This article covers NZXT C1000 Gold v2 Black 1000W ATX3.1対応 80PLUS Gold 認証 PC電源ユニット PA-0G2BB-JP PS1466.

Overview

The NZXT C1000 Gold v2 Black is a 1000W ATX3.1 compliant power supply unit that balances stable output with high conversion efficiency. It carries 80PLUS Gold certification, achieving over 89% efficiency under 20-100% load. The fully modular cable design lets you connect only the cables you need, optimizing airflow inside your PC case.
This unit complies with the latest ATX12V v3.1 standard and comes with a native 12VHPWR connector, making it ready for GeForce RTX 40-series and future high-end GPUs. A 135mm FDB fan operates silently under 50% load, keeping noise to a minimum during everyday use.
High-quality Japanese capacitors extend hold-up time and reduce ripple noise, while the 10-year warranty provides long-term peace of mind.

Compatibility Guide

The form factor is standard ATX (150×160×86mm), fitting most ATX cases. However, the 160mm depth is slightly longer than average, so check clearance in compact or budget cases before purchasing.
Connector configuration:

  • ATX 20+4 pin ×1
  • EPS 8 pin (4+4 pin combo) ×1
  • 12VHPWR (16-pin 12+4) ×1
  • PCIe 6+2 pin ×3
  • SATA ×12
  • Peripheral 4 pin ×4
    With a single 12VHPWR connector, this PSU is ideal for single high-end GPU setups like RTX 4090 or RTX 4080 Super. Note that only one EPS 8-pin cable is included — motherboards requiring two EPS connectors (e.g., high-end X670E/Z790 boards) may need an adapter or additional cable.

Product Info

Released in late 2024, the NZXT C1000 Gold v2 Black carries a street price around ¥24,000 (tax included). It offers competitive value for a 1000W 80PLUS Gold unit. The 10-year warranty is among the longest in its class.
Positioned in the mid-high to high-end segment, its 1000W capacity comfortably handles an RTX 4090 + Ryzen 9 / Core i9 build. ATX3.1 compliance ensures compatibility with next-generation GPU transient spikes.
Protection features include OVP, UVP, SCP, OTP, OPP, and OCP. Operating temperature range is 0-50°C, with an MTTF of 100,000 hours.

Best Use Cases

  • High-end gaming PC builders: If you're pairing an RTX 4090 or RTX 4080 Super with a Ryzen 9 or Core i9, the 1000W headroom and ATX3.1 transient response provide peace of mind. The native 12VHPWR cable eliminates adapter clutter.
  • Silence-oriented enthusiasts: The 135mm FDB fan stops spinning below 50% load (semi-fanless mode). During idle or light gaming, the PSU is effectively silent.
  • Long-term users who don't want to upgrade often: The 10-year warranty and Japanese capacitors promise durability. The 1000W capacity also leaves room for future GPU upgrades.
    On the flip side, this unit is overkill for budget builds or mid-range systems that only need 600-750W. Also, if your motherboard requires dual EPS 8-pin, you'll need to source an extra cable.

Things to Consider

The single EPS 8-pin connector is a notable limitation. Some high-end motherboards (e.g., ASUS ROG CROSSHAIR X670E) require two EPS cables. While a single EPS cable can deliver up to ~336W (12V×28A), which is enough for most CPUs, extreme overclocking or certain server-grade boards may need a second cable.
Cable length is adequate for standard ATX cases, but in full-tower or extra-large cases, some cables (especially SATA) might be tight. The 12 SATA connectors are generous, but routing them neatly requires planning.
Competitors in the same price bracket include the Seasonic Focus GX-1000 and Corsair RM1000e. The NZXT C1000 Gold v2 differentiates with ATX3.1 support and a 10-year warranty, but if you need dual EPS, Seasonic or Corsair may be safer choices.

FAQ

Q: Can this PSU power a future RTX 5090?
A: While unannounced, the ATX3.1 compliance and 12VHPWR connector suggest good compatibility. However, final TDP will determine if 1000W is sufficient — keep an eye on official specs.
Q: Is one EPS 8-pin enough for a Ryzen 9 7950X?
A: Yes, under normal operation. A single EPS 8-pin can deliver up to ~336W, while the 7950X typically draws around 200W under full load. Extreme overclocking (e.g., LN2) may require a second cable.
Q: Are the cables flexible?
A: They are standard sleeved cables — not ultra-soft, but manageable. The fully modular design helps you use only the cables you need, reducing clutter.
