ZALMAN today introduced the MegaMax V2 line of entry-level power supplies. Available in capacities of 500 W, 600 W, and 700 W, these offer fixed cabling (black, ribbon-type), and 80 Plus (230 V EU) efficiency. Under the hood, you get a single +12 V rail design, active PFC, and DC-to-DC switching. You also get protection against over/under-voltage, overload, short-circuit, and overheat. A premium bit with this PSU is its 120 mm hydro-dynamic bearing fan. The 500 W model includes 8+4 pin EPS connectors, while the 600 W and 700 W ones include 8+8 pin. All three include at least a pair of 6+2 pin PCIe connectors, while the 700 W model includes four. The company didn't reveal pricing.

Wait, 80+ white label? And only on 230V? With DC-DC switching for the minor rails? What kind of utter crap design+component choice must this be for efficiency to be that bad with DC-DC? That's rather mind-boggling. I don't think I've ever seen that before.

Probably double forward primary, but low-end even for that as many double forward easily reach 80+ Bronze, I recall some even in Silver.
