The EVGA SuperNOVA 750 GA would not outperform nearly all of competing choices within the 750W class, together with these among the many greatest PSUs . Nonetheless, at $80, it’s a good discount, given its excessive construct high quality and first rate general efficiency. Furthermore, the ten-year guarantee exhibits EVGA’s religion in its reliability.
There are a number of SuperNOVA energy provide lineups from EVGA. The GA one vary consists of 4 members with capacities starting from 550W to 850W. We noticed this one had optimistic critiques on Amazon and different resellers, so we selected to get and check one.
The 750W member of the SuperNOVA GA line can be our check topic. This unit has Gold effectivity within the 80 Plus customary and Silver within the Cybenetics scale. It additionally has a Cybenetics Commonplace++ noise score, that means that you simply will not want earplugs to make use of it. Apart from the totally modular cable design and compact dimensions, the double ball-bearing fan is one other attention-grabbing characteristic. DBB followers, usually, are most popular to FDB ones beneath harsh situations as a result of they’re extra tolerant to elevated working temperatures.

The OEM behind the SuperNOVA 750 GA is Andyson, a producer we do not usually see. This can be a disgrace as a result of we’ve seen some terrific platforms from this OEM previously, together with the Aerocool Mission 7 PSUs.

There are two EPS connectors on devoted cables and 6 PCIe on 4 cables. The variety of peripheral cables is satisfactory, however the distance between the peripheral connectors is brief, at simply 100 mm. Lastly, the in-cable caps within the ATX, EPS, and PCIe cables may trigger hassle throughout cable administration.

The principle FETs are 4 MagnaChip MDF18N50 , put in in a full-bridge topology. These FETs should not nearly as good by way of high quality because the FETs used within the APFC converters, however because of the full-bridge topology, the stress utilized to them is decrease. An LLC resonant can be used to offer a notable effectivity increase. The resonant controller is a Champion CM6901T6X .
