EVGA SuperNOVA 750 P2 PSU Review

The PSU market wil attract to a lot of companies available and EVGA is one. The organization only offered one high-finish unit initially and released many PSUs to pay for all areas afterward-mainstream, mid, and-finish. The SuperNOVA G2 series is EVGA’s second-best series and until lately contained 3 units we already reviewed, the G2-1300 and G2-1000. EVGA apparently also searched for to determine a name within the popular market segment below 1 kW, which brought towards the discharge of the G2 850 W and G2 750 W. The units will also be by Super Flower, as both derive from SF’s high-finish Leadex platform.

We’ve the G2-750 with Gold-certified efficiency on the test bench today. It relies on a fully modular cabling design and provides the consumer the opportunity to switch from a semi-passive and normal operation in which the fan is continually engaged, although its speed is thermally controlled. Basically we aren’t huge fans of semi-passive PSUs since the condition puts a lot of force on such sensitive components as electrolytic caps without offering much when it comes to noise reduction, enough users with incredibly sensitive hearing will prefer it. The most powerful points from the G2-750 are most likely its excellent cost and also the huge warranty of 10 years! EVGA may be the first company using the guts to provide this type of lengthy warranty having a PSU product, so we congratulate them for this. They ought to be really positive about the woking platform to possess struck this type of decision, or SF backed them on it. However, Super Flower really only offers 5 years using their products, therefore we believe EVGA to most likely be by itself after 5 years.


Readily stored away 80 Plus Gold certified, fully modular, and Haswell ready. The utmost operating temperature where it may deliver its full power continuously is 50°C, that is using the ATX specs, also it includes all standard protection features aside from OTP (Over Temperature Protection), that ought to normally be accessible inside a high-finish PSU.

Rather from the greater quality fluid-dynamic-bearing fan that equips its more costly Super Flower Leadex Gold 750 W brother or sister, the G2-750 only has a double-ball-bearing fan. The G2-750 W still has the choice to change to a semi-passive operation and also the for any 750 W unit large dimensions. Its cost is excellent for that specifications, and also the warranty is 10 years lengthy, that is incredible.

The only 12V rail delivers the unit’s full power if needed, therefore it will easily support two high-finish VGAs. The minor rails will also be sufficiently strong, and also the 5VSB rail is a touch more powerful compared to average, so we observed the strange discrepancy the mid-capacity Super Flower platforms feature more powerful minor and 5VSB rails compared to high-capacity units from the series. The SF Leadex Platinum 1200 W we reviewed not long ago had 100 W maximum combined turn on its minor rails and just 2.5 An optimum current output on its 5VSB rail it ought to certainly be the other way round!

Power Specifications

EVGA SuperNOVA G2-750 Power Specs
Rail 3.3V 5V 12V 5VSB -12V
Max. Power 24A 24A 62.4A 3A 0.5A
120W 748.8W 15W 6W
Total Max. Power 750W

The minor rails are only able to provide 100W combined, though which should suffice for many modern systems. The only 12V rail is fairly strong it’ll easily support two high-finish graphics cards. We’d want to see a beefier 5VSB rail with a minimum of 3A max current output, though.

Cables And Connectors

Modular Cables
ATX connector (600mm) 20+4 pin
4+4 pin EPS12V (700mm) 2
6+2 pin PCIe (700mm) 4
SATA (550mm+100mm+100mm) 9
4 pin Molex (550mm+100mm+100mm+100mm) 4
FDD adapter (+100mm) 1

EVGA’s SuperNOVA 750 P2 has got the same cable/connector configuration because the 850 P2. You receive two EPS and 6 PCIe connectors, which can be found simultaneously. A set of the PCIe connectors has only six pins (instead of eight). So, in writing a minimum of, they are able to deliver as much as 75W each.

The amount of SATA connectors is elevated, as the four-pin Molex connectors should cover most storage and fan configurations. Cable length is acceptable generally, however, the space between SATA and peripheral connectors is simply too short, that could create problems. Within our opinion, there must be a minimum of 15cm together, since oftentimes they feed components spread farther apart. Finally, the 24-pin ATX, EPS and PCIe connectors use thicker 16-gauge wires, as the other cables employ 18-gauge wires.


EVGA’s cooperation with Super Flower delivered another really good product, the SuperNOVA G2 750 W PSU which excelled throughout my tests. Current regulation was very tight, which means incredibly stable voltages, and efficiency was high for a Gold-certified PSU. Ripple suppression seemed to be excellent, so you’ll easily attain the greatest possible overclock for the system while minimally stressing components responsive to ripple, like electrolytic capacitors. SF’s new Leadex platform which the G2-750 relies is completely fantastic, and also the only downside I possibly could find was it is not-so-efficient 5VSB circuit which requires a redesign to be able to match the PSU’s other circuits. But 5VSB efficiency cannot spoil the general excellent picture the G2-750 draws, which easily nets it a Suggested award from me. The cherries on the top would be the 100% Japanese capacitors used (the SF Leadex unit used a couple of CapXon caps) and it is great cost tag, which considerably enhances the unit’s cost/performance ratio. For last I left the large ten-year-lengthy warranty EVGA offers all of their high-finish PSUs, which clearly includes that one.
