Hi

I've finally finished transferring all my data to my unRaid box and have decided its now time to get a UPS, A power cut today proved the fact its needed as I live in the country lol.

My current spec is:
CPU: AMD Sempron 145 2.8GHz Socket AM3 45W 1MB L2 Cache OEM Processor
Crucial 4GB (2x2GB) DDR3 1066MHz Memory CL7 1.5V Unbuffered None-ECC
Case: Antec P182
MB: Asus M5A78L-M LX V2 Socket AM3+ onboard VGA 8 channel Audio mATX Motherboard
PSU: Antec 520W High Current Gamer Modular PSU
USB: Lexar JumpDrive FireFly 4GB USB Flash Drive
USB Header: StarTech 2 Port USB Motherboard Header Adapter

Drives:
/dev/sda WDC_WD20EARX (2TB)
/dev/sdc WDC_WD20EARX (2TB)
/dev/sdb SAMSUNG_HD204UI (2TB)
/dev/sdd WDC_WD20EARS (2TB)
/dev/sde WDC_WD10EARS (1TB)

/dev/sdf WDC_WD10EACS (1TB) (No data on and not part of the array, soon to be removed developed a clicking noise)

I don't have a Kill a Watt meter but I have something similar I got off eBay: http://www.ebay.co.uk/itm/280894930435

According to the meter the system ideal at 58.4watts and when all disks are span up and a parity check under way (Power Cut > Sad

) it draws 89.7watts with a recorded peak of 124.3watts.

I have space for 1 more drive (Once WD10EACS removed) and if I add 2x Icy Dock MB973SP-B (3 in 2) Hard Drive Enclosure I can get another 6 drives in the case and max it out.

I've done a little reading a determined I should go for a APC one.

Been having a look on ebay and cam across the following:

http://www.ebay.co.uk/itm/APC-1000VA-Tow...2a13ab7bd7

http://www.ebay.co.uk/itm/IBM-750-Tower-...2a21975039

Also came across this one, it has no batteries but if there not to expensive it may be worth it?

http://www.ebay.co.uk/itm/APC-Smart-UPS-...19d4ff7307

Would something like this be better suited for my needs, that's assuming it runs with unRaid OK?

The IBM UPS750THV unit with the APC 1000VA Cells looks interesting but would it be OK with unRaid.

Now my question is this, will these UPS allow me to to have my server, switch and main pc with monitor plugged into it and shut them down straight away in the event of a power cut with out problems, or am I pushing the UPS to there limit?

If need be I can just have my server plugged into the UPS and as long as it shuts down the server that's fine (I don't have a massive budget, possible up to £100-110 max, baby on route Smile

) just need that added protection.

Thanks in advance.

I have no experience with a UPS. I did do some research a year ago (also looked at APCs) and remember seeing someone say watch out with old second hand ones as if the batteries die they cost more to replace the the unit itself. Someone will have to confirm this for you.

I too have that cheap uk version of a kill a Watt. I don't trust it, but its probably fine.

Took some reading with my meter:

Server:
Low: 59w
Load (all drives spinning copying across network): 90w
Peak: 124w

Main PC:
low: 75w
Load: (Pime and defrag): 140w
Peak: 158w

Monitor: Constant 34.1w

Switch: Constant 2.6w

Total 320w

According to the APC 1000VA (SUA1000I) website that's around 22.2 min

http://apc.com/resource/include/techspec...u=SUA1000I

The IBM 750i UPS I listed earlier is also around 22min according to website.

http://www.apc.com/resource/include/tech...ku=IBM750i

Would the IBM probably work OK with unRaid as its listed specs are on the APC website (both units have APC site links in the auctions)?

Been using THIS one for about a year. Very good APC UPS, should fit your set-up perfectly! Peep out my unRAID set-up in my sig, I have screenshots of power draw...

I am using this: http://www.amazon.com/CyberPower-CP1000A...B000QZ3UG0
1000VA, 600W

Works really well with the unraid's ups plugin. Shuts down the unraid server 5 min after power outage if it's still out (you can set it to whatever time).

You can also set it to turn itself off after a certain amount of time, so all other devices such as monitors and stuff will turn off. And as long as you set it in the server's bios, when power comes back, the ups will turn itself back on and the computers will boot automatically.

I don't think batteries are that expensive, and AFAIK they are supposed to last a few years (3-4) of course depending on usage too
