SFX L Quiet Performance Power 600W 80 Plus Gold - Compact PSU

In this review of the SFX L Quiet Performance Power 600W 80 PLUS Gold power supply, the focus is on builders who need a high-efficiency, compact PSU for mini ITX or small form-factor gaming rigs. The single biggest reason to consider it is the combination of 80 Plus Gold efficiency and a modular design that keeps cable clutter minimal while delivering stable power in tight cases. The reviewer found the unit well suited to compact systems that demand reliable, efficient delivery without sacrificing build flexibility.

Key Features

• 80 Plus Gold certification: Delivers up to 92% efficiency under typical loads, reducing waste heat and improving power draw from the wall.
• Modular cables: Allow a cleaner build and easier cable routing in confined mini ITX layouts, improving airflow and aesthetics.
• Multi-GPU support: Four PCIe connectors make the unit compatible with compact builds that use one or two discrete GPUs with additional power needs.
• Advanced conversion topology: Stable LLC, synchronous rectifier and DC-to-DC conversion provide consistent voltages and better transient response for sensitive components.
• 120mm temperature-controlled fan: Keeps noise low under moderate load while ramping as needed to protect components, helping maintain quiet operation in small cases.
• SFX-to-ATX adapter: Includes a bracket for fitment in larger cases where an SFX L form factor needs to be mounted in an ATX bay.

Who It's For

This power supply is ideal for mini ITX builders, compact gaming system owners and anyone prioritizing high efficiency and a modular wiring layout in a small chassis. The 600W rating and four PCIe connectors suit single-GPU gaming PCs and some compact dual-GPU setups where space is at a premium.

It is less appropriate for users who need very long cable runs or those concerned about absolute silence under heavy, sustained loads; several customers reported mixed experiences with cable length and observed fan or electrical noise in a minority of units. Users with very long-reach cases should check cable routing before purchase.

Pros & Cons

Pros

• High efficiency reduces heat and operating cost while improving thermal headroom in small cases.
• Modular cables and compact SFX L size make tidy builds and tight routing straightforward.
• Solid build quality and stable conversion topology provide dependable voltage delivery for modern components.
• Includes an adapter bracket for flexible case compatibility between SFX and ATX mounts.

Cons

• Cable lengths are shorter than some users expect, which can limit routing options in larger or awkward cases.
• Customer feedback on quietness and long-term reliability is mixed, with a few reports of noise or sudden failure.

Frequently Asked Questions

Is this suitable for a small gaming PC?
Yes. The 600W rating and four PCIe connectors make it suitable for most single-GPU compact gaming systems and some tighter dual-GPU configurations when space is limited.

Does it come with an adapter for ATX cases?
Yes. The package includes an SFX-to-ATX adapter bracket to install the PSU in larger case sizes.

Are the cables long enough for full-size cases?
Cable length is modular but relatively short; builders with long routing paths should measure or plan beforehand as some customers found the cables too short.
