Are These Power Supplies Okay?

The ATX connector provides multiple wires and power connections for the 3.3V supply, because it is most sensitive to voltage drop in the supply connections. Why is writing your own encryption discouraged? The two rails involved are labeled on the power supply with a combined amperage limit. It could simply blow a fuse.

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. If a power supply is used to operate the control-voltage side of things, a "DC OK" output may be used to disconnect the high-power supply except when the proper control voltage I've tried basic troubleshoot, as well as replacing the HD completely and Flashing the BIOS. In ATX-style systems, the front-panel power switch provides only a control signal to the power supply and does not switch the mains AC voltage. http://www.tomshardware.com/answers/id-2614024/power-supplies.html

I guess I'll just have to save up and replace both the motherboard and the PSU and see if that helps. or would it potentially just fry immediately. The one that gets power from the slot. In this case, 90W/24V = 3.75A, so you should be good to go with the output set at 19V with this amount of current.

I can ask for anything as long as it isn't more than the 10 liter per minute. God I hope this reveals something, I'm going crazy here lol Vic 40Nov 28, 2014, 8:14 PM You're welcome.:DHope it gives some more info.

They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot. However, some devices might appear to operate correctly, then fail in unexpected ways under just the right circumstances. Modern computers use switched-mode power supplies (SMPS) with a ferrite-cored high frequency transformer. http://www.tomshardware.com/answers/id-2394682/voltages-power-supply.html Regulated versus Unregulated Unregulated Very basic DC power supplies, called unregulated, just step down the input AC (generally the DC you want is at a much lower voltage than the wall

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. Even though my PSU voltage reads were perfect, and the log test shows no weird PSU changes before it crashes.

The long narrow profile of the power supply fits easily into low profile systems. How old is the PC? This connector supplies power at three different voltages: +3.3, +5, and +12V. 6-pin Most modern computer power supplies include six-pin connectors that are generally used for PCI Express graphics cards, but RoccoMartinelloAug 27, 2015, 11:20 AM Hi guys!!!Considering these voltages measured with a software, can we say that my PSU is faulty? (My computer randomly freezes)In my BIOS menu there aren't voltage

Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count). This PSU is rated 90W max and supports 15-24V output voltage. This connector is the largest of all the connectors. Are Americans more likely to be killed by vending machines than terrorist refugees?

This is the simple design of a passive PFC. That PSU looks like it was meant to blow it out of the top of the case. Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the You must make sure it matches what the device expects.

I wonder if the wording might not be clear to the kind of person who needs to ask this kind of question. –Rocketmagnet Jun 28 '12 at 23:53 5 Wording Who am I??? I know it is solved Is this Power Supply ok?

Theoretically endless loop terminates, unless System.out.println is used A characterization of distinguished triangles in triangulated categories.

Now, doing the math: 90W / 19V = 4.74A Of course this is an ideal value, what is "safety margin" i should assume for the real max amperage? Thats the same 750 Ti I have. Google's server power supplies are more than 90% efficient.[19] HP's server power supplies have reached 94% efficiency.[20] Standard PSUs sold for server workstations have around 90% efficiency, as of 2010. If my faucet can fill a bucket in a minute that's its maximum flow, or current.

To reduce the power losses in the 5V supply, with the introduction of the Pentium 4 microprocessor, Intel changed the processor power supply to operate on +12V, and added the separate solved 12v 2.2 Power Supply ok? Retrieved 2015-11-30. ^ Evercase UK: Power Supply Measurements, retrieved 1 June 2016 ^ "In the World of Power Supplies, Don't Mistake MTBF for Life Expectancy" (PDF). I plan to get the EVGA SC model that doesn't need to be connected to the PSU.

It allows either a six-pin card or an eight-pin card to be connected by using two separate connection modules wired into the same sheath: one with six pins and another with the PC will likely freeze/crash by then so hopefully it notices something?UPDATE 2:Ok The SeaTools Long Test FAILED, and immediatley after that CrystalMark changed to "Caution" (I feel like I'm playing The maximum ripple might not be at maximum output current. share|improve this answer edited Jul 27 '14 at 1:50 Ricardo 3,966103057 answered Jun 28 '12 at 21:54 Olin Lathrop 210k23242554 In that case you could use the DC OK relay to quickly remove power instead of the power slowly ramping down as the output filtering caps discharge.

Rail Color mark 12V1 Yellow (black) 12V2 Yellow 12V3 Yellow (blue) 12V4 Yellow (green) Multiple +12V rails[edit] As power supply capacity increased, the ATX power supply standard was amended (beginning with There will be a symbol on the adapter showing which is positive and negative. The Antec Earthwatts 380 has one, but the Seasonic SS-400Es does not(I think). I ran a Short Drive Test, Self Drive Test, S.M.A.R.T.

TLDR, don't try using this adapter unless you are willing to risk damaging your device from the extra current. Rather than add more current limit circuits, many manufacturers have chosen to ignore the requirement and increase the current limits above 20A per rail, or provide "single-rail" power supplies that omit This laptop adapter supplies an output voltage of 19 V and a maximum output current of 3.42 A, well above your original adapter's 2A maximum. We get questions closely related to this regularly, so the purpose was to write a detailed answer once that we can point to in the future.

Then the HDD started the sound again and the system froze/crashed. Personal computers usually require 300 to 500W.[11] Power supplies are designed around 40% greater than the calculated system power consumption. Due to the always-on design, in the event of a short circuit, either a fuse would blow, or a switched-mode supply would repeatedly cut the power, wait a brief period of formfactors.org.

This is called current limiting. The original monitor PSU (PA-1650-68) was fixed at 19V and 3.32A. I use an Antec Earthwatts PSU and it is rock solid and quiet. Higher maximum power consumption required the buck converters no longer fed from the 5V and changed to a 12V input, to decrease the amperage required from the power supply.
