Watt Power

Can a GeForce 9800 GT run on a computer with a 375 watt power supply?

The Nvidia website says that the maximum graphics card power is 105 watts. But, the minimum system power requirement is 400 watts. If the other components on my computer doesn’t use a lot of power, will I be able to use the graphics card?

The quick answer is Yes. The long answer is: Yes, but the reason they give you a “Recommended” requirement is because there is no exact power requirement that you need to meet or exceed to keep your card running. You could have a 400W supply, and the card will run, but you are straining your supply to run all your computer’s equipment, even if they are low power. You are essentially flirting with burning out your power supply and possibly damaging your motherboard also. Its like having a car with a 100 hp motor. Can you pull a trailer with it? Sure you can, but you are risking burning out the transmission each mile you continue on. The best solution is to get a stronger motor (a bigger power supply).

To get an idea of how close you are getting to exceeding your PS’s rating, go to an online power calculator like:

And don’t forget, unless you have a name brand power supply, you can never trust that you are getting the full power rating. Many big companies like Dell, HP, Emachines, etc, use notoriously underpowered and generic power supplies.

With our current economic melt and volatile energy prices daily, many of us are thinking about installing solar panels to contribute to the needs of our homes' energy, and reduce our electricity bills.

But how much watts of solar panels have to say reduce half energy bills? And how much power it is hard to install?

Here are four step process you can follow to respond these two fundamental questions:

1 – Calculate the daily energy used:

To do this, get your last 12 months electricity bills and calculate the average kilowatt hour (kWh) usage per month. The reason we use 12 is because our energy consumption varies with the seasons. But if you do not have all its power bills, then simply use one last month.

Then divide your monthly use by 30 (the average number of days in a month to get your daily energy use.

– For example: If you have a monthly consumption of 800 kWh, then the daily amount is 800/30 = 26.7 kWh per day.

– Now if you just want to halve your energy bill then you need to produce 26.7 / 2 = 13.4 kWh watt solar panel per day.

2 – calculate the total solar Watt Needs:

To do this, you first need to determine how many hours of their usable area receives sunlight per day. This is where a solar insolation map comes in handy – you can see one of our original article on our website.

Once you know your hours of sunlight per day, return to their necessary daily kilowatt hours and divide by the hours of sunlight daily, and then multiply by a factor of 1.25 (note into account energy losses of the cables watt solar panel, battery, and inverter)

– Continuing our example: Our watts of panels plots the same requirements:

13.4 kWh / 5.5hrs x 1.25 = 3,045 kW or 3045 watts per day.

This means we need solar panels capable to produce at least 3045 W of power.

3 - Calculate costs Watt Solar Panel:

This step will help you calculate the cost of the panels land required to 3045 Watts of power. So far the highest average cost of solar panels in the U.S. is $ 4.85 per watt.

– In our Example: It will cost us at most 3045 x 4.85 = $ 14,768 to install solar panels to halve our energy bill. And that's before wiring, controllers load, batteries, inverters, and electrical costs.

4 – Compensation Tax Credits and Refunds:

Before the facts and I think it will cost at least $ 14,768 watts to 3045 watts solar panel, it should be tax incentives and rebates in your account.

With the new renewable energy tax credits that come into effect on 1 January 2009, and the state side rebates from states like New York, Connecticut, New Jersey or California, our solar installation costs will be much lower than expected.

– Let's use our example, California If we receive tax rebate about 20% of the cost, and a 40% tax credit on the rest. So after discounts and credits, our solar panels would cost:

$ 14,768 – $ 14,768 x (20%) – $ 14,768 x (1 to 20%) x 40% => $ 7089.

Since there are many factors that go into calculating the costs of watts solar panel, please use our steps only as a rough estimate. Some things are impossible for us to consider, such as offers business special solar energy installation, which offers discounts on the full installation (including charge controller, inverter, battery, network electrician tie costs, etc.).

Anyway, what we can see that cost about $ 7,089 to buy enough solar panels to reduce half our energy bill. We, however, either get the solar cells at cost or free source, and wire our own solar panels, obviously saved us a lot of money. The good news is that anyone can learn to find inexpensive solar cells and make your own solar panel watt.
