Chieftec has unveiled a new power supply line for the entry-level market with the Eco series. According to Chieftec, the Eco should provide “maximum flexibility in daily applications” and is outfitted with a subtly “green” appearance. We have examined the 500W model of the Eco power supply series in more detail to see if it can distinguish itself from other entry-level power supplies.

The Eco series, a new line of power supply units, was recently introduced by Chieftec.

These PSUs adhere to rigorous environmental ideals and are all in compliance with European regulations, as you may guess from the name.

The four PSUs of the Eco line, with power outputs ranging from 400W to 750W, are the GPE-400s, 500s, 600s, and 700s. The GPE-500s, a 500W AT X PSU with an efficiency rating of 85 Plus and ErP certification, is the type we have available for review. According to the ErP Lot 6 EU (1275/2008) standard, a computer’s standby or off power consumption cannot exceed half a watt. This decree and certification are followed by the Eco line.

CHIEFTEC GPE-500S Eco Power Supply Specs & Performance

The power supply is packaged in a white cardboard box with green accents and has the model number GPE-500S. The series name, “eco Series,” and the corporate emblem are shown at the top. The same thing is repeated on the pages. There are tables with performance information for the available Eco series vehicles on the back. The CHIEFTEC GPE-500S Eco Power Supply delivery remit is obvious. A short brochure with no really interesting information is included in addition to the power cord and mounting screws, but this is normal in this market.

Given the still low power class and the consequently smaller number of connection possibilities, the Chieftec Eco comes with fixed connection cables, but this is standard in this price level and poses no problems. The cables have different colors, and the ATX cable has a partially transparent sheath. The power supply also features two cables with two SATA connectors and one Molex connector, a 45cm long cable with a 4 PIN 12V CPU plug, and a 40cm long cable with a 6+2 PIN PCIe connector. This is in addition to the 40cm long cable with a 24 PIN ATX connector.

A few protective circuits ought to be included with the power source. For instance, the Eco models need to incorporate protection against overload, short circuit, and over/under voltage (OVP/EIA) (SCP). According to Chieftec, overheating (OTP) and overload (OCP) protection are not integrated. With the defined protection circuits, Chieftec at least meets the minimum need from our perspective, which is regrettably not always self-evident in this class.

The Chieftec Eco GPE-500S has quite respectable performance values, according to the feature list. Even though the power supply is not 80PLUS-certified, Chieftec claims a “85% Efficiency”. The power supply is configured based on the class, including output powers. On the secondary voltages, a total of 103 watts are available. Up to 37.5 amps, or 450 watts, can be loaded into the single-rail 12-volt side, which has a design capacity of 12 volts.

There were no issues during the commissioning and installation. Initially, we intended to test the power supply in a bigger case, such the Aerocool Xpredator II, but the cable lengths made this impossible. We therefore believe that the power supply is inappropriate for large or full towers. However, the cable lengths are more than plenty for Midi Tower and everything smaller. However, because some motherboards have two 12v 4PIN slots, you should keep in mind that only a 12v 4PIN CPU connector is available when purchasing the power supply. A single 6+2PIN connector is the only one that may be used to operate graphics cards, so keep that in mind.

For instance, the graphics card needed an adaptor to function because our GTX 760 has an 8 and 6 PIN connector. We used an adaptor for power measurement, but we do not advocate this for permanent use.

We increased the number of power supplies in the same power class on the table for our performance test.

When the Seasonic (Bronze) and the BeQuiet! (Silver) are higher certified, the GPE-500S performs fairly well.

Conclusion on CHIEFTEC GPE-500S Eco Power Supply

The GPE-500s are reasonably priced as well. Most system builders who want to have the least possible financial and environmental impact may comfortably afford it at just However, the absence of EPS and modular cabling places restrictions on this particular model. On the plus side, the GPE-500s’ overall build quality is good and the components used are great.

Although somewhat limited in terms of upgradeability, CHIEFTEC GPE-500S Eco Power Supply is nevertheless a solid power supply. However, it’s friendly to the environment, reduces your energy costs, and gladly integrates with the majority of users’ systems.

For smaller systems, CHIEFTEC GPE-500S Eco Power Supply is a decent entry-level power supply, especially when it comes to the length of the cables and the few connections. Even when it is working hard, it is quite quiet, and the cords and power supply housing are both well-organized. The GPE-500S is currently available for only 44,08 Euros. For desktop PCs, multimedia computers, and portable gaming systems, we advise the power supply.
