PSU 8pin generally is for MB 6pin is for PCIE, most 400W+ PSU have one or two 6pins nowaday. should use the adaptor come with the video card to convert the 6pins to 8pin.
You can fit your profile to a single normal distribution with two adjustable variables (mean and variance) and obtain a residual; then fit it to two normal distributions coexisting with four adjustable variables (two means and two variances) and obtain a residual. Run F-test to see whether the improvement on the residual justify the necessity of invoking the complicated model, i.e. two normal distributions coexisting.

如果只是比较2组的数据的话,你说的f test是anova里的多组数据适用把,当然2组的 话也不是不可以用。因为你的数据好像不能确定是不是normal distribution(因为样 本小)我倒是觉得应该就run个non-parametric test,什么wilcoxon rank sum test( for non parametric non paired data), rank test, wilcoxon rank test(later two for non parametric paired data)之类的。我说的不一定对啊,刚考完生统的人 路过。严重理论跟实践脱节啊!
