Is CMPSU-1000HX Compatible with UPS?

I have an TrippLite OMNIVS1500XL. Are there any issues that I should know about using it with the CMPSU-1000HX PSU?

No, why would there be?

Only thing I can think of is that if a UPS doesn't give true sin wave output (e.g. cheap quality), some PSUs may buzz a bit due to that, but that's it.

Just to clarify on the "buzz" mentioned above, it should only occur when the UPS has lost a/c power and is running on battery only. Furthermore a non-sine wave UPS does not necessarily indicate a cheap quality UPS. IMO there is no reason to invest in a pure sine wave UPS for your average "home" computer, and Corsair reps have stated that there are no ill effects of running off the battery (for a short time mind you) of a stepped/simulated sine wave UPS.

Should you be considering a UPS then I would recommend a line-interactive model at a bare minimum since they add some degree of voltage regulation. The off-line UPS is a low-cost product that protects primarily against a power outage. It is not a complete power protection solution. You can read more about them here.

Changed EliteKiller's link from a search (which isn't cached forever) to a direct thread link. You can also search for "sinewave" for more info.

Some PSUs require a "pure sine wave" and this TrippLite doesn't provide that when running off of battery. I believe the Enermax 1K Power supply's user manual says that if a UPS is used it must be a pure sine wave. I could not find any discussion of Corsair's compatibility.
