Antec EarthWatts 750W PSU Review

Antec, one of the best known computer power supply companies today shares with us its EarthWatts 750W PSU. New marketing seemingly pointed at being green means better efficiencies and lower power bills? We will see if the EarthWatts PSU is worthy of its namesake.


One of the most prevalent companies in the consumer power supply realm, and general enthusiast PC realm, is Antec. Antec is a company that has been kicking around the PC DIY market since 1986 and in that time frame has become one of the most widely known brand names. In addition to power supplies Antec has product lines that include cases for work and play, cooling solutions, lighting, and other accessories. Over the years Antec has used a number of OEM providers for their power supplies including HEC, CWT, FSP, Enhance, and recently Seasonic. Some of the older Antec/CWT solutions were notorious for being plagued by the "Fuhjiyyu sudden death syndrome," but in the last year or so Antec has dropped these older designs in favor of new products from FSP (Basiq), Seasonic (TP3, NeoHE, TruPower New, EarthWatts), Delta (EarthWatts) and Enhance (Quattro). Today we will be looking at an offering from Antec that comes from Delta once more, in the Antec EarthWatts 750 (EA 750).

Delta Electronics Inc is part of the Delta Group and is one of the older presences in the power market in Taiwan as the Delta Group was founded in 1971. As an OEM Delta has been popular among higher end server solutions and for a selection of prebuilt PC’s from major worldwide consumer PC OEMs for many years but rarely has Delta shown up in enthusiast applications. Currently, Delta claims the title of the world's largest supplier of switching power supplies. However, even with a lack of presence in the power supply side of the DIY market Delta is still certainly a known commodity as most enthusiast users have certainly encountered their fans at one point or another. Today’s review of the Antec EarthWatts 750 gives us our first look at a Delta-based offering that is not a premier offering such as the Signature 850 was.
