Is it ok if my power supply isn't screwed in? in Power Supplies Posted December 9, 2020 13 minutes ago, BlueChinchillaEatingDorito said: To be fair, Dell is using the standard screw hole placements. It's just that they added the additional stylistic louvers which get in the way. So it is possible you can find an aftermarket PSU that fits in there perfectly. It's not like the placement of the power cord and switch is precisely in the same spot across all aftermarket PSUs. Right but if that bit had been just a bit wider more PSU's would fit perfectly.
