EVGA SuperNOVA 1000 G7 Power Supply Review
The EVGA SuperNOVA 1000 G7 is a high performance power supply, challenging some of the highest capacity models on our best PSU list. FSP provided an excellent platform for his EVGA with small dimensions and high build quality. The strongest competitor is the Corsair RM1000x (2021), which offers the same performance level with noticeably lower noise output.
After a number of EVGA G-series revisions, we have arrived at the G7 on which FSP provides the platform. The G7 unit comes in four flavors ranging from 650W to 1,000W. Both have the same ultra-compact dimensions of 130mm depth as the SFX-L form factor. The dimensions of the 1000 G7 unit evaluated in this review are 150 (W) x 85 (H) x 130 mm (L). By comparison, the SilverStone SX1000 SFX-L measures 125 x 65 x 130 mm. This makes the 1000 G7 the smallest 1,000W ATX PSU available on the market. Some may wonder why vendors keep making smaller power supplies when the dimensions are defined in a very specific standard, unless that affects noise output and performance. ,I do not mind.
FSP had to install a 120mm fan as there was no space to install a larger fan. Thanks to the fluid dynamic bearings, the long 10 year warranty is no problem. EVGA, along with Corsair and Seasonic, was one of the first companies to offer such an extended warranty period.
The product box is small but contains a powerful 1,000W PSU. Internal protection is good, with foam spacers covering the edges of the PSU.
When you take the PSU out of the box, you’ll also see several LED indicators showing the load level of the PSU.

A wide range of long cables and connectors are available, including two EPS connectors and eight PCIe connectors. However, this PSU is not compatible with his ATX 3.0 or PCIe 5.0, so you won’t find a new 12+4 pin PCIe connector. Also, please increase the distance between the peripheral connectors.
Only ATX connectors have extra caps to improve ripple filtering.
Component analysis
I highly recommend taking a look at the PSU 101 article which provides valuable information on PSUs and their operation. You will be able to better understand the components that we are going to discuss.

FSP creates this little platform. As expected, it was overcrowded due to its large capacity, and it was very difficult to locate all the parts without destroying the PSU. PCBs like this always cause problems in the component analysis process.
The design is state of the art with a half bridge topology and an LLC resonant converter on the primary side. Also, a synchronous rectification scheme is employed in his secondary on the 12V rail and his DC-DC converter on the minor rail.
Transient/EMI filters have all the necessary components, so you can expect low EMI emissions. In addition, it is equipped with a MOV to handle voltage surges from the power grid, and we also found an NTC thermistor and relay combination to suppress high inrush currents.
A pair of bridge rectifiers are sandwiched between two heatsinks.
APFC converters use three FETs and one boost diode. The PFC controller is mounted on a vertical board made by Infineon. ICE2PCS02The same board also has an operational amplifier (op-amp).
two infineons IPP60R120P7 is the main FET configured in a half-bridge topology. Driver IC is Novosense NSi6602, and the LLC resonant converter is the normal side Champion CM6901T2X IC. There was no room on the main PCB, so the LLC resonant converter components were mounted on a daughter board.
The FETs regulating the 12V rail are mounted on the board next to the main transformer to minimize energy loss. Another vertical board hosts the DC-DC converter that handles the minor rails.
The filter cap is of high quality. All secondary electrolytic caps are Rubycon, polymer ones are Chemicon and NIC.
The standby PWM controller is from Power Integrations and NIKO-SEM P1006BD The FET is the rectifier on the secondary side of the 5VSB circuit.
Many Chemi-Con polymer caps are attached to modular PCBs for ripple filtering purposes.
The main supervisor IC is Weltrend WT7527RA.
The soldering quality is good.
The fans are of high quality and fluid dynamic bearings help extend the extended warranty period if you are not operating at consistently high operating temperatures (above 40 degrees Celsius).
