ATX Non Modular 600W Power Supply with 120mm Fan - Reliable 12V Output

Our review of the ICESHARKS ATX Non Modular 600W power supply finds it best suited to budget-conscious builders who need a stable, continuous +12V rail and simple, no-frills cooling. The single biggest reason to buy is its dedicated +12V line rated to 45A, which supports sustained loads without the voltage sag often found on lower-quality units. The unit's automatic thermal control 120mm fan and flat linear output also make it an easy drop-in power source for desktop builds that require predictable performance and a long parts warranty.

Key Features

• Automatic thermal control 120mm fan: Keeps internal temperatures lower under varying load by adjusting fan speed, reducing noise during light use and ramping up when the system needs cooling.
• Dedicated +12V line: The +12V@45A rail is designed for continuous use, offering stable power for modern CPUs and GPUs in mainstream systems.
• Flat linear output: Provides steady voltages across rails to reduce the risk of stalls or instability under steady loads.
• Wide input support: 110-220V universal input allows use with common mains voltages without manual switching, useful for users in different regions.
• Comprehensive connectors: Includes 20+4P, 4+4P, two 6+2P PCle, four SATA, four PATA and one FDD connector to cover older drives and common modern peripherals.
• Five-year warranty: Gives longer-term peace of mind for users who want a warranty-backed budget power supply.

Who It's For

The ICESHARKS 600W non modular PSU is a practical choice for first-time PC builders, office workstations, and budget gaming rigs where cable management is moderate and a strong +12V rail matters. It is especially appropriate for systems that will not be heavily overclocked but do require reliable continuous power delivery to the CPU and a single GPU.

It is not the best option for compact mini-ITX builds that demand modular cables to reduce clutter, nor for high-end gaming rigs with multiple GPUs or extreme overclocking where larger capacity, fully modular, high-efficiency units are preferable.

Pros & Cons

Pros

• Strong continuous +12V rail that supports stable operation of modern components.
• Automatic thermal control 120mm fan balances cooling and noise for everyday use.
• Wide selection of connectors handles a mix of SATA and legacy PATA devices without adapters.
• Five-year warranty provides extended coverage compared with many budget supplies.

Cons

• Non modular design increases cable clutter and can complicate builds with tight space requirements.
• No efficiency rating is stated, so efficiency and long-term power draw are not specified in the product information.

Frequently Asked Questions

Does this unit support universal mains voltages?
Yes, it supports 110-220V universal input so it can be used across common mains voltages without manual switching.

How many GPU connectors are provided?
There are two PCle 6+2P connectors, suitable for a single mainstream GPU or light dual-card setups depending on power draw.

Is it modular to improve cable management?
No, this is a non modular ATX power supply, so all cables are fixed to the unit which can increase clutter in small cases.
