Thermaltake Toughpower PT 1000 ATX v3.1 PSU Review

Epilogue

The Thermaltake PT 1000 scores higher in its category than its 1200W sibling. Moreover, I noticed that in the 1000W model, the 3.3V rail performed much better than in the 1200W model, boosting the PSU’s overall performance a bit. Additionally, the 12V rail’s performance was better in the high-load transient response tests, because the peak load was 2000W, whereas in the flagship unit it was 400W higher. I should remind you that both models use the same type and number of FETs to regulate the 12V rail, which sounds weird. Apparently, the production cost of replacing the FETs in the 1000W model with different ones was higher than keeping the same ones.

The 3.3V rail’s transient performance remains mediocre, but at least the 1000W model didn’t fail in the tests I conducted with normal loads, unlike the 1200W unit. On the other hand, CWT used lower-capacity bulk caps on the 1000W platform, limiting hold-up time to below 17ms. Although it still meets the ATX v3.1 spec’s corresponding requirement, I still want to see a hold-up time exceeding 17ms. Additionally, ripple suppression is good, vampire power is dead low, and the platform’s efficiency across all load ranges is high enough. After all, this is a Platinum-certified unit in the strict Cybenetics scale. Finally, a great advantage of the Thermaltake PT 1000 is the fact that it is among the quietest PSUs in the 1000W category.

I left the protection features for last, which are correctly set in this unit. Although the differences between normal and high temperatures in the OCP triggering points of the minor rails are small, they remain highly conservative so that I won’t mark this as a con. I don’t often evaluate PSUs with properly tuned protection features, and this is one of the reasons I will recommend this unit.

All in all, the Thermaltake PT 1000 offers decent overall performance, and its protection features are correctly configured, which is a significant asset. If only it also had fan failure protection, which is nowhere to be found in most desktop PSUs.
