Are These Power Supplies Okay?

Our generic 500W power supply died when we tried pulling 275W from it, so the maximum amount of power we could extract was 250W– half the labeled amount! ^ "Anatomy of solved Is this power supply ok? How to select element has class start and end with specific string using jquery? However, if you want to be more cautious with it, then you could add your own highly stable voltage regulator (a great reference for this can be found at: http://www.rason.org/Projects/discreg/discreg.htm )

I think I may just play it safe and try to buy a new adapter. In older PSU designs, it was used to supply the voltage regulator, located on the low-voltage side of the transformer, allowing the regulator to measure output voltages. power-supply voltage current tutorial share|improve this question edited Sep 23 '15 at 21:13 Passerby 42.3k433113 asked Jun 28 '12 at 21:54 Olin Lathrop 210k23242554 45 I think I've seen this Modern high-powered graphics processing units do the same thing, resulting in most of the power requirement of a modern personal computer being on the +12V rail. http://www.tomshardware.com/answers/id-2614024/power-supplies.html

I want to know some opinions on them. It may be that new HDD, I just refused to swallow that fact that I could get a new with the identical weird issue, made me think something was causing it. The curve varies from model to model (examples of how this curve looks can be seen on test reports of energy efficient models found on the 80 PLUS website).

For example, genuine Dell power source uses 1-Wire protocol to send data by third wire to the laptop. The "12 V 1 A" supply might limit the current to 1.1 A, for example. share|improve this answer answered Jun 29 '12 at 15:07 stevenvh 122k12386595 The transformer in electronics.stackexchange.com/questions/34754/… says 12V(AC) and 35VA, it doesn't mention current at all. Is it within the Cantor set?

For a "12 volt 1 amp" supply, that means all is fine as long as you don't try to draw more than the rated 1 A. Minimum Load Some power supplies, generally older switchers, have a minimum load requirement. The original monitor PSU (PA-1650-68) was fixed at 19V and 3.32A. Olin explained with fruit, I'll try to explain with another flow: water.

AnandTech. 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 I did find an old laptop power supply that has these ratings: Input: 100-240VAC, 50-60HZ, 1.2A Output:19V, 3.42A There is a weird symbol between the 19V and the 3.42A, but I Thats the same 750 Ti I have.

One of the pins belongs to the PS-ON wire (it is usually green). http://electronics.stackexchange.com/questions/75036/what-is-the-dc-ok-relay-used-for-on-a-power-supply Common certificate marks for EMI/RFI are the CE mark, FCC and C-tick. I heard that little bzerrkrp sound and I knew it had crashed... Power supplies capable of delivering more than 18A at 12V connect wires in groups to two or more current sensors which will shut down the supply if excess current flows.

Unlike the standard mains electrical wire color-coding, each black wire is a ground, the red wire is +5V, and the yellow wire is +12V. The long narrow profile of the power supply fits easily into low profile systems. Each PCI Express 6-pin connector can output a maximum of 75W. 6+2 pin For the purpose of backwards compatibility, some connectors designed for use with high end PCI Express graphics cards However, a large quantity of hard drives or PCI cards will create a greater load on the +5V rail.

Most adapters and devices are DC.

electronicproducts.com. So the 380 Watt PSU would work well with the card then? Originally, a power supply featuring "multiple +12V rails" implied one able to deliver more than 20A of +12V power, and was seen as a good thing. Testing under load is recommended for the most accurate readings.[34] ATX PSU tester with an LCD ATX PSU tester with LED indicators Ripple tests are performed with an external load and
