EVGA 100-N1-0650-L1 Power Supply Review

You are currently viewing EVGA 100-N1-0650-L1 Power Supply Review

EVGA is a business that was established in 1999 and is well-known in the field of DIY computers for its high-performance motherboards, video cards, and other parts. Power supplies have recently been added to EVGA’s product lineup, which of course piques our curiosity today. The N1 series is one of the power supply lines that EVGA currently offers.

We bought this power supply ourselves at a nearby retailer while it was on sale in order to conduct this assessment. EVGA 100-N1-0650-L1 Power Supply, the company’s largest power supply in the N1 series, is under evaluation. Although it also has a 750W and a 550W capacity, the one we are reviewing today is the top rated. On EVGA’s website, the MSRP for this power supply is listed as $69.99. It’s created in collaboration with HEC.

One of the first businesses in the consumer SMPS industry to be established was HEC Group (Heirochi Electric Corporation), also known as Compucase Enterprise CO LTD. It was established in 1979. HEC had transitioned into case manufacture by 1989, and in 1997 it started making SMPS. The HEC brand, the CompuCase brand, and the Cougar brand are all retail arms of HEC, making it one of the industry’s largest SMPS manufacturers today.HEC has formerly provided power supply for Antec, Thermaltake, Xigmatek, and other manufacturers in addition to its own. HEC has traditionally been recognized for its entry- to mid-level products, but with the introduction of some of its more recent models under the Cougar brand, it has entered the market for high-end enthusiasts.

EVGA 100-N1-0650-L1 Power Supply Specs & Performance

The EVGA 100-N1-0650-L1 Power Supply is a low-end power supply with poor efficiency, a noisy fan, and low-quality internal components. It also has poor overall performance. However, it was able to supply at full load at 36 degrees Celsius, and while the hold-up period is higher than what the ATX specification calls for, its transient response at 12V is acceptable. Its construction is subpar, and because OCP is improperly set, you should be careful not to overload its +12V rail. This is clearly not material for our list of the top power supply options, and you should purchase a Corsair CX650 or CV650 in its instead. If you have additional funds, you should also consider the comparable capacity Cooler Master MWE Bronze.

There are three products in the EVGA N1 range, with outputs ranging from 550W to 750W. These PSUs don’t have any modular cables because they are intended for the mass market, and they can supply their full power at a low ambient temperature of 25 degrees Celsius, according to EVGA. High-end PSUs can often operate continuously at full power at 50 degrees Celsius. However, they do it by using more expensive, higher-quality components than EVGA and HEC did for the N1 models.

The 650 N1 is capable of supporting a powerful graphics card, such as the Nvidia RTX 3070, theoretically, but I would advise against it because it only has two PCIe ports connected on a single cable that uses tiny 20AWG gauges. If you spent a lot of money on a good GPU, you need pay a little extra to buy a reliable power supply. It is not a smart idea to purchase a PSU with the money left over after paying for all the other system components.

CONCLUSION ON EVGA 100-N1-0650-L1 Power Supply

This EVGA 100-N1-0650-L1 Power Supply is a low-end model that may be reasonably priced. However, given their poor performance and efficiency, you should think about spending a little extra money to acquire a Bronze unit rather than a White one. Thankfully, the age of group-regulated PSUs is over.

Because the high over current protection at 12V and the highly set over power protection might quickly destroy this power supply at elevated operating temperatures, it is unfortunate that the protective mechanisms don’t function adequately. At least there is the over-temperature protection that every power supply needs. High EMI emissions, which can harm any electronics equipment in the same network, were yet another letdown.

We are perplexed as to how this device is being offered in a number of places, including Europe, where EMI emissions are supposed to be under certain limitations or the product won’t even be approved for import. However, the majority of manufacturers may receive EMI assessments from third-tier labs or simply test Golden samples to get around this problem. In addition, we purchased the sample for our evaluation because EVGA did not supply it; so, it is the same thing a typical buyer would discover in a store.

EVGA 100-N1-0650-L1 Power Supply is a great illustration of what you get when you skimp on the power supply. You might have a potent CPU and a very high-end graphics card. Still, if the power supply doesn’t offer steady and clean rails, these two will be dependent on it and obviously be impacted. It is strongly advised to utilize a high-quality PSU rather than a cheap one, even for lower-end systems.

Right now, there aren’t many possibilities if you’re seeking for an inexpensive 650W power supply because prices are so high. In some cases, the Corsair VS650 and CV650 cost the same as the EVGA 650 N1, while the Corsair CX650 is an even better choice. Look at the Cooler Master MWE Bronze 650 or the Corsair CX650F if you want to choose a high-end Bronze unit.
