Hey, hey, hey, a high-quality power supply unit is on sale again for a relatively low price! Well, this one anyway: the Supernova 650 GT from EVGA, a 650W model with 80 Plus Gold certification and full modular cables, is now available on Amazon for just $49.99.

This is $80 below list price, and according to price tracking history provided by CamelCamelCamel (a super helpful resource when researching whether a discount is actually a bargain), prices typically fluctuate between about $80 and $120, with the average sale price exceeding $100.

The best PSUs for gaming are those that operate efficiently while providing enough wattage for your hardware (and future upgrades), and the 80 Plus certification grade plays an important role. The higher the rating, the less energy is wasted as heat.

80 Plus Gold certification means that the PSU operates at more than 90% efficiency at 50% load and 87% at full load. Although higher ranks (Platinum and Titanium) are also available, Gold is considered very superior (above Silver, Bronze, and the regular 80 Plus). For more information, see Tom's Hardware website.

In short, this is a high-quality PSU. It is also fully modular, which is especially useful when integrating PCs into small or crowded enclosures.

Is 650W Enough? According to Nvidia's specifications, a 650W PSU can run up to a GeForce RTX 3070. And if you look at AMD's lineup, you can install up to a Radeon RX 6700 XT.

With a high-quality PSU, you could even run an even more powerful graphics card with a 650W unit, although it would be a roll of the dice (we have seen RTX 3070s running on 500W PSUs, despite Nvidia's recommendation for 650W models (I have seen an RTX 3070 running on a 500W PSU even though Nvidia recommends a 650W model.) To get a rough idea of what you need, I recommend checking out an online PSU calculator like the one at OuterVision.

EVGA's Supernova 650 GT comes with a power-on self-tester and a 7-year warranty.
