EVGA 500 W3 500W 80+ White Power Supply

The EVGA 500 W3 is a non-modular ATX power supply rated at 500W continuous output with 80+ White efficiency certification. The 80+ White designation means the unit has been independently verified to convert at least 80% of AC input to DC output at three load points — a meaningful floor that separates it from uncertified bargain units that may struggle to deliver rated wattage reliably under sustained load. At 500W, this PSU covers the power budget for a mainstream build: a 65W TDP processor, 16–32GB of DDR4, a mid-range GPU drawing 150–200W, storage, and case fans all sit comfortably within its headroom. The non-modular cable configuration keeps manufacturing cost down but requires careful cable routing in smaller mid-towers and mini-ITX enclosures.

The 500 W3 is positioned at the entry-level of EVGA's PSU lineup and is best suited to first-time builders or budget-focused upgrades where the GPU TDP does not exceed the mid-tier range. It is not the right choice for builds targeting high-end discrete graphics — a system pairing an RTX 4070 or better with a modern 12th/13th Gen Intel or Ryzen 7000 CPU will benefit from a 650–750W 80+ Gold unit instead. For an office PC, HTPC, or a gaming rig built around a mainstream GPU, the 500 W3 delivers reliable, stable power with a warranty that covers the most likely failure window for any PSU. The 3-year coverage is a practical differentiator at this price point.
