The difference between the power supply?

Dilemma caused by Bonian: Difference between power supply.?

I am looking for a new power supply for my PC, but I have no experience with them. So I went on youtube for a crash course, didnt help. Basically, i am confused as to why one of these power supplies is way more expensive but hass less wattage: http://www.newegg.com/Product/Product.aspx?Item=N82E16817152036

The price difference comes from the ” 80plus ” certification. that means that it is at least 80% electrically efficient and thus usually constructed of better components. personally, ive never heard of raidmax so i would go with the OCZ or Corsair.

hope that helps.

Kinda depends what you are using it for, but I think I can help you out.

The first one is the “economy” class PSU. It has a high wattage rating so you can use it for pretty much everything in your computer, even with a high-end graphics card. However, the efficiency is only “up to 85%” meaning that at high heat and usage, it’ll become less efficient and suck up a lot of electricity. Comes with a 2 year warranty.

The second one is like an upgrade of the first. It features a 3 year warranty instead of 2 year, has an 8-pin power connector in addition to all the connectors that the first one has. It also has a higher efficiency rating, meaning your electric bill will be (slightly) lower. It has the ability to put out more amps, which means more power, and is SLI certified if you ever want to use multiple high-end graphics cards. It’s also (very slightly) smaller than the first PSU.

The third one is the “premium” power supply. It’s about the same size as the second one, but is rated for 650W instead of 600W. The fan is probably quieter than the other two, and it can put out the most power in Amps. It also has a 5 year warranty. The most notable things about this one is it has 2 PCI express adapters, and 8 SATA connectors, meaning you could potentially power two separate computers that have high-end graphics cards at the same time with just this one PSU. It’s also marketed as “compatible with Core i7″ although I’m not entirely sure what they mean by this. Core i7 is Intel’s new super-high-end processor bundle, so it might have special power requirements or something.

I would recommend buying either the first or the second PSU, unless you really need the third one.

Ignore what the Box says… There’s only one way to actually calculate wattage output.

Volts X Amps = Watts

Look at how many amps are supplied on the +12v rails.

40amps X +12v = 480

The main parts of the system such as the processor and graphics card use the +12v rail. Processor usually use 100-150 watts. Graphics cards vary. Lowend cards use under 100w, Midrange cards use around 150w, and the ultra high end cards use 300w and over. Other parts may use between 50-100w.

these are peak levels. It’s rare that anything would hit the peak. Cheap power supply can never put out what they claim.

80plus means efficiency. The Higher the certification the less power that gets wasted.

Have any idea a lot better?
