The OEM is still Sirtec/High Power. It looks like its based on the High Power Element Smart series platform.
Pureoverclock's review of the 750W model said that it was slightly noisy at load and the cables aren't long enough for full tower cases.
Cables not long enough for full tower cases have always been a major complaint of OCZ PSUs so this hasn't changed. It was a direction made by OCZ to reduce the BOM.
Well, shorter cables are a good thing for the large majority of people who use reasonably sized cases.
