EVGA SuperNOVA 550 G2 220-G2-0550-Y1 80+ GOLD 550W Fully Modular EVGA ECO Mode Includes FREE Power On Self Tester Power Supply
Pros: Top quality. Fully modular. I build desktop computers as a hobby. 550W is plenty of power for most desktops, unless you are a serious gamer. Latest build included H170 Intel motherboard, Skylake quad core processor with hyperthreading, GTX 750 graphics card, Raid 1 with one 240 gb ssd, and two 5 tb hdds. PSU packaging is designed to fully protect the product during shipment. Outer carton was crushed during shipment, but absolutely no damage to the product inside. Absolutely silent running. I can hear the extra silent case fans, but I can't hear the PSU at all. Maybe if I turned off the case fans entirely, I might be able to hear something. Extras included like a bag for the unused cables is a nice extra touch. I was impressed by both the quality and the features of this power supply unit the first time I bought one. I have now used this power supply in three computer builds. In the past I have used Rosewill, Antec, Thermaltake, and Dynex. I prefer this one over all the others. I will use this power supply again. It is solid, dependable, and has all the cables needed and the cables are long enough for even the largest of towers. I used this in a full sized ATX build, and a mid tower Haswell build. Fully modular means I don't have to clutter up the case with unwanted and unused cables. I completely recommend this power supply. So far all three are operating flawlessly.
Cons: None so far.
Overall Review: If you are a serious gamer powering multiple graphics cards and a lot of real estate on your monitors, 550W won't be enough power. But for my purposes it is just fine.

EVGA SuperNOVA 550 G2 Review & Specs
* First availability for purchase, it may not correspond to the actual market launch date.
EVGA has one of the most complete PSU portfolios today, with many products covering all market segments from low- to high-end. One of the most popular PSU lines EVGA offers is the G2 PSU series, which consists of units made by Super Flower that offer outstanding performance-per-dollar. Recently, EVGA expanded its 80 Plus Gold efficiency G2 line with two new models featuring 550 W and 650 W capacities, fulfilling the demands of users that seek lower-capacity and high-performance PSUs. Most manufacturers offer high-performing platforms only in high capacities, but this is starting to change. Super Flower is among the first to make high-end offerings available in the mid-capacity region, even including Titanium efficiency models. Since EVGA cooperates closely with Super Flower, we expect to see lower-capacity units in the Platinum (P2) and Titanium (T2) PSU lines very soon.
Today we're reviewing the EVGA SuperNOVA 550 G2 PSU, currently the smallest unit in the G2 line. Like other G2 PSUs, the 550 W model is based on Super Flower's Leadex platform, offering 80 Plus Gold efficiency along with a fully modular cabling design and a semi-passive operation. Because of the highly efficient platform, the relaxed fan profile, and a long-lasting passive mode, we expect this unit to offer very quiet operation, even under tough conditions. With its three PCIe connectors, the 550 G2 PSU can easily power a midrange system with a single high-end graphics card. Additionally, the PSU's price looks reasonable considering its features.
Coincidentally, one of the most direct competitors of this model is another EVGA offering, the SuperNOVA 550 GS, which is made by a Super Flower rival, Seasonic. The 550 GS currently costs the same as the 550 G2 on EVGA's online store, but comes with a shorter five-year warranty. Once we have all the test data in hand, we will compare these two units in order to find out which offers the higher overall performance and which is less noisy. Because of the larger fan diameter (140 millimeter) in the 550 G2 model, we believe that it will offer quieter operation compared with the 550 GS unit, which uses a 120 mm diameter fan.
As mentioned, the 550 G2 meets 80 Plus Gold standards and features a fully modular cabling design. It is also Haswell-ready, since it uses DC-DC converters for the generation of the minor rails and is equipped with all basic protection features except for the important Over-Temperature Protection (OTP). This platform can tolerate high operating temperatures, a fact clearly shown in the maximum operating temperature at which it can deliver full power continuously. However, since it features a semi-passive mode, it should also include OTP. In the cooling section, a 140 mm double ball-bearing fan removes the hot air from the unit, and due to its quality bearings and semi-passive operation we expect it to have a very long lifetime. Finally, the PSU's dimensions are typical for this capacity, and at seven years the warranty is very long, although it doesn't reach the 10-year period that covers the higher-capacity G2 members (starting at 750 W capacity).
|Total Max. Power (W)||550|
The single +12V rail can deliver the unit's full power, while the minor rails can deliver up to 110 W combined, a power level that will suffice for any mid-level system. Finally, the 5VSB rail has a maximum current output of 3 amperes, making it is strong enough for a 550 W PSU.
Cables And Connectors
|Description||Cable Count||Connector Count (Total)|
|ATX connector 20+4 pin (600mm)||1||1|
|4+4 pin EPS12V (700mm)||1||1|
|6+2 pin PCIe (700mm+150mm)||1||2|
|6+2 pin PCIe (700mm)||1||1|
|4 pin Molex (500mm+100mm+100mm)||1||3|
|FDD Adapter (+100mm)||1||1|
The 550 G2 has one less PCIe connector compared with the same capacity GS model, which costs about the same. In addition, it comes with only one EPS connector, while the 550 GS unit has three. We would like to see an additional EPS connector in this unit as users with high-end mainboards will need a second EPS or ATX12V connector and it isn't safe to use 4-pin Molex adaptors.
The number of SATA and peripheral connectors is pretty high for a unit in this category. And EVGA will provide an FDD adapter for those who will need one. Cable length is adequate, although the distance among 4-pin Molex connectors is too short at 10 centimeters (usually, the components that are powered by 4-pin connectors are located far from each other). On the other hand, the distance between SATA connectors is ideal since in most cases HDDs/SDDs are installed close to each other. Finally, the main ATX, EPS and PCIe connectors use thicker 16AWG gauges, whereas the rest of the connectors use the standard 18AWG wires.
Since this PSU features a single +12V rail, we do not have anything to say about its power distribution.
