Best UPS for PC

The FrimeCom VP-1200 uninterruptible power supply surprises with its affordable price, which includes two 9 Ah batteries at once. You can immediately note the accompanying heavy weight of 9.5 kg. The UPS provides longer autonomy when the main power supply is turned off, even under increased loads. The rated output power of 720 W allows you to connect not only budget home or office PCs, but also entry-level gaming machines with a consumption of more than 500 W. The presence of only three sockets with a reserve (type F - euro) is a little disappointing. A good power reserve involves connecting secondary equipment (speakers, router, chargers), but this will require additional extension cords.

FrimeCom VP-1200 does not produce a pure sine wave, but is able to ensure the operation of computer equipment without any problems. The built-in two-stage stabilization system operates at input voltages from 145 to 290 V, preventing interruptions and failure of electronic components. It can be started in the absence of input voltage (cold start) to create backup lighting or recharge gadgets. The battery charge level and operating mode are displayed using indicators. The manufacturer has used a fuse, so in emergency cases it will be impossible to continue operation without replacing it.

The inexpensive Eaton 5E 700 USB DIN Gen2 uninterruptible power supply provides optimal output power parameters (pure sine wave), which allows you to connect not only a PC, but also equipment that is sensitive to interference and distortion (audio equipment, medical devices, testers, LED lighting, heating boilers). The two-stage AVR copes with input voltages from 140 to 300 V. A USB port and a proprietary utility will provide timely control and adjustment of parameters.

High build quality increases operating comfort, since the UPS does not produce any extraneous sounds, and the overall noise level does not exceed 25 dB. Its weight is only 4.4 kg, so moving around an apartment or house to the right place will not be a problem even for a child. The 9 Ah battery guarantees decent autonomy (about 14 minutes) for one PC to complete all processes correctly. The manufacturer has provided only 2 output sockets, so connecting anything other than the system unit and monitor will be problematic.

The Powercom Spider SPD-750U LCD UPS offers universal installation (desktop, floor, wall) in vertical and horizontal positions. All controls, indicators and sockets are displayed on the front panel for easy connection and control. The backlit display shows basic information: voltage, battery status, operating mode. The battery has a separate compartment with a cover, so it can be easily replaced without having to disassemble the case.

In total, the user has 8 Euro sockets at his disposal, which provide stabilization of the output voltage within 220 - 240 V, depending on the settings. 4 sockets are connected to a capacious 9 Ah battery and allow the PC and peripherals to work autonomously, including in cold start mode. If necessary, you can recharge your laptop, smartphones, and flashlights. When powered from the main network, gadgets are charged via 2 USB 2.0 connectors with a maximum current of 2.4 A. Switching to the battery is carried out in 4 ms, eliminating interruptions in the operation of sensitive equipment.

The proprietary utility allows you to make changes to settings, control operating parameters, and even create a schedule after connecting to a PC via the USB-B interface. The UPS provides comprehensive filtering against electromagnetic interference and pulse surges. Additionally, RJ-45 ports have been implemented to prevent the failure of network cards and routers in the event of a lightning strike on the provider’s equipment.

The line-interactive uninterruptible power supply Powercom RPT-1025AP Schuko has an effective output power of 615 W. That is, it is designed to serve one or two jobs. Inside it are two batteries with a capacity of 7 Ah. The manufacturer claims that this is enough to ensure autonomous operation of a standard home or office PC (consisting of a system unit and a mid-diagonal monitor) for 7 to 10 minutes in the event of a power outage. In addition to working as a backup power source, the device functions as a voltage stabilizer. It automatically detects power surges and sags in the network and corrects them on the fly, providing connected equipment with high-quality current.

All connectors are located on the back of the UPS. There are 4 sockets into which you can connect electricity consumers (each of them is connected to a reserve and can be used for a “cold start”). Next to them there is a pair of RJ45 connectors (the uninterruptible power supply can protect a telephone or modem line from impulse noise) and a USB port. Through this port, from a computer on which the appropriate software is installed, you can control the operation of the uninterruptible power supply (for example, set a schedule for turning the device on and off) or monitor the main operating parameters (input and output voltage, load, battery charge, etc.).

Users note that the Powercom RPT-1025AP Schuko operates quietly even under full load. But at the same time, reviews of Powercom UPSs, including this model, contain widespread complaints about strong odors of plastic and varnish. Get ready for the fact that the new UPS will emit an unpleasant “Chinese” aroma for some time (from a couple of days to a couple of weeks) (although Powercom is, in fact, a Taiwanese company).

The APC Back-UPS 750VA BX750MI-GR UPS provides reliable protection of equipment from power surges, as well as short-term autonomous operation (about 7 minutes at 50% load) when the main power supply is turned off. The rated output power of 410 W is sufficient to connect two typical PCs or other equipment with appropriate consumption characteristics. For this purpose, 4 redundant F-type (Euro) sockets are provided. RJ-45 connectors are also implemented to filter interference and distortion over the Internet cable, eliminating damage to network equipment at home or in the office. The UPS contains all standard protection measures and an additional barrier against surges. The automatic fuse quickly responds to critical deviations in the power supply and does not require replacement to restore functionality.

APC Back-UPS 750VA BX750MI-GR operates effectively with an input voltage of 140 - 300 V. The system automatically responds to deviations, choosing the optimal scenario. The switching time to the battery of 6 ms ensures stable power supply for most equipment, including computers. The USB port allows you to synchronize the UPS with a PC, monitor and change system parameters using a special application. Considering the features, the retail price seems a little high.
