I'm looking to step up to a UPS for my gaming rig and home server. Specs for the two:

Gaming Rig
---------------
-Corsair HX1000
-Core i7 920
-Asus P6T
-2x EVGA GTX 260 55nm
-6GB DDR3 1600
-147GB SAS 15k HDD
-2x1TB 7200rpm SATAII HDDs
-SATA DVD RW
-2x 12v Pump
-Lots o Fans


Server
---------------
-GIGABYTE GA-MA74GM-S2
-AMD Athlon 64 X2 5050e 2.6GHz
-PC Power & Cooling S75QB 750W
-4GB DDR2 800
-8x1TB WD10EADS HDDs
-640GB WD6400AACS HDD
-2x 3x5.25" - 4x3.5" SATA Raid Cages (these run 4 drives off 2 sata power cables)
-3ware 9650SE-16ML
(Will be expanded to 16 of the WD10EADS and 4x cages over time)

Other Equipment
----------------------------
-Airport Extreme
-Cable Modem w/VoiP
-10/100/1000 8 port switch

I'm looking for a UPS that could keep both machines running for a minimum of 10-15 minutes so that I can make sure any file transfers, etc are stopped or completed before they lose power (don't want to lose data due to power outages :( ).

Any recommendations on specific UPS's, or at least how many VA should I be looking at?
 
That's a lot of stuff to power off of one UPS. What video cards are you using?

Since your priority is run time, I wouldn't depend too much on VA rating to tell you battery capacity since that just tells you how much power the UPS can support; not battery capacity (though generally speaking higher is better).

Instead, you can try to find the voltage and amp-hours or watt-hours of the UPS batteries. If you know the power consumption of all your equipment (a Kill-a-watt tool is useful here), then you can do a crude approximation of your run time. However, keep in mind that battery life will diminish as the battery gets older so you'll probably want to factor in more battery life than you need.

I'd probably go for a 1500VA UPS in your case. If you go larger than that then you'd probably have to spend a lot of money on a server UPS that requires 5-20R electrical outlets. I don't know many homes that have those.

Second one there requires the special plug though.

The biggest UPS you can get that runs off a normal plug is going to be around 1500va or less. Which means a little less than 1000w of capacity in most cases.

It would be much cheaper to just get too smaller units.

It's not that special just a NEMA 5-20P.

True, but most homes will not have them and will need to have one put it (not a huge deal for some, but a deal breaker for others).

My current home was built in 1986 and has 5-20P on all the circuits that are 20A, it really isn't that uncommon a connector.
 
Sorry, forgot the vid cards. Its 2xEVGA GTX 260 55nm. I'm currently renting, so I can't install different outlets unfortunately. I guess I'll start looking for two smaller UPS's. Thanks :)
 
Funny, around here I have not usually come across them at all except for in offices and in utility rooms in houses.

But in any event, it is very easy to put one in.
 
So, I ended up with an APC 1500VA ups w/LCD and a CyberPower UPS that looks like a very large surge protector. The APC will house both machines, while the CyberPower will have all my networking gear and monitors. So far it looks like it will work well and have overhead for power expansion :)
