Relative performance estimate
TweakGearPro anchors the psu category to its flagship (highest tier) and expresses NZXT C1000 as an estimated percentage of that flagship, derived from the relative-performance index (tier 0–100). Planning estimate, not a benchmark.
| PSU (nearby tier) | Tier /100 | Est. relative perf. |
|---|---|---|
| Thermaltake Toughpower GF3 1350W | 95 | 100% |
| Corsair HX1200 | 90 | 95% |
| EVGA SuperNOVA 1300 G2 | 89 | 94% |
| Seasonic PRIME TX-1000 | 88 | 93% |
| ASUS ROG Thor 1000P | 86 | 91% |
| Super Flower LEADEX V Platinum 1000W | 85 | 89% |
| be quiet! Dark Power 13 1000W | 84 | 88% |
Method: relative performance % = (part tier ÷ flagship tier) × 100, using the TweakGearPro tier index built from public benchmark / spec-class data. Source: vendor datasheets / TechPowerUp database, retrieved 2026-08-29. Real-world performance varies by workload, drivers and cooling.
Build compatibility & pairing guidance
Practical build notes derived from this part's dataset fields and TweakGearPro reference constants. Planning guidance, not purchase advice.
| Form factor | ATX — SFX units need an SFX case or bracket; ATX will not fit SFF cases. |
|---|---|
| Connectors | ATX 3.1 native 12VHPWR for RTX 40/50. Confirm the 8-pin / 12VHPWR count covers your GPU. |
| Case clearance | Check PSU bay length (usually ≤ 160–180 mm for ATX, ≤ 130 mm for SFX-L). |
| System budget | Plan the rest of the build with the PSU Wattage Calculator and Power Draw Estimator. |
Reference constants (PSU headroom 20%, safe CPU/GPU ceiling 90°C) from the TweakGearPro PC reference dataset, retrieved 2026-08-29. Adapter/case clearance and exact board power vary by model — verify with vendor datasheets.
Optimize your psu
Run your PSU in its 50–70% load sweet spot for best efficiency, keep the intake clear, and size the whole build before buying. Transient GPU spikes reward a quality 80 PLUS Gold+ unit.

How this page's estimates are computed
The relative-performance percentage anchors the category flagship (highest tier) at 100 and scales each part by its tier ratio. The estimated system PSU adds a base system overhead to the part's TDP and applies a 20% headroom from the reference dataset, rounded to a common PSU rating. The tuning sheet estimates load temperature from TDP, cooling class and case airflow, then suggests a voltage offset and expected clock delta — always confirm with a stress test. The LLM planner converts model parameters and quantization to an approximate VRAM footprint (weights + KV-cache) and divides by the card's usable VRAM to suggest a card count. None of these outputs are benchmark guarantees. For non-CPU/GPU parts the tier reflects the part's spec class relative to the best current model in that category.
