Power Supply I would like to upgrade the power supply in my HP Pavilion A730N. Is this possible?

    The computer currently has a 300w power supply. I would like to continually be able to upgrade the video card as time goes by. Most of the nice cards require more than 300w. This is why I need to know if I can upgrade the power supply.

Is there a problem you are encountering? does your pc shutting down? what is your present power supply wattage? if that is 300watts then you can change even 450watts.

I have a yellow blinking light on the power supply of an HP model A000 Pavillion computer. What does that indicate?


if your power supply light is blinking and wont reset that means a component in the power supply has failed or fried or something unknown happened and will have to be replaced

My a730n computer will not turn on. The green light flashes in the back. Local frys tested power supply and said it was working. Fans dont come on...nothing?


it could be a mother board problem or Power supply issue. Even if the power supply works it wont supply required voltage to some components.Its better you get a new power supply and test it.Still its not working it could be a mother board issue.There will be a chance for power button issue also.

My a730n will not turn on and the green led power light on the back is flashing


This indicates there is a problem with the Power Supply.
You have a weak voltage power rail.
Components inside the power supply have failed.

Most of the time this due to the power supply, as well as the inside of the computer is dirty.
The rest of the time it is due to a cheap quality power supply from the computer manufacturer.

You can be the best housekeeper in the world, but inevitably dust, dirt, and other material is drawn into your computer.
Your computer uses air to cool the hardware components inside.

Air is drawn in through the front of the Pavilion a730n, and is exhausted out of the back.
(There is one computer case fan in the back, and the Power Supply fan also helps)
This is the computer's Cooling System.

The cooling system for the Power Supply is a fan on the back of the unit, and Heatsinks that are inside.

(A Heatsink is a small plate of metal, with tall fins on it. The Heatsink works as a small radiator. Heat is absorbed up through the fins. Air is drawn through the fins, and heat is pushed away by the air)

When the fan blades, center hub, and surrounding cage become clogged with the above mentioned material, the cooling capacity drops tremendously.
Same thing for the Heatsink fins when they become clogged.

Heat = Wasted Energy
The Power Supply strains to keep up with the power load that is needed, and the additional loss of energy, (Power), that is lost due to heat.

Eventually components inside the Power Supply fail.

Commonly it is the Electrolytic Capacitors that fail first.

Computer manufacturer's commonly use cheap quality Power Supply's. They buy them from a Power Supply manufacturer.
Cheap quality = the computer manufacturer saving money, because the unit's cost them less.

1) Cheap Electrolytic Capacitors
2) Too small of a gauge of wiring is used
3) Cheap quality Rectifier Bridge
4) Cheap MOSFET's
The list goes on.

Solution is to replace the Power Supply.
Power Supply's come in many sizes, and power designations.

The HP Pavilion a730n uses the common size, and shape of Power Supply, used in 90 percent of personal computers. ATX

The power designation is 300 Watt.
Usually it is a Bestec, Delta, or HiPro power supply that is used.
C-H-E-A-P!

Based on personal experience, I would recommend this power supply for a replacement unit,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4675269&CatId=1078

Not an advertisement for said website. You may find a better price by searching.

Know this:
A computer only uses the power it needs, and no more.
Example:
You could install a 1000 Watt power supply in your computer, (Not actually. It will not fit), and if your computer only needs 100 Watts,
it only uses 100 Watts.

(Typically surfing the internet uses 100 Watts. Same as a 100 Watt light bulb)

This is HP Support, Pavilion a730n, and the Manuals page,

http://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&dlc=en&cc=us&product=431078&lang=en&

On this page you can download the Part Replacement Instructions manual.
Has large illustrations, to show how to replace parts inside the Pavilion a730n Desktop PC.

Power Supply replacement is shown.

From me:
If this is your first time in replacing a computer hardware component, this may seem like a daunting task. Once you are finished you'll realize it wasn't all that tough.

Inside your computer you'll see many cables, (Wires)
You'll see cables coming from the Power Supply, that go to the various hardware components inside.
(Motherboard, Harddrive, and CD/DVD drive/s)

Power cables from Power Supply
1) You have a cable with many wires in it. It has a white connector on the end, and is long in shape.
It has 24 socket holes.
It's a 24-pin ATX main power cable.

Connects to the motherboard. To release it from the motherboard, there is a lock tab on the side of the connector. Press the lock tab at the top. This pivots the lock tab, and draws a hooked end, out of the side of the motherboard connector.

Gently wiggle the connector side to side, while depressing the lock tab, ease it up.
(Side to side lengthwise)


2) You have 4-pin Peripheral power cables. (Also referred to as Molex)
White in color, 4 wires. (Red, Yellow, and two Black)

One to each CD/DVD drive you have.

3) You have One SATA power cable. Connects to the SATA Harddrive

4) You have One 4-pin ATX +12 power cable. The connector is square in shape.
Has two Yellow wires, and two Black wires.

This power cable is for power to your Intel Pentium 4 processor, and Must be plugged in.
Plugs into the motherboard.

This link shows the various power cables, and connectors, that I listed above.
(Large photos, and clear information)

(Scroll the page down, to view all of the power cable connectors. Click on a photo of a connector, to view more information about it)

Should you need more information, just click on Comment, and type it out. (Believe top right of your page)

Power doesn't turn on


NO! Do not buy a new motherboard or pc without checking some things.

First, is the green light you say is blinking on the Power Supply itself?

If it is, then the power supply is dead. A blinking light on a PSU means that it can no longer hold a charge and needs to be replaced. Get a new one and pop it in.
