Will a 1200VA voltage regulator cover your PC and accessories?
Will a 1200VA voltage regulator cover your PC and accessories?
Hi everyone,
I’m not an electrician or expert in electrical systems, so I want to make sure I’m doing things safely.
I recently purchased an APC 1200VA AVR voltage regulator and was wondering if the 1200VA is enough to handle all my equipment without overloading it.
I reached out to APC support but haven’t received a response.
Here’s a summary of my setup:
- PC: Intel i5 4460, GPU with 2GB RAM, micro ATX motherboard, SSD and HDD, PSU CoolerMaster MasterWatt (550W), 6 fans, USB keyboard/mouse, DAC AMP.
- Load wattage: 344W
- Recommended UPS rating: 750VA
- Recommended PSU wattage: 394W
My equipment includes two Yamaha HS 5 speakers (70W each, 45W for LF, 25W for HF) and a 24-inch Samsung LED monitor (25W).
Thank you in advance for your help.
Yes, but I suggest using the PowerChute software to switch it off after 5 minutes of power loss to conserve battery life. I wouldn't place the monitors or speakers on it, as keeping them active would waste power needed for the computer to shut down during updates or other tasks, and they don't require the same UPS protection as the main system.
1200VA should suffice since the actual power usage isn't half of what it seems. Still, it's wise to consider purchasing a Kill-A-Watt to confirm your requirements. Keep in mind that VA differs from watts; VA indicates apparent power consumption. Also, it's good to keep a monitor connected to the UPS in case you need to perform manual tasks before turning off the computer.
I explain my device as an APC Voltage Regulator, which differs from a UPS in that most UPS models also contain a Voltage Regulator. When the main power goes out, a voltage regulator stops feeding connected devices right away. In regions with unreliable mains, people often rely on Voltage Regulators to avoid low voltage "brown outs" or excessive voltage situations that could harm delicate equipment.
If your APC unit functions as a UPS, set up PowerChute Personal Edition version 3.1 on your computer and connect a USB cable from the APC UPS to your PC. Launch PowerChute, navigate to the Monitor Status area, and click on Current Status.
On the system I’m using (AMD 5600X), PowerChute displays "Your battery backup is currently providing 91 Watts of power. You can connect additional equipment to your battery backup."
When another computer linked to the same APC UPS is turned on, the power usage shown in PowerChute rises.
On a heavily loaded UPS, you might only have about 5 minutes of battery backup after the mains fails. Disconnect any non-essential devices right away and shut down the most power-hungry equipment promptly.
Thanks for the clarification. The unit I just purchased is an AVR device, not a UPS.
The AVR doesn't include a battery, so I bought it because the electricity in my home or country is unstable—there are frequent dips and spikes, and the voltage stays above 230V but isn't consistent at 220V.
I'm wondering if a 1200VA unit would be enough for my monitor, speakers, and PC.
Based on your specifications, I believe you're fine. However, I think a 1200va UPS would be more suitable. It not only stabilizes the power but also allows you to handle temporary drops or low voltage situations. A UPS could cost twice as much as what you initially purchased.
Thanks, yes the UPS cost twice as much from this AVR, which puts me over the budget. If I'm not wrong, isn't AVR also offering the same low voltage protection? The only difference is that it doesn't include a battery, so I can't save my work during power outages? Thanks, unfortunately I'm currently running short on funds (broke 😔), so I might not want to buy anything for a while.
The main goal of an AVR is to stabilize voltage fluctuations or spikes beyond what's considered normal. I recently returned from a vacation where hotel air conditioning units had heavy AVRs weighing 20kg, each rated at 4kVA. When the power supply dropped from 220V to around 100V, you might still hear the motor in the AVR moving a slider inside the Variac transformer, unless the noise from the ACU is louder. I've recorded mains voltages ranging from 55V AC to 330V AC overseas. In the higher voltage case, all the light bulbs in my hotel room exploded. These places weren't equipped with an AVR.
