This article covers ALIMENTATIONS CORSAIR inférieur à 600ワット CV450 450W ブロンズ CP-9020209-EU.

Overview

The Corsair CV450 is an entry-level 450W power supply unit with 80PLUS Bronze certification. It's widely available through Japanese online retailers, typically priced around ¥24,000 before tax. The unit features a 120mm rifle-bearing fan that remains near-silent under low to moderate loads, making it a great choice for quiet office or home PCs. Its standard ATX form factor ensures compatibility with the vast majority of mid-tower and mini-tower cases.
A single +12V rail design delivers stable power delivery, handling CPU and GPU load transients effectively. Japanese capacitors are used throughout the internal circuitry, which Corsair claims improves long-term reliability and ripple suppression. With 80PLUS Bronze certification, you get 84–85% efficiency at typical loads, which helps keep heat and electricity costs in check without demanding a premium.
The CV450 is clearly positioned as an affordable, reliable foundation for builds that don't require high wattage. It's ideal for office PCs, light gaming rigs, and home servers. The 3-year warranty adds peace of mind for first-time builders and budget-conscious users alike.

Compatibility Guide

The CV450 is a full-size ATX PSU measuring 150mm wide × 140mm deep × 86mm high. It fits most ATX and MicroATX cases with ease, but some Mini-ITX enclosures may require careful cable management due to the non-modular design. The included cables are: one ATX 24-pin, one CPU 4+4-pin, one PCIe 6+2-pin, four SATA power connectors, and three peripheral (Molex) connectors.
With only 450W of total capacity, this unit is suitable for builds with GPUs up to around the RTX 3060 or RX 6600 class. For higher-end cards like the RTX 4060 Ti or RX 7600 XT, a 550W or 650W PSU is strongly recommended. The single CPU power connector (4+4-pin) is enough for mainstream motherboards, but high-end boards requiring dual 8-pin EPS will not be compatible.
Memory and storage compatibility is straightforward — the four SATA connectors can power up to four drives (SSD/HDD/Optical), and M.2 SSDs draw power directly from the motherboard. There are no PCIe Gen5 or 12VHPWR connectors, so it's best suited for older or mid-range GPUs using standard 6+2-pin connections.

Product Info

The Corsair CV450 was released in 2019 and has maintained a strong reputation for value and reliability in the entry-level segment. Its market positioning is definitively entry-tier: offering a trusted brand, solid build quality, and quiet operation for systems that don't demand high power output. The 80PLUS Bronze certification ensures decent efficiency, while Japanese capacitors and a 120mm fan suggest above-average longevity for the price bracket.
Key specifications include a single +12V rail rated at 37A (444W), a 120mm rifle-bearing fan, and a rated MTBF of 100,000 hours. The unit is non-modular, which keeps costs down but requires some cable management. The warranty is 3 years — shorter than some competitors' 5- or 7-year terms, but still appropriate for the price.

Best Use Cases

  • Office and home productivity PC — Perfect for builds with a Core i3/i5 or Ryzen 3/5 CPU and integrated graphics. The CV450 provides ample power for web browsing, office apps, and media playback while keeping noise to a minimum. Users planning to add a discrete GPU later should verify capacity: a low-power card like the GTX 1650 works fine, but anything more demanding may require a larger PSU.
  • Budget gaming rig — Ideal for first-time builders pairing a Ryzen 5 or Core i5 with an RTX 3050 or RX 6400/6500 XT. The 450W capacity and single PCIe 6+2-pin cable are sufficient for these cards. However, if you're aiming for an RTX 3060 or higher, consider spending a bit more for a 500–550W unit to ensure reliable performance and headroom.
  • Home server or NAS — The combination of low power draw, quiet fan, and high reliability makes the CV450 a solid choice for a low-power file server or media server. With a low-TDP CPU and only a few drives, the unit will run efficiently and quietly 24/7. For systems with 4+ hard drives, ensure total +12V current stays below 37A.
  • Budget secondary or test bench — For a second PC dedicated to light tasks, or a test bench for swapping parts, the CV450's low cost and reliability are valuable. The non-modular cables aren't a big issue in an open-air test bench. Just remember that high-wattage GPUs or multi-GPU setups are out of the question.

Things to Consider

The most critical limitation is the 450W capacity. It's insufficient for mid-range GPUs like the RTX 3060 Ti or RX 6700 XT; these cards alone can draw 200–250W, leaving little headroom for the CPU and other components. A shutdown under heavy gaming load is a real risk with such cards.
Being non-modular, all cables are permanently attached. This makes cable management in small cases more challenging, as you'll need to stow unused SATA/Molex cabl
