The fresh Tachyon 1000 W includes all the necessary features for a successful presence on the market. For starters, it is based on Super Flower's top platform, something that grants it extra-high efficiency, tight voltage-regulation, excellent ripple-suppression, and a very good response to dynamic loads, which will be its daily routine in real-life scenarios. It, on top of that, uses nothing but Japan-made caps, which tend to last much longer than Chinese caps. They also age much slower, and that allows them to maintain the same level of performance for much longer. The PSU also operates in fanless mode at low loads – outputting almost no noise. Finally, the five-year warranty that Rosewill provides will ensure that the future buyer doesn't have to worry about the PSU for a fairly long time.

Its downsides, as far as I was able to spot them, are its small hold-up time, which is much lower than the minimum allowed by ATX spec, the absence of an MOV from the transient filtering stage, which means that you should use this PSU along with a surge protector in order to be fully protected, and the fan profile that will need some tuning. Actually, the fan circuit acts as an on/off circuit in my sample since the fan suddenly kicked into full speed from low RPM once I increased the temperatures inside my hotbox. Its speed increase should be linear and not so sharp.

To sum up, the Tachyon 1000 W is a high-performance PSU that manages to register a fairly good price/performance ratio thanks to its decent pricing scheme. This unit should be on the top of your list if you need such power and want the highest efficiency money can buy in this category along with top performance.
