First Malaysian electric king 300 nameplate
The first side of the power supply specification nameplate on the side of the power supply, in the nameplate, in the nameplate, clearly indicate the current output of each output circuit, and we can also have a nameplate to see the power supply is a double road + 12V circuit. Output design, the total power supply is 300W, although there is no peak power, the current value of the dual + 12V output circuit can reach 20A, and the total output of 250W can be output, which is sufficient to support high-end discrete graphics such as HD6870, GTX560Ti.
Part of + 3.3V and + 5V, the two currents can reach 18A and 15A, respectively, even if they have a large number of USB expansion devices and plug-in hard drive discussion.
Anti-counterfeiting sign
At the bottom of the power supply, there is a security-offic authentication of the primary horse, you can use the product number to log in to the primary horses, or you can call it.
Snake skin wrapped wire
Wire output part
The primary price is not high, but the wire portion is still unambiguous, and all wires are wrapped in snakes. The wire contains a 6PIN + 2PIN input line for the graphics card group SLI, and a CPU uses 4 + 4pin line, and there is 3 large 4pin and 3 SATA interfaces, which can meet most of the player computer platform power supply needs, and The wire length is also sufficient to support the back line of the chassis.
Internal structure and heat dissipation
Internal construction
The program adopted by the primary power supply 300 power supply is the active PFC + Double tube origin + double magnetic circuit amplifier +3 group independent output, from the whole, the material is quite in place, the layout of electronic components is reasonable, the wire of the wire is also passed Optimization does not create a crowded and messy situation.
