CPS patent PSU+UPS Combination Unit
What's a ATX PC-USPS?
- It can simply be seen as a combination of an UPS and a PSU (Power Supply Unit),
but much more than that. We would rather call it a “Hybrid Power supply” because
the smart way it works if you knew that. One of the best part is it has the same
size as a standard PSU. Therefore, when installed, it can replace the original
PSU in your compatible PC or Server easily. Your PC or Server will work as the
same; the only difference now is you do not have to worry about blackouts
causing lose of critical data since the unique patented device has both a
built-in battery and backup ability, just like a Lap-top.
