Which PSU For This System?


maybe it's not the PSU then .. :( Do those numbers sorta sound right, for my rig? –Pure.Krome Jul 24 '10 at 4:00 @Pure - Over time PSUs deteriorate. More modern ATX power supplies can deliver almost all (typically 80–90%) of their total rated capacity in the form of +12V power. To prevent confusion, only modern CPUs are listed. Here's what you should know to help make that decision easier. http://hcsprogramming.com/power-supply/psu-enough-for-system.php

Modern computers use switched-mode power supplies (SMPS) with a ferrite-cored high frequency transformer. asked 6 years ago viewed 49473 times active 2 years ago Blog Women in the 2016 Stack Overflow Survey Visit Chat Linked -2 What Power Supply Unit (PSU) is needed for Another ATX addition was the +5V SB (standby) rail for providing a small amount of standby power, even when the computer was nominally "off". These power supplies were generally not capable of power saving modes such as standby or "soft off", or scheduled turn-on power controls. http://outervision.com/power-supply-calculator

Ideally, there would be one current limit per wire, but that would be prohibitively expensive. The most efficient PSUs are the ones that come with an 80 Plus rating, which is assigned by an independent certifier. Higher-quality power supplies can be over 80% efficient; as a result, energy-efficient PSUs waste less energy in heat and require less airflow to cool, resulting in quieter operation. For example, a 900-watt power supply with the 80 Plus Silver efficiency rating (which means that such a power supply is designed to be at least 85-percent efficient for loads above

For the same example, only 37% of the units (fewer than a half) are expected to last 100,000hours without failing.[a] The formula for calculating predicted reliability, R(t), is R(t) = e Cooler Master. 2008. The switched-mode supply is much lighter and less costly, and is more efficient, than an equivalent linear power supply. Cooler Master Power Supply Calculator But finding a solid, efficient power supply is possible if you arm yourself with the right knowledge.

is there any way I can see if i need a bigger PSU without having to buy one and then test that out? It is no way to be construed as a recommendation of any kind. For a description of the potential problem, a 3.3V rail may have a 10A rating by itself (7001330000000000000♠33W), and the 5V rail may have a 7001200000000000000♠20A rating (7002100000000000000♠100W) by itself, but click site Retrieved 2014-06-29. ^ "M12 Power Supply Series".

A typical PSU calculator works by calculating the power requirements from the Thermal Design Power (TDP) values from some main parts on the system. Asus Power Supply Calculator Not all PCs are built alike, so the amount of power each one needs is different. but if I continue, then it's all fine. Modern personal computers universally use switched-mode power supplies.

  1. Archived from the original (PDF) on October 21, 2014.
  2. Original IBM power supplies for the PC (model 5150), XT and AT included a line-voltage power switch that extended through the side of the computer case.
  3. Efficiency generally peaks at about 50–75% load.
  4. There's a chance that if your PSU is older, it could be 50% efficient or worse. –MDMarra Jul 24 '10 at 20:11 hmmm.
  5. In fact, you could even go two rungs higher.
  6. Low-quality power supply manufacturers sometimes take advantage of this overspecification by assigning unrealistically high power supply ratings, knowing that very few customers fully understand power supply ratings.[1] +3.3V and +5V rails[edit]
  7. Is there a word for a statement which is false but comfortable to believe in?

In all of that time I have never had PSU problems. As with any technology, you can geek out and get a lot more specific about what you want or need, but if you are a beginner, the aforementioned three aspects will matter Psu Wattage Calculator If you have an opportunity to actually hold a cheapie in your hand at the same time as a nicer model, you'll be able to tell the difference immediately. Psu Calculator Corsair Efficient power supplies also save money by wasting less power; as a result they use less electricity to power the same computer, and they emit less waste heat which results significant

Buying Guides SSDs Are About to Skyrocket in Cost: Should You Upgrade in 2017? Also, the PSU calculators are not reliable. –Sathya♦ Jul 24 '10 at 12:18 @Sathya I think it's more an indication his PSU might be failing, personally. Psu Calculator Evga

Developed by the Server System Infrastructure (SSI) forum, a group of companies including Intel, Dell, Hewlett-Packard and others, that works on server standards, the EPS form factor is a derivative of useful reference Tom's Hardware.[dead link] ^ a b "Google plans to go carbon neutral by 2008" by Bridget Botelho 2007 ^ "Ecova Plug Load Solutions" (PDF). 80plus.org. ^ "Power Supply Design Guide for

In the event of a failure, however, a single-rail power supply has the potential to shoot much more current into your components.

When the power factor correction (PFC) was required, those filter capacitors were replaced with higher-capacity ones, together with a coil installed in series to delay the inrush current. Types Of Power Supply Unit Most power supplies hit their peak efficiency levels with loads in the range of 40 to 80 percent.

All else being equal, a 500-watt power supply won't consume any less power than a 1000-watt unit. this page In some cases these are also used to provide additional power to PCI cards such as FireWire 800 cards. 4-pin Molex (Japan) Ltd power connectors (usually called Mini-connector, mini-Molex, or Berg

I know the wattage but I'm unsure about connectors. Connecting the unit configured for the lower range to a higher-voltage grid usually resulted in an immediate permanent damage. Can the Mage Slayer reaction attack be triggered by a cantrip? The fan placement can be used to efficiently exhaust air from the processor and core area of the motherboard, making possible smaller, more efficient systems using common industry components.[24] Most portable

While models will advertise this number proudly on the box, it might not tell you the full story. If the total 12V rating on the power supply is higher than the suggested rating of the card, then that power supply may fully serve the card if any other 12V Initially, this was supplied by the main +5V supply, but as power demands increased, the high currents required to supply sufficient power became problematic.
