Here's a Sine Wave & CP1500PFCLCD FAQ
- True sine wave Vs. simulated/stepped sine wave
: a true sine wave has smooth flowing curves. A simulated sine wave is stepped, meaning that it has sharp edges. You can see a visual here
- Why do you need true sine wave for computers?
You only need true sine wave if you have a power supply that requires it.
- How do you know if you need true sine wave?
If you built your computer, it may require it because the better high efficiency power supplies (read more expensive) have PFC - Power Factor Correction. If you bought your PC built or from a name brand you may not need true sine wave.
- What happens if you don't have true sine wave and your PC requires it?
You'll lose power to your PC when the UPS switches to battery backup.
- How many watts do you need?
That really depends on your unique setup. The unit has a built-in kill-a-watt meter of sorts. As you plug things in and fire them up, it'll tell you the load %, how many watts you're using, and an estimate of how much time is left on battery power only among other things. The manual states "Do not exceed 80% of the unit's capacity."
- Don't measure the highest amount of time possible available (by adding how many watts you need) - there are many factors that change quickly that can drain your UPS. Always leave some head room - get a larger capacity battery than you think you need.
- That being said, I am using this particular model to backup my FreeBSD NAS running a total of 2 USB OS drives on an intel i3 7100T processor (draws little power) with 32GB RAM and 3 western digital RED NAS HDDs (and two aux backup HDDs). The usage rates are as follows: Startup peak: 50 Watts. Idle peak:31-45 Watts. As you can see this is well within range of the capability of this unit. But I built this server to use very little power in mind and choose my components around that. I also have my main i7 workstation that requires much more: Startup Peak: 115 watts, Idle peak 65-131 Watts (this includes a large monitor). Both systems run FSP Group AURUM 92+ 550W power supplies. Here's some relevant info:
AURUM 92+ Series is built with the FSP MIA IC technology which advances Active-Clamp Topology to a whole new level. With 80PLUS platinum certified and yet provides ultimate performance and highest protection that today's cutting-edge PC components demand.
Complies with ATX 12V 2.3& EPS 12V 2.92 Version
Meets 80 PLUS® Platinum Certification
Multiple+12V Rail Design
Multiple Safety Approval
Complete Protections: OCP, OVP, SCP, OPP, UVP
Quiet, Long- lasting 120mm FDB Fan
Industrial Grade Component: Japanese Capacitor
Multiple 6+2 pin PCI-Express VGA Card Connector
- With both the NAS and workstation plugged in, I'm looking at a 12% load and an estimated run time of 63 minutes. This unit will give me plenty of time to safely shutdown both of my machines.
- Although this unit would work as a power source for park VR usage, you might be better served by a small power generator.
- The manual states "DO NOT USE FOR MEDICAL OR LIFE SUPPORT EQUIPMENT,"
Do not use with or near aquariums, do not use on any transportation, do not plug a laser printer, paper shredder, copier, space heater, vacuum, sump pump or other large electrical devices into the 'Battery and Surge Protected Outlets.'"
- Price From amazon on 11/27/2017 it came out to a total of $131.35. From B&H if you live outside of the taxable states it should be $119.99
