Ultra X3 800 watt power supply

Doesn't power up when turned on (at the main switch) does the mobo have to be connected to the ps before it will turn on? Or do I have a bad ps??

I am not sure if i totaly understand your question?
your mb will not turn on until you turn it on after connecting it to the front panel.the switch on the powersupplie only turns the power supplie on.you need to locate two pins that say power .short those with screw driver should turn on.

Yes PWR SPLY must be connected to MB and MB must be grounded when bench testing. thats the quickest easiest way to check..

Pin out for a dell PS-5201-8D2 power supply


Use caution, some older Dell machines used a non standard, proprietary pin-out on the 20 pin connector ALso the 6 pin is suspect. If you connect a regular ATX PSU, you will fry the MoBo. Look here

Mainboard: g31 m7 te - power: antec hcg750 - gpu: gtx560ti


No the mobo is compatible with the Power Supply, and GPU.
And vice-versa.

Mainboard fan???????
You mean the Processor (CPU) fan?

I'm guessing I guess, because computer case fans aren't on the motherboard/mainboard/mobo.
(MOtherBOard)

You're getting power to the mobo, but the question is how much?

1) IF ALL of the LED lights were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use from 51 to 125 Watts of power.
Just depends on what Processor it is.

http://206.108.48.60/app/en/mb/introduction.php?S_ID=363&tab=1

The mobo will support Intel Core2 Quad-Core processors. Depending on which one, you may be talking about Up To 105 Watts of power,

http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors#Quad-Core_Desktop_processors

This is why LED's can light, and fans may spin, but the Processor isn't getting enough power, so the computer will not turn on. (Processor isn't turning on)

Why?

1) Just because that Power Supply is new, doesn't mean it is good.
Sometimes you get a bad one. Test the three main voltages coming out, with a multimeter set to DC Voltage.

Need guidance post back in a Comment.
(An economical multimeter can be purchased, for as little as $8 to $12. I have seen cheaper. Available in a multitude of stores. An auto parts store is but one example )

2) You don't have the 4-pin ATX +12 Volt power cable plugged in.
Goes to the white square 4-socket hole connector, to the left top corner of the Processor socket.
(Motherboard installed in computer case)

3) REQUIRES -> TWO 6-pin PCI-Express power cables, for the Nvidia GTX560Ti graphics card.

The Antec HCG750 PSU has 4 of them, so no problem there, IF you have two of them plugged into the graphics card.

Both connectors of the 20 + 4-pin ATX main power cable's connector, need to be used. Biostar mobo requires a 24-pin ATX main power cable.

Post back in a Comment as to power cables plugged in, and DC Voltage test on PSU.

hmmm...usually this is a function of the output load this means your 650 watt ps might be trying to turn on to too much current drain

what is it powering?

Green light flashing on compaq presario - computer will not turn on


You may have a 12V ATX line (6 wires) that needs to be connected to the mobo in addition to the main power (about 20 wires). Make sure they are both connected - try again.
Remove 1 stick of memory - try again.
Swap the stick you removed with the other stick and try again.
Unplug the power switch wires from the header on the mobo - try again - make sure you write down where each wire goes. Try again.
Swap the power supply with another ATX to see if it is the power supply (PS fail more than mobos due to dust buildup).

Any doubts you can get the help of a technician through

So you changed everything except 1 thing, power supply. Try another power supply or power suply cord.
If it doesn't work, try another graphic card, maybe there is some shor circuit.

Ultra 750 watt power supply ,+12 dc volt output showing ac component of 1.5 to 2.7 volts on new unused ps


Is this with or without a load?
There is always some ripple on the DC output of a switching mode power supply, and the less the load, the greater the ripple.
Measure the power supply under full load, that's the real test!

E Machine ATX 250 -12E replacement PS


With emachine MOBO's you have to make sure you plug in the 20 pin plug from the power supply to the mobo. Also make sure all hard drives, cd/dvd roms, floppy drives, etc are turned on. Make sure the red switch on the PS is set to 115. Make sure the PS is plugged into a known working outlet. Make sure MOBO is properly in place with all grounds/screws in place and nothing metal near or touching board which may short it out.

You can review the E Machines PS replacement guide here for further instruction.

Good Luck,

Jesse

Power supply has several voltages. Just because the 5v power is active doesn't mean all the voltages are OK. You need to have the power supply tested for 12v and 3.3v. A quick test is to unplug all the wires from the power supply. There is a single green wire on the motherboard main plug. Connect (use a bent paper clip) that green switch wire and any black wire. Plug in the power supply and it should run (fan starts)

Computer Build Problem


Try taking out the mobo and ps out of its casing, lay it on a table, hook things together and power it up. I had some problems before caused by mounting studs or try insulating all stubs from the mobo. hope this will help.

Diagnosis


Some power supplies have a microswitch that prevents a turn on while the case is open. Sometimes it's a switch on the case, or a switch linked to the mobo. You can try to defeat that. Also PSU's are made so they won't turn on unless hooked to a mobo. You will have to jump some pins to defeat that. This info is readily found in Google.
