Overview

The EVGA 500 W1 is an ATX power supply built for budget-conscious PC builders who need reliable, no-frills power delivery. Its 500 watts of continuous output handles everyday computing, office workstations, and mid-range gaming rigs that pair a modern processor with a single graphics card of moderate power draw. The 80+ White certification guarantees at least 80% efficiency under typical loads, which translates to less wasted electricity and lower heat output compared to uncertified units, though it falls short of the efficiency levels offered by Bronze, Gold, or Platinum-rated supplies.

Where the 500 W1 sets itself apart in the budget segment is its comprehensive protection suite. OVP, UVP, OCP, OPP, and SCP work together to shield connected components from voltage spikes, current surges, and short circuits — protections that some competing budget PSUs omit to cut costs. The non-modular cable design keeps the price low, and while managing unused cables requires some attention during installation, the trade-off is straightforward for builders prioritizing value over cable aesthetics. An ultra-quiet fan provides active cooling across all load levels to maintain stable thermals during operation.

Pros & Cons

👍 Pros

  • Five heavy-duty protections (OVP, UVP, OCP, OPP, SCP) guard against electrical faults
  • 80+ White certification delivers at least 80% efficiency under typical loads
  • Competitive price point makes it accessible for budget and entry-level PC builds
  • ATX form factor with a 24-pin connector fits standard mid-tower and full-tower cases

👎 Cons

  • Non-modular design means all cables are permanently attached, creating clutter in smaller cases
  • 80+ White is the lowest efficiency tier, producing more heat than Bronze or higher-rated units
  • 500W capacity limits upgrade headroom for power-hungry GPUs or multi-drive configurations
  • No semi-passive fan mode, so the fan runs continuously even at low loads

Frequently Asked Questions

It includes over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), over-power protection (OPP), and short-circuit protection (SCP) to safeguard your components.
The 500 W1 is a non-modular power supply, meaning all cables are permanently attached. This keeps costs down but means unused cables must be managed inside the case.
It means the power supply operates at 80% efficiency or higher under typical loads, reducing wasted energy as heat compared to non-certified units.
500W is sufficient for mid-range builds with a single GPU that has modest power requirements. High-end graphics cards with large power draws will require a higher-wattage unit.
