What is PMI related to SMPS/PSU

I am looking for purchasing a Dell desktop from their official website. In the PSU section of customise option there are multiple options for PSU/SMPS. Two otions are for 180W, and two options are 300W. I want to buy 300W. One is "300 W internal power supply unit (PSU), 92% Efficient, 80 Plus Platinum", and other is "OptiPlex 3000 Tower with 300W Platinum Power Supply PMI". The PSU with "PMI" in description is almost three times costlier than non PMI. I tried googling PMI in relation electronics, computers and power supply but I did not get any results. I asked on quora but the answers were off track "go with 300 PMI" "go with non PMI" "go with Dell inspiron, not optiplex". Nobody answered what PMI is. You talented people at wikipedia are my last hope. 2402:8100:315F:1070:BA0B:8EAA:D58C:5EDC (talk) 13:04, 28 April 2023 (UTC)

The only references to PMI that I've come across is for the Power Management Interface. This is how individual PSUs in a large cluster interact with the Open Rack specification. See [1] and [2]. If that's the case, then the PMI PSU either needs, or is capable of, drawing power from the 48VDC bus bars in an OpenRack system. I may well be wrong, but I would check very carefully before you buy a product that may not work or else has capabilities you will never use. Martin of Sheffield (talk) 13:41, 28 April 2023 (UTC)

@Martin of Sheffield: Thank you very much. From https://www.dell.com/en-in/work/shop/business-pcs-desktop-computers/optiplex-3000-tower/spd/optiplex-3000-desktop/ao3000mt_vp I want to get i5 16000, 16gb x 1, 512gb SSD class 35, 2 TB HDD, RX640 4GB graphics card, extra HDMI port and two 27" monitors. Which PSU should I get? Most of my use will be Microsoft office suite, and watching movies. 2402:8100:315F:1070:B0C0:C3F1:948:B74A (talk) 17:29, 28 April 2023 (UTC)

PHP Composer Documentation

I have been looking for and cannot find complete PHP Composer documentation. The request I've received is how to configure composer so it installs the best version of software for the current PHP installation. I've found examples of telling compuser to install very specific versions of software, but nothing that implies you can say "Install the best available that will work on my computer." 97.82.165.112 (talk) 14:45, 28 April 2023 (UTC)

I don't think there's anything you can do at present. See a brief report on the problem or a much longer discussion.-gadfium 20:55, 28 April 2023 (UTC)
