Raijintek Ermis 450B 450W, SFX

The Ermis 450B is a decent, budget SFX PSU. Usually, the smaller, in dimensions, a PSU, the higher the price per Watt ratio, but Raijintek managed to keep the price tag on this product reasonably low. It doesn’t set any performance records, but it won’t let you down if you need a PSU for a non-demanding system. If you need more power, you can look at the Ermis 550B, and if you need a high-end SFX unit, you should spend more to get a Corsair SF750 which is included in my Best PSU Picks article.

Raijintek decided to enter the tough PSU market with a pair of highly affordable SFX units. Usually, "SFX" and "affordable" aren't combined, but Raijintek and the OEM, Casecom, have managed to develop a decent solution. The Ermis 550B is worthy of its price tag, offering a high performance per dollar ratio. Thus far, I haven't evaluated any other SFX PSUs of similar capacity below Gold-certified efficiency, so I had to use more expensive, higher-grade SFX units in my charts, which made for less than ideal comparisons to the small Ermis unit. If you don't want to spend much but still need an SFX PSU, you have an option now thanks to Raijintek. On the other hand, if money is not a problem, the best SFX PSUs money can buy today belong to the Corsair SF series.
