Solved: Need Info On Power Supply

They told me that my lifetime warranty was expired, as I had never registered the product (That's really neither here nor there, but may be useful information to those of you I'm not an advanced hardware technician, but I always thought that a multi-meter would read the power supply in the same way that a specifically designed tester would. This book, although not a proceedings, has resulted from his work for the conference. It collects contributions on materials for information technology applications from the author’s of conference papers as well as As with plugging a 24 pin cable into a 20 pin motherboard connector, you can plug an 8 pin cable into a 4 pin connector and leave 4 pins hanging over Check This Out

The 12V CPU power cables CPUs used to be powered by the 20 pin main power cable. If your power supply main power cable and motherboard main power connector both have the same number of pins then they'll (of course) fit together just fine. This subject of multiple 12 volt rails is more complicated then you may think. I'm not even positive if this tester works, as I've got nothing else to test with it for a baseline, right at the moment. imp source

Older power supplies provided the bulk of their wattage on the 3.3/5 volt rail and new supplies deliver it on the 12 volt rail. You can get adapters which will convert various kinds of power supply cables into both 4 pin and 8 pin 12V cables. The 24 pin cable is just the 20 pin cable with 4 extra wires added to the end to provide extra current. They did tell me that the power supply could be fine and it may be just receiving an incorrect signal from the motherboard.

As a result, you need to be careful when plugging an old power supply into a new computer or a new supply into an old computer. Since the Athlon 64 and Pentium 4, computers have consumed most of their power from the 12 volt rail. This page introduces you to the issues you need to consider to maximize the chance that an ATX power supply and motherboard will work together properly.

I peruse this site from time to time to troubleshoot and find answers to various problems I've had. This, by my understanding is the standby power voltage. The 4 pin cable is often called a P4 cable (although it's a very bad name) and the 8 pin cable is called an EPS12V cable. Dr Caroline Whelan is a researcher at the Interuniversity MicroElectronics Center (IMEC) Leuven, Belgium, a leading research institution in microelectronics funded by industry, government, ESA and the EU.

The system may become unstable or may not boot up if the power is inadequate. • If you are uncertain about the minimum power supply requirement for your system, refer to Might be broken and does not contact when pushed. It will work fine if it fits. All about the various PC power supply cables and connectors Rail complications #1 - current limit problems: too much current Rail complications #2 - cross loading problems: unbalanced current Rail complications

Your test seems to indicate it is NOT the power supply as much as you might like to will it to be. Some older AMD dual CPU motherboards have them.

Advanced Microdevices (AMD) is a global manufacturer of microprocessors and other integrated circuit-based products. his comment is here Even if the connectors do match you can still run into trouble even though the power supply appears to have sufficient wattage. The compatibility rules between 4 and 8 pin connectors have a lot in common with the rules for 20 and 24 pin connectors. If you had an ATX power supply and an ATX motherboard then you plugged them together and they worked.

This is something I had never heard of before. So, in any case, I ordered a power supply tester from Hong Kong and tested the power supply. I was able to find another PSU in a box of a stuff in the basement. Thanks in advance.

Thank you very much for your responses, Lighthouse and Xhi. KG in Dresden, Germany. If you're buying a new power supply then the safest choice for the long haul is to get one with a 4+4 power cable because it's compatible with both 4 and

Almost all current motherboards power their CPU with a 12 volt CPU power cable.

Those extra 4 pins provide more current carrying capacity. Nowadays things are a bit more complicated. Older machines used to consume most of their power from the 3.3/5 volt rail. But, of course, needing to drop a bunch of money into a new motherboard would be worse.

Use this trick, and test again, Reports: · Posted 3 years ago Top Xhi Posts: 6298 This post has been reported. Now you can get an ATX power supply and ATX motherboard and end up with connectors which don't match. The HDD, SATA and other connectors don't register anything. navigate here Hi forum, First of all, I just want to say thanks to all of the active forum community members for your helpful insight and contributions.

Those are the best supplies because they provide enough wattage for all kinds of machines. The proceedings can be a valuable reference work for researchers and graduate students working in rail transportation, electrical engineering and information technologies. When I flip the power switch, the fan in the power supply does not spin. aspx?SLanguage=en-us for details. • The ATX 12 V Specification 2.0-compliant (500W) PSU has been tested to support the motherboard power requirements with the following configuration: CPU: AMD FX-62 Memory 1024 MB
