Chieftec A135 APS-600SB / APS-650SB

Two similar power supplies from the A135 series with a wide range of input voltages, differing only in power.

Specifications

These power supplies are suitable for residents of the private sector or remote areas of the city, where voltage sags often occur. And if there is no line-interactive UPS or stabilizer, then this is the only possible option. Since these power supplies can operate at voltages from 115 V and at the same time normally supply energy to all PC components.

In addition, they are bronze certified, have a relatively quiet 140mm fan, and are long enough for cables to be hidden in a small chassis. You just have to take into account that the length of the power supply here is 160 mm, but problems with this may only arise in very small cases. Power supply Chieftec A135 APS-600SB

How to choose a 600W power supply in terms of price/quality ratio?

When choosing a 600W power supply, the user should pay attention to four technical characteristics of the device:

1. Form factor . It affects which case the power supply will fit into. The most common devices now are those with the ATX form factor. They are distinguished by their compact dimensions and the presence of active cooling. Power supplies with form factors SFX, TFX and Flex-ATX are much less common.
2. Energy efficiency certificate . There are six such certificates in total: 80 PLUS (least effective), 80 PLUS BRONZE, 80 PLUS SILVER, 80 PLUS GOLD, 80 PLUS PLATINUM, 80 PLUS TITANIUM (most effective). Certified power supplies lose less energy and are more resistant to overheating. Basically, 600W power supplies are produced without efficiency certificates or with 80 PLUS and 80 PLUS BRONZE certificates. If the power supply does not have a certificate, then it is better to give preference to devices with at least initial certification.
3. Cooling system . It is desirable that the power supply has an active cooling system with at least one fan. Typically, power supplies with a power of 600 W are equipped with a fan with a blade diameter of 12 cm. Typically, such a device is sufficient to prevent overheating of the components of the power supply and its stable operation.
4. Connectors . Connectors are the cables with which the motherboard (20 or 24-pin), processor (4 or 8-pin), video card (6 or 8-pin), hard drives and storage devices (15-pin SATA) are connected to the power supply. fan and backlight (4-pin MOLEX). Connectors can be built-in or have a removable (modular) design.
5. Cable length . In order for the power supply to be conveniently installed in the case, it must have sufficiently long wires. The minimum cable length should vary between 60-65 cm. It is also good if all wires are equipped with braiding, as it will protect them from premature wear.

Zalman Wattbit XE ZM600-XE

In general, the famous company Zalman is not famous for cheap power supplies, but in the budget segment this power supply unit probably has no competitors.

Already from the picture you can see that the power supply is doing well with ventilation - a “grill” type grille, which has low resistance to air flow and does not create unnecessary noise, plus honeycomb-shaped perforations at the outlet provide excellent air removal.

Specifications

This power supply has a standard input voltage range, which means it will not be able to work normally in the private sector with a voltage drop below 200 V without a stabilizer.

To save energy, an active power correction circuit (APFC) is used. Some old power supplies with APFC could not work properly with a UPS, but in modern ones this problem has already been solved.

The power supply does not have an 80 PLUS certificate, but it claims a fairly high energy efficiency of 83+, while cheap power supplies have an efficiency of about 75%. PSUs with bronze and gold certificates have higher performance, the quality of the element base of which also has a positive effect on stabilizing the supply voltages of components. Voltage sags in such cheap power supplies begin after 50% of the load, while in older certified models after 60% and above.

Everything is fine with the connectors here, enough to power most motherboards with a 4 or 8-pin CPU connector, a video card with any connector configuration, up to 4 HDD/SSD drives and at least 3 additional fans (several can be connected to one Molex).

The specifications do not indicate the maximum fan speed, but if you follow the load recommendations, it runs very quietly.

Only the motherboard power cable has braiding, which can somewhat spoil the aesthetics of a case with a transparent window. In general, this does not affect anything else; the wires are long enough and can easily be laid behind the wall of the middle case, even with the power supply located at the bottom. You can find out the exact length of all cables on the manufacturer’s website.

The power supply does not have a modular design with detachable cables, which can be important when assembling a beautiful system with a large window without a casing covering the power supply.

The length of the power supply is minimal and is only 140 mm, which makes it easy to fit into any, even fairly compact, case. Plus the 3-year warranty is nice.

The power supply is assembled on a high-quality element base, there are standard protections (against overload, short circuit, etc.), as in all other power supplies from this collection, so we do not indicate this.

You will find more detailed characteristics of power supplies in the “Links” section.

