ANTEC VP650P PLUS Power Supply Review

You are currently viewing ANTEC VP650P PLUS Power Supply Review

The Delta Electronics VPF650 is a low-cost power supply unit that offers good performance for the money. The EarthWatts Green series is used to market the VPF devices in the US.

Finding a PSU in this price range that only uses Japanese capacitors is quite challenging. The ANTEC VP650P Plus Power Supply, along with its American counterpart, the EA-650 PSU, provides good performance and earns a high performance-per-dollar rating because to its reasonable price.

At this year’s Computex, we first learned about the new VP units with 350 to 650W capacity and 80 PLUS Bronze efficiency. The current attempt from Antec is aimed at the typical customer who needs a dependable, cost-effective PSU for a mid-range system. Representatives of the company informed us that they had opted against using the VP name in the American market. Instead, the EarthWatts Green brand sells the VP series. The name on the boxes and labels is the only distinction between products marketed in Europe and the US, claims Antec. The VP supplies sell for a reasonable price in Europe (about $57 for the VP650); in the US, the EarthWatts Green series costs a little bit more, with the EA-650.

The ANTEC VP650P PLUS Power Supply new generation is built for quality, performance, and amazing value.

This entry-level option is certified to the 80 PLUS® 230V Standard and has a power range of 500W to 700W. It saves energy thanks to its excellent efficiency of up to 85%.

ANTEC VP650P PLUS Power Supply Specs & Performance

The VP line’s most potent model, with a maximum output of 650W, is what we’re testing today. This device just has the main ATX cable sleeved in order to reduce manufacture costs. Modular cabling is not used in this device. The remaining cables are left unprotected, which seems odd considering that even the most budget-friendly PSUs—at least the branded ones—have sleeving throughout. However, considering that Delta Electronics is the biggest and one of the top PSU manufacturers in the industry, this is not a cheap supply. Its implementations are not inexpensive. Currently, Delta only produces desktop PSUs for Antec. That’s probable because only Antec was able to maintain a working contract with the company while Delta lost interest in the market.

The upgrade to Bronze makes a big difference because the prior VP series carried a simple 80 PLUS certification. With its four PCIe ports, the VP650 can also accommodate up to two premium graphics cards. Additionally, it is compatible with the sleep states made available by Intel’s Haswell CPUs (S6 and S7). This means that while the +12V load is very modest (Intel’s test method only calls for 0.1A), it can give the full load on the minor rails (5V and 3.3V) without any issues.

The VP P PLUS series, which uses active PFC and provides efficiency at both high and low loads, delivers up to 85% efficiency, living up to the performance standards for which we are renowned.

The ANTEC VP650P PLUS Power Supply may operate at maximum power on two +12V rails. The minor rails are therefore controlled by DC-DC converters, and their maximum combined power is sufficient for the demands of a modern PC that mostly uses the +12V rail.

Antec provides this low-cost PSU with enough connectors to easily provide its full power, operating a system with up to two potent graphics cards, even though all cables—aside from the main ATX cable—are not shielded. The SATA connectors are also sufficient for this capacity. However, we did find it a little odd that the same cable had a single SATA, three four-pin Molex, and an FDD connector placed on it. Regarding cable length, it would be preferable if the ATX cable was 55 centimeters long and the EPS connector was at least 60 centimeters away from the power supply. However, the current connection length shouldn’t be a problem since this PSU will probably be fitted in a medium-sized case.

Finally, standard 18-gauge wire is used in all connectors.

The single EPS connector is not intermingled with the PCIe connectors and is powered by a separate rail. Definitely take this route. However, we object to the 12V1 rail having too many connectors while the 12V2 rail only has the one EPS to worry about. If it were up to us, all PCIe connectors would be powered by 12V1, and the remainder by 12V2. The load would be considerably more evenly distributed this way.

ANTEC VP650P PLUS Power Supply Conclusion

Since Delta is regarded as one of the best and most costly companies, its implementations typically come at a steep cost. Thankfully, Antec (currently the only business that collaborates with Delta in the production of desktop PSUs) is able to strike a favorable contract, resulting in the introduction of its budget-friendly VP line. Antec abandoned cable sleeving and all modular cables in order to reduce the price of the VP series. Inside the PSU, however, where premium Japanese capacitors are employed for greater dependability, no concessions were made.

Such high-quality capacitors, especially polymer ones, are quite rare to obtain in an affordable unit. In addition, the platform includes DC-DC converters for creating the minor rails, making it simple for it to pass Intel’s strict criteria for Haswell compatibility.

The ANTEC VP650P PLUS Power Supply had a solid performance, although we preferred to see greater efficiency scores across the board. However, the PSU performed admirably in areas that are crucial for the longevity of the components it will power, such as ripple suppression and turn-on transient performance—not just when compared to similarly priced but also against considerably more expensive alternatives.

Our most concerning findings in terms of the design’s drawbacks were the readings for the inrush current. Delta should investigate this issue and most likely employ a suitable NTC thermistor to reduce strong inrush currents that could harm switches, relays, and other parts. Additionally, there was no usage of a metal oxide varistor in the EMI/transient filtering stage. In the event of voltage spikes, this affordable component can protect not only the PSU but the entire system. This is why, in the event that you cannot afford an uninterruptible power supply, we always advise utilizing the ANTEC VP650P PLUS Power Supply (as well as any PSU that lacks a MOV or a TVS diode) in conjunction with a surge protector.

In conclusion, the Antec VP650P PLUS Power Supply, along with its American equivalent, the EA-650, provides reliable performance at an affordable price. There is still room for development, though. The OEM for the VPF series, Delta, can somewhat improve efficiency by incorporating a MOV and suitable inrush current protection into the platform, which results in a superior end product.
