Pros: Appears to be OEMed by ATNG (unconfirmed), the OEM responsible for numerous other good quality Rosewill branded PSUs. Build quality appears to be pretty good. I believe this is probably stepping in as the replacement for the "green" series from Rosewill. Works as intended. Provides safe, stable, reasonably clean power.. The Bronze efficiency rating seems to be on the conservative side, which is nice. The topology used is certainly capable of achieving very high efficiency. Sleeved cables is a nice touch at this price point.
Cons: 1x6pin and 4xSATA power is an artificial "clamp" placed on this PSU that more or less ensures it will always be used at half of its label rating or less. 2 X 6pin and 6 X SATA would have made the 450W ARC a stronger competitor. As it stands now, it's just a valid alternative to a CX430.
Overall Review: Middle tier component quality used throughout is expected at this price point. Chinese capacitors are from Teapo. The secondaries I can spot are 105C rated and are the same quality found in many other middle tier PSUs from OEMs like FSP and Delta. The component quality is probably the only thing holding the efficiency back from being a "gold" rated unit. Mosfet resistance being the primary issue.
