Well, it’s not so important for everything to be on the same wall socket as it is for them to be on the same circuit. I think of each circuit in the building/house as both power source and antenna. Both Furman and UPS should clean the power, but will they do it in exactly the same way? I don’t know, so I try to be as conservative as possible. I wouldn’t use a power strip to join them unless it does NOT have any kind of surge suppressor, because I read somewhere that it would do more harm than good in cases like this.
With 2 PCs and a server, it’s going to be a serious power demand for the UPS. That would mean a seriously large capacity UPS. My LAN contains 3 PCs (one which also acts as a server), a NAS device (also a server), up to 2 laptops, and up to 2 mobile devices. Most are in the office, with only 1 PC dedicated to the studio. Sometimes I need a laptop in the studio as well. Mobile devices have batteries, so it’s the same as having a UPS on each one, at least in terms of power interruptions. So that leaves 4 machines vulnerable. The machines that act as servers use linux and its ext4 journaling filesystem, so there’s a good degree of protection against disk corruption. The studio machine is win10 with an SSD, so it was the first to get a UPS. The win7 machine was next, and the servers share a UPS. The routers and telephones also share the UPS with the servers. That gives the whole network a bit of time.
One reason I use 3 separate UPSs is the physical distance between machines, but a more important reason is UPS management. Since the UPS has to be managed by a single computer (and vice versa), consider what would happen in the case of an outage when nobody is around. With a single UPS, only the computer connected to it via USB would get the warning from the UPS of an imminent power loss when the battery runs down, so only that computer would be able to execute a graceful shut down. The others would be taken by surprise, just as if there were no UPS, only a little later in time. This is what we’re trying to avoid. Still, I have my NAS device in that precarious position. But the NAS device can be shut down over the still-intact network if I’m around during the outage. Otherwise, it would take a hit. But as you probably suspect, it has dual hard drives arranged in a RAID. (I think it’s RAID 1) since both disks contain the same data, both have to fail in the same place for data to be lost. The odds of this are something like a million to one. Even so, the NAS is for archived files, and the originals are on the fully protected machines. My only real anxiety is knowing when to replace the UPS batteries.
Re: what you want to connect to the Furman. It looks OK. I’d consider adding the synth to the UPS is you have the spare capacity. Synths generally don’t draw much power. Still, I have a synth connected to the Furman, so I must be OK with it.
