Comparison of Chieftec vs Thermaltake 1000W (850W) power supply
Comparison of Chieftec vs Thermaltake 1000W (850W) power supply
Can’t choose between three PSUs for RTX 4070ti and i7-12700k:
1) Thermaltake Toughpower Grand RGB 1050W Platinum;
2) Chieftec CHIEFTRONIC PowerPlay 1050W Platinum;
3) Thermaltake Toughpower GF3 850W Gold (no 1000W available locally).
They’re tier A according to psucultists’ list and cost similarly in my country.
Are the first two pretty much alike or is Chieftec using a newer CWT version? The third is an ATX3 but only 850W, which might not be enough for future upgrades. The first two aren’t ATX3 either, so they’re not ideal.
Which one should I pick?
I would choose the ATX 3.0 PSU. It provides enough capacity to support a 350W GPU. Unless you intend to upgrade to something like a 4090 with comparable power needs in the future, it won’t be a big concern.
4070Ti consumes just 285W, leaving room for overclocking if desired.
The third choice outperforms the other two options
Thermaltake Toughpower GF3 runs at ATX 3.0 and includes a 12VHPWR connector for new NVIDIA graphics cards
I would skip the Chieftec Chieftronic power supply here
Summary from one of its reviews:
The EPS and PCIe sockets match but aren't electrically compatible
Response time isn't strong, particularly at 3.3 V
High inrush current at 230 V
EMI suppression might need improvement
Not fully aligned with the latest ATX standard (v2.52)
