1000W Power Supply 80+ Gold Full Modular PSU ES1000 - Stable, Quiet

In this review of the ES1000 1000W Power Supply, the bottom line is straightforward: this unit is aimed at builders who need a high-capacity, efficient power source that stays quiet and keeps cable clutter under control. The reviewer found the core selling point to be the combination of 80 Plus Gold efficiency and a full modular layout, which together deliver clean power and simplified cable management for high-end gaming rigs and workstation builds.

Key Features

• 80 Plus Gold certified: Delivers roughly 90% or higher efficiency under typical loads, which reduces waste heat and can lower electricity costs over time.
• Full modular cables: Lets builders connect only the cables they need to improve airflow and keep the case interior tidy during installation.
• DC to DC design: Provides a more stable and consistent voltage output for sensitive components such as CPUs and GPUs.
• 140mm quiet fan: Maintains cooling with low audible noise, so the system stays quiet even under moderate loads.
• Comprehensive protections: Built-in OVP, UVP, SCP, OPP and OCP help protect the system from common power faults.

Who It's For

The ES1000 is best for PC builders running high-end graphics cards or multi-drive systems who want stable, high-wattage output and a modular harness to keep cable routing simple. It suits gamers using power-hungry GPUs and content creators who need reliable continuous power for demanding workloads.

Those on a strict budget or with very modest power needs should look at lower wattage or less feature-rich units, and anyone needing a fully sleeved custom cable aesthetic from the factory may prefer third-party cable kits or a different model with premium cables included.

Pros & Cons

Pros

• High efficiency from the 80 Plus Gold rating helps keep temperatures and waste energy down.
• Full modular cabling simplifies installation and improves airflow inside the case.
• Quiet 140mm fan operation keeps system noise low during normal use.
• DC to DC architecture and multiple protections promote stable and safe power delivery.

Cons

• Some customers reported mixed long-term reliability, so power longevity may vary between units.
• Included cables are functional but receive mixed feedback on build feel compared with premium aftermarket cables.
