Description

80 Plus Platinum Certification

The Straight Power 12 850W is 80 PLUS Platinum certified with energy efficiency up to 94%. This provides many benefits for your high-end system, including lower power consumption and an overall cooler and quieter operation.

Ensure the Future of Your System

The Straight Power 12 750W is an ATX 3.0 power supply and features both a native 12VHPWR connector for next-generation PCIe 5.0 graphics cards and 4 PCIe 6+2-pin connectors to support current-generation GPUs. This makes the PSU extremely versatile and the ideal choice for today's powerful systems and those to come.

The new type of power

The Straight Power 12 offers 750W of continuous power with a massive 12V rail. Even if the graphics card demands excessive power for a short period: The Straight Power 12 750W handles power surges up to twice its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.

Silent Wings Fan

The high-spec Silent Wings fan provides the best possible airflow in its category but produces minimal noise. This is due to the unique, optimized design of the fan blades along with an advanced bearing and a 6-pole fan motor that greatly eliminates operational noise, has an exceptionally long lifespan, and minimal energy consumption.

Excellent Cooling Performance

The funnel-shaped fan inlet of the Straight Power 12 750W increases airflow while reducing unwanted turbulence for higher cooling performance. The cable-free design inside allows cool air to reach all components, which ultimately leads to a longer lifespan.

Modern Technologies

With full bridge LLC, the Straight Power 12 750W offers advanced technologies, resulting in higher efficiency, better regulation, and lower ripple noise for unparalleled stable operation.

Japanese capacitors 105°

Only top-notch components are used in the Straight Power 12 750W. This is why this power supply exclusively features high-quality Japanese capacitors. They are rated at 105°C for stability, reliability, and long lifespan.

System Protection

Straight Power 12 protects your PC from over-power (OPP), over-voltage (OVP), under-voltage (UVP), over-current (OCP), over-temperature (OTP), and short-circuit (SCP).

Ease and Connectivity

The cables with modular sleeves up to 100 cm in length simplify the installation of components and reduce annoying clutter. This results in increased airflow and improved cooling - even in the largest PC cases.

    Very good power supply but it should have provided another 8pin, I had to get another one! It's not a big deal but it should have had it. At least it should be enough for the GPU

    This review is about the power: 1500 W

    Purchased with a logical futureproof mindset because graphics cards are increasingly demanding crazier numbers.
    Quality sturdy construction.
    Completely silent.
    Includes 2 cables 12+4 pin for next-generation graphics cards.
    I would have preferred the cables to be a bit more flexible, but it doesn't change my overall opinion of the product.

    This review is about the power: 1500 W

    Beast of a power supply, I have the titanium 1500w as well, but this one is literally only 2% less in efficiency (titanium vs platinum) at half the price.

    Full modular, huge power, handles everything and operates without even spinning its fans as it never raises temperature.

    I have it in a computer with a 5950x and an Asus TUF Gaming 3080.

    This review is about the power: 1200 W

    Building a new computer for the next 5 years, I chose the 1200W for 220 Euros, also because I have read the best reviews about the quality of Be Quiet. It powers an RTX3070Ti, an I5 14600K, a Noctua NH-U12A, 10 Phanteks PH-F120D30 Case Fans, an MSI motherboard with 2X16GB (soon another 16GB), and 6 WD SSDs (1 NMVe also coming soon). Opening the box, you can simply see that it is worth the money. The choice was made because a 4080Ti will be installed on the motherboard this Christmas. The rounded sleeved cables greatly help with cable management. Silent and so far without any strange noises.

    This review is about the power: 1200 W

    Very bad power supply, first of all it has 2 connectors for pcie making it unsuitable for high-end graphics cards. Secondly, I noticed fps stutters with 7900xtx and suspected that the power supply was to blame. So out of curiosity, I put in an old one I had and had no problems at all. This company has really fallen in my eyes now...

    This review is about the power: 1200 W

    The power supply is incredibly good and high-quality at its core.
    It operates silently and is very stable in voltage fluctuations (Verified with an external meter).

    The only negative aspect is the fan side, which is made of plastic, resulting in small gaps that produced rattling noises while I was checking for gaps. There are also small gaps in the side walls between the metals.

    Very high quality and quiet. It is expensive but I will probably have it for years and protection is more important than 50 euros over 5+ years.

    I still have it for only a month and I can't say that I have done exhaustive tests on it, but its construction seems flawless, its connections are complete, and it reached the processor's limits without any problem. The 1000W is probably more powerful than I need, but I think it's better to have some margin.
