Try to jump start it with a screwdriver, just touch the screwdriver to the place where the power connection (from the front) cable plugs in. If this works, you need to plug the power into there, if not, you may not be hitting the right spot, or the psu/mobo is bad.

Power supply diagram for ht 2000 motherboard

1) Uses one 24-pin ATX main power cable.

Motherboard installed in computer case, the motherboard connector for the 24-pin ATX main power cable; is to the Right of the Blue IDE (PATA) connector.
(Right side of motherboard)

General example. Note that color does NOT matter of connector,

2) Uses one 4-pin ATX +12 Volt power cable,

Motherboard installed in computer case, the whitish square 4-socket hole connector, to the Bottom/Left corner of the Processor socket; is the 4-pin ATX +12 Volt power cable's motherboard connector.

General example. Note color does NOT matter of connector,

THAT, would be considered a Power Supply diagram of the motherboard.

They are the only two power cables that plug into the motherboard.

The front of your desktop computer is the Front Panel.

The area of contact pins on the motherboard, that the Main wires from the Front Panel go to, is the Front Panel header.

Power On switch, Power On LED, (Light Emitting Diode), Harddrive activity LED, and a Reset switch IF used.

Replace motherboard

Rob, Rob, Rob.............if I told you a thousand times, I............

Oh.......... where was I?

1) Power cables from Power Supply to motherboard:

A) 24-pin ATX main power cable;

Looking at the motherboard view the Right side. To the right of the Blue 39-pin IDE connector, is the 24-pin ATX main power cable connector, on the motherboard.

This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

The power cable connector has a Lock on one side, and the motherboard connector has a matching Lock Tab.
When the power cable is deemed to be installed Correctly, and Properly; the Lock's hooked end is over the Lock Tab.

[Note* Color of connectors does NOT matter ]

B) 4-pin ATX +12 Volt power cable;

The processor socket is white in color. Around it is the black mounting ring.
The 4-pin ATX +12 Volt power cable connector on the motherboard, is to the Left/Bottom corner, of that black mounting ring.

Square, whitish (Opaque), and 4 socket holes.
This is a general example of a 4-pin ATX +12 Volt power cable; and it's respective connector on the motherboard,

2) Peripheral power cables from Power Supply;

A) The Harddrive is a SATA unit. Uses a SATA power cable,

B) The optical drive/s (CD/DVD drive) are also SATA units. They use a SATA power cable.

A SATA power cable's connector has 15 contact pins. Between it, and the SATA data cable, it has the longer connector.

Peripheral Data Cables;

This is a general example of a SATA data cable, it's connector, and a SATA connector on the motherboard,
(Note* Color does NOT matter),

Here you can see the L-shaped opening of the connector, and matching L-shaped tab on the motherboard connector.

Most SATA power cable connectors, and SATA data cable connectors, have a lock. All you see is a 'bulb' type affair on top of the connector, that you squeeze down with a thumb tip.
Depress to remove, depress to install.

A 90 degree elbow connector for the SATA data cable, is used on the Harddrive, and optical drive. The straight connector end of the cable, plugs into the motherboard.

There are two SATA connectors on the motherboard. One White, one Black. One of them should have a SATA1 next to it.
(Or one will at least have SATA2 next to it)

SATA 1 connector is for the Harddrive. SATA 2 connector is for the optical drive.
The beauty of SATA is though, you can connect any SATA device, to any SATA connector on the motherboard; and BIOS will find it.

So it really doesn't matter what you plugged in where, as far as those two SATA headers are concerned.

3) Processor Fan cable, System Fan cable (Computer case fan);

Going back to the HP Support page above, and Motherboard Specifications; scroll down the list.
Click on the + sign to the left of the blue - Motherboard layout

Below the ATX12V1 connector is the System Fan connector.
This is where the computer case fan connects.
(ATX12V1 connector, is the 4-pin ATX +12 Volt power cable, connector)

Above the Ram Memory slots, and a little to the right; is the Processor Fan connector. Power to the fan. (CPU_FAN)

4) Front Panel audio connector, optical drive audio connector, Front Panel USB connectors;

Bottom edge of motherboard, from Left to Right;

Yellow connector is AUDIO1. Front Panel audio.
White connector is ATX_IN
For the audio cable from the optical drive.

