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 is a budget-tier unit that technically provides enough headroom for the Intel Core Ultra 5 250K and RTX 4060, but it lacks the efficiency of modern standards. With only 80+ White certification, it wastes more energy as heat compared to Bronze alternatives. While it powers this mid-range build, the non-modular cable mess makes cable management difficult in smaller chassis, and it lacks the premium transient response required for high-end gaming spikes.
- Provides sufficient 500W capacity for the Core Ultra 5 250K and RTX 4060 combo
- Affordable entry price point for budget-constrained system builders
- Standard ATX form factor ensures compatibility with most mid-tower cases
- Basic 80+ White efficiency results in higher power draw and increased thermal output
- Non-modular cabling creates significant clutter in compact PC builds

ARESGAME AGV Series 500W Power Supply, 80 Plus Bronze Certified, Non Modular Power Supply, 5 Year Warranty
The ARESGAME AGV 500W offers a surprisingly high value proposition for a build featuring the Intel Core Ultra 5 250K and RTX 4060. Despite some market confusion regarding its efficiency ratings, it provides a stable power floor for these components. The 5-year warranty is a standout feature in this price bracket, offering more long-term security than the standard 3-year warranties found on entry-level units, making it a practical choice for a balanced gaming rig.
- Five-year warranty provides better long-term protection for your CPU and GPU investment
- Sufficient 500W overhead handles the RTX 4060 power spikes with ease
- Bronze-rated efficiency reduces electricity waste compared to entry-level white units
- Non-modular design complicates cable management in smaller, windowed PC cases
- Brand reputation is less established than legacy tier-one power supply manufacturers

EVGA 100-BR-0450-K1 450 BR, 80+ BRONZE 450W, 3 Year Warranty, Power Supply
The EVGA 450 BR is a reliable, no-frills power supply that perfectly matches the power envelope of the Intel Core Ultra 5 250K and RTX 4060. Its 80+ Bronze certification ensures decent efficiency during typical gaming loads, and the 450W capacity is precisely tuned for this efficient hardware pairing. While it lacks modularity, EVGA's engineering provides consistent voltage regulation that is superior to generic white-label units, making it the safest choice for this specific build.
- 80+ Bronze efficiency is ideal for the power-efficient RTX 4060 and 250K architecture
- EVGA’s reputable build quality ensures stable voltage regulation under gaming loads
- Compact footprint fits easily into virtually any standard ATX or Micro-ATX chassis
- Fixed, non-modular cables require extra space behind the motherboard tray for storage
- Limited 450W ceiling leaves very little room for future high-power GPU upgrades
