Final Thoughts and Conclusions
The Enermax TriAthlor 550W power supply delivers good voltage regulation with clean DC outputs (low AC ripple) and is housed in a compact chassis that is only 140mm (5.5”) deep. The TriAthlor 550W power supply is eco-friendly by meeting the new ErP Lot 6 standby efficiency criteria but achieves only 80Plus Bronze level efficiency under load. Under light to medium loads the power supply is quiet, but at the higher loads fan noise becomes noticeable. The TriAthlor 550W PSU comes with a good assortment of fixed and modular cables that can support the latest CPUs and graphic adapters along with active PFC and universal AC input.
The Enermax TriAthlor 550W power supply is currently available and selling for around $109.99 USD (newegg.com April 2013), which makes it relatively expensive compared to the competition at this power point, considering it is only backed by a 3-year warranty and 80Plus Bronze certified.
