计算机间歇性关闭/重新启动。电源是否出现故障？

我的桌面间歇性重新启动。我确实查看了 Windows 日志，但它们并没有多大帮助。一个日志显示未能创建错误转储文件！

这是我的电脑信息：

I watched many YouTube troubleshooting videos, One pointed me to PSU testing.

I ran a stress test using HWiNFO64 and watched the voltage using HWMonitor(motherboard)
. As soon as I start the stress test  3.3V starts dropping to values as low as 3v(and even lower to 2.95v) See below:

上述情况是否意味着是时候更换我的 PSU 了？

感谢 cyBernard 的评论，我查看了 ATX 规格：

一般来说，电源电压必须始终在其标称值的 ±5% 范围内。然而，很少使用的负电源电压具有 ±10% 的容差。10 Hz–20 MHz 带宽中的纹波有一个规范：[3]

Supply (V)  Tolerance   Range, min. to max. (V) Ripple, p. to p., max. (mV)
+5  ±5% (±0.25 V)   +4.75 V to +5.25    50
−5  ±10% (±0.50 V)  −4.50 V to −5.50    50
+12 ±5% (±0.60 V)   +11.40 V to +12.60  120
−12 ±10% (±1.20 V)  −10.80 V to −13.20  120
+3.3    ±5% (±0.165 V)  +3.135 V to +3.465  50
+5 standby  ±5% (±0.25 V)   +4.75 V to +5.25    50

因此，对于 3.3 伏的价格，最低电压为 3.135，但我的 PSU 甚至低于 3V。
