  • 【轉貼】 技嘉兩款 80 PLUS 金牌認證的電源供應器存在爆炸風險,可能有設計上的瑕疵

    摘要:
    Gamers Nexus 花費了數月的時間,採購多台同型號的技嘉電源供應器(GP-P750GM 和 GP-P850GM)拆解並測試,發現了許多結構上的問題,其一是這些電源供應器雖然型號相同,不過內部的許多零件,卻是來自於不同的供應商,或許就是這個原因,造成了產品品質上的落差。
    Gamers Nexus 也在其官方頻道放上了詳盡的測試報告影片:

    此外,還有一項更嚴重的問題,那就是某些電源供應器即使超過負載,也無法正確啟動保護機制(OPP),而有些則是在尚未過載之前,就已經出現了燒毀的現象,有些人甚至電源供應器在爆炸時,一併帶走了系統內的其他零件。

    Multiple reports suggest Gigabyte's GP-P750GM and GP-P850GM power supplies could be at high risk of serious malfunction or failure. In some cases, these PSUs have even been going out with a literal bang.The issue was first noted by well-known PSU reviewer Aristeidis Bitziopoulos in his review for TechPowerUp in late 2020. In this review, he concludes that "Contrary to the Aorus PSU line, which was surprisingly good, this one is a disappointment…. For starters, my sample died during the over power evaluation, which is a great shame. The primary switching FETs blew up with a hell of a bang."He also explains the issue further in this Hardware Busters video.An exploding PSU is about as bad as it gets. However, the sample size is also as small as it could possibly be here, so further testing is required to draw anything close to a firm conclusion.
