4 out of 5 eggsAn acceptable compromise.

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.

Other Thoughts: 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.

4 out of 5 eggsJust the right amount of cables

Pros: Just the right amount of cables for a typical home build. 2 strands of Sata (5 plugs total), one strand of molex (3 plugs total), one strand of pcie (1 plug total). Even though its not modular, there isn't much extraneous hanging around resulting in a clean build. An unexpected bonus is that the 24 pin and 4 pin power connectors for the motherboard are pretty long. I was able to run them behind the mother board in a fractal r4 (mid tower case with bottom mounted power supply).

Cons: Not enough pcie for two video cards but you knew that from looking at the specs.

5 out of 5 eggsDirt cheap with rebate!

Pros: Great price for an 80+ Certified PSU!
120mm fan = Quiet
Runs great in an HTPC build with two HDs and a Quad core AMD 5450 Kabini with a Blu-Ray drive.

Cons: None so far!

Other Thoughts: If this PSU holds up for over a year....it's a bargain.

Rebates suck!
