Is the 600W Cougar VTE power supply sufficient for a computer with an Intel Core i5-13400F processor and an NVIDIA RTX 5070 graphics card?
The Cougar VTE 600W Power Supply: A Minimally Acceptable Option for i5-13400F and RTX 5070
The Cougar VTE 600W power supply is a minimally acceptable option for a computer with an Intel Core i5-13400F processor and NVIDIA RTX 5070 graphics card, but it leaves very little power headroom and may be insufficient under maximum loads or with additional components.

Power Calculation
The Intel Core i5-13400F has a base TDP (PL1) of 65W for sustained workloads, but can briefly consume up to 148W (PL2) at maximum performance. According to one source, during a Cinebench R23 stress test, the multi-core mode showed consumption of up to 218.9W.
The NVIDIA RTX 5070 has an official TDP of 250W for maximum power. According to TechPowerUp, the graphics card uses a single 16-pin power connector and has a maximum power consumption of 250W.
Additional system components (motherboard, RAM, storage, cooling) typically consume another 50-100W.
Thus, the base power consumption of the system is approximately 365-415W, and under peak loads, it can reach 498W.
Cougar VTE 600W Analysis
The Cougar VTE 600W is a budget power supply with basic specifications. Key points that make it unsuitable for this configuration:
-
Minimal power headroom: Under base load, the system consumes about 60-70% of the PSU’s rated power, which is at the upper limit of the comfortable zone.
-
Peak load issues: As noted in research, the RTX 5070 is prone to significant power spikes that can trigger protection mechanisms or cause unstable operation.
-
Component quality: Budget power supplies often have less stable output voltage and less headroom for peak loads.
-
No future headroom: When adding new components or upgrading the system, there may not be enough power.
PSU Recommendations
For stable operation of a system with i5-13400F and RTX 5070, it is recommended to use a power supply with 700-750W capacity with 30-40% headroom. Ideal specifications:
- Power: 700-750W 80+ Bronze or higher
- Quality: Reputable brands (Corsair, Seasonic, be quiet!, EVGA)
- Cables: Availability of 16-pin connector for RTX 5070
- Protection: Over Power Protection, Short Circuit Protection
Alternative Solutions
If budget is limited, there are several options:
-
Lower requirements: Consider a less powerful graphics card (e.g., RTX 4060 with ~160W TDP) or a processor with lower power consumption.
-
Find a higher quality 600W PSU: Some premium 600W power supplies might handle it, but this is risky.
-
System upgrade: Installing more energy-efficient components (SSD instead of HDD, cooling optimization).
-
Wait for price drops: More efficient components with lower power consumption may become available in the future.
Conclusion
-
The Cougar VTE 600W can work with i5-13400F and RTX 5070, but with a high risk of instability under maximum loads.
-
The optimal choice is a 700-750W power supply from a well-known manufacturer.
-
Beware of peak loads - modern graphics cards can significantly exceed their TDP for short periods.
-
Power headroom is important - it ensures system stability and allows for future upgrades.
-
Quality is more important than power - even a powerful power supply from an unknown brand can be worse than a quality 600W solution from a trusted manufacturer.
