Supernova 750 G5 review

If you are looking for high-end power supply for your high-end custom mining rig then the EVGA Supernova 750W G5, 80 Plus Gold Certified Fully Modular Power Supply should be on your shortlist.


Gold Certification

Power supplies have different certification ratings and it all has to do with efficiency. All power supplies draw more power from the walls than they actually deliver to your computer. There is a loss when converting from the 110v or 220v that your wall supplies when down-converting to the 5v and 12v that your mining rig needs internally.

Basic power supplies are generally between 70% to 75% power efficiency, which means that they pull up to 30% more power supply from the wall than your mining rig actually needs. The lowest level of certification is the Bronze level. Bronze power supplies are generally in the 80 watts to 85 watts power efficiency range. They are about 10% more efficient than your standard no-name power supplies.

Gold power supplies are even more power-efficient. In countries that draw a standard 110v from the wall, a gold plus power supply is 90% efficient. In other parts of the world than use 220v its 92% efficient. This means that the EVGA Supernova 750 G5 80+ Gold will draw 20% less electricity from the wall compared with a standard no-name power supply.
