If you’re looking at building mid-range gaming or productivity systems or upgrading what you currently have, Rosewill’s VSB 650W and VMG 750W models are definitely worth checking out, as they are currently very good deals thanks to special coupons (purchase links under the specs table down below). Both units are designed around Intel’s ATX 3.0 and 3.1 guideline specs, which means they’re prepared for the new standard that modern graphics cards can demand.
First up we have the VSB 650, which is a semi-modular unit carrying an 80+ Bronze certification. One of the key highlights is its inclusion of a native PCIe 5.1 (12V-2x6) connector, capable of delivering up to 450W to dedicated GPUs.
Cooling is handled by a 120mm "silent" fan, paired with a steel shell and venting design intended to keep temperatures in check. Rosewill also specifies the use of "Japanese" capacitors rated for 105°C, which suggests excellent tolerance and durability under sustained load.
Stepping up, the VMG 750 moves to a full modular layout. Thus you only connect the cables you need, which reduces clutter and improves airflow. It carries an 80+ Gold certification, so efficiency should be higher than the Bronze unit. Like the VSB650, it supports ATX 3.0/3.1 and includes the same PCIe 5.1 connector, but here the dedicated line can deliver up to 600W to GPUs.
Both models come with a five-year warranty, and they should be able to power most of the mid-range GPUs from AMD and Nvidia.
