You can fit just about any motherboard in the case but would probably only consider an ATX or Micro ATX. ATX is the largest physical size mobo followed by the Micro. You wouldn't need to worry about anything smaller as they are more expensive anyway.
I would be inclined to replace the power supply also as that will be 'tired' and would probably struggle to power the new board. I never fit anything less than a 500 watt power supply. They're not that expensive anyway and it's always better to have power to spare than to be on the borderline.

Why is my hp pavilion 523w not working it just makes enough power to make a green light flash


The Green LED light you see flashing indicates you have a bad Power Supply.

Computer unplugged from power, computer on a table, computer case open, observe Anti-Static Precautions.
Clean the inside of the computer out with a can of compressed air for computers, (Or may take two, and a few Q-tips), and replace the Power Supply.

The Power Supply is an ATX form factor. The ATX style of Power Supply is found in over 80 percent of personal computers out there, and is readily available everywhere.

It's a 250 to 300 Watt power supply.
Probably made by Bestec, HiPro, or Delta, or some other generic power supply manufacturer of low quality power supply's.

Has a 20-pin ATX main power cable, and a 4-pin ATX +12 volt power cable.
Plus the usual amount of 4-pin Peripheral power cables, and a Floppy Disk power cable.

Is there a comptable power supply to replace FSP250-60HEN


Although ATX power supplies conform to various specification guidelines, there is not, unfortunately, a standard ATX power supply. To find a suitable replacement power supply for your machine, we would recommend that you have the following information to hand when making your purchase:

- You will require a PSU with a 24-pin ATX connector, SATA power connectors, and a 4-pin 12V motherboard connector
- Make a note of the wattage of your existing PSU
- Make a note of the external dimensions of your existing power supply
- Be aware that your PSU has a power connector for speakers. Most PSUs do not have this, so you may need to purchase a separate power supply for your speakers.

So it is a slight variation to a standard ATX power supply. If you are not using the speaker power off the power supply, then any standard ATX power supply will work for you

Power Supply Types

There are two basic types of power supplies. There are AT power supplies, which are older and in older computers, and ATX power supplies, which you will find in virtually every new computer you can buy.

There are two fundamental differences between AT and ATX power supplies. First, the switch mechanism is different. AT power supplies use a normal on-off switch, which directly turns the power supply on or off.

ATX power supplies use a momentary switch which does not directly control the power. Instead, the switch signals the motherboard, which performs one of three actions:

  • If the computer is off, the power supply is turned on (which turns the computer on)
  • If the computer is on, the computer goes into power-saving mode (standby)
  • If the switch is held for more than 4 seconds, the power is cut and the computer turns off.
Because of this difference, ATX power supplies are better for projects that require the second power supply to turn on automatically when the computer is turned on.

The second difference is in the motherboard connector: AT power supplies provide two 6-pin connectors (figure 1), which are easy to insert backwards. The ATX connector is a single 20-pin connector that only plugs in one way (figure 2).

Figures 1 and 2: The difference between AT (left) and ATX (right) motherboard connectors.
Both power supplies provide two types connectors for plugging devices into. These connectors are called Molex connectors, and they come in two sizes (see figure 3 and 4). A power supply will generally have a few of each size.
2psfig3small.jpg 2psfig4small.jpg
Figures 3 and 4: Large (left) and small (right) Molex connectors.
There is no difference between the two sizes other than the size itself. Both sizes provide the same amount of power to whatever device is plugged into it (12V and 5V). The small Molex connectors are generally used only for floppy drives. Large Molex connectors power hard drives, CD/DVD drives, and many fans and lights as well.

Note: You can purchase large and small Y-adapters if you run out of Molex connectors. Be careful when using the Y-adapters however, because if your power supply does not have enough power for all the devices attached (especially true for older, lower-wattage supplies), you can damage it.
