Oops… we needed 400 and we only have 360. [I used 90 because it was easier to understand than 100 to me anyway, 90 is a little extreme overall but short-term In other words, if your computer is using 50 watts of power your 500 watt power supply would be drawing considerably less power from the wall outlet than the 1200 watt Desktop power supplies have a power output rating of from 200 watts to 1800 watts (for ultra-high-end, enthusiast-class products). Some components are powered directly by the PSU, some receive power through the board, and some are a split of the two. http://hcsprogramming.com/power-supply/what-s-the-wattage-of-my-psu.php

Five of 80 Plus's certification levels. November 28, 2012 john3347 tech27 - the efficiency factor that the author talks about would come into effect in your proposal to replace a 500 watt power supply with a 1200 Some of the responses here show a total lack of understanding. When calculating the amps for the +12V line, it is necessary to look at the total amps produces from all of the 12V rails.

Indeed, the abundance of PSU-related misinformation and deception in the marketplace would be comical if it weren’t so harmful to consumers.

November 28, 2012 sorinc @tech27 -- having a larger PSU than necessary would make it run inefficiently, i.e.

  • This is what we typically see when looking at PSU specifications on a retail website, like Amazon or Newegg.
  • It can also be used to calculate the cost of electricity as well as optimize the parts for energy efficiency or low noise levels.

  • Other specifications and features are important, too, but these three directly affect the PSU’s performance.
  • What is the difference?
  • Depending on the device, this sometimes makes assumptions of other system components – if it's a higher-end GPU, the minimum PSU spec may be assuming higher-end accompanying components, which will draw

draw more power from the socket than necessary. The voltage supply down the 12v rail, for instance, won't read-out as exactly 12v when considering the PSU's switching behavior.

Clearly, you should aim to have your PSU sized appropriately for your system-putting a high-load PSU into a basic desktop machine doesn't increase your safety margin and decreases your efficiency costing Power Supply Calculator Newegg It all depends on the build, of course, and that's what we're dissecting here. Many users choose a power supply based on total wattage alone, assuming that higher is always synonymous with better.  Others pay no attention to their PSU selection at all, and settle This Site A glimpse inside a PSU.

Meanwhile, modular cabling greatly simplifies keeping the interior of your case nice and clean—just don't connect any superfluous cables to keep the clutter down. Asus Power Supply Calculator For this article, we deployed a high-end, 89-94% efficient Enermax Platimax PSU with 80 Plus Platinum certification and 1350W of power. Version history February 4th, 2014 First version released February 13th, 2014 Added over 100 hard disks and SSD drives. Modern CPUs and GPUs use dynamic voltage to mitigate power draw during idle or low-load times, as seen in Intel's S0iX (“Active Idle”), which throttles clockrate in-step with voltage reduction –

November 28, 2012 Salvatore Hidalgiano How this information is gonna help me when buying a new PC ? Thank you for signing up. Nevertheless, various indicators provide circumstantial evidence of PSU quality, and some guidelines are generally helpful. Source In many cases, that's not the actual power.

The greater topic of PSU selection – that is, regarding topics beyond wattage – is out-of-scope for this content, but it's worth going over a few basics. Bitcoin Mining Modules I still don't understand the whole thing… Does buying a high-load PSU that surpass the actual wattage on your system causes problem on your system? Exhaustive PSU Usage Benchmarks By Steve Burke Published November 30, 2015at10:13 pm Hardware Guides How Many Watts Does a Gaming PC Really Need?

You can look at resistance like this.

I ran it through a wattmeter, and average use when active was only about 100 watts. Each manufacturer and PSU supplier will have its own efficiency curve that fits the specs of the power supply, but a good, general assumption is that 50-60% load (demand for power) Let's say power surges take the voltage down to 90v from 120v. Watts-up-pro Es Avoid cheap, generic power supplies, which tend to be substandard.

Here's a table of 80 Plus Certified ratings: Efficiency at Rated Load: 115v (230v) 80 Plus Certification 10% 20% 50% 100% 80 Plus -- 80% (82%) 80% (85%) 80% (82%) 80 http://hcsprogramming.com/power-supply/will-a-higher-wattage-power-supply-really-hurt.php This may be only a small fraction of say the 450W the power supply is rated at.

The main power connections in a system operate on rails of three voltages – 3.3v, 5v, and 12v – and are used to drive devices of differing power requirements. Let's say your system needs 400 watts out of your 480w power supply. But that's OK, because modern power supplies will draw only as much as required to drive the system. The OCP on single-rail units kicks in only at much higher amperages, which could lead to a major melt-down if a serious overload occurs.

For optimal viewing, please lower your browser's text size setting. Look for reputable brands that offer solid warranties and support. 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 If this is not done properly, the irregular power signals that are sent to the components can cause damage and system instability.

Let's talk tests. If you have specific power hungry components, check the power supply requirements with the manufacturer. Change Vcore to adjust core voltage from stock value. Most GPUs and some CPUs will recommend a minimum wattage for operation.
