Rosewill Tachyon Series 1000W Power Supply Review

Manufacturer: Rosewill

Final Thoughts and Conclusions

The new Rosewill Tachyon-1000 proved to be a good performer and offers solid features at a competitive price in the 1000W category. Voltage regulation, AC ripple suppression, and build quality were all very good. Our test unit struggled a little in meeting the 80Plus Platinum efficiency criteria but as we explained earlier this is most likely due to the difference between our real-world, elevated operating temperatures and the 80Plus organizations “room temperature” standard. The Tachyon-1000 features both fixed and modular cables which will appeal to some users and disappoint those looking for 100% modular.

The Tachyon-1000 power supply is currently selling for $189.99 USD (Newegg.com, February 2013).

I was going to say "What a great deal!" but then I looked up the price on Newegg. $240 bucks today. You've reviewed it too well.

If Seasonic's 1000W is cheaper with the rebate, has a better warranty, and a better reputation, then why would somebody go with the Rosewill? It seems like a strange pricing strategy by Newegg.

Maybe because the Rosewill performs better?

Maybe because if you actually understood what wrote in the reviews, you'd have seen that the Rosewill's ripple suppression is better?

Or maybe because you judged things by their brand like an idiot?
