В чём отличие БП?

Кто не рукоблудит на то, с какой страны привезли кондеры - разницы не заметит в работе

Впринципе все понятно.
The XPG Core Reactor II VE 750W is the affordable version of the Core Reactor II with similar capacity. It has fewer cables, and you probably won’t need that many anyway. It also has less expensive capacitors and some other minor part changes. The change of caps on the secondary side greatly affected the unit’s transient response performance, and this is something you should consider since the transient response is among the most important performance factors. The overall performance difference with the non-VE model is close to 5% at both voltage inputs I tried, 115V and 230V, while in the 850W unit, the corresponding difference is 4%. If indeed the VE models land at $20 lower prices than the non-VE models, they will be good bargains, given that a long warranty covers them, their performance is decent, and the cooling fan remains the same. Some of the competing models are the MSI MAG A750GL and the Thermaltake GF A3 750. The Core Reactor II VE performs better than TT’s unit at both voltage inputs and also outperforms the MSI unit at 230V, while at 115V, the latter has a slight lead. If XPG fixes the fan speed profile at high loads and lowers the unit’s overall noise output, it will be a good option for someone who wants a good PSU that won’t break the bank.
For performance freaks, the Core Reactor II will probably be worth the price difference, while for users on tight budgets, the VE line will be appealing.

У ve чуть проще некоторые компоненты, более дешёвые скажем так. Но вполне ещё на уровне.
