Silverstone today introduced the VIVA line of mainstream PSUs. Available in mid-range capacities of 550 W, 650 W, and 750 W, these PSUs offer fixed cabling, and cover all the essentials for a gaming PC build. Under the hood, the VIVA series features a single +12 V rail design, 80 Plus Bronze efficiency, active PFC, and most common electrical protections, against over/under-voltage, overload, and short-circuit. All three models offer flat black cables. A 120 mm noise-optimized fan with 18 dBA minimum noise output, cools the PSU. All three models come with two 4+4 pin EPS connectors. The 750 W model includes four 6+2 pin PCIe power connectors, while the 550 W and 650 W models have two. The VIVA series PSUs are build in a 14 cm long chassis. The company didn't reveal pricing or warranty information.
