Hi,
My Antec power supply popped very loudly several times and bit the dust big time, and took out my Gigabyte K8Ns Ultra 939 motherboard. I verified the motherboard and there is also one cap that has popped on it. The top is vented. The cap is a 1000 uF 6.3 V Nichicon HM series. I just purchased a HE series cap from Digi Key thinking it was a good replacement since it was rated for 5000 hours. I just realized that the HE series has higher ESR compared to the HM series. HE has a rated max ripple of 840, and HM 1140. The impedance is 30 mOhms for HM compared to 87 mOhms. Is the difference significant enough to casue issues in this motherboard? I.e. will the HE series cap be good enough for this?
Thanks for any help and advice
