Specifications

The unit is 80 Plus Gold certified, fully modular, and Haswell ready. The maximum operating temperature at which it can deliver its full power continuously is 50°C, which is in line with the ATX specification, and it includes all standard protection features except for OTP (Over Temperature Protection), which should normally be available in a high-end PSU.

Instead of the higher quality fluid-dynamic-bearing fan that equips its more expensive Super Flower Leadex Gold 750 W sibling, the G2-750 only comes with a double-ball-bearing fan. The G2-750 W still comes with the option to switch to a semi-passive operation and the for a 750 W unit large dimensions. Its price is very good for the specifications, and the warranty is ten years long, which is incredible.

The single +12V rail can deliver the unit's full power when needed, so it will easily support two high-end VGAs. The minor rails are also strong enough, and the 5VSB rail is a little stronger than the average, and we noticed the strange discrepancy that the mid-capacity Super Flower platforms feature stronger minor and 5VSB rails than the high-capacity units of the series. The SF Leadex Platinum 1200 W we reviewed a while ago had 100 W maximum combined power on its minor rails and only 2.5 A maximum current output on its 5VSB rail; it should definitely be the other way around!

Cables & Connectors, Power Distribution

Two EPS and four PCIe connectors equip this unit. We would, if they were to ask us, propose six PCIe connectors since 750 W could easily feed three mid-level VGAs and some users may go that route. However, those of you going for two high-end VGAs won't need more PCIe connectors as the unit isn't strong enough for more. With the main 24-pin ATX cable 600 mm long and both EPS cables close to 700 mm long, overall cable length is adequate in even very large cases, and the distance between connectors is good. All connectors also use standard AWG18 gauges.

We have nothing to comment on when it comes to the PSU's power distribution because it features a single +12V rail.
