Performance (40% of the final score) – as is usually the case for budget units, the 450BT had some interesting things going on that need scoring. Because it is an old group design, voltage regulation was beyond mediocre giving us a 9.59% average in the hot box. It will lose all possible points for that section, 2.5. But that’s really the worst part of it. Efficiency was a pass for Bronze at all times, so no deduction there. The S&C point is safe because the unit nailed all the power on spike tests. And finally, we had nothing but excellence in the ripple shots, so no deduction there. That gives us a 7.5 here.

Functionality (20% of the final score) – this being a bargain unit, we can’t expect too much here. But we can expect some. A full point comes off the top for not being modular. Half a point goes for the Berg connector. Half a point away for thin gauge wire. Half a point vanished for documentation. And… I think I’m done with this category with another 7.5.

Value (20% of the final score) – you’re looking at $44.99 at NewEgg for one of these. The same price gets you an Enermax NAXN of unknown quality, but unfortunately for EVGA it also gets you a Corsair CX-M. With semi-modularity, DC to DC conversion for the minor rails, and overtemp protection. Yes, there are even cheaper units, but none of them are units I would personally buy. If you only have forty-five bucks, get the Corsair. If you have more, spend more. 4.

Build Quality (20% of the final score) – a full point comes off for fan quality. A full point comes off for soldering mishaps. A half point comes off for MOV shenanigans. Half a point for capacitors. A full point for no overtemp protection. And there we will stop. I really appreciated the upscale parts used on the primary side, but I find myself wishing that other parts of the unit matched them. 6.

The EVGA 450BT turned out to be somewhere in the middle of the recent bargain units from EVGA I’ve looked at recently. It’s not quite as good as the 450BV, but a little better than the 750N1. With that said, it is clearly an old group regulated unit built for systems of a bygone era, and I’m strongly advising you to get something more in tune with modern systems. This unit isn’t barking at the gutless wonder door, but it’s just not that good of a unit here near the end of 2018.


  • excellent ripple control
  • excellent turn on spike suppression
  • can handle a bit over rated temperature
  • great for old 5V based computers

The BAD:

  • lack of overtemp protection nearly allowed the 3.3V parts to fail
  • solder boogers on the mainboard


  • second tier capacitors
  • fan quality
  • can’t handle 12V heavy crossloads
  • over and under voltage protection is a bit loose
