Rectifier bridge: 800W PSU uses single rectifier bridge with heat sink, the heat dissipation is better and the working temperature will be lower. 1200W PSU use 2 rectifier bridges in parallel without heat sink, the over current performance is better and better impact resistance. Because the PSU does not have PFC circuit, the peak current of the rectifier bridge is relatively higher, it needs higher impact resistance.
Input main filter capacitors:800W PSU uses 2 PCS 200V1000uF,1200W PSU uses 2 PCS 200V1500uF, the higher of the output power, the bigger input capacitors required.The peak voltage after rectification of 220V AC voltage is 311V,so 2 PCS 200V capacitors connected in series is enough
Delivered quickly. Packed well, nothing was wrinkled. Everything is neatly done, a pleasure to collect. It took about 3 hours to read the instructions and assemble. the power supply is cool! I recommend both the power supply and the seller
Very fast shipping, very secure packaging! Everything you need to assemble is there. Only a AC power cable is missing, but it fits from any computer. good device! Thanks to the manufacturer and seller. I am very glad!
The product was packed in a foam box, wrapped in plastic, with all the necessary accessories. It worked at its function. Hope the product is of good quality and durable with times.
Arrived 26 days. I compared the readings with YR1035 + (it has a scale of 4 decimal places), the difference in thousandths is 1-2 digits. Pleasant to use it
