Denneisk You can never have too many watts, but if you want to save power and money, tally up the minimum wattage for all your installed components and round up.

  • If you're still a bit hazy on what exactly voltage and current are, it's probably better to quit now.
  • Yes it does, there are two 6-pin+2-pin.
  • Theadditional resistance is negligible.Compare the amperage of each voltage.​​​ A PSU's wattage rating isn'tconducive to determining amperage at anyspecific voltage.

A year-old PSU is most likely not capable of producing the same amount of energy it once did when it was new. 4 Determine the robustness of the PSU.

Also, most PSUs will haveboth a 4-pin and 8-pin auxiliary 12Vconnector for motherboards, and only high-end PSUs will have one or more 6-pin PCI-E connectors for video cards.Look for PSUs with Take what a device says on its nameplate seriously and don't give it more voltage than that.

For example, if a unlabeled device was powered from a 9 V and 1 A supply, you can replace it with a 9 V and 1 or more amp supply. https://www.quora.com/What-is-the-power-supply-unit-PSU-in-a-computer-system-Is-it-only-about-SMPS-or-more-parts-of-the-CPU This information should be provided when purchasing a PSU from an online vendor and visible on the unit's retail box. solved Selling my computer for parts, taking out my HDD and SSD, questions about how I should go about this. This event is often noisy and very busy.

Electrical components all have voltages above which they fail. this contact form Devices that needed the "12 V" were designed to handle that, so that was fine. The +2-pin would clip onto the 6-pin making it 8-pin if needed. In fact thats the one I currently have myself.

Asingle-rail design isn't itself a sign of a low-quality PSU.Get a modular PSU.​​ It will helpeliminate extra wires to get in the wayof cooling. All PSUs will have a sticker with their rated amperage at each voltage level. My motherboard is Asus B85M gamer and power supply is thermaltake 750W gold. have a peek here A year-old PSU is most likely notcapable of producing the same amount ofenergy it once did when it was new.Determine the robustness of the PSU.​​How well does the PSU handlechanges in

There are various things a supply can do if you try to exceed the 1 A rating. The hub has a wireless Xbox receptor (with up to 4 xbox controllers ... PSU Ratings: +3.3V = 22A which would equate to 72.6W's +5V = 34A which would equate to 170W's +12V = 36A which would equate to 432W's -12V = 0.5A which would Check This Out Most of the time, lower voltage will just make a device not work, but damage can't be ruled out unless you know something about the device.

As that consumption is measured at the wall, multiply by the review system's power supplies efficiency to get the output. (If you don't know, 0.82 will be close or slightly pessimistic.)
