FAQs
Is the DeepCool PS850G suitable for small-form-factor (SFF) builds?
Yes. The PS850G is designed specifically for compact systems, measuring only 125 × 100 × 63.5mm. It complies with both SFX12V V4.1 and ATX12V V3.1 standards, making it compatible with most small-form-factor cases.
What does Cybenetics Platinum certification mean?
Cybenetics Platinum is an independent efficiency certification that verifies the power supply operates at ≥90% efficiency under typical loads. This means less energy waste, lower electricity bills, and reduced heat output compared to standard supplies.
Why are Japanese electrolytic capacitors important?
Japanese electrolytic capacitors offer superior quality, longer operational life, and better performance stability compared to standard alternatives. They contribute to improved reliability and longevity of the power supply.
What is Fluid Dynamic Bearing (FDB) technology?
FDB uses a thin fluid film to support the fan shaft, resulting in smoother, quieter operation and reduced wear compared to sleeve or ball bearings. This extends fan lifespan and minimises noise in your system.
What protection does the PS850G provide?
The unit includes eight protection circuits: Overvoltage (OVP), Overcurrent (OCP), Short Circuit (SCP), Overtemperature (OTP), Overpowering (OPP), Undervoltage (UVP), Soft-Start (SIP), and No-Load (NLO) protection to safeguard connected components.
What is the warranty period?
The DeepCool PS850G comes with a 5-year manufacturer warranty, backed by a 100,000-hour MTBF rating for reliable long-term operation.
Can the PS850G handle high-performance gaming systems?
Yes. With 850W output and Cybenetics Platinum efficiency, the PS850G is capable of powering demanding gaming and workstation builds while maintaining stable, clean power delivery and thermal management.