In general, it’s a pretty good power supply, which we can recommend as a minimum option for assembling an entry-level or mid-range gaming PC. Power supply Zalman Wattbit XE ZM600-XE

Among the disadvantages, we can note the presence of braiding only on the motherboard power cable and the average length of this cable itself; in large cases with a bottom-mounted power supply, it will not be enough for hidden installation behind the wall.

Otherwise, the power supply is quite good and we can recommend it as a minimum option for powerful builds. Chieftec Force CPS-650S power supply

Thermaltake Smart BM2 550W power supply – TT Premium Edition

The new Thermaltake power supplies use a DC-conversion circuit with a single +12 V rail and active power factor correction. They provide protection against a variety of abnormal conditions.

The unit is equipped with combined cable systems. The 24-pin ATX, primary 8-pin EPS, and secondary 8-pin (4+4) EPS cables are rigidly attached on all four models. There are two 8-pin (6+2) PCIe power connectors available, while the 650W and 750W models have four each. A 750 W power supply can have cables with up to nine SATA power connectors, while the capabilities of other models are limited to six. All models offer four Molex and Berg connectors. The complete flat cables are enclosed in black insulation.

140mm fans are used to cool the components. The Smart BM2 series power supply comes with a five-year warranty.

be quiet! Pure Power 11 / 11 CM 600W

These power supplies are similar to the previous ones, but belong to the older, more efficient Pure Power 11 series.

Specifications

These power supplies feature a wide input voltage range as well as higher efficiency, certified gold. Thanks to this, they can be used in unstable networks, as well as for systems where the estimated power of the power supply is about 650 W.

There is also a small problem with the fans spinning up to maximum for a few seconds when the PC starts. But here the fans are slower and this is not so noticeable; in the future they work very quietly.

In this case, everything is the same with connectors and wires, but the length of the older modular model is slightly longer, plus the connectors on the outside add another couple of centimeters, so take into account the parameters of your case for the length of the power supply. The younger, non-modular model has another feature - a large coil of wires that needs to be laid somewhere.

In general, these power supplies can be used in gaming builds with one top-end video card and the ability to overclock the processor. Thanks to the high efficiency (92%) and digital stabilization, there will be enough of them. Also a nice bonus will be the extended warranty to 5 years. Power supply Be quiet Pure Power 11 BN294

Corsair CX650/CX650M

Corsair is famous for its quiet cooling systems and all thanks to proprietary fans. Power supplies in this case are no exception, plus they are distinguished by the high quality of the rest of the filling, including separate digital stabilization.

Specifications

It has all the necessary attributes of a good power supply - a wide input range, long cables with a sufficient number of connectors, a choice between a modular and non-modular model, a long warranty. And the presence of a bronze, rather than gold, certificate is compensated by the power of 650 W, which will be sufficient for the vast majority.

But the main advantage here is still the ultra-quiet fans. So, if you are building a silent system and are not very limited by budget, then the Corsair is an almost uncompromising option. It works quieter than any other power supply, although sometimes there are complaints about the fan being defective. It is also worth noting the very short length of the power supply, so that even a modular model will fit into any case, which contributes to the creation of compact systems.

Chieftec Proton BDF-600S/BDF-650C

Chieftec power supplies from the middle Proton series have proven themselves quite well and are, so to speak, the “golden mean” in terms of price/quality ratio.

Specifications

Both power supplies have a wide range of input voltages, but the older version is distinguished by greater power, modularity, and the length of the wires and the power supply itself.

Thus, the BDF-600S can be placed in a medium-sized assembly in a not very large case, and the BDF-650C in a more powerful and larger system. In any case, you will receive high quality and quiet operation of the power supply. Power supply Chieftec Proton BDF-650C

Thermaltake Toughpower GX1 600 / Russian Gold (Ural)

Some of the highest quality and reliable power supplies from Thermaltake for those who will have enough power with maximum stability, which is ensured by the use of premium components and a high level of digital stabilization.

Specifications

High energy efficiency also allows these power supplies to be used in top gaming builds with one video card, especially the 650 W Ural model.

Both power supplies have long cables with a large number of connectors, which allows you to create systems with disk arrays. But the Ural is modular and therefore longer.

The noise level of both models is low; in the Ural there are complaints about the quiet whirring of the fan, but not everyone experiences this. Both PSUs also come with an extended 5-year warranty. Thermaltake Toughpower GX1 SP-600AH2NCG power supply
