Motherboard Power Supply Question

[Jacobi]

Alright, well I'm looking at purchasing this motherboard here:

If you'll look at a couple of the reviews, they mention this:

I neglected to get a 20+4 pin power supply for I dont know what reason, but once I had that everything worked. If you have a GPU which 256MB dedicated RAM or above it is reccomended that you get at least 14 amps on the 12 volt rail.

I have a 256MB GPU. My question is, what does that guy mean by the 14 amps/12 volts/20+4 pin power supply, and what do I need to get one? The case I'm looking at buying is this:

Does that include enough power, or should I be looking at another power supply in addition? Thanks in advance for the help.

I'd recommend taking out the power supply that comes with that case and getting yourself a reliable one. Powmax are not really PSU makers, they are case makers (who include PSUs with their cases). In other words their PSUs are made with very cheap parts. You do not want a cheap psu. Read through this forum and you will see many people with really hard to diagnose problems that most of the time are the result of going cheap on the PSU.

To answer your questions briefly:

PSUs put out different types of power, as different parts on you computer like different flavors of power. There is 12v power for some parts, 5v power for others and 3.3v for the rest. A cheap PSU is not very good at making these different types of power, specifically the 12 type. A good PSU should be putting out at least 24amps as a minimum.

And the other question, your motherboard uses a 20pin connection from the PSU. Most new PSUs are a 24pin connection, but a lot of them have adapters that come with them, or better yet, the 24pin connector actually allows you to "snap" off 4 of the pins to change it to a 20pin connector.

I'd recommend getting a PSU from a company like enermax, fortron or Antec. Have a look at this thread for some great info:

What power supply you need depends on the hardware components in your system. Without that, nobody can suggest any psu that is suited for you.

However, as a general rule of thumb, I might take a look at the Enermax 565P-VE FMA. It is a Enermax 535w, 80 bucks at Monarch, with dual +12V with 34A combined (18 + 18 != 36 for some reason for Enermax...). That psu will run most high systems, but it is completely unnecessary if your system doesn't near use the power provided by Enermax.
