🥈 Runner-Up

ARESGAME AGV Series 500W Power Supply, 80 Plus Bronze Certified, Non Modular Power Supply, 5 Year Warranty

The ARESGAME AGV 500W offers an 80 Plus Bronze efficiency rating, providing a more stable power curve for the Ryzen 5 5600X and RTX 2070 than white-rated alternatives. Its 500W output is well-suited for this mid-range hardware, offering a balance between thermal performance and power delivery. The inclusion of a 5-year warranty provides a level of longevity assurance that is often missing from ultra-budget power supplies in this specific wattage category.

Strengths
  • 80 Plus Bronze efficiency reduces heat output during gaming sessions
  • Five-year warranty provides better long-term security for your components
  • Adequate 500W capacity supports the RTX 2070's power requirements comfortably
Trade-offs
  • Non-modular design complicates cable management in compact PC builds
  • Component quality is lower compared to tier-one enthusiast power supply brands

450W ATX Power Supply,ESGAMING 450W PC PSU with Auto-Thermally Controlled 120mm Fan, 115/230V Manual Switch, All Protections

This ESGAMING 450W unit features 80 Plus Gold efficiency, making it the most power-efficient option for the Ryzen 5 5600X and RTX 2070 build. While 450W is near the lower limit for this GPU, the high efficiency rating ensures minimal power loss under load. The manual voltage switch is an older design quirk, so users must ensure it is set correctly for their region to avoid potential damage to the system.

Strengths
  • 80 Plus Gold efficiency minimizes power waste and thermal output
  • 450W capacity is perfectly sized for the efficient Ryzen 5 5600X
  • Compact footprint fits easily into smaller ATX enclosures
Trade-offs
  • Manual 115/230V voltage switch requires user attention during initial setup
  • Lower total wattage provides less headroom for future GPU upgrades

⬆️ Upgrade Pick

Thermaltake Smart 500W 80+ White Certified PSU, Continuous Power with 120mm Ultra Quiet Cooling Fan, ATX 12V V2.3/EPS 12V Active PFC Power Supply PS-SPD-0500NPCWUS-W

The Thermaltake Smart 500W provides a modest wattage buffer for your Ryzen 5 5600X and RTX 2070, offering essential headroom for transient spikes that often plague older Turing-based cards. While this 80+ White unit lacks the efficiency of Gold-rated alternatives, its 500W capacity ensures stable operation during aggressive CPU overclocking sessions. This non-modular unit is a budget-conscious choice that prioritizes raw wattage over cable management, providing just enough overhead to support a future mid-range GPU upgrade without requiring a complete system overhaul.

Strengths
  • Provides 50W of additional headroom beyond the 450W baseline for transient spike protection
  • Sufficient capacity to support future GPU upgrades without exceeding the unit's continuous power rating
  • Reliable ATX form factor ensures compatibility with standard mid-tower chassis for the 5600X
Trade-offs
  • Non-modular cabling creates significant clutter in smaller cases, potentially impeding airflow to the GPU
  • 80+ White efficiency rating results in higher thermal output compared to Gold-certified power supplies
