COUGAR ATLAS 550 550W 80 Plus Bronze PSU - CGR-AT550

Cougar ATLAS 550 is an ATX power supply with 550W power and 80+ Bronze certification – right in the sweet spot for budget to mid-range gaming or work machines. It operates on 100 – 240 VAC, so it is perfectly fine for our electrical grid and unstable voltage. With efficiency up to 85% and active PFC, you get more stable power supply for the system and less loss as heat. The format is standard ATX with a length of only 140 mm, which helps in more compact cases.

What you get: enough power for a typical gaming build with one GPU, several drives, and a decent CPU, without worrying about connectors. You have 2 x PCI-Express 6+2 pin, which is sufficient for most modern mid-range graphics cards. The five SATA connectors allow you to connect several SSDs/HDDs plus possibly an optical drive or additional accessory. A 120mm fan takes care of cooling, combining decent airflow with lower noise compared to smaller sizes. The non-modular design means more cables in the case, but in return, you get simpler installation and a lower price.

• Power 550W – completely sufficient for a standard gaming or office/productivity config with one GPU and several storage devices.
• 80+ Bronze certification with up to 85% efficiency – less energy loss, lower heat, and more stable operation under load.
• Active PFC – better power factor correction and more stable power supply during fluctuations in the grid.
• Connectors: 20+4 Pin ATX, 4+4 Pin ATX/EPS, 2 x PCI-Express 6+2 pin, 5 x SATA, 2 x PATA – covers a typical modern build plus some older devices.
• 120mm fan – balanced cooling and lower noise compared to smaller fans with the same airflow.
• ATX format, dimensions 140 x 150 x 86 mm – compatibility with most standard cases and convenience during installation even in more compact chassis.
• Non-modular design – all cables are fixed, simplifying connections and usually lowering the price.

Who it is suitable for: if you are building a budget or mid-range gaming computer with one GPU or a stable office/home PC, this power supply will fully serve you. If you are aiming for high-end configurations with a very powerful GPU and a bunch of additional devices, it’s better to look for a higher wattage and possibly a higher class certification.

The combination of 550W, 80+ Bronze efficiency, and a full set of connectors makes Cougar ATLAS 550 a reasonable and balanced choice for mainstream configurations without paying extra for things you won’t use.
