myVolts CMX700 700W ATX12V EPS12V 80 Plus Bronze 140mm Modular Power Supply

700 W modular supply for gaming builds

This power supply delivers 700 W of continuous output and carries 80 Plus Bronze certification with up to 88 % peak efficiency. It targets gamers and enthusiasts who want reliable power for mid-range to high-end graphics cards and multi-GPU setups without paying for higher-tier ratings. The fully modular flat-cable design lets builders connect only what they need, reducing clutter and improving airflow inside the case. Japanese capacitors rated at 105 °C provide four times the lifespan of standard 85 °C parts.

Capacity headroom and limits

The unit supplies a combined 12 V rail design with full protection circuits including OCP, SCP, OVP, UVP and OPP, giving stable power to demanding components under load. It handles SLI and CrossFire configurations comfortably within its 700 W budget, leaving headroom for overclocked CPUs and multiple drives. Builds requiring more than 700 W or those planning extreme multi-GPU arrays will need a higher-capacity unit. The Bronze rating means efficiency drops below 80 % at very light loads, so very low-power systems gain less benefit.

Build integration and trade-offs

A temperature-controlled 140 mm fan adjusts speed automatically, keeping noise low while maintaining cooling performance across varying workloads. The flat modular cables simplify routing and reduce air friction, freeing up space for larger coolers or additional case fans. The unit follows the ATX12V and EPS12V standards with Active PFC, fitting standard ATX cases and motherboards. Systems needing specialised form factors, higher wattage or Platinum-class efficiency should look elsewhere.
