I fully agree with this comment, because now, two years later, there are still no major reviews of that unit which means Thermaltake knows it has platform issues and doesn't want it to harm sales of those units. PSU companies tend to send out units they know are excellent and shy away from sending out review units on their lower quality models.

Since it uses the exact same CWT platform as this unit, which scored a measly 8.6 on the JonnyGuru review, I'd say it's a dud and I'd avoid it and go with the XFX. These all use the same platform.
