I have 19 Dell Optiplex XE SFF computers that were manufactured between 2009 and 2013, and I've noticed a severe defect with insulation falling off of the wiring on the power supplies with early (<10000) serial numbers.
These power supplies are commonly used with Dell Optiplex XE and Optiplex 980 in industrial control and POS systems (e.g., restaurants). So far, I haven't found a recall for these power supplies.
Question: Is there any public information on the safety of Dell L280e-01 power supplies (e.g., recall or Date Codes/Serial Numbers where the defect was corrected)?
A detailed description of the defective power supplies follows:
I've inspected and cleaned up each of these systems thoroughly before booting them for the first time, and out of 19 there are 7 that have visibly cracked wires coming from the power supply:
I've had those set aside for a while and presumed I'd be able to fix them in the future. I finally disassembled one and found that the wires on the interior of the power supply were in even worse shape:
I should note that the metal part of the wires are fine, it is rather the insulation on the wires that is falling apart. Clearly, these are a fire/electrocution hazard and un-fixable; they will be disposed of. Any slight bend in these wires causes the coating to break, so it isn't just parts of these wires, it is the same along the entire length.
The specific wires with the breakage problem are labeled:
AWM STYLE 3385 18AWG VW-1 105 deg C 300V E236360 YUAN TAI
AWM STYLE 3385 22AWG VW-1 105 deg C 300V E236360 YUAN TAI
The wires on the power supply fan, the ground wire, and the positive and negative wires to the transformer and outlet plug are not breakable, nor do they have the same markings reported above.
The date codes of the Power Supplies I've found with this problem are R1003 (Serial No. 00002749), R1006 (Serial No. 00005511), R1009 (Serial No. 00007336), R1009 (Serial No. 00007540), R1010 (Serial No. 00009383), R1010 (Serial No. 00009700) and R1018 (Serial No. 00014545):
