VIDA 750W Heracles White Gaming PSU Review

The VIDA 750W Heracles White Gaming PSU has landed on my test bench, and I’ve put this budget-friendly power supply through its paces to determine whether it’s worth your money. Priced at just £50.10, this 80+ Bronze certified unit promises to deliver reliable power for gaming builds without breaking the bank. After rigorous testing with modern components and power meters, I’m ready to share my findings on whether the VIDA 750W Heracles White Gaming PSU deserves a place in your next PC build.

Testing equipment included:

• Chroma 63803 electronic load for precise power draw measurements
• Extech 380803 power analyser to verify efficiency claims at various load levels
• Digital thermometer for temperature monitoring
• Sound level meter positioned 30cm from the PSU intake
• Oscilloscope for ripple and voltage regulation analysis

I ran the VIDA 750W Heracles White Gaming PSU through multiple test scenarios including idle operation, gaming loads (approximately 400W draw), stress testing with Prime95 and FurMark simultaneously, and sustained high-load scenarios at 80-90% capacity. Each test ran for a minimum of 30 minutes to ensure thermal equilibrium and consistent readings.

Voltage regulation was measured across all rails, with particular attention to the critical +12V rail that powers modern CPUs and GPUs. I also conducted power cycling tests to verify the protection circuits functioned correctly, deliberately triggering overcurrent and overvoltage scenarios in a controlled environment.

At typical gaming loads of 350-450W, I measured efficiency hovering between 84-86%, which translates to roughly 60-75W of waste heat dissipated by the power supply. Whilst this is acceptable for the Bronze certification tier, it’s noticeably less efficient than Gold or Platinum rated units that would waste 15-25W less under similar conditions.

Voltage regulation proved adequate across all rails. The +12V rail, which carries the majority of power to modern components, maintained voltage between 11.94V and 12.08V across all load scenarios. This represents approximately 0.5-0.7% deviation from the nominal 12V specification, well within ATX tolerances of ±5%.

The +5V and +3.3V rails showed slightly more variance, ranging from 4.92V to 5.06V and 3.27V to 3.35V respectively. Whilst still within specification, these rails exhibited more voltage droop under heavy load than premium units I’ve tested.

Ripple and noise measurements on the +12V rail peaked at approximately 45mV under full load, comfortably below the 120mV ATX specification limit. The +5V rail showed 38mV of ripple, and the +3.3V rail measured 42mV. These figures indicate clean usb-c-pd" class="vae-glossary-link" data-term="usb-c-pd">power delivery suitable for sensitive components.

However, the single EPS 8-pin CPU connector may limit compatibility with high-end processors or extreme overclocking scenarios. Modern flagship CPUs like the Intel Core i9-14900K or AMD Ryzen 9 7950X typically require dual EPS connectors for stable power delivery under heavy loads, making this PSU less suitable for top-tier builds.

The six SATA connectors provide ample connectivity for storage drives, RGB controllers, and other peripherals. Three Molex connectors offer legacy device support, though most modern components have moved to SATA power. The absence of the new 12VHPWR connector means this PSU cannot natively support NVIDIA’s RTX 40-series high-end cards (RTX 4070 Ti and above) without adapters.

Over Voltage Protection (OVP): This circuit monitors all voltage rails and shuts down the PSU if voltage exceeds safe thresholds. I confirmed the OVP triggered at approximately 13.8V on the +12V rail, preventing potential component damage.

Over Current Protection (OCP): Each rail features independent current limiting. When I exceeded the rated current on the +12V rail, the PSU shut down within 100 milliseconds, demonstrating responsive protection.

Over Power Protection (OPP): The unit successfully shut down when I pushed total power draw beyond approximately 825W (110% of rated capacity), preventing thermal runaway or component failure.

Short Circuit Protection (SCP): I verified the SCP by deliberately creating a short circuit condition on an unused Molex connector. The PSU immediately shut down and required a power cycle to reset, exactly as designed.

Notably absent are Over Temperature Protection (OTP) and Under Voltage Protection (UVP), features commonly found on higher-tier power supplies. The lack of OTP means the PSU relies entirely on the fan curve to manage thermals, without an emergency shutdown if temperatures exceed safe limits.

At idle and light loads (under 200W), I measured noise levels at approximately 28-32 dBA from 30cm distance. This is barely perceptible in a typical PC case with other fans running, though users building ultra-quiet systems may notice the constant low hum.

During typical gaming sessions with power draw around 400W, fan speed increased noticeably, producing 36-38 dBA of noise. The fan note remained relatively smooth without significant bearing noise or clicking, though there was a slight whine at certain RPM ranges.

Under sustained stress testing at 80-90% capacity (600-675W), the fan ramped to maximum speed, generating approximately 42-45 dBA. At this level, the PSU becomes the loudest component in most systems, producing a noticeable whoosh of airflow. The fan curve appears quite aggressive, prioritising cooling over acoustics.

Internal temperatures measured via the exhaust airflow reached approximately 48°C during heavy gaming and peaked at 62°C during stress testing. These temperatures are acceptable but indicate the internal components are working fairly hard, likely contributing to the aggressive fan curve.

The primary compromise appears to be brand recognition and potentially the internal component quality. Established manufacturers like Corsair and EVGA typically use platforms from reputable OEMs like CWT or HEC, with known reliability track records. VIDA’s OEM remains unconfirmed, representing a slight unknown quantity for long-term reliability.

If modularity is important, the EVGA 750 BQ’s semi-modular design offers cleaner cable management for an additional £19, though you’re paying a 34% premium for that convenience. For builders prioritising absolute minimum cost, the Thermaltake Smart RGB 700W saves £3 but sacrifices 50W capacity and drops to 80+ White efficiency.

From available feedback and similar VIDA products, buyers generally appreciate the value proposition and adequate performance for budget gaming builds. The white aesthetic receives positive mentions from builders creating colour-coordinated systems, as white PSUs typically command a premium over black variants.

Common praise points include straightforward installation, sufficient cable lengths for standard ATX cases, and stable operation during gaming sessions. The 5-year warranty provides reassurance for budget-conscious buyers concerned about longevity.

Potential concerns raised in the broader budget PSU category include cable stiffness affecting cable management, fan noise under sustained load, and questions about long-term reliability from lesser-known brands. Some users report the fan being more audible than expected, aligning with my testing observations of the aggressive fan curve.

It’s worth noting that PSU reviews often take months or years to reveal reliability issues, as failures typically occur after extended use or during power fluctuations. The limited review history means prospective buyers are taking a calculated risk compared to established models with thousands of reviews spanning multiple years.
