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 covers the power requirements for an Intel Core i5-14400 and RTX 5060 pairing. While it lacks the efficiency of 80 Plus Bronze or Gold units, its 500W capacity provides sufficient overhead for these mid-range components. However, the non-modular design and basic 80+ White certification make it a strictly entry-level choice for builders prioritizing absolute lowest upfront cost over long-term electrical efficiency or cable management.
- Provides sufficient 500W capacity for the i5-14400 and RTX 5060
- Extremely low price point for budget-constrained system builds
- Standard ATX form factor ensures compatibility with most budget cases
- Basic 80+ White efficiency results in higher heat and power waste
- Non-modular cabling creates significant clutter in small form factor builds

ARESGAME AGV Series 500W Power Supply, 80 Plus Bronze Certified, Non Modular Power Supply, 5 Year Warranty
The ARESGAME AGV 500W offers a step up in efficiency with its 80 Plus Bronze rating, providing better power conversion for the i5-14400 and RTX 5060. This unit balances the power draw of the 14th Gen Intel architecture with a more stable voltage regulation profile than white-label alternatives. With a 5-year warranty, it offers a reasonable middle ground for users who need reliable power delivery without the premium cost of modular, high-efficiency enthusiast power supplies.
- 80 Plus Bronze certification improves efficiency over entry-level white units
- Five-year warranty provides better peace of mind for mid-range builds
- Adequate wattage headroom for the i5-14400 and RTX 5060 combination
- Non-modular design complicates cable management in compact chassis layouts
- Lacks the advanced transient response handling found in premium ATX 3.0 units

450W ATX Power Supply Non Modular PSU with 6+2 Pin PCI-E Connectors Auto-Thermally Controlled 120mm Fan, 115/220V Switch
This 450W 80 Plus Gold unit is an efficient choice for the i5-14400 and RTX 5060, as these components are highly power-efficient under load. The Gold rating ensures minimal energy waste during operation, keeping thermals lower within the case. While 450W is tighter than a 500W unit, it remains perfectly adequate for this specific hardware stack, provided the user does not plan on aggressive overclocking or significant future component upgrades.
- 80 Plus Gold efficiency minimizes heat output for the build
- Compact 450W rating is perfectly sized for the i5-14400 and RTX 5060
- Auto-thermally controlled fan keeps noise levels low during standard operation
- Manual voltage switch requires user attention during initial system setup
- Non-modular cabling makes routing difficult in cases with limited space

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 budget-conscious power floor for the Intel Core i5-14400 and NVIDIA GeForce RTX 5060, offering a slight wattage buffer over the 450W baseline. While it lacks modern modular cabling and high-efficiency 80+ Gold certification, its 500W capacity handles the RTX 5060's transient spikes with sufficient overhead for future component swaps. This non-modular unit is a utilitarian choice for builders prioritizing low upfront costs over cable management flexibility or premium energy efficiency.
- Provides 50W of extra headroom for future GPU upgrades beyond the RTX 5060
- Sufficient continuous power capacity to stabilize transient spikes from the i5-14400 and GPU
- Cost-effective entry point for budget-constrained builds requiring reliable ATX 12V power delivery
- Non-modular design results in excess cable clutter within smaller PC chassis
- Basic 80+ White efficiency rating leads to higher heat output compared to Gold-rated units
