OEM 80 PLUS Power Supply Manufacturer for Global PC Brands
When your brand sells thousands of gaming or office PCs every month, one unstable Power Supply can destroy years of reputation.
Are your current Psu suppliers truly delivering real 80 PLUS performance, or just printing labels?

From “80 PLUS Tier” to “Operational Cost Savings”
A label is easy. Real efficiency is measurable.
We manufacture power supplies across multiple wattage and certification tiers:
Wattage Coverage
- 500W–700W (Mainstream Gaming Segment)
- 701W–900W (High-Performance Systems)
- 901W–1000W+ (Workstation & Heavy Load Systems)
80 PLUS Certification Options
- 80 PLUS White
- 80 PLUS Bronze
- 80 PLUS Silver
- 80 PLUS Gold
For example:
650W 80 PLUS Gold Full Modular PSU
- Efficiency: up to 87–90%
- Connectors: 20+4Pin ATX, 8Pin EPS, 6+2Pin PCIe, SATA, MOLEX
- Optional 12VHPWR support (ATX 3.0 ready)
- Full protection: OVP / OCP / OPP / SCP / OTP / UVP
What does this mean for B2B buyers?
- Lower RMA rate
- Reduced electricity cost claims from end users
- Stronger retail positioning
- Compliance confidence in EU and North America
Efficiency is not just a spec. It is margin protection.
From “Protection Circuits” to “System Safety Guarantee”
Many brands come to us after experiencing:
- Claimed 80 PLUS Gold, tested as Bronze
- Fan noise complaints under 50% load
- Cable incompatibility with new GPUs
- Reddit and Amazon negative reviews
We prevent these issues before shipment.
Every PSU batch goes through:
- Load simulation testing
- Voltage stability testing
- Thermal performance validation
- Reliability stress tests
Our built-in safety protections include:
- OVP (Over Voltage Protection)
- OCP (Over Current Protection)
- OPP (Over Power Protection)
- SCP (Short Circuit Protection)
- OTP (Over Temperature Protection)
- UVP (Under Voltage Protection)
For distributors and PC brands, this means predictable performance, not unpredictable warranty cost.
From “Modular Design” to “Cable Management Satisfaction”
We offer:
- Non-Modular
- Semi-Modular
- Full Modular
Modular design is not only about aesthetics.
It impacts:
- Assembly efficiency for system integrators
- Airflow performance inside cases
- SKU tier differentiation
- User upgrade flexibility
We also support:
- Custom cable length (1m / 1.2m / 1.5m)
- Sleeved cable options
- Black / White / Custom color housing
This flexibility allows brands to build entry-level Bronze series and premium Gold series with clear pricing ladders.
Factory-Direct Solutions Eliminating Supply Chain Uncertainties
Working with multiple suppliers often leads to:
- Uncontrolled price fluctuations
- Certification confusion
- Lead time inconsistency
At DUNAO, power supplies can be coordinated together with:
- PC cases (ATX / Micro ATX / Mini ITX support)
- Cooling fans (120mm / 140mm RGB options)
- Motherboards
- Graphics cards
This one-stop sourcing reduces coordination cost and improves batch consistency.
For distributors and SI partners, this creates stronger margin control.
