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. Dimensions (W x H x D): 150 x 85 x 150mm.Connectors: 2x EPS, 6x PCIe 6+2 pin (on 3x cables).Cooling: 135mm Double Ball Bearing Fan (RL4Z B1352512EH).Efficiency: Cybenetics Silver (85-87%), 80 PLUS Gold.If you're not particular about noise, it might even be worth hunting down the older model for its extra cables. The same goes for four-pin Molex connectors (four instead of six). SATA connectivity is scaled back as well: you get six connectors compared to the 650 G2's nine. So, it seems like the 650 G3 is a big step back in terms of cabling. We don't know the reasons behind EVGA's strange configuration, and we already noted that the previous-gen models had two EPS and four PCIe connectors. The SuperNOVA 650 G3 only sports one EPS connector and three PCIe ones, something that affects this PSU's usability. ![]()
