ASUS Prime 750W Bronze White Edition PSU - PRIME-750B-WHITE
The ASUS Prime 750W Bronze White Edition PSU is a 750-watt power supply designed for all-round PC builds and gaming rigs that need dependable, efficiently regulated power. It carries 80 Plus Bronze certification and a 6-year warranty, making it a straightforward choice for builders who want confirmed efficiency and long-term coverage without overspecifying their power delivery.
Why this product
80 Plus Bronze certified efficiency
Low-ESR electrolytic capacitors and carefully selected components earn this unit 80 Plus Bronze certification, reducing energy waste and keeping internal temperatures in check.
Dual ball bearings rated to 80,000 hours
The 135mm fan uses dual ball bearings with a rated lifespan of up to 80,000 hours — roughly twice that of sleeve bearings — for consistent, low-noise cooling over the long term.
Six-year warranty included
A 6-year warranty is included as standard, giving builders a long coverage window without purchasing additional protection.
Etched cables rated to UL1581 and UL758
The pliable etched cables meet UL1581 flame-test and UL758 certification standards, and they operate at temperatures 50°C below the safety limit when managed inside a case.
DIY-friendly CPU power connector
A distinct clip and unique colour scheme on the 4+4-pin CPU cable simplifies identification and ensures a secure connection to the motherboard CPU power header.
Comprehensive protection suite
Built-in OPP, OVP, UVP, SCP, OCP and OTP protection circuits guard connected components against common electrical faults.
- Total Output750W
- Efficiency Rating80 Plus Bronze
- Form FactorATX12V
- Fan Size135mm dual ball bearing
- Warranty6 years
- PCIe Connectors3 × 8-pin
- SATA Connectors6
- Dimensions150 × 150 × 86 mm
- SKUASU-2294
- EAN4711636055147
- Fits standard ATX12V cases and motherboards using the ATX form factor.
- Includes a 24/20-pin motherboard connector, two 4+4-pin CPU connectors, three 8-pin PCIe connectors, six SATA connectors and three peripheral connectors.
- AC input range of 100–240 V makes it compatible with mains voltages used in most regions worldwide.
- Three 8-pin PCIe connectors support dual-GPU configurations or high-end single GPUs, but builders requiring four or more PCIe connectors will need a higher-connector-count unit.
- Does not include 0dB (fanless/semi-passive) technology — the fan runs continuously.
Best for
- All-round desktop and gaming builds that need 750W of confirmed Bronze-certified output without paying for higher-tier efficiency ratings.
- White-aesthetic builds where a white PSU finish is needed to match a white case or theme.
- Long-term builders who value the 6-year warranty and the 80,000-hour dual ball bearing fan rating for extended system life.
- First-time builders who benefit from the colour-coded, clip-secured 4+4-pin CPU cable and pliable etched cables that simplify installation.
- Builds requiring six SATA devices — the six SATA connectors accommodate storage-heavy configurations without adapters.
Trade-offs
- Noise-sensitive or fanless builds: this unit has no 0dB or semi-passive mode, so the fan runs at all times.
- Efficiency-critical workloads: builders who require 80 Plus Gold, Platinum or Titanium efficiency ratings will need a higher-certified unit.
- Multi-GPU or high-connector-count systems: only three 8-pin PCIe connectors are provided, which limits configurations requiring four or more GPU power plugs.
- Systems exceeding 750W total draw: combined output is rated at 750W and builders with higher-TDP component combinations should size up.
Prime Performance
With 80+ Bronze certification, dual ball fan bearings, etched cables and an 6-year warranty, the ASUS Prime series PSU brings efficient and durable power delivery to reliable performance for the system build.
80 Plus Bronze Certification
Brains and Bronze
The high-quality components used in ASUS Prime power supplies ensure efficient and reliable operation worthy of an 80 PLUS Bronze Certification.
The efficiency also leads to low temperatures within the PSU, facilitating an even quieter acoustic profile.
COOLING
Dual Ball Fan Bearings
2X Longer Lifespan
Dual ball bearings boast an extensive lifespan of up to 80,000 hours, lasting twice as long as sleeve bearings and exceeding even fluid dynamic bearings. This means long-lasting, reliable cooling with minimal noise when you choose the ASUS Prime Bronze series.
135mm Fan Design
The 135mm fan can reduce heat more effectively, making the PSU cooler and less noise.
EXPERIENCE
Etched Cables
Made from a pliable premium material, these etched cables are easily flexible during installation, and they operate at temperatures 50°C lower than the safety limit when routed for cable management.
These cables also meet the rigorous standards of the UL1581 flame test and UL758 certification, helping to ensure a smooth PC DIY experience and exceptional safety.
DIY-friendly CPU Power Connector
Engineered with a distinct clip between the 4+4 pin connectors and a unique color scheme, this CPU power cable simplifies cable identification during installation. The integrated clip helps to ensure a secure and effortless connection to the motherboard's CPU power connector, streamlining the build process and instilling confidence in your PC setup.
