Need a List of UPS for ReadyNAS Ultra 4 Plus unit

Can it be used the two USB ports to connect the PC and ReadyNAS?

No, but you can connect it to the ReadyNAS and then share it over your network. ReadyNAS, UPS, router/switch and PC would all need power connected to the UPS. The router/switch would use very little power and could be left to power off when the UPS battery runs out.

See this excellent guide by dbott67: Using the ReadyNAS to create a Network UPS for PCs

20 minutes at half load? Did you actually test or are you taking its word (from the LCD). See here for real world testing at near full load from tomshardware.com



Read more from the test tomshardware.com did discussing this UPS as well as others. Cyberpower also originally called the PFC units "adaptive sine wave", then magically changed to "pure sine wave". I confirmed with them in mid 2011 that there was no hardware change. Only a marketing change. Has something changed since then? Probably not.

Good data, claykin. My entire setup has changed so I'll have to do some testing again.

I have an 800w PC, it's monitor, the readynas, cordless phone, USB printer (which is usually off or on standby) Speakers, and a few other bits connected to my APC BackUPS ES-700uk. I Get 5 minutes tops out of it. But I don't care, as long as the NAS shuts down ok. No critical data on the PC. Use WinNUT to Hibernate on this system. Would like something with a bit more longevity, but don't want to have to use IEC cables, or have any more bulk.

I recommend you remove the printer and speakers from the battery side of UPS. Connect them to surge only.

They are, it's got 8 sockets. Not everything i listed is on the battery side. I should of made that clear in the original post. The only things on the battery side is the NAS, main PC, it's monitor, and the cordless telephone. The other bits are on the surge side.
