The Chieftronic PowerPlay 750 W uses the basic CWT GPR platform. In contrast, the Corsair RM750 uses a more advanced version with electrolytic caps of lower quality and a rifle-bearing fan instead of a DBB one. The PowerPlay has the same fan as the legendary Corsair AX1200i. Double ball-bearing fans are not that common in desktop power supplies nowadays because they produce more noise than fluid-dynamic or rifle-bearing fans. That said, they can tolerate much more abuse at high operating temperatures. Another major disadvantage of these fans is that they usually are more power hungry, so it is difficult to achieve high efficiency under very light loads. To give you an example, the RM750 uses a Hong Hua HA1425M12F-Z fan rated at 0.36 A, so its maximum power consumption with 12 V input is 4.32 W, while the Yate Loon of the GPU-750FC is rated at 0.7 A, which is 8.4 W power consumed at full speed! At high loads, an additional 4 W don't matter a lot, but even 1 W can make a difference at light loads.

Overall performance is satisfactory, although still not up to par with competing units, including the Corsair RM750 and RM750x models, Super Flower Leadex III of similar capacity, and XPG Core Reactor 750. This is a tough category, and the platform needs more tuning to achieve higher overall performance. Slightly tougher load regulation and a better transient response would help, along with a longer hold up time, which can easily be done by programming the LLC resonant controller accordingly. The significant pros of this model are the excellent ripple suppression, high efficiency levels, especially at light loads, caps of good quality on both the primary and secondary sides, and DBB fan, which is definitely better than any mid-range rifle-bearing or FDB fan.

I left the last two cons for last on purpose as they need to be elaborated on a bit more. The single EPS connector is a bummer in a 750 W power supply because it isn't enough for high-end mainboards and potent CPUs to achieve their peak performance. Today's powerful CPUs can draw lots of power, which means a single EPS connector isn't enough, so many mainboard require two of these, or an EPS connector alongside an ATX12V connector. Chieftronic should include two EPS connectors in a future version of this product if it is supposed to stay competitive. I also didn't like the fact that both PCIe and EPS sockets are identical. The PCIe sockets are painted red, but some users may still find it confusing, and wonder why their system won't start. The sockets should be different on the PSU side, or electrically compatible for both connector types. Finally, the shorter warranty compared to competing offerings will be a decisive factor for many buyers. I am not fond of incredibly long warranty periods as I believe many things can go wrong with a PSU, and too many returns over the long run spell trouble for brands and end-users alike. Providing ten years or more while our cars have five to seven-year warranties at most looks weird. Three to five years look more reasonable in my opinion, but there is the fact that the competition offers more, tactics I disagree with personally.
