Rosewill Tachyon 650W PSU – Conclusion

The Tachyon series is currently the best which Rosewill offers, boasting a modular design, 80Plus Platinum certification, ratings at 50°C, excellent quality and performance. Super Flower’s expertise helped Rosewill a lot with that, delivering products which can really compete in the high-end segment of the market.

The overall performance of the Tachyon 650W power supply is very good. We could even dare saying that it was much better than we initially expected, considering that Rosewill is an infant when it comes to high performance products aiming towards hardcore enthusiasts. Nevertheless, the Tachyon 650W unit displayed excellent electrical performance, maintaining a tight voltage regulation and offering very good ripple suppression. Furthermore, the efficiency of the Tachyon 650W does meet the 80Plus Platinum certification levels just like Rosewill advertises, even if only barely. The running temperatures are very low, something which will especially please overclockers. Only the acoustics of the Tachyon 650W unit are average, with the power supply running silent only when lightly loaded.

The Rosewill Tachyon 650W

Design-wise, the appearance of the Tachyon 650W is simplistic but that is not necessarily a bad thing; on the contrary, we think that many modders will like its all-black design more than fancy engravings and stickers. The semi-modular design adds a lot of points, although the color-coded wires and standard cables are quite ordinary and perhaps even unsuitable for a product of this league.

Super Flower Design of Tachyon

Rosewill is a brand which usually is aiming towards maximum value for money. Value for money is a very relative term when it comes to high-end and extreme performance products, categories where the very definition of “value” is very fuzzy. We found the Tachyon 650W power supply retailing for $110.99 inc shipping after rebate at the time of this review, a very reasonable and competitive price for an 80Plus Platinum certified product. On the other hand, those not thrilled by the 80Plus Platinum certification and are willing to settle for 80Plus Gold/Silver products, they can find equivalent products for as much as 40% less. Rosewill’s own Capstone 650W unit, which is based on a similar platform and is an 80Plus Gold certified product, can currently be bought for $78.49 inc shipping after rebate, the value for money of which is definitely better. But for those wanting the best possible performance and efficiency and are unwilling to settle for anything less than an 80Plus Platinum power supply, the Tachyon remains one of the most competitive products in that league.

Legit Bottom Line: The Rosewill Tachyon 650W is a power supply balanced very well between high performance, good quality, decent design and value for money. If what you need is a reliable 80Plus Platinum power supply with good overall performance and do not want to break the bank, then the Tachyon should be among the first places of your shortlist.
