Cooler Master V700 reviewed - Testing

Review:
700W PLUS Gold Power Supply

Cooler Master V700 is a 700W power supply. It is 80 PLUS Gold certified, which means that it has to churn out 87%, 90% and 87% efficiency for respective workloads of 20%, 50% and 100%. This also means that it's efficient and won't waste energy. Unfortunately, we didn’t have access to professional PSU testing equipment, so we'll have to rely on 80plus.org's data. The following graph shows that efficiency is above or around 90% most of the time. You can find out more here.

Practical application tests prove that this is a quality PSU. Two Geforce GTX 780 graphics cards in SLI will helped us place a lot of strain on the V700, so that we could test fan loudness and stability of the entire rig.

One of the problems faced by quite a few high-end PSU users is that their powerful PSUs can cause the fuse to switch off as soon as the PSU is switched on. This shouldn’t happen, but it can happen if the PSU draws too much power, a high inrush current. As for the V700 we can confirm that we did not experience any such issues.

In standby mode the power consumption was just 0.2W. Our test rig featured an EVGA X79 FTW motherboard, Sandy Bridge-E Core i7 3820 (4.2GHz) and two Geforce GTX 780 cards in SLI. We used Prime95 to stress the CPU and Unigine Heaven to stress the graphics cards. Under full CPU and graphics card load, V700 ran like a charm. Maximum consumption was 656W.

The fan (Protechnic MGA13512XF-O2) was inaudible in idle mode but also stays quiet under full load. According to the spec sheet, the fan can run at 1800RPM, but it did not exceed 1000RPM during our tests.
