This article covers CORSAIR SF750 (2024) 完全モジュラー 低ノイズ 80 プラス プラチナ ATX 電源.

Overview

The CORSAIR SF750 (2024) is a 750W SFX power supply unit with 80 PLUS Platinum certification, designed specifically for small form factor (SFF) PC builds. Despite its compact 100mm depth, it delivers enough juice to handle a high-end gaming rig with an RTX 4070 SUPER or similar GPU. This unit fully complies with Intel ATX 3.0 and includes a native 12VHPWR (PCIe 5.0) connector, making it a perfect match for modern GeForce RTX 40-series cards without needing adapter cables. The fully modular design uses CORSAIR's Type 5 Micro-Fit connectors, which are noticeably smaller and more flexible than standard connectors—a huge advantage when routing cables in tight spaces. Inside, a 92mm fluid dynamic bearing fan provides quiet cooling, and a zero-RPM mode stops the fan entirely under low loads. CORSAIR uses only 105°C-rated Japanese capacitors for long-term reliability, backed by a 7-year warranty. If you're building a compact powerhouse, this PSU deserves a close look.

Compatibility Guide

Form Factor: SFX (100mm depth). An SFX-to-ATX bracket is included for mounting in standard ATX cases. Motherboard Support: Works with any ATX, Micro-ATX, or Mini-ITX board. No socket or chipset restrictions. GPU Support: One native 12VHPWR (PCIe 5.0) connector, plus two standard 6+2 pin PCIe cables. Ideal for single-GPU setups up to RTX 4070 Ti SUPER class. Cable Length: SFX-standard cable lengths. In very large tower cases, the CPU 8-pin cable may be too short—measure your case's PSU-to-CPU distance before buying. * PSU Wattage Guidance: 750W is sufficient for mid-range builds (e.g., Ryzen 7 + RTX 4070). For flagship GPUs (RTX 4090) or high-core-count CPUs (Core i9), consider an 850W+ unit.

Product Info

Released in 2024, the CORSAIR SF750 (2024) sits in the upper-mid-range tier of SFX power supplies. It offers 80 PLUS Platinum efficiency (up to 92%) and a single +12V rail rated at 62.5A (750W). Release Date: 2024 Pricing: Approximately ¥31,000–¥32,000 in Japan ( reference) Warranty: 7 years Key Features: 92mm FDB fan, zero-RPM mode, 105°C Japanese capacitors, fully modular (Type 5 Micro-Fit), ATX 3.0 compliant, PCIe 5.0 12VHPWR connector * Market Position: High-end SFF PSU—ideal for compact gaming or workstation builds where space is at a premium but performance cannot be compromised.

Best Use Cases

SFF Gaming PC Builder: Perfect for Mini-ITX cases like the Cooler Master NR200 or Fractal Design Terra. 750W comfortably handles an RTX 4070 SUPER or RX 7800 XT. Silence-Focused User: Zero-RPM mode means the fan stays off during light loads (web browsing, office work). The FDB fan is also very quiet under load. Cable Management Enthusiast: Type 5 Micro-Fit cables are thinner and more pliable than standard PSU cables, making routing in small cases much easier. Who Should NOT Buy: Anyone planning a dual-GPU setup or a flagship build with RTX 4090 + Core i9-14900K. For those, step up to an 850W+ SFX-L or ATX unit. ## Alternatives
SilverStone SST-SX750-PT: A direct competitor with similar specs (SFX, 750W, Platinum). The CORSAIR edges ahead with its native 12VHPWR connector and slightly more flexible Type 5 cables. SilverStone's unit is often a bit cheaper, but the CORSAIR offers better cable management in tight spaces. Cooler Master V750 SFX Gold: Gold-rated and usually ¥3,000–¥5,000 cheaper. However, the CORSAIR's Platinum efficiency means less heat and potentially lower electricity bills over time. If your budget is tight, the Cooler Master is a solid alternative; if you value efficiency and premium build quality, the CORSAIR is the better pick.

Things to Consider

Power Headroom: 750W is ample for mid-range builds but may be borderline for RTX 4090 or RX 7900 XTX under transient spikes. If you plan to upgrade to a flagship GPU later, consider an 850W+ unit. Cable Length: SFX-standard cables are shorter than ATX cables. In large tower cases, the CPU 8-pin cable may not reach. Always check your case's PSU-to-CPU distance. Single 12VHPWR Connector: Only one native 12VHPWR port is available. Multi-GPU setups are not supported. Case Clearance: Some ultra-compact cases (e.g., Velka 3) accept only SFX units up to 100mm depth—this unit fits, but double-check your case specs. ## FAQ Q: Can I use this PSU with an RTX 5070? A: Yes. The RTX 5070 is expected to have a TDP around 250W, and 750W provides plenty of headroom. The native 12VHPWR connector means no adapter is needed. Q: Is the fan always spinning? A: No. The SF750 (2024) features a zero-RPM mode that keeps the fan off under low to moderate loads (typically below 40–50% load). This makes it virtually silent during everyday use. Q: How long is the warranty? A: CORSAIR offers a 7-year warranty on this unit. Combined with the use of 105°C Japanese capacitors, it's built to last through multiple build cycles.
