Power Supply Question. How Many Watts Do You Need?

Example : CPU = 60 watts NvidiaGPU = 200 watts Motherboard = 50 watts Etc... So a microwave oven that boasts 600 watts on the box, will have an input requirement of 1200 watts on the boilerplate in the back.

If you have a 500 Watt Power Supply but then a super-low-consumption PC that only consumes 80 Watt, you're not going to reach 80% efficiency and could easily use ~120 Watt have a peek here

A couple major items to consider, in no particular order: Wattage Cable management / modularity Cable options – do you have all the PCI-e headers you need? Are you looking for the solution to your computer problem? Naudé Apr 24 '13 at 14:10 add a comment| up vote 8 down vote No it doesn't. On the other hand, a sine wave is expensive to make in an inverter, and many sine wave techniques use heavy, inefficient transformers.

Repair Units and Accessories: No, you don’t need a wattage tester or guides on how to fix a PSU.

Even if you don’t care about the planet, an efficient PSU will still save you big bucks on your energy bill. RAM or a motherboard is a perfect example. What is the correct word to refer to a company's home area? This list isn't definitive and doesn't represent the “best” power supply in each price range, but provides a launching point with a wide selection of quality PSUs.

  1. See How can I ask better questions on Server Fault?
  2. A lot of smart people have worked for 100 years to develop rules which will keep you out of trouble if followed.
  3. You need to go with good quality PSU's E.g Antec, Corsair etc...
  4. In simple buyer terms, look for continuous wattage ratings, ignore peak wattage ratings, and ignore a product that doesn’t advertise its continuous wattage rating.
  5. Here's a sample power efficiency curve: In this curve – which exaggerates the delta by having only an 8-point range – we see 87% efficiency in worst case scenarios (115v) and
  6. Laser printers use up a surprising amount of power (due to the heated fusing rollers), and will discharge your battery faster than you expect, even on standby.
  7. Voltage Ripple Voltage ripple is a measurement of voltage fluctuation down the PSU's various rails, something we wrote about in-depth previously.

But you need to know what to look for. Visit Website Read More for DIY projects. The best way to know without error would be to measure the actual consumption of the running hardware, and multiply this by a factor of 2 or 3. It is quite a beefy CPU for such a low tier graphics card.

In fact, you could even go two rungs higher. navigate here You can usually check which it is on the model’s specifications page. share|improve this answer answered May 4 '09 at 19:36 Nathan DeWitt 7492810 2 ...thereby proving that a power supply doesn't constantly draw its max load. You’ll find buyers for your old one on Craigslist and Ebay.

If your system requires 600watts than choose a PSU of 650watts. bistro, Dec 30, 2005 #4 brite750 Joined: Mar 16, 2002 Messages: 13,404 thats a lot of stuff, the Asus site stinks, cant see how many fans, what size, etc. Media Streamer, Media Player or HTPC: Which One Is For You? Check This Out It all depends on the build, of course, and that's what we're dissecting here.

If your system requires 600watts than choose a PSU of 650watts. Well, like we said at the start, your PSU affects every part in your computer system and can end up frying circuits in the case of a power fluctuation. In effect, everything going into the “back” of the PSU is AC, and everything coming out the front (where the PC's power cables connect) is DC, split into various voltages as

True Power Most systems that include a Nvidia / AMD gpu wont require PSU that is stronger than 750w Also when you choose an PSU be sure that you choose one

Ditto MysticEyes on that sound card. Read More . 6. Share them with us down below, too! Inverters must be grounded properly, and treated with respect, since they put out potentially lethal voltage.

What is the 80 PLUS specification? Similar Threads - Power supply question Blown power supply in grandpas computer please help!!! Not all PCs are built alike, so the amount of power each one needs is different. http://macland.net/power-supply/power-supply-5v-question.php Even in 80 Plus PSUs, there are different levels: 80 Plus, 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold, 80 Plus Platinum, 80 Plus Titanium. (These are ordered from worst to best.)

That’s not to say that you need an expensive PSU. The 7770 draws power from the motherboard, too. This makes the entire system more efficient, and since high current transistors are expensive, the inverter will be cheaper.Q: Should I use aluminum wire, or must I use copper?A: Aluminum is Why is x**4.0 faster than x**4?

Let's look at something more realistic: 70W demand / 0.9 efficiency = 77.78W draw 70W demand / 0.88 efficiency = 79.55W draw Difference: 1.77W Assumed 24-hour uptime & assume 11.63 cents The 80 PLUS performance specification requires multi-output power supplies in computers and servers to be 80% or greater energy efficient at 20%, 50% and 100% of rated load with a true http://www.jscustompcs.com/power_supply/Power_Supply_Calculator.php?cmd=INTEL pugmug, Dec 30, 2005 #2 MysticEyes Banned Joined: Mar 30, 2002 Messages: 4,825 Seems like you might need more.
