Enhance EPS-1812GA4

This high-wattage model from Enhance has been showcased at different expos but hasn’t yet made it to the shops. Let’s see if we should really look forward to it.

Exterior Design

At a length of only 160 millimeters, the EPS-1812GA4 is the most compact of the PSUs in this review.

The compactness comes at the expense of modular design. The numerous cables that such a high-wattage PSU is supposed to possess have to be somehow accommodated inside your computer chassis even when not in use.

Otherwise, the EPS-1812GA4 looks ordinary enough with its smooth matte-black paint, 140mm fan, and honeycomb-mesh vent grid of the back panel that lacks an On/Off switch. The rest of the panels are blank.

Circuit Design

Like the Cougar model, the EPS-1812GA4 follows the well-established trends with its interior design.

Notwithstanding the small dimensions and high wattage rating, the component density isn’t too high. This is largely due to the PSU’s having only one power transformer.

The characteristic fingered heatsinks hide DC-DC converters that the PSU employs to generate +3.3V and +5V voltages, just like the other PSUs in this review.

There are Nippon Chemi-Con capacitors at the PSU’s output. They are rated for an operating temperature of 105°C.

Cables and Connectors

The EPS-1812GA4 is equipped with the following cables and connectors:

  • Mainboard cable with a 20+4-pin connector (50 cm)
  • CPU cable with a 4-pin connector (52 cm)
  • CPU cable with a 4+4-pin connector (52 cm)
  • Two graphics card cables with one 6+2-pin and one 6-pin connector on each (52+15 cm)
  • One cable with three PATA power connectors (52+15+15 cm)
  • One cable with three PATA and one floppy-drive plug (52+15+15+15 cm)
  • Two cables with three SATA power connectors on each (52+15+15 cm)

Unfortunately, the main cables are too short for large system cases. This is a regrettable shortcoming in a PSU that is meant for top-performance PC configurations which can hardly be assembled in compact system cases.

Of course, there is also the inevitable downside of the non-modular design: you have to lay all those cables out somehow in your chassis because you cannot remove unused ones.


The EPS-1812GA4 meets today’s requirements with its specs. It can give its full output power across the +12V rail (which is split into four “virtual” lines with a max load of 40 amperes each) and can provide enough power to +3.3V and +5V devices (each of these rails has a load capacity of 25 amperes; their combined max load is 180 watts).

Although there is no official 80+ certification for this PSU, the manufacturer claims it meets the Gold version of that standard.
