![]() The cherry-on-top isn’t noisy, which is usually the case in PSUs from not so known OEMs. That said, the 750 GA is a bargain at 80 dollars, given its build quality, the fully modular cable design, and the ten-year warranty. I should not forget the APFC converter, which needs tuning for higher PF readings. With properly set protection features and a longer hold-up time, and why not, lower ripple at 3.3V, this unit would achieve a competitive overall performance score. Andyson, the OEM behind this unit, can make good products (e.g., the Aerocool Project 7 units), but its engineers need guidance. I didn’t expect such high build quality on the EVGA SuperNOVA 750 GA, so this was a nice surprise. On the other hand, it also doesn’t into account the lousy protection feature settings at 12V. That said, the last position in this graph is not indicative of this unit’s worth because this chart doesn’t consider the build quality. Ripple suppression at 3.3V also plays a role. The overall performance takes a large hit because of the low hold-up time. The PSU supports Alternative Low Power Modes, which the ATX 3.0 spec requires. Average NoiseĪverage noise is not high, but it would be nice if it were below 30 dBA. The APFC converter needs tuning for high power factor readings. As you can see, the explosive Gigabyte UD750GM tops the chart. Lastly, it achieves over 60% with a 2% load, but it is far away from the recommended 70% threshold. The unit achieves high efficiency levels with 115V input but loses ground with 230V input in the 20-100% load range. Inrush current is low with 115V, but this is not the case for 230V input, where I measured close to 89A. Normally, every PSU compatible with the ATX spec should have over 17ms hold-up time, but bulk caps are expensive. ![]() The hold-up time measurements show that this unit belongs to the mid category and not the high-end one, where lower than 17ms is not acceptable. It could be better on the other rails, though. Transient response at +12V is not below 1%, but you cannot call it mediocre. The 3.3V rail’s ripple could be lower to allow for higher overall performance. Ripple suppression is not among the top in this category, but it is pretty good on most rails. Load regulation is tight on all rails, but 5VSB where it doesn’t matter much. It won’t be as quiet, though, as an FDB fan, but in general, DBB fans are of higher quality. EVGA uses high-quality caps, and the cooling fan uses double ball-bearings, so it won’t have a problem at high temperatures. The heatsinks are of medium size, and the build quality is high. This OEM is capable of creating good products under the proper guidance. The OEM of this unit is Andyson, which I don’t often meet in my reviews. Parts Description General DataĤx Y caps, 2x X caps, 2x CM chokes, 1x MOV The 5VSB rail can also deliver more than double its official current rating. Moreover, OCP at 3.3V is set too high for no reason. It won’t survive, most likely, and this is a shame because OCP and OPP are supposed not to allow users to break, easily at least, their PSUs. This can be a problem if users push the PSU hard under high temperatures. OCP triggering points are set high on the 12V rail, and the over power protection is set crazy high.
