Pros, Cons And Final Verdict
It's been a while since we last reviewed a Thermaltake PSU, and although the DPSApp suite hasn't changed significantly, the hardware definitely received an upgrade compared to the old CWT platforms. Enhance is a solid OEM with high build quality and steady quality control. However, its designs aren't as extreme as what we're seeing from Super Flower, Seasonic or CWT. They don't offer the ground-breaking performance able to set new standards. The TPG-1200D-P does feature tight load regulation at +12V and high efficiency overall, along with fairly good ripple suppression. On the other hand, load regulation on the minor rails isn't tight, and ripple at 3.3V should be lower since this definitely qualifies as a high-end power supply. The hold-up time is also low, while the power good signal drops late.
We do like this model's digital interface, which facilitates monitoring and partial control through the DPSApp application. Speaking of DPSApp, though, it needs a number of fixes or even a complete redesign if Thermaltake wants to keep pace with competing utilities like Corsair's redesigned Link software. The interface remains the same since the last time we worked with DPSapp, and that's not a good thing. Sure, it may be easy to navigate, but you don't get any options for customization. You can't even rearrange the icons/functions. Moreover, once an alarm is activated, the program becomes totally unusable as it hammers your email account with notifications. Thermaltake's programming team should correct that behavior as soon as possible. They should also increase the over-temperature threshold, since 60 degrees C looks to be low for a PSU that promises continuous full power delivery at 50 degrees C ambient.
In general, the TPG-1200D-P is a decent performer. High-quality components and robust construction will ensure a long useful life, backed by a generous seven-year warranty. With some fixes, this platform could pull even with some of the most attractive power supplies in this category. For starters, Thermaltake should focus on extending this PSU's hold-up time and improve the DPSapp, which is one of the TPG-1200D-P's most interesting features. Of course, a significant price drop would help boost sales, too.
