Specifications side by side

How to choose the right one

1. Check efficiency ratings

   Look at the 80 Plus certification to understand energy usage. The NZXT C1500 offers an 80 Plus Platinum rating, which means higher efficiency than standard models. This reduces wasted heat and electricity costs over time. The C1000 and C1200 carry the Gold rating, which is still excellent for most gamers. Higher ratings ensure the power supply converts AC to DC power more effectively. Choose Platinum if you want maximum efficiency for high-end builds. Gold is a solid balance of performance and value for standard gaming rigs.

2. Verify ATX versions

   Ensure the unit supports your motherboard and GPU standards. The C1500 and C1200 both support the ATX 3.1 standard. This version includes native support for modern connectors like the 12V-2x6. This connector is essential for newer NVIDIA and AMD graphics cards. The C1000 does not list ATX 3.1 support in its attributes. If you are building a system with the latest GPUs, prioritize the ATX 3.1 models. This ensures compatibility without needing messy adapter cables for power delivery.

3. Assess modularity needs

   All three listed units are fully modular. This means you can connect only the cables you actually need. This feature helps with cable management and airflow inside your case. Loose cables can obstruct fans and reduce cooling efficiency. Fully modular designs allow you to route cables cleanly behind the motherboard tray. This is particularly useful for glass-sided cases where aesthetics matter. Since all options here offer this feature, you do not need to compromise on cable management regardless of your wattage choice.

4. Match wattage to GPU

   Select a wattage that exceeds your components' peak power draw. The C1500 provides 1500W, which is ideal for extreme high-end gaming builds. It offers significant headroom for future upgrades or overclocking. The C1200 offers 1200W, which is suitable for powerful RTX 40 series setups. The C1000 provides 1000W, which is sufficient for most standard gaming PCs. Do not underspecify your power supply. A higher wattage rating ensures stability under heavy loads and extends the lifespan of your components.

5. Consider physical size

   Check the dimensions to ensure the PSU fits your case. The C1000 has a compact length of 4 inches. This makes it ideal for small form factor cases or tight builds. The C1500 and C1200 are longer, measuring 7.09 and 6.3 inches respectively. Longer units may not fit in smaller chassis. Measure your case's PSU compartment before purchasing. The 4-inch length of the C1000 provides a distinct advantage for compact gaming rigs where space is limited.
