NewDisplayName Posted December 18, 2017 Share Posted December 18, 2017 Could u recommand me any cheap UPS for ~120 Watt, if possible Rack Mountable 19"? With normal eu plug. (in and out) which is compatible to unraids buildin ups support? (via usb?!) Link to comment
ashman70 Posted December 18, 2017 Share Posted December 18, 2017 Cheap is not what you want for a UPS, the idea is that if there is a power outage or a surge you want the UPS to protect your equipment and you want it to do a good job. I am not sure what brands are common or popular in the EU, but in North America brands such as APC and Cyberpower are common. I would not recommend going with a cheap UPS you will only regret it when something goes wrong. Link to comment
NewDisplayName Posted December 18, 2017 Author Share Posted December 18, 2017 <100€. I dont need UPS for hours and we never had a single breakdown in power (i know in usa its other). So its just for "oh a truck hit the house" case. Link to comment
pwm Posted December 18, 2017 Share Posted December 18, 2017 Cheap can go a long way of protecting the computer equipment from electrical damage. But to get the equipment not just protected but still powered and running after a lightning strike normally adds to the price. The UPS shouldn't just protect from damaging voltage levels, but should also make sure that the equipment can be safely turned off when the battery runs low. So a UPS should preferably manage a number of things: - protect connected equipment from damage - preferably itself survive lightning strikes and other anomalies - supply clean power (reducing danger of hung equipment) - supply real sinus waveform and not some horrible modified sinus that produces extreme overtones on the power cables - support voltage stepup so the UPS and computer equipment can continue to run on mains even in a brownout situation (not so important anymore with computers with PFC-capable PSU) - give enough battery time that the majority of power outages can be bridged - give some form of signal to the computer equipment to allow automatic shutdown before running out of battery power Cheaper UPS normally have to fail one or more of the above requirements, so it's important to figure out what are "must" requirements.

TUMS Posted December 18, 2017 Share Posted December 18, 2017 The power flickered like 8 times in one day after a snow storm the other day. The ups was showing like 8 power loss events on it. I have 2x APC SMT1500RM2U. I wouldn't be without them and I sleep better knowing my servers are protected. Link to comment
NewDisplayName Posted December 18, 2017 Author Share Posted December 18, 2017 MUST: give signal to unraid MUST: survive long enaught so unraid can shutdown properly. That SMT1500RM2U seem waaaaay overkill (1000€) Link to comment
NewDisplayName Posted December 18, 2017 Author Share Posted December 18, 2017 Whats about this: https://geizhals.de/apc-back-ups-700va-bx700u-gr-a1236971.html?hloc=at&hloc=de&hloc=pl&hloc=uk&hloc=eu nvm its listed under rack mountable, but doesnt seem to be!? Link to comment

NewDisplayName Posted December 18, 2017 Author Share Posted December 18, 2017 Yea, around 80 watt. Yeah, so maybe <200€. But they have c13 and c14 connectors Oo Link to comment

I was just commenting on what I use and why I use it. I have lot's of devices plus 3 different servers I run off them. Link to comment
NewDisplayName Posted December 18, 2017 Author Share Posted December 18, 2017 Yeah. How do i know if unraid is understanding the usv? Link to comment
NewDisplayName Posted December 18, 2017 Author Share Posted December 18, 2017 What u guys think? https://geizhals.de/apc-back-ups-700va-bx700u-gr-a1236971.html?hloc=at&hloc=de&hloc=pl&hloc=uk&hloc=eu I dont really know why it says its rack mountable, but i guess i also could setit at the bottom or next to the rack. Seems like ~9-10 min at my scenario. If i set unraid to shutdown at 90%. Link to comment
unevent Posted December 18, 2017 Share Posted December 18, 2017 Rackmount options: APC SC450RMI1U 450VA/260W, 1U, 213€ TrippLite SMX500RT1U 500VA/300W, 1U, 239€ For tower options, CyberPower, APC, TrippLite in similar output range are 35-50% of the above. Any of those brands will work with apcupsd or NUT on unRAID. Link to comment
NewDisplayName Posted December 18, 2017 Author Share Posted December 18, 2017 Im not quite sure how do i connect c13? I have a rackmounted power thing with schuko. BTw the APC doesnt do "good sinus" things (stepped) if u look at review. But i dont know if thats important. Link to comment

The Tripplite has C14 input, 7 C13 outlets, 2 C13 to C14 cables. I suppose an adapter or stick with the tower units. Not many options in low capacity rack mount. From Triplite: UPS Input Connection Description - C14 inlet accepts user-supplied AC power cord with country-specific plug. Adapter Link to comment

If you want pure sine then suggest going with one of the smaller tower 'shoebox' units from APC, TrippLite, or CyberPower. CyberPower CP900EPFCLCD 900VA/540W, 148€ Link to comment

C14 is the inlet on the majority of computer PSU and on lots of monitors, while C13 is the corresponding connector on the cable. Link to comment

pwm Posted December 19, 2017 Share Posted December 19, 2017 1 minute ago, nuhll said: I dont know how this is helping me?! Besides i have now a ups with schuko / Schuko. Many UPS comes shipping with a couple of C13/C14 cables so the user just has to connect their devices directly to the UPS. And many UPS may have multiple output zones which is a reason for connecting directly to the UPS instead of through a power strip - some of the zones may be possible to turn off separately and some zones may just have surge protection but not be battery powered. It's mostly monitors with fixed power cords that are hard to interface with a UPS using C13/C14 connectors and will require an adapter cable. By the way - it's rather hard to know what "a rackmounted power thing" you mention is, making it very hard to supply good answers. It isn't even obvious if that "rackmounted power thing" is using Schuko male, female or both. Link to comment
NewDisplayName Posted December 19, 2017 Author Share Posted December 19, 2017 Yeah, sorry, english is not my mother language, so i dont know some words.. i just mean normal plug in eu if i say schuko.. So you basicly mean that even if its c13/14 there could? be adapters inside? Link to comment
pwm Posted December 19, 2017 Share Posted December 19, 2017 Yes, it's quite usual that you get a couple of C13/C14 cables with the UPS, allowing you to connect the PSU of your computer(s) directly to the UPS. It's mostly for USB disks and monitors with fixed power cable that you need to arrange some converter cable. Link to comment

S80_UK Posted December 20, 2017 Share Posted December 20, 2017 In case it helps some people... C13 and C14 in this discussion refer to the IEC connectors generally used for AC power inlet and outlet in PCs, monitors, UPSs and similar. C13 and C14 are specific designations for the connector types, although most will probably just know them as IEC plugs / sockets / inlets / outlets. Link to comment