Black connector (HD_AUDIO) is also for the Front Panel audio.

Don't know how they have the Front Panel audio, hooked up.
YOU will. The cable connectors to them are different from each other.

Front Panel USB connectors;
Further to the right are two white connectors. EACH one can support TWO USB ports.
One should be for the two USB ports in the Front Panel.
The other will go to a Card Reader in the Front Panel.

All the way to the right corner is the Front Panel header.
This is where the main wires from the Front Panel go.

Power On switch, Power On LED (light), and Harddrive activity LED (light)
The cable, and connector should match that 9-pin header.
If not here is an HP 9-pin Front Panel header - pinout,

Scroll down to the photo, and pinout. (Dave G)

Believe that is it.

For additional questions, or to have me clarify anything I have stated above, please post in a Comment.

I just built a new computer and when i tried to boot it up nothing happened. The Corsair ax850 PSU isn't even "humming" or giving any indication that it has power. The 110v wall plug has power....

You won't get any 'fireworks' or 'smoke', widsss.

A) Make sure the Power On switch is connected to the correct pins, in the Front Panel header on the motherboard.

(The Front Panel is the plastic front of your computer where the Power On button, HarDDrive activity LED, Power On LED, etc., is located.
The pin area on the motherboard that the Front Panel cables (Wires) plug into, is the Front Panel header)

Either you do not have
1) The correct cables (Wires) plugged into the motherboard from the Front Panel,
2) A bad Power On switch,
3) A bad Power Supply
Even if the Power Supply is brand new, it can still be a dud.

There is a simple test to see if the problem may be the Power On switch, or the Power Supply.
After you have made sure the problem is not incorrectly attaching the wrong wires, from the Front Panel to the motherboard, reply back in a Comment, and I'll detail out the simple test for you if you wish.

B) Make sure the 4-pin ATX +12 volt power cable is plugged in, if your motherboard uses it.
It's power for the Processor.

C) Your motherboard may not use a 4-pin +12 volt power cable. It may require more power.
In this case an 8-pin EPS +12 volt power cable is used. The equivalent of two 4-pin +12 volt power cables.

1) Red wires are 5 volt
2) Yellow wires are 12 volt
3) ANY Black wire you see is a Ground wire )

I await your findings.

I am having a problem connecting my power supply to my motherboard i can plug in everything except the one connectors that require a connection to a part called PWR-LED

Take a look at the picture below:

If I am right, the Front Panel connector should look similar as shown above (it's an assumption since you didn't mention the Motherboard's name and version). Look at the front panel connector on the motherboard carefully, you'll see similar name/indicator as you are seeing on the above picture like Pled, Hdled etc... I hope the front panel connector has 9 pins, and remember, one should be left without any connection.

Simply you have to connect the two female Pwr-Led to the Pled+ and Pled-, and Power to Pwr and Gnd, the same sequence with hard disk led and Reset switch as Hdled+ and Hdled- and Gnd and Reset respectively.
If the front panel connectors on your motherboard has less than 9 pins, then I am sorry, I have no idea about it and I am afraid if it exists or not.

If you still have the problem, let me know.

Good luck.

Thanks for using FixYa.

If you have not removed the old motherboard from the case, then you can identify the various front panel connectors as you disconnect them and label them. Some front panel connectors have labels printed on the connectors which makes it easy for you to identify its purpose. If you have already removed the old motherboard then you will need to trace each of the leads to the front panel to see what they are connected to (eg. the LEDs and switches etc).
You will also need to identify on the new motherboard the various connectors for each function, eg power LED, hard drive LED, reset switch, power on switch, internal speaker etc. If you are lucky It may be printed on the motherboard, if not you will need to refer to the manual.
NOTE the LEDs are polarity sensitive, if the LED does not light, then swap the connector around the other way.
