DreamWare Computers posted a review on the Nexus RX-5300/RX-6300 Power Supplies

Nexus is no newcomer to the growing group of companies trying to bring you high performance, ultra-silent computing peripherals. Being around since 2000, Nexus have 9 years worth of continuing product development behind them. Their product lines range from a growing power supply collection to computer cases and all sorts of high performance computing accessories. The products I've reviewed from them in the past have generally gotten all-around positive reviews and many of their products can be currently found in use in several computer systems throughout my home. Recently Nexus has released two new models in their RX series of power supplies; a 530W and a 630W (these in addition to the higher wattage models already available). I was lucky enough to receive one of each here today to put through the paces.
