectifier diode | \t Rectifier diode is Japan brand Shindengen. |
| \t 16 | \t Transistor | \t Transistor IC adopt US brand TI or Fairchild. |
| \t 17 | \t Power Tube | \t Power tube is original Japan brand Fuji Electric |
| \t 18 | \t Filter Capacitor | \t Filter capacitor is all adopt Japan brand Rubycon, BlackGate, Nichicon etc. |
| \t 19 | \t Film Capacitor | \t Film capacitor is Japan Panasonic, or Xiamen Faratronic |
| \t 20 | \t High Voltage Connector | \t High voltage connector is US GE brand plastics, High pressure, corrosion resistance, effectively prevent the high voltage ignition. | \t Not high pressure, easy to spark |
| \t 21 | \t Hardware connectors | \t Hardware connectors is gold-plated copper, good contact, strong electrical conductivity, not easy to oxidize. | \t Normal copper |
| \t 22 | \t Sealing Cap | \t Black high pressure sealing cap is silicon rubber, good sealing, and preservative, good insulation. | \t Looks same, but in fact not |
| \t 23 | \t PCB board | \t PCB board is FR-4, epoxy glass fiber sheet, good insulation, high mechanical strength, copper foil thickness ≥70μm, big current. | \t copper foil thickness ≥35μm, can not stand big current |
| \t 24 | \t High Voltage Cables | \t Red high voltage cables is 40-50KV, GB Standard, good insulation, high pressure resistance. | \t Red high voltage cables is 30-40KV, no GB standard |
| \t 25 | \t Electric Relay | \t Electric relay is original Omron. | \t Most is other Chinese brand |
| \t 26 | \t Solder | \t Solder is 63 degree, high levels of lead. | \t Solder is 50 degree |
