GALAXY black gold BG-550L serves as the latest generation of mainstream products, rated power is 550W, 80PLUS bronze standard ATX power supply, in line with Intel ATX12V 2.3 design specification, support 115V-264 wide voltage.
Also, there is a BG-450L power supply, black gold BG-550L uses the design of the active PFC, supports 115V-240V input voltage, and the combined output power reaches 500W, it can easily drive the flagship graphics card.
Black Gold BG-550L is a half-molded power supply, which has a design of 24Pin + 8PIN, and the module line supports 5 SATA, 3 IDE, and two 6 + 2Pin interfaces, respectively.
Black Gold BG-550L power supply, module line, AC power cord
After-sales is still good, one year replacement, three-year warranty.
Come to a close-up
GALAXY black gold BG-550L, nameplate. I don't know why I didn't come to the 80PLUS bronze logo.
In the above, we have already mentioned that Black Gold BG-550L is a half-mode-compatible interface with 4 IDEs and two PCI-E module interfaces, why is the identification part use English? This is a bit hard to understand for my English bad mark.
Whether it is a native wire or a module wire, GALAXY is a brunette of the black gold BG-550L power supply. This is a wire entanglement, which is to prevent the wire. Parameters used by wire; 80 ° C / 330V / 18AWG
In addition to maintaining the previous semi-mold wire design, Black Gold BG-550L power supply also gives a short-term design IDE / SATA + PCI-E module wire to meet the needs of any ATX / ITX user, which is convenient for users.
Black Gold BG-550L is designed with 14cm fan design, specifications Wield12v / 2.5a, is a low-speed mute fan, while the function of small blank is to make the wind flow more concentrated, strengthen the internal heat dissipation effect.
Black gold BG-550L is the active PFC + Double Tube Positive Call + 3.3V single magnetic enlargement design, is a common solution in the mainstream level 500W
The PCB's workmanship is still nice, relatively reasonable layout, but the secondary test part has a trace of gesture soldering.
The primary EMI is more complete, 2 Y capacitors are directly AC connector of 1 X capacitor, while the discharge resistance on the X capacitor is replaced with a new IC.
Headphones EMI is quite complete; 2 model inductance, MOV pressure sensitive, 2 X capacitors, 2 Y capacitors, and red square fuses (specifications 350V / 6.3A)
The rectifier bridge model is GBU8J (600V / 8A), but it is also a pity that the rectifier bridge is not added separately, and the position of another rectifier bridge is still filled, and it can be composed of a higher standard bridge module.
Look at the main capacitor and PFC inductance.
PFC main switch (1) The main switch (2) of the double tube is used as the original GPT18N50DC original, specification is 500V / 18A
A close-up to PFC diodes, fairy tits rhrp1560, 600V / 15A
Two transformers
5VSB standby circuit
Master IC is Cu6808x
Secondary side
The end treatment of the wire is still nice, with a heat shrinkable package to reduce DIY workload
Group template
Summarize; the GALAXY black gold BG-550L is still nice, active PFC + Double pipes + single magnetic enlargement This solution is mature, and it can also guarantee that there is a good conversion efficiency, and the 14cm fan of the second power supply is believed to bring It's a good mute performance, and finally the power line is more thoughtful. While providing a large enough wire, it can also be effective and short-term to better compatibility with the ITX platform. Taobao has three stores for pre-sale of 310 yuan. At this pricing, it is still very cost-effective.
