Antec is one of the oldest & best known manufacturers

of high quality, stable power supplies. Antecs new range

is the Neo HE line. The Neo HE line consists in 4 models

(380w, 430w, 500w, 550w.) The range of power supplies

are designed as energy efficient. Hence the name 'HE'

meaning high efficiency.

Antec give a brief of what 'HE' actually means:

The new range of power supplies energy efficient

operation reduces power consumption by up to 20%

compared to other power supplies on the market today.

Resulting in less heat being generated by the power

supply, meaning a slower, smaller & quieter fan will be

needed to cool the power supply. The result of this is a

cooler, quieter, and more eco friendly power supply.

Appearance:

The power supply is painted in a dark grey matt colour,

nothing fancy or flash. However with PSUs it’s the

insides that matter. The quality of brading on the cables

(both permanent and optional cables) is outstanding.

The cables are braided using high quality black sleeving

making the power unit appearance looking very high

quality, however i found that the heat shrink did not go

right to the end, which made about 5% of the cable near

the connector viewable. On the rear there is a 80mm

exhaust fan which is a ADDA branded, very high quality

fans which are extremely quiet and effective.

Permanent Cables:

There are three permanent cables on this modular power

supply. The EPS12v (8 pin), ATX Cable (20/24 pin), and

the 12V ATX (4 pin). The EPS12v cable should be used

when possible, if there is no connector on the

motherboard for this cable, the 4 pin 12v ATX cable

should be used. The ATX cable is not optional; it needs

to be plugged in! I found that the 24 pin ATX cable had

quite a neat idea on the connector. For systems that do

NOT use 24 pin, you can simply slide off the 'extra' 4

pins that are on the connector.

Modular Cables:

There are seven modular cables:

Molex Connectors *2, Floppy Connector *1, Pci Express

Connectors *2, SATA Cables *2.

In total there are 6 molex connections, 2 floppy

connections, 2 pci-express connectors, 4 SATA

connectors.

Stress Testing:

Tests were made to see how good this power supply

actually is. I used a multi-meter to record results, Idle

results are normal pc usage - internet browsing, and

standard background applications. Load was tested with

prime 95.

Results:

Idle: 3.3v: 3.31 / 5v: 4.99v / 12v: 12.00

Load:3.3v: 3.31 / 5v: 4.99v / 12v:11.96

Conclusion:

If you have been browsing tonnes and tonnes of reviews

on power units, this unit is more than capable of

supplying enough power to a monster system whilst

staying absolutely quiet. The noise from the unit is just

unbelievable! I have to put my ear right near the grill for

me to even hear the fan spinning, I even thought that it

had stopped working at one point! Antec have

successfully proved that you do not need high powered

fans/noisy power units for a power supply to be capable

of powering a beast of a system.

The only thing that I could pick out to be disappointed

with this power supply is the braiding. The actual

braiding quality itself is very high of quality, however

close to the connectors there had been a 'lack' of heat

shrink which revealed the cable slightly (about an inch

or two) which did disappoint me slightly as there are no

other faults with this unit.

This power supply currently retails for £88 at

Overclockers, which I think is an amazing price, given

for the quality of the unit. Not only is it amazingly stable,

but it is the quietest power unit I have ever used. (I have

been through a fair few). This power supply is definitely

recommended as it is not over-priced but still brings

amazing performance.

Pros:

- Silence.

- Efficient with low heat output.

- Amazing Voltage stability.

- Quality of the sleeving.

Cons:

-Not being fully sleeved at the end of each connector.

-Not being able to connect every modular cable if you

needed to.
