This article covers ASRock PRO 750G 電源.

Overview

The ASRock PRO 750G is a 750W ATX power supply unit certified 80 PLUS Gold, meaning it achieves up to 90% efficiency under typical loads. It fully supports the latest ATX 3.1 and PCIe 5.1 standards, and features a native 12V-2x6 connector that can deliver up to 450W to modern high-end graphics cards. A 120mm low-noise fan keeps things cool and quiet.
Positioned in the mid-range high-value segment, this PSU is ideal for gamers and builders who want modern connectivity without breaking the bank. With a 750W capacity, it comfortably handles setups like a Core i5-13600K paired with an RTX 4070, and the native 12V-2x6 connector eliminates the need for adapter cables. A 3-year warranty adds a layer of reliability.

Compatibility Guide

The ASRock PRO 750G uses the standard ATX form factor, fitting the vast majority of mid-tower and full-tower cases. It provides a 24-pin main power connector, an 8-pin EPS12V CPU connector, PCIe 6+2-pin cables, and the new native 12V-2x6 connector. The 12V-2x6 is backward compatible with existing 12VHPWR cables, so you can use it with RTX 40-series cards or newer models that adopt the updated standard.
750W is sufficient for a mainstream gaming rig: for example, an AMD Ryzen 7 7800X3D (120W) plus an NVIDIA GeForce RTX 4070 (200W) leaves plenty of headroom. However, if you plan to install an RTX 4090 or a heavily overclocked Core i9, you should look at an 850W or higher unit. Always check your case’s PSU clearance (typically >140mm depth), though this unit is a standard 140mm depth.

Product Info

The ASRock PRO 750G launched in late 2025, targeting the value-focused mid-range market. It offers the modern feature set—ATX 3.1, PCIe 5.1, native 12V-2x6—at a price point well below many competitors. The 80 PLUS Gold rating ensures decent efficiency and lower waste heat. It comes with a 3-year warranty and is sold through major Japanese online retailers, where it often retails around ¥15,000.
Key specs include: 750W continuous output, a single +12V rail, active PFC, and a 120mm hydraulic bearing fan that runs quietly at low loads. Cables are flat and easy to route in most cases. While not fully modular (some cables are fixed), the most critical ones (12V-2x6, PCIe, SATA) are detachable, offering a good balance between convenience and cost.

Best Use Cases

  • Mid-range gaming PC builder
    If you’re assembling a system with a Core i5-13600K or Ryzen 5 7600X and an RTX 4070 (or RX 7800 XT), this PSU provides ample power and headroom for future upgrades. The 12V-2x6 connector is future-proof for the next GPU generation. Not recommended for those planning a dual-GPU or RTX 4090 setup.
  • Quiet PC enthusiast on a budget
    The 120mm fan operates silently at low loads, and the Gold efficiency reduces heat output, keeping fan speeds in check. It’s a solid choice for a living room HTPC or quiet office build. If total silence is critical, consider a fanless or semi-fanless design.
  • First-time builder wanting modern standards
    This PSU simplifies cable management with its native 12V-2x6, avoiding awkward adapter pigtails. It’s a great introduction to ATX 3.1 without paying a premium. Avoid if you need extensive modularity (all cables detachable) or longer warranty coverage.
  • Secondary PC or media server
    750W is overkill for a basic office machine, but it offers stability and future reusability. If you plan to recycle this PSU into a gaming build later, it’s a reasonable investment. However, for a low-power server, a smaller 400-500W unit would be more cost-effective.

Things to Consider

While the PRO 750G offers excellent value, there are a few downsides. First, it is not fully modular; the 24-pin and CPU 8-pin cables are permanently attached. This can make cable management in tight cases slightly harder. Second, the 3-year warranty is shorter than the 5-10 years offered by premium brands like Seasonic or Corsair. Third, 750W may be insufficient for high-end power-hungry components, especially the RTX 4090 or 14900K when overclocked. Finally, ASRock is relatively new to the PSU market, so long-term reliability data is limited. Check independent reviews for load regulation and ripple performance.

FAQ

Q: Can I use this PSU with an RTX 4090?
A: It is not recommended. The RTX 4090 can draw over 450W transiently, and the PRO 750G’s single +12V rail may struggle under sustained heavy load. NVIDIA recommends at least 850W for the RTX 4090. A 750W unit is better suited to the RTX 4080 or below.
Q: Does the 12V-2x6 connector work with older RTX 30-series cards?
A: No, RTX 30-series cards use standard 8-pin PCIe connectors. You can use the included 6+2-pin cables to power them. The 12V-2x6 is specifically for cards that have the new 12+4-pin port (RTX 40-series and future models).
Q: Is this PSU compatible with the ASRock B650E Taichi motherboard?
A: Yes, the motherboard uses standard ATX and EPS connectors. The PRO 750G will work witho
