This article covers 静かに!ストレートパワー12 750W電源.
Overview
The be quiet! Straight Power 12 750W is an ATX 3.0 power supply that achieves 80 PLUS Platinum certification with up to 93.8% efficiency. It features the company's premium Silent Wings fan, which uses fluid-dynamic bearings and a 6-pole motor to minimize noise. The funnel-shaped fan intake reduces turbulence and improves cooling performance. This unit delivers 750W of continuous power on a single +12V rail and can handle transient spikes up to double its rated capacity. It comes with a native 12VHPWR connector for PCIe 5.0 graphics cards, making it a future-proof choice for modern high-end builds.
Compatibility Guide
The Straight Power 12 750W uses the standard ATX form factor, fitting most mid-tower and full-tower cases. It provides one 24-pin main connector, two CPU EPS 12V connectors, four PCIe 6+2-pin connectors, and one 12VHPWR connector. SATA and peripheral connectors are also included for multiple drives and fan hubs. With 750W capacity, this PSU is ideal for single-GPU setups up to the RTX 4080 Super or RX 7900 XT class. For a Core i7-14700K paired with an RTX 4070 Super, it offers plenty of headroom. However, if you plan to use an RTX 4090 or future flagship GPU under full load, consider an 850W or higher unit.
Product Info
Released in mid-2023, the Straight Power 12 750W sits in the upper-midrange segment. It combines 80 PLUS Platinum efficiency with ATX 3.0 compliance and be quiet!'s signature silent operation. The unit comes with a 5-year warranty and features a wireless internal design to improve airflow and component longevity.
Best Use Cases
This PSU is an excellent choice for silent PC enthusiasts. The Silent Wings fan is virtually inaudible at low loads, making it perfect for quiet home offices, media centers, or recording studios. It is also ideal for builders planning to use a PCIe 5.0 graphics card. The native 12VHPWR connector eliminates the need for adapters, simplifying cable management. Finally, users who run their systems 24/7 will benefit from the high efficiency, which reduces electricity costs and heat output over time.
Things to Consider
The 750W capacity is sufficient for most single-GPU builds, but it may be tight for an RTX 4090 or future flagship cards under sustained full load. If you plan to upgrade to such a GPU, stepping up to an 850W model is recommended. Note that this unit is semi-modular: the main 24-pin and CPU EPS cables are hardwired. If you prefer fully modular cabling for the cleanest build, consider the be quiet! Dark Power 13 series. Competitors in this price range include the Seasonic Focus GX-750 and Corsair RM750x. Both are 80 PLUS Gold units with excellent reputations, but the Straight Power 12 offers higher efficiency and native ATX 3.0 support, giving it an edge for future-proofing. ## Alternatives
Direct competitors include the Seasonic Focus GX-750 (80 PLUS Gold, 10-year warranty) and Corsair RM750x (80 PLUS Gold, quiet operation). The Straight Power 12 750W stands out with its 80 PLUS Platinum efficiency and native ATX 3.0 support, making it a better choice for users who prioritize efficiency and future compatibility.
