EVO LABS BR500-12BL 500W ATX PSU - 120mm Silent Fan, PFC

The EVO LABS BR500-12BL 500W ATX PSU is a budget-friendly desktop power supply suited to builders putting together or upgrading a standard ATX desktop PC. It delivers 500W of power through a broad set of connectors, while its 120mm silent fan and PFC circuitry keep noise low and power draw efficient.

• 120mm silent fan for quiet operation — The 120mm black fan is rated below 17 dBA, keeping the unit quiet during everyday desktop use.
• Power Factor Control included — Built-in PFC (Power Factor Control) reduces wasted power draw from the mains, which is a practical efficiency benefit for a PSU in this class.
• Broad connector set for standard builds — Ships with a 20+4 Pin ATX connector, a 4 Pin CPU connector, 3 SATA, 2 Molex and 1 FDD — covering most components in a typical ATX desktop build.
• Switchable input voltage — Input voltage can be switched between 115 V and 230 V, making it usable in both UK and North American mains environments.
• CE and RoHS certified — Carries CE and RoHS certifications, meeting standard European regulatory requirements for electronics.
• 100,000-hour MTBF rating — The stated Mean Time Between Failures figure of 100,000 hours indicates the intended longevity target for this unit.

• ✓ Fits standard ATX desktop cases — dimensions are 150 x 85 x 140 mm, which matches the ATX PSU form factor.
• ✓ Compatible with ATX 12V mainboards and most modern CPUs via the included 4 Pin CPU connector.
• ✓ Supports ATX standard versions 2.2 and 2.3, covering a wide range of motherboard generations.
• ✓ Works with up to 3 SATA drives (e.g. SSDs or HDDs) and 2 Molex devices directly from the included cables.
• Note: Input voltage must be manually switched between 115 V and 230 V — selecting the wrong setting before powering on can damage the unit.
• ✗ Does not include a PCIe connector, so it is not suitable for systems using a dedicated graphics card that requires a direct PSU cable.

Best for:

• Basic ATX desktop builds — 500W and a full set of standard connectors covers office PCs, home desktops and entry-level builds without a dedicated GPU power requirement.
• Noise-sensitive environments — the sub-17 dBA fan rating makes it appropriate for living room or quiet office use.
• Multi-drive storage systems — with 3 SATA and 2 Molex connectors, it suits builds that include several hard drives or optical drives.
• Dual-voltage environments — the switchable 115/230 V input makes it usable in both UK and US mains setups.

Trade-offs:

• Gaming or workstation builds with a discrete GPU — no PCIe power connector is included, which rules out most dedicated graphics cards.
• Builds needing more than 3 SATA connections — only 3 SATA connectors are provided; larger storage arrays would require a different unit.
• High-wattage system builds — at 500W total output, it is not suited to power-hungry CPUs paired with multiple components drawing heavy current.
• SFX or small-form-factor cases — at 150 x 85 x 140 mm this is an ATX-sized unit and will not fit SFX or TFX PSU bays.
