But let’s proceed to the tests now.
The output voltage ripple is low even at full load. It is safely within the allowable limits.
The cross-load characteristics look very good – better than those of the above-discussed AQ series. The +12V voltage only sags more than 2% at greatly misbalanced loads, which are not possible in a real PC.
The PSU is cooled with a fan from InWin’s traditional supplier ARX, the FD1212-S3142E model. Alas, I have to note again that ARX fans are not always quiet even at low speeds.
The fan speed remains constant most of the time except for near-maximum loads but the PSU is not really quiet. The speed is not really low while the rather noisy bearing of the ARX fan is buzzing quietly, yet audibly.
The efficiency of this PSU breaks no records, but stays at a good level of 80% on average. The power factor is low, not making it even to 0.65.
The InWin IP-P350GJ2-0 is a good-quality, neat and inexpensive mainstream PSU for office PCs and undemanding home users. It complies with the ATX12V 2.0 standard, delivering the necessary parameters and declared output power. On the downside are the short length of the cables, the shortage of SATA plugs and the lack of a graphics card connector, and the use of inconsistent-quality fans.
