[12.83 lb] Best desktop computer I had yet

[1x SPHD15 Male] Perfect solution for running two computers (e.g., laptop and desktop) on a single monitor, with a bonus of using one keyboard and mouse for both. Simple A-B switch with lighted indicator showing which CPU is in use. Much superior to splitter, which increases interference and cuts resolution.

[1.5U] With this device there is no need to buy extra monitors or power down and switch cables when using two desktop computers. Simply push a button (or use the Hot Keys option) and you can toggle between boxes. Easy to set up and use and takes up very little space on my table. Included cables are generous in length to allow ease of routing.

[3.335 lb] I plugged the components that I wanted to share (keyboard, mouse, and printer) and the computers to share those components (laptop & desktop) and the KVM switch worked fine.

[2x USB-C (3.2)] Short review: I wanted to find a USB switcher I didn't have to worry (or even think) about at all. This is it. Long review: for context for the rest of this review, my use case is to switch a common set of USB devices (keyboard, mouse, and USB audio device) between a desktop and a laptop. I bought this unit after having a poor experience with a much cheaper USB sharing switch from another manufacturer. This other unit lasted about two years, then started to fail to switch between host computers, and also seemed to be allowing voltage from one host to pass through to the other. I'm not one to risk damage to the valuable computers I've got hooked up to these switches. I got rid of that unit, did some research, and picked this one up based on some other folks' recommendations. This unit isn't cheap, and seems to be marketed primarily toward business use cases, but so far it's working perfectly for my home office setup. It appears that I'm getting exactly what I hoped I was paying for: reliability and safety. I haven't had a single electrical gremlin show up since I began using this. It automatically switches the three USB devices to my laptop when I plug it in, and switches back to the desktop when I unplug my laptop. I'd recommend reading the instructions and making use of the power supply.

[12 VDC, 3A] Sharing a desktop extension monitor between two computers meant unplugging from one and plugging into the other. Now I have the computers plugged into the switch and the switch output goes to the monitor. Now I just push a button! The switch even automatically switches to the live computer if I turn one of them off.

[300 W] This the perfect UPS appliance for an office with two desktop computers, multiple external hard drives, printers and scanners. There are eight surge protected outlets, four of which are also uninterruptable power supply outlets. There are provisions for coax in and out ports, two cat 5 ports, one standard and one printer USB ports. It's compact and silent.

[700 W with IEC] As a DIY retiree, I have built a couple of desktop computers for myself with pretty good results. But there is something very reassuring in purchasing a customizable computer from a quality computer manufacturer like HP. My wife and I are using our recently purchased HP desktop in our home office and are very satisfied with its performance. It’s Windows 11 Pro OS updates without a hitch (albeit a tad too often— not HP’s fault). The computer is fast, quiet and reliable. The discounted price was an irresistible incentive to make this purchase. I highly recommend this desktop computer from HP.

[Lead-Acid] I've been using a UPS on all my desktop computers for over 20 years. I bought this one to replace a fairly old UPS and didn't want to replace the battery again. And I wanted to try CyberPower this time around. I also mounted it on a wall bracket to keep it and all the power cords off the floor. It's still a tangle of wires behind the UPS, but keeping it off the floor means less dust around my workspace floor and easier cleanup.
