I purchased this power supply unit (PSU), the EVGA SuperNOVA 650G1 650W ATX12V, in anticipation of upgrading my computer's original equipment manufacturer (OEM) graphics card with a much more powerful one. My reasons for selecting this particular PSU are:
- Gold Rated Efficiency.
- Reputation of EVGA.
- 10 year warranty.
- Very high quality of materials used in the design and manufacture.
- Fully modular design.
- Positive Customer reviews.
After installing the PSU into the computer (a Lenovo K450e) three days ago, I have continuously left the computer on and I have not had any issues with either the PSU or the computer. The PSU works and it is very quiet. In fact, so far, it has been silent; the only noise which I hear coming from the computer is that of the single OEM case fan and the spinning of the two internal hard drives. (Of course, this is due to the fact that the entire system is drawing far less than half of the capacity of the PSU and I won't test its capabilities until I upgrade the video card.)
Installing the PSU was a simple affair, if somewhat time consuming. In total, I required about an hour-and-a-half to shut down the computer, disconnect all exterior cables connected to the computer, remove the side panel from it, note all the connections from the OEM PSU to the various internal components of the computer, disconnect these power cables, remove the OEM PSU, install the new PSU, connect and route the new power cables (which were supplied with the new PSU), verify that everything was connected and ensure I did not inadvertently place a cable which would interfere with the operation of any component, reinstall the side panel, reconnect all the cables leading to the computer, and then powering it up. The length of time for installation was not due to any fault in the design of the PSU, but due to the tight tolerances brought about by the larger size of the new PSU versus the OEM one, and the limited space in the computer's case. I also deliberately took my time so as not to damage either the OEM or new PSUs, or any of the other internal components of the computer.
For those who care about aesthetics, the PSU is matte black with white lettering indicating which power connection port is for which component. The stickers on the PSU are elegant and do not distract from the overall look of the PSU. The supplied cables are covered in braided black fabric, with white letters on the connectors which clearly indicate for which component they are used. Once installed in my computer, I must say this PSU and cables look far better than the OEM PSU and its attached cables.
Overall, I am very pleased (so far) with it.
