499元1050W白金电源？拆开驿晨宇玄武1050，我真没想到这么狠！

A 1050W 80Plus Platinum fully modular PSU for only $70 (499 RMB)? It sounds too good to be true. Is the Yichenyu Xuanwu 1050 a breakthrough in PC power value, or are they cutting dangerous corners where you can't see? [The Summary] At Lihuo Teardown & Test, we don't care about the sticker; we care about the silicon. Today, we put this aggressive newcomer to the test. We verify its 230V Conversion Efficiency and AC Ripple, then perform a full surgical teardown to analyze the EMI Filter, PFC/LLC Architecture, and Output Rectification. [Engineering Breakdown] We dive into the high-power circuitry: The Efficiency Myth: Does it actually hit Platinum levels under a 1050W load? PFC & LLC Deep-Dive: Analyzing the primary power stage and resonant control for high-wattage stability. Current Bearing Design: Examining the thickness of the PCB traces and the quality of the solid capacitors. Protection Logic: A close look at the supervisor IC and standby circuits. Is your RTX 4090/5090 safe? [The Verdict] We reveal the truth behind the price tag. Is it "Hardcore" enough for your next build?
