New Power Supply Is Not Giving Full 12v Or 3.3v
For example in 3.3 v i get 6.6 v on 12.v i get 24.v etc.. There are alot of each type ... 3 Step 3: Presenting The PowerOK from all the other tutorials I've read there are a lot of different methods of connectors for connecting As with the +3.3 sense wire, these additional wires should also be connected to the corresponding supply lines. -- Main.SimonMcAuliffe - 01 Jul 2006 Updating this information to 2014: new ATX solved How many amps does my 12v rail have? weblink
Support service. Similarly to the minimum load requirement above, some older ATX PSUs require a load on their +5V and/or +3.3V rails to balance the load on the +12V rail and function properly. solved Is Corsair 650W, VS650, ATX Power supply enough to run gtx 970 and i5 6600k solved Is a corsair cx500m power supply good enough for gaming? A system without this feature only displays a message that it’s safe or ready for you to shut down the computer manually.
3d Printer Atx Power Supply
Some voltage regulators inside the PSU apparently have no trouble delivering 120 watts to a temperature controlled heated bed, others need to be oversized. Note that there is less than a 5% chance the PSU just can't handle the load of a hard drive. Mine just shuts off if I connect much of anything to it! The sense wire will usually be of a lighter gauge (22 AWG) than the power wires (16 or 18 AWG) and its purpose is to monitor the voltage at the connector
Ask ! Everything was fine until today. Some outdated instructions for doing a vaguely similar conversion can be found here:  The Duct Tape Method As discussed here. Modify Atx Power Supply For 3d Printer A PSU is not the right place to place your coffee cup onto.
This is one way of doing so. For about $10! If the power supply can’t maintain proper outputs (such as when a brownout occurs), the Power_Good signal is withdrawn and the processor is automatically reset. The power supply then sends the Power_Good signal to the motherboard, where the processor timer chip that controls the reset line to the processor receives it.

Any combination of ATX20 and ATX24 headers and connectors work. http://y2kconnections.com/power-supply/new-power-supply-problem.php The 3.3V sense wire needs to be connected to +3.3V. When the timer chip receives the Power_Good signal, it releases the reset and the processor begins executing whatever code is at address FFFF0h (occupied by the motherboard ROM). I will also reply you as soon as possible. Atx Power Supply Load Resistor

If bios is showing you as having low voltages I would see about getting an RMA. While I'm reasonably sure that there isn't enough residual energy to stop your heart, those capacitors can still bite, ... 2 Step 2: Opening UpOpen the PSU and make an assessment check over here If you have the means, test the hard drive in another PC.

Prusa I3 Power Supply The PCC then checks to see if PC is already on, possibly by checking the Power Good\OK signal which is generated by the PSU (Active High) or some other means. connect black with green to run it.
2.connect load (resistor 10W 5,0oms) in any red wire to stabilise all other outputs.
Thanks to instuctables.
Is there any way to get a higher voltage out?
Some motherboards are more sensitive to an improperly designed or improperly functioning Power_Good signal than others.
In one case, the load had to be applied to the 5v standby wire (purple) to ground rather than directly to the 5v rail to ground before the power supply would The yellow/black pair come from their own thoughts hole on the board and the gaggle of yellow come from 1 other larger hole. Am I reading the voltages correctly or am I doing something wrong? Atx Bench Power Supply Load Resistor A common example is when you replace a motherboard in a system and then find that the system intermittently fails to start properly when you turn on the power.

Although it seems as though the new motherboard is defective, it usually turns out that the power supply is poorly designed. note: The CPU power connector is usually connected to the power supply's second rail while the main(motherboard) connector usually has rail 1 power. Also modern ATX motherboards use much smaller currents from the 3.3V rail than older motherboards (from the e.g. It can provide 15 A from each rail.
I have a more basic question concerning how a power supply would be used to power a device.
If I have a device that requires
See Balancing_ATX_Supplies. Voltage Sensing The +3.3 VDC remote sensing wire (brown or orange) is connected directly to the orange +3.3 VDC at pin 11 of the power connector (pin 13 if a 2x12). Intermittent startup problems are often the result of improper Power_Good signal timing. If you now get the +12v line to come up, isolate by replacing one component at a time until you find the cause.
These are usually thinner wires, and should be connected to a wire of the same colour that they are connected to in the connector assembly. The main function of the +12 V power is to run disk drive motors as well as the higher-output processor voltage regulators in some of the newer boards. I will then explain what may be causing certain conditions not to be true and recommend solution(s) or additional steps to perform. Please discharge the power supply by letting it sit unconnected for a few days or connecting a 10ohm resistor between the red and black wires.If you hear buzzing when you turn
I measured with an analogue display multimeter.
3. Now take out the 4 screws on top of the case and take the wires out of the hole then group wires of the same colour together and snip off the Contents 1 Safety 2 Electronics prepared for PC Power Supplies 2.1 Base Load 2.2 List of PC-PSU enabled electronics 3 Required Minimum Specifications 4 Modifying a PC Power Supply for general They also may be affected by the motherboard and the +5v can be affected by the hard drive.
With these costing ... 1 Step 1: Harvesting & Preping The Power SupplyWarnings:BEFORE WE CONTINUE MAKE SURE YOUR POWER SUPPLY IS UNPLUGGED.Capacitors can bite and if not give a painful shock Only live wire is purple. Template:Clear Base Load Some ATX PSUs (not all) require a minimum load on the 5V rail to work properly. When in doubt, use duct tape.
Install the binding posts while using a small screwdriver to make sure they're all orientated right when you're tightening them down. Now Computer is working without a problem.. I will test it with other multimeters when I have the chance, to determine whether it is a measurement error or not.
I think the -12 +12 can cause some issues with Use the wire strippers to take off the ... 5 Step 5: HolesNow we come to the drilling.
