EVGA 450 B3 PSU Review

Performance, Value, Noise & Efficiency

Performance Rating

The following graph shows the 450 B3's total performance rating, comparing it to other units we have tested. To be more specific, the tested unit is shown as 100 percent, and every other unit's performance is shown relative to it.

The 450 B3 achieves a high overall performance score, leaving Corsair's CX450M in the dust. Then again, the CX450M didn't blow up during our review, neither is it a potential fire hazard.

Performance Per Dollar

The following chart may be the most interesting to many of you because it depicts the 450 B3's performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index. If the specific unit wasn't available in the United States, we searched for it in popular European Union shops, converting the listed price to USD (without VAT). Note that all of the numbers in the following graph are normalized by the rated power of each PSU.  

Priced at $50, EVGA's 450 B3 achieves a very high score in this metric.

Noise Rating

The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30°C and 32°C (86°F to 89.6°F).

Corsair's CX450M gets its revenge with ~3 dB(A) less overall noise output.

Efficiency Rating

The following graph shows the average efficiency of the PSU throughout its operating range, with an ambient temperature close to 30°C.

The efficiency difference between EVGA's 450 B3 and Corair's CX450M is small, though they both land at the bottom of this chart.

    Blowing up on the bench & the fuse not blowing seems to me to be rather more than an issue. I'd like Tom's to go buy another retail 450 Watt unit & see if it does the same. In addition, I see no mention of the other units in the range being tested which is odd as all models within the B3 line were purchased. Do we know if, say, the 550 Watt version suffers from the same safety issue.

    Further, EVGA's lack of response to this fault is not good for their PR. I'd even go so far as to suggest that such a dangerous failing should be grounds for banning this model from sale until EVGA can recall & fix the units.

    Hi there,

    Curious if EVGA came back to you, guys @ Toms Hardware on this on this fuse not working ...
    Seems to me the issue was serious enough to warrant an investigation !

    Did they really not come back with an explanation ????
