Specifications
The Neo HE 500 power supply supports ATX12V v2.2 and EPS12V systems and is rated for a combined, maximum output power of 500 watts with a maximum ambient temperature of 50°C. This is an important feature and is an area where some less reputable manufactures mislead their customers by significantly limiting a power supply’s full load output if the internal operating temperature exceeds 25°C.
The Neo HE 500 includes universal input with active PFC and provides three separate +12V outputs, each rated for up to 17A. Voltage regulation is held to ±3% for the 3.3V, 5V, and 12V outputs.
The Neo HE 500 power supply comes securely packed in a large box and includes a power cord, mounting screws, seven modular cables, and a detailed multilingual User’s Manual.
Triple +12V outputs
The Antec Neo HE 500 PSU incorporates three 12V outputs (+12V1, +12V2 and +12V3). The following table shows the maximum rated current and what connectors are supplied by each of the +12V outputs.
Note: The maximum combined load for the +12V1, +12V2 and +12V3 outputs is 38A.
Higher Efficiency
One simple way to boost a power supplies overall efficiency is to lower the +3.3V and +5V output capacities while increasing the +12V outputs. It’s easier to efficiently convert the AC line voltage to +12 VDC than it is to the lower +3.3V and +5V outputs. After looking at the specifications for the Neo HE 500, it appears this is in part what Antec has done to boost efficiency levels.
Excellent PSU! Glad to see
Excellent PSU! Glad to see that it is still marketed. I have this PSU in a steel case ANTEC tower which was acting as a server. I have the MAIN SERVER tower and a newer case from your company, too. The first mentioned has an ancient but very well endowed ASUS board.
I would like to buy extra pluggable cables for the supply because I shall use it with a more advanced motherboard.
Also; please inform and let me know if (upon opening PSU) Voltages can be tweaked. (I’m electronics engineer so no problem with spoiling anything!
Thank you, Robin Marstrand.
I would also like the .PDF
I would also like the .PDF maintenance manual.
Thanks, Robin.
I have an issue with this PSU, maybe you can help.
I’m trying to jump start it without a computer. I connected the right pins (green and black).
The fan spins as soon as I turn it on, however, as soon as I connect it to any device the PSU turns off.
Thanks in advance.
