Gigabyte UD750GM Power Supply Review

Decent, efficient, and with a reasonable price tag.

Performance Rating

The overall performance is not competitive, staying behind most products in the same price range. Compared to the P750GM, the UD750GM scores a little better. 

Noise Rating

The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30 to 32 degrees Celsius (86 to 89.6 degrees Fahrenheit).

Under normal operating temperatures, the average noise output is relatively high. Given the not-so-high-quality filtering caps on the secondary side, we wouldn't suggest a more relaxed fan speed profile, though. 

Efficiency Rating

The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.

The platform achieves a high average efficiency score.

Power Factor Rating

The following graphs show the PSU's average power factor reading throughout its operating range with an ambient temperature close to 30 degrees Celsius and 115V/230V voltage input. 

The APFC converter need tuning for higher performance with 230V input.

    I will shortly be in the market for a new PSU and as part of a complete new generation ‘PC Build’ this coming December. Due to the extreme system importance of a PSU selection I never at first look at the pricing or its reasonable cost compared to other brands. But surely a 10-year unblemished warranty has usually driven me to EVGA and SEASONIC products. I am also now prone in looking at PSU’s with over 1200W as the new 4000 series GPU’s and other hardware coming on stream will become so much more demanding and power hungry. Enthusiasts I believe will also now be keeping their primary “Builds” much longer (5-years or more?) as hardware cost are spiraling out of control. So 10-year warranties and RMA services area big deal for me among many other expected PSU offerings like direct software control, digital readouts on the PSU itself, high quality cabling and product finishes.

    I'm curious if you did the GamersNexus tests. A lot of PC builders are going to wait for their tests before considering a Gigabyte PSU due to the exploding PSU issue they had
