Antec Earth Watts Green EA-750 Power Supply Overview


  • Introduction
  • Packaging, appearance
  • Design features
  • Test results
  • Conclusion


Antec can be included in the list of brands whose quality is beyond doubt. Of course, there are more or less popular products, but the company did not have completely failed decisions. When evaluating cases, the external perception of the model and its layout are not in last place, so here some people may disagree with my statement.

What is a power supply? Iron, less often — an aluminum box, stuffed to the eyeballs with electronic stuffing. Making an iron box pleasing to the eye is much easier than a large case with many compartments, but good output parameters require only competent choice of circuitry and the same competent study, which Antec has never had problems with. Rather, they were seen in some eccentric and strange technical solutions by modern standards, but they did not affect the overall quality, so this cannot be considered a minus. By the way, according to a study by our colleagues at BeHardware, Antec power supplies have the lowest number of product returns in the industry — only 0.7%.

Three Earth Watts power supplies have arrived in the test lab. The current material is devoted to one of them —
Earth Watts Green EA-750

Packaging, appearance

The Antec Earth Watts Green EA-750 PSU comes in a small green/white cardboard box. The front side shows the power supply, the back shows the specifications and describes the configuration of the connectors.

The model, judging by external signs, is a budget one — the delivery set consists only of things necessary for installation and connection of the unit, shock-absorbing pads inside the box are made of low-grade cardboard. The traditional assumption: did all the money go into the block itself?


Cords are tied with two hard plastic ties. Pulling and snapping them together is not very convenient, the main plus is durability and reusability. But it would be better to put ordinary Velcro, it is easier to use them, and they hold well …

The body of the unit is made of thick (0.87 mm) steel, painted dark green. Its dimensions are 180 x 150 x 86 mm.

The cables in the EA-750 are standard, not modular. Their list and length can be found in the table:

Only the ATX24 cable is covered in black braid, the rest of the wires are simply intercepted with ties every 200 mm to avoid tangling. Considering the number of cords and their length, moving away from braiding in favor of cable ties is a plus: without it, the cables are more flexible, which means they are easier to tuck into the case.

A 135mm wide-blade fan is embedded in the top cover, and a sticker listing the electrical parameters of the model takes up the entire left sidewall.

The total power of the block is 750 watts, and, judging by the given data, it can give all of it through the +12 channel. Antec emphasizes that all watts are honest, that is, the power indicated on the label is constant, not peak.

On the label you can see the 80PLUS Bronze certificate showing that the PFC efficiency of this unit is in the range of 81 to 85 percent. Not bad, but for obvious reasons, this factor does not play a key role in the open spaces of the Russian Federation. Rather — a nice addition …

Design features

The first glance at the inside of the block showed that Antec treats budget models with the same responsibility as top-class solutions. At least the quality of mounting and soldering is very high.

Two chokes and input filter capacitances are clearly visible in the high-voltage part; on the left, the ribs of the radiator of the high-voltage diode bridge climbed into the frame.

You rarely see such an approach to a choke — the inserts separating the windings are carefully sawn out of textolite, and the rings are additionally fixed with glue on the mounting pads. In powerful power supplies from well-known manufacturers, you don’t pay attention to such trifles, but here all the small technological delights are very striking.

To the left of the input filter, an APFC choke and two electrolytic capacitors (manufactured by Samxon, 270 uF 420 V) are soldered. Immediately behind them is a radiator, on which the power switches of the APFC and the high-voltage converter are fixed.

Between the heatsink and the input filter elements, you can see the CM6800AG chip that controls the operation of the active PFC.
