Performance, Noise, Efficiency and Power Factor

Performance Rating

Gigabyte UD1000GM PG5 — (Image credit: Tom's Hardware)

The overall performance is not competitive. With a longer hold-up time, better ripple suppression at 12V and 5V, and tighter load regulation and transient response on the minor rails, the UD1000GM PG5 would be closer to the competition.

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 high.

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 average efficiency is high.

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.

So this is a 4 star product with 1, 2, 3, 4... 12 cons?

The cons are somewhat consistent with the review on TPU, but over there it was not a recommended product.

Maybe there's something more my ignorant self is not seeing here.

The Gigabyte UD1000GM PG5 is the first PSU available with a 12+4 pin PCIe connector, so practically, it doesn't have any competitors yet.

No thanks. I'd rather wait for Seasonic do one than get another one that could end up exploding

I understand the reference, but in this case, a unit with these many downsides doesn't justify a recommendation, unless there's something else besides being the only one available (for now).

Some of the positives are not that great either.
+Full power at 47 degrees Celsius
+Most protection features are properly set

Once beaten, twice shy. After the shady practice and persistent denial of critical flaws with their product by Gigabyte, even if this is a 5 stars PSU, I will not bother to consider it. There are much better options out there. I rather pay more than to deal with shady companies. In my opinion, it is not the product that we need to be mindful because every company will at some point produce bad product. It is how they take steps to resolve the issue and maintain that goodwill. Gigabyte basically burned that goodwill in the PSU fiasco. So no more Gigabyte products for me since the company can’t be bothered.
