Whether 700 watts is considered a lot of electricity depends on the application and the context. Watts are a measure of power, and 1000 watts equal one kilowatt (kW). A kilowatt-hour (kWh) is a measure of energy consumption, calculated by multiplying the number of kilowatts used by the number of hours of usage. For example, a 1000-watt device operating for one hour consumes one kWh of energy. The average American home consumes 909 kWh of electricity per month, with heating and cooling accounting for nearly half of residential electricity consumption. In the context of solar panels, 700 watts may not provide significant economic benefits for a $300/mt customer in Southern Florida. However, in the context of a PC with a 700-watt power supply unit (PSU), the power consumption may vary depending on the efficiency rating and the number of components in use.
| Characteristics | Values |
|---|---|
| Watt as a unit of power | 1,000 watts = 1 kilowatt (kW) |
| Kilowatt-hour (kWh) | A measure of energy consumption, calculated by multiplying the number of kilowatts used by the number of hours |
| Average Electricity Consumption (US, 2013) | 10,908 kWh per year or about 909 kWh per month |
| 700 Watts of Solar Panels | May not provide economic benefits in certain locations, such as South Florida |
| PC Power Consumption | A PC with a 700W PSU may use around 200 watts at idle and up to 450 watts under load, excluding the LCD monitor |
| Reducing Electricity Consumption | Heating and cooling systems, older lightbulbs, and plugged-in appliances contribute significantly to electricity usage |

What You'll Learn
700 watts of solar panels
700 watts is indeed a lot of electricity, and 700-watt solar panels do exist. However, they are quite large, almost 94 inches long and 51.3 inches wide. They are also not very efficient, with a maximum efficiency of 22-24%. This means that a 700W panel is double the physical size of a 350W panel of the same efficiency.
If you are looking to increase your total power output, a 700W panel will achieve that as it will produce more power in low-light conditions. However, you may experience clipping with existing micros, especially during the middle of the day when solar input is at its peak.
To utilise 700W panels, you will need to upgrade your system, as they will not work with a 300W inverter. A bigger system will also be required to accommodate the larger physical size of the panels.
If you are looking to cut your energy bill in half with solar panels, you would need to calculate how much energy you use per day and then determine how many panels you would need to meet that demand. For example, if you use 38kWh per day, you would need approximately 4.75 kW per hour or 4750 Watts per hour. This would mean using about 20 250-watt panels.
In conclusion, while 700-watt solar panels do exist and can increase your total power output, they are large and inefficient and may require system upgrades. To determine if they are suitable for your needs, you should consider your energy usage and the space you have available.

700W power supply unit (PSU)
700 watts is indeed a lot of power, and a 700W power supply unit (PSU) is a mid-tier power supply that can be used for a PC build. Modern PSUs will use only as many watts as the components in the PC require, plus around 20% extra depending on their efficiency rating. For example, a PC with a 700W PSU might use around 200 watts at idle and 450 watts under a full CPU and GPU load. This means that a PC with a 700W PSU will not always be consuming 700 watts of electricity.
When considering a 700W PSU, it is important to take into account the wattage capacity, form factor, connector support, efficiency ratings, and modularity. For example, a larger ATX PSU will take up more space than the more compact SFX technology. Additionally, checking the PCIE and EPS connector compatibility is crucial to ensure the PSU will work with the specific PC configuration.
Efficiency ratings, such as the 80 Plus certification, indicate the energy efficiency of the PSU. A higher efficiency rating means less power is lost during the conversion of AC to DC power, resulting in potential energy cost savings. Modularity is also an important consideration, as it allows for greater flexibility in cable management and future upgrades.
While a 700W PSU can provide sufficient power for a gaming PC or a high-performance computer, it is important to consider the specific components and their power requirements. A PSU with higher wattage capacity can future-proof the system, allowing for potential upgrades or the addition of more power-demanding components.
In terms of electricity consumption, a PC with a 700W PSU may consume around 250 watts most of the time it is running. This means that it would need to run for 4 hours to consume 1 kilowatt-hour (kWh) of electricity. The actual electricity cost will depend on the local electricity rates and the efficiency of the PSU.

700W appliances
Whether 700 watts is a lot of electricity depends on the appliance and how long it is being used for. For example, an electric blanket may be used for 2 hours, whereas a hairdryer is typically used for 5 minutes. So, while the hairdryer uses more power in a shorter amount of time, the electric blanket uses less power over a longer period.
A 700-watt appliance could be a microwave oven. Microwaves with wattage between 600 and 799 watts are available on the market, with some brands offering models within this range including Panasonic, Sharp, Insignia, Bosch, Costway, and KitchenAid.
A PC with a 700-watt power supply unit (PSU) may only use around 200 watts at idle and up to 450 watts under a full CPU and GPU load. The actual power consumption of a PC with a 700-watt PSU will depend on its components and efficiency rating.
To estimate the electricity cost of running a 700-watt appliance, you can consider the power consumption in watts and the duration of usage. A 'Killowatt Hour' (kWh) is the amount of power a 1,000-watt device would use in one hour. So, a 700-watt device running for one hour would consume 0.7 kWh.

700W electricity bills
700 watts is a significant amount of electricity, and the impact of such usage on your electricity bill will depend on how often you use an appliance that consumes this much power.
To calculate the cost of running an appliance, you need to know the power draw in watts, your electricity tariff in cents per kilowatt-hour (kWh), and an estimate of how often you use the appliance. Kilowatt-hours are a unit of energy and are used to measure electricity consumption because they are a larger unit than watt-hours. One kilowatt-hour is equal to the energy used to maintain one kilowatt (or 1000 watts) of power for one hour.
For example, let's say you have a PC with a 700W power supply unit (PSU). The PC won't automatically use 700W just because of the PSU; it will use however many watts the components in the PC need, plus around 20% extra depending on the efficiency rating. So, if your PC uses around 250W most of the time it's running, it would need to run for four hours to consume 1kWh of electricity.
If you live somewhere with relatively expensive electricity, like Texas, running a 700W appliance for long periods could significantly impact your bill. However, if you only use the appliance for a few hours a day, the cost will be lower.
To reduce your electricity bill, you can try to conserve energy. This might include actions such as turning off lights or appliances that aren't in use, using more clothing and less heating, hand-drying dishes instead of using a dishwasher, and replacing old incandescent light bulbs with more efficient LED bulbs. You can also try to improve the insulation in your home to reduce heating and cooling costs.

Frequently asked questions
Whether 700 watts is considered a lot of electricity depends on the appliance and the context. For example, a modern PC with a 700W power supply unit (PSU) may pull around 400W from the wall, with an additional 100W for an LCD monitor.
A 700W solar panel system in South Florida may produce about $5/mt worth of energy. However, the amount of energy produced will depend on various factors, such as local requirements, mounting options, and system efficiency.
According to the US Energy Information Administration (EIA), the average American home used 10,908 kilowatt-hours (kWh) of electricity per year in 2013, which equates to about 909 kWh per month.
To reduce electricity consumption, consider the following:
- Start with your Heating, Ventilation, and Air Conditioning (HVAC) system, as it accounts for nearly half of residential electric consumption. Improve insulation, install ceiling fans, and set energy-efficient temperatures.
- Unplug infrequently used appliances and reduce "phantom load" electricity consumption by using power strips.
- Consult a professional electrician for tailored recommendations.
