Conclusion

Five power supplies from Foxconn and Hiper Group have marched before you in this review. I was generally pleased with them. They are not exceptional products, but are not inferior to the available PSUs in their market sectors, either.

The only exception is the Hiper HPU-3S350. This allegedly 350W model cannot actually hold a load of above 250W and is shoddily manufactured. I am really astonished to see such a PSU coming from a company that positions itself as a manufacturer of expensive and high-quality PSUs. The HPU-3S350 is made with no higher quality than the numerous low-end models, including no-name ones, but it costs much more! So I just can’t honestly recommend it to you. You are free to choose a better model for the same money.

The other two models from Hiper belong to the more expensive Type R series and are not at all disappointing. These high-quality products fully comply with their specifications and are capable of yielding the specified full power. As for the drawbacks, the +5V voltage is set too high (this is not an accident as it was at about the same level in both PSUs) and there are some problems with the soldering quality (I do hope Hiper’s quality control is all right and does not let such problems pass too often). The choice between the senior and junior model should be based on their comparative functionality (the senior’s detachable cables, in particular), but not on the difference in their max output power which is going to be negligible in practice.

The power supplies from Foxconn aren’t very beautiful or original on the outside, but they feature independent voltage regulation to ensure a nearly ideal stability of the +5V and +12V voltages. Alas, the +3.3V voltage let down both models, especially the senior one, as it is unstable and spoils the cross-load diagram. Moreover, the output voltages ripple of the senior model is stronger than allowed at high loads.
