Final Thoughts and ConclusionsThe Nexus RX-5300 – 530W power supply delivered very good efficiency with relatively clean outputs and good voltage regulation. Its main feature however is how quiet it is – virtually silent. Not only does it start out quiet it stays that way throughout the power curve. At full output the fan just becomes audible. Throw in modular cables, support for high-end graphic adapters, and a good assortment of peripheral cables and you have an nice PSU for a HTPC or other quiet computing application.
My main complaint with the RX-5300 power supply (and the only reason it didn’t bring home gold) is the limited 2-year warranty, which seems out dated when many other high-quality power supplies are now offering 5-year, 7-year, or lifetime warranties.
The Nexus RX-5300 – 530W power supply is currently available ( Cool Tech PC and Endpcnoise.com ) and sells for $109.00 USD (12-2009).
