The 80 PLUS® performance specification requires power supplies to be 80% or greater energy efficient at 10%, 20%, 50% and 100% of rated loads with a true power factor of 0.9 or greater. This makes an 80 PLUS certified power supply substantially more efficient than typical power supplies that offer below 80% efficiency.
With an EVGA power supply, efficiency ratings provide important characteristics about what you power supply is doing for you and your components.

When building on a budget or creating low-cost bulk projects, standard 80 PLUS rated power supplies provide cost savings per unit to provide a valuable solution that supports 80% efficiency. This may be the lowest rating supported; there are still products out there that only offer below 80% efficiency.
Heat affects all components in a system no matter how efficient they can be. The 80 PLUS ratings your power supply supports tells a story of what you get for the money you invested. The higher the rating means your power supply emits less heat exchange. Heat is the biggest enemy when talking efficiency, run a cooler system environment with top rated EVGA 80 PLUS Certified Power Supplies.
With or without software, have your power supply do its job for you automatically is a nice feature to have. EVGA Power supplies provide intelligent fan speed control to increase RPM only when needed. Reducing heat when needed keeps efficiency at its max and provides a controlled cooling environment for your system components.
The EVGA ECO Thermal System available on Platinum rated power supplies provides silent operation at low to mid range loads and longer life span of the fan. Reduce ambient noise and energy costs for your total operation when not needed. This optional feature allows the fan to completely stop providing NO NOISE during low to mid range load applications. This is an optional feature that can be toggled directly on the power supply to provide a convenient adjustment without any need for software.

EVGA provides a series of total safety protections to keep all components safe during normal to extreme power levels. Trust EVGA to provide a set standard in safety to cover multiple scenarios that can go from bad to worse if you don't have the right protection. These protections not only protect the power supply, but protect all components attached. Gain peace of mind knowing your system is protected from every angle with top-quality, power supplies by EVGA.
When looking for a new power supply, the total wattage provided is a big factor based on the components in the system. Keep in mind not everyone supports a continuous power design and it could affect your components performance if it cannot live up to its wattage. When you purchase a 1000W EVGA power supply, you are getting 1000Watts! Peak-rated power supplies may advertise they support 1000W, but this can only be for a few seconds to a few minutes and the unit cannot maintain the wattage it advertises. With an EVGA power supply, know what you purchase without any surprises and buy only continuous rated power supplies!
Every component needs power. To make sure you get the right power with the right connections and lengths depend on the power supply. If running 4-way SLI is your goal, you are going to need a lot of connections to support that configuration. Here is an overview of what EVGA power supply models have to offer when it comes to cables!
Reduce clutter in the case, improve ambient temperatures with better airflow overall and provide a clean look to any system. Fully Modular PSU designs allow the user to disconnect the cable from the power supply side if they are not needed for the specific configuration. This can help free up space inside the case and improve cable management as well as airflow throughout the system. EVGA offers fully modular designs on all 80 PLUS Gold or higher models and include a cable storage bag in case you plan to upgrade or add more components for storage.
The middle grounds when it comes to modularity, a semi-modular power supply provides select connections, when not needed, like extra peripheral cables (Molex, SATA) and PCI-E cables to be removed and stored. This will allow some options on the connections to provide better cooling and less clutter especially when working with a power supply that offers high-end SLI configuration when only running a single VGA card. With the hard wired cables you may need to do some work to get your EPS (CPU) cable up to motherboard or around a fan. Take a look at what you plan to use and get the right power supply for your case and motherboard you plan to use.
These types of designs are all hard wired to the power supply itself, no cables can be disconnected. When you settle for a high end version with multiple connections, be ready for some extra cables sitting at the bottom of your case. Hardlined or “Hard-wired” models can become a challenge depending on which side the cables are located in regards to fan placement causing the user to purchase an extension or work around if the cable is not long enough to reach. Low budget designs still use this type of layout to keep costs down for the customer, but in today's market you will see semi-modular and even fully modular designs becoming more affordable.
*As of this writing EVGA provides the highest warranty of 10 years on select power supply models.
With the introduction of Intel's 4th Gen Core Processors “Haswell”, the new C6/C7 sleep modes have made some changes that can be affected by your power supply. This affects the power supplies +12V rail minimum load rating which would require 0.05 Amps (4th Gen Intel) from the previous 0.5 Amps (3rd Gen Intel) processors. The other scenario combined with the lower +12V is keeping the load on the +3.3V/+5V rails as well. In order to prevent safety protections from kicking in like UVP/OVP (Under Voltage Protection/Over Voltage Protection), the power supply can be tested to become Intel 4th Generation CPU Ready which prevents it from shutting down due to protections as well as be able to maintain lower amp draw and not become unstable.
Ready your next system build by purchasing one of EVGA's Intel 4th Generation CPU Ready Power Supplies listed below:
A single +12V rail has all connections combined and monitored together. Total amps provided will be available from any connection. There is no advantage over a multi-rail design, just the design itself and how the power is distributed.
Multiple +12V rails designs provide separate monitoring of each rail. This provides a spread of the total amps available across more than one connection. There is no advantage over a multi-rail design, just the design itself and how the power is distributed.
LLC resonant converters are designed for DC-DC conversion for high end, high power applications with high efficiency. This layout provides easy ON/OFF control and helps with a series of safety protections to assure each unit is providing high efficiency, safely.
Fully modular designs allow every single cable to be removed from the power supply for ease of installation and removal. Save on space and reduce heat from unnecessary clutter by using fully modular or semi-modular power supply designs. EVGA offers fully modular designs on all 80 PLUS Gold or higher models.
