EVGA – you might have heard of it – it manufactures NVIDIA video cards, Intel motherboards and has a small selection of power supplies. The midrange and extreme PSUs has had a healthy offering from the SuperNOVA line up, but something in between has been missing. Today that changes with EVGA’s announcement of the SuperNOVA 1000W G2 Power Supply.
The best thing about EVGA’s PSU lineup is that all of its units carry a 10-year warranty – the standard being 5 years. The only catch is that you need to register your PSU on EVGA’s website within 30 days of purchase, which is a small price to pay when you can protect your $100-$500 investment for 5 more years. Other Key Features include:
80Plus Gold Rating Pending, with up to 90% efficiency under typical loads
Single +12V rail delivers up to 83.3A
Superior vertical double layer main transformer increases power output
Fully Modular design reduces cable clutter
Highest Quality Japanese Solid State Capacitors
Quiet 14CM Double Ball Bearing Fan
The biggest change I see is with the +12V rail; it is lacking additional rails this time around. The +12V rail is designed as one rail and then branches off to provide power to the subsequent other rails, thus you are drawing that power from one source, not multiple. The reason this is done is so that the PSU is less likely to catch fire.
The load balancing issues have become less of an issue with this and other changes made, but this PSU is intended to be a dual SLI/Crossfire solution at the very least. When I consider my past experience, I sure wouldn’t want to trust my system to one +12V rail without the redundant standard there is now; no matter how efficient the rail is or how robust the warranty is.
The next issue I see is that it is elongated; this is something that was common place back in 2007 for 1000W but isn’t common now. I am glad to see EVGA is filling in the gaps between its output offerings but it remains to be seen if we won’t see the same problems crop up that forced the change to using the multi-rail design used today.
