My system is: http://ark.intel.com/products/56413/Intel-Server-System-P4308CP4MHGC

Dual 750W redundant power supplies
Dual Xeon E5-2630v2 CPU
Up to 16 RAM DIMM (currently 8)
Up to 8 7200k SATA HDD (current 5 + 2 SSD)
1x DVD Drive
3x PCIe Cards; SoundBlaster, 4 Port USB 3.0, ATI FirePro 2460 Quad MiniDP

Only need UPS to support shutdown of system (enough time to save VMs state) and possibly UFB ONT (~15W consumption) / HG659 (<24W consumption) router for the same amount of time to send alerts etc.

I'm currently looking on PriceSpy so should I be safe to go for a UPS rated for >800W and up to around 10min (less for lower wattage)?

Also looking at: http://www.pbtech.co.nz/index.php?z=p&p=UPSBLZ02200&name=Blazer-II-2200VA1100W-Line-Interactive-UPS--12V9Ah

Yeah had a look at that thread. I know *cheap* UPS's aren't recommended however I'd be happy with 12mth use for <$200 if it met the spec, don't mind paying a bit more though if necessary.

In particular I'm interested in advice on my server system itself as I have no way of measuring actual power consumption, only going by the two PSU ratings of 750W each (redundant) so am I safe to base my calculations off up to 750W power consumption or should I allow for X overhead / efficiency?

we have a similar server at work with slightly less drives, and each power supply use about 150w so 300w's all up.

i wouldn't load the ups over 50% of its rated wattage. as it will drain that much quicker and allow you room to expand

buy a more expensive one and speed $200 every 3-5 years on batteries, works out better in the long run

I'm not sure if that's how my one works. It seems like it only uses one PSU (solid light on) and the other goes into standby (flashing light) until it detects one is offline.

I ended up going with the Blazer II 2200VA for $200 from PBTech and seems good so far. With 2yr warranty and redundant PSU to carry out tests (or even stick on another UPS) not sure how much can go wrong.
