The Thermaltake Toughpower PF3 850W is a Platinum certified power supply, featuring ATX v3.0 and PCIe 5.0 compatibility. It is way more expensive than the Toughpower GF A3 850W which, but does it worth the extra money? Read the full review to find out, sorry no spoilers!
The Thermaltake Toughpower PF3 850W is included in my best ATX v3.0 & PCIe 5.0 PSU picks article.
I have already evaluated two members of the Toughpower PF3 family:
All PF3 units (and GF A3) are made by HKC, which looks to have made a very good offer to TT to change OEM for its new lines. Wherever this will be for good, it will be shown soon. The fact is that the PF3 line is way more expensive than the GF A3 one, offering higher efficiency. In this review, I will check whether it is worth investing 174 dollars for the PF3 850, or you could save lots of money and get the similar capacity GF A3 model instead, which at the time of the review costs $110.
The PF3 850 is Platinum certified by Cybenetics, and it has a Cybenetics Α- (25-30 dB[A]) noise rating, meaning that its fan doesn’t generally spin at high speeds. Regarding the cooling fan, TT speaks of a fluid dynamic bearing, which might be true, but the fan is not from a known OEM, which is a shame considering the PSU’s stiff price. I expected to find at least a Hong Hua fan in this price range, but HKC probably doesn’t have a good relationship with this fan manufacturer. Please note that the capacitors and the cooling fan are two of the most important things inside a PSU. If the fan dies, everything else will be highly stressed and can even fail, depending on the operating conditions. Only over-temperature protection can save the day from a fan that stopped operating, along with fan failure protection, which is not present in 99% of desktop PSUs.
