How many watts do i need?
381800
Sorry, I initially posted the wrong comment to a different product question.... For my zone (3) I believe it requires 250w for a pond less than 100 gallons. 750w for a pond 100 to 750. Check with the manufacturer to be sure. Hope this helped.

It depends on where you live and how big is the area you need the heater for. My pond is 2 ft deep and measure 8 ft x 8ft wide for the winter and I live in southeastern Minnesota.

We just plugged the unit into a 110 outlet. Not sure what you need to know beyond that.

Add up the wattage you need to run your AV system and then make sure the system you buy can handle that wattage plus 30% of that total. Say your system needed 750 watts to run; then that means you would want a system that could handle 1000 watts. The same rule is used for sizing generator output needed. You never want to load a genset or battery backup more than 70% of it's max output or capacity.

Depends upon what is installed in your computer. CPU, hard drive, video card,RAM, motherboard including optical drive all need power. I would say 350 watts and above would be a safe bet.

Depends on use. Lights and Ceiling fans, 250w is fine. If you have a Electric ceiling heater That requires more watts, then the 600w I would use. Hope this helps.

Would recommend at least a 600wat psu.(Also depending on what else you have in your system)

If you are just going to make a cup or a few cups at a time you need 1500watt Transformer. If you are using it for couple of hours at a time you should consider even doubling the watts (3000w).

I don't know the exact wattage requirements for your setup (you have to take into account the number of fans. CPU cooling, number of hard drives and optical drives, etc). But an 850W PSU is almost certainly enough for your rig. You can check out some websites like: powersupplycalculator.net to double check. But I'm 99.99% sure you will have PLENTY left over with an 850W PSU.

Yes. What other components are you putting in your computer (who many video cards etc.)? Use a watts calculators (search for a free one by Asus). Thankfully, 1000 watts should handle just about anything right now.

The spec sheet says the minimum power requirement is 300 watts for the system and 65 for the card, so it would seem your system is right on the edge.

They want a 600 watt supply for one. So figure about 300 watts each card. I'd do 900 watts at the minimum.

I needs 230 watts per card. 2 of them sum up to 460 watts witch will leave a very small room for CPU RAM Motherboard and HDD. You need a PSU thats at least 1000 watts to run 2 of them I'll recommend 1200 watt so you leave room and that way your PSU runs cold. You don't want all the heat a PSU generates when near 80% of usage. Even more when shopping for a new PSU make sure that a big part of the power is in the 12v rail. In electronic Power = Voltage * Current . in this case voltage is 12 current is what your PSU says on the box (you can check this while shopping) so. Power for 12 V = 12V * 56 = 672 watts for 12 V. This is an example Going back to you PSU u have 4 rails of 12v. @ 20Amp each. If you use 2 for each card ull get Card 1: 12v@40A = 480watts card uses 460 - 95% ( danger) Card 2: 13v@40A = 480watts card uses 460 - 95% ( danger) They are too close to the limit 95% and you have no room for CPU and Motherboard. They take about 150w more. And you only (at best) only have 40. Hope this helps for more info google search PSU watts explanations or ask me again.

It depends upon how many graphics cards you mount and how many hard drives. 850 Watt should be plenty of power.

I suggest you buy a converter which supports power at least 3 times larger than what you really need, this will make you less trouble. Thus for your PS, 500W seems good enough.

thank you all for your response. I now understand what I need, at least 8 amps power supply ...enjoy your weekend!!!! :_)

I've read that you should only use a converter for up to half the rated power output, so anything up to 150 watt would be OK. So, I'd suggest you get a more powerful converter, e.g. 500 W.

well you may find you need more than 200 watt transformer. i got a 500 and run all my U.S. stuff on it. ie TV, laptop.. hard drives :)... ps stay away from the one with the usb port. its junk.....

I just read the online user manual, and watts is one of the readings you can get. See pages 9 & 10. http://www.p3international.com/manuals/p4460_manual.pdf
