Outdated Product
A low-noise and at the same time relatively inexpensive power supply that guarantees high-quality power supply to a computer system. This model is provided with a fan with a hydrodynamic bearing, which allows the device to operate reliably and quietly for many years in the most heavily loaded operating modes. The effectiveness of the model is due to the presence of a certificate 80+. Thanks to this, the Deepcool PF PF550 computer power supply will be able to provide a stable output voltage without high heat. This is a very economical model that allows you to make the power supply of a computer system as energy efficient as possible. The device provides convenient and reliable wires in the form of flat loops. The presence of several PCI-E 6 + 2 pin connectors makes it possible to use the po...wer supply in gaming computers with a good level of performance. A 20+4 pin interface is used to power the system board. The CPU is connected with a 4+4 pin connector. Power at the level of 550 W will allow the device to provide reliable and productive work of a well-balanced computer system.

How to choose a power supply for a PCBasics of choosing a reliable and balanced power supply for your home, office and gaming computer
A well-balanced power supply for a mid-range home PC.
22 December 2025 
Purchased the Deepcool PF750 for a home build with a mid-range graphics card and a processor for everyday use. The 750W power provides ample headroom even when connecting multiple drives and peripherals. The case is simple, with no extra design elements, but it looks neat and reliable. The 120mm fan operates quietly, and the efficient cooling system dissipates heat well even under load. The power supply is non-modular — all cables are attached from the start. For compact cases, this may require careful cable management, but for a standard build, it's not an issue. It has connectors for the motherboard, CPU, graphics cards, and drives (SATA and Molex), which are quite sufficient for most home systems. Energy efficiency is 80 PLUS certified and is approximately 85%, which is a good figure for the budget segment. During use, the PSU demonstrated stable performance: no voltage drops or unpleasant noises even at peak load.
- sufficient power for an average system
- quiet fan operation
- standard connectors for all components
- good energy efficiency
- ease of installation
- cables are not modular, which makes it difficult to install in a small case

Simple BZ. It stands accordingly in a not difficult system, which it copes with without complaints.

None for this price (there was a problem with the wires, but this is not a modular, budget battery, so it's a sin to complain).
