The Gigabyte GP-UD1000GM PG5 survived our demanding exams and achieved first rate however not aggressive general efficiency. Its fundamental benefit is the 12+4 pin PCIe connector, however very quickly, all manufacturers will replace their PSUs with such connectors. Relating to ATX v3.0 compatibility, we came upon that the GP-UD1000GM PG5 has bother maintaining with this spec because it could not go all corresponding transient response exams. Which means we cannot embrace it in our greatest PSUs article. Different 1000W PSUs with larger efficiency, missing the 12+4 pin PCIe connector, for the second no less than, are the MSI MPG A1000G, the EVGA 1000 G6, and the Corsair RM1000x (2021).
Gigabyte shouldn’t be so well-liked within the PSU market due to the issues that the P750GM and P850GM models had. You possibly can observe this story right here. The newer era members of the P-GM line had solved all points, due to a PCB redesign. Nonetheless, there was no technique to distinguish the older fashions from the brand new, revised ones. Given the infamy of the P-GM line, Gigabyte determined to introduce the UD collection, which makes use of the brand new revision platforms discovered within the P-GM fashions however with totally different mannequin numbers. So the UD line consists of three members with 750W, 850W, and 1000W capacities, and just lately Gigabyte launched the UD1000GM PG5, the primary PSU obtainable in the marketplace boasting compatibility with the latest ATX v3.0 spec.
For a PSU to be appropriate with the ATX v3.0 specs, if it has over 450W capability, it must have a 12+4 pin (12VHPWR) connector and be capable to meet the strict energy excursions that the brand new Intel spec units. You possibly can learn concerning the modifications that the ATX spec 3.0 brings in our article.
The UD1000GM PG5 is the up to date model of the UD1000GM, with the latter being the successor of the P1000GM. The OEM stays the identical, MEIC, which primarily focuses on energy adapters however, because it appears, needs a chunk of the desktop energy provide market. The unit makes use of a totally modular cable design and has compact dimensions, due to its 140mm depth. It’s outfitted with a rifle-bearing fan, which can cope properly with the 10-year guarantee when you do not push it far at excessive working temperatures. From certifications, the UD1000GM PG5 comes with 80 PLUs Gold and Cybenetics Platinum in effectivity, whereas in noise, it’s rated as Cybenetics Customary+, so do not count on it to be silent.

That is the primary PSU to get a 12+4 pin PCIe connector. On the time of this evaluation, the one graphics card requiring this connector is the Nvidia RTX 3090Ti. The upcoming GPUs would require the brand new PCIe connector, rendering them incompatible with the present era PSUs. Using adapters could be an intermediate resolution, however we advise towards using adapters for such high-power outputs.
The 2 EPS connectors on the identical cable are unhealthy information, particularly with 18AWG gauges. These connectors can draw a lot of energy, so you possibly can have melted cables or connectors on the PSU’s facet when you plan to push them to their limits. There may be additionally no want for an FDD connector. They may change it with a 4-pin Molex one. Talking of 4-pin Molex connectors, the corresponding cable ought to have 150mm distance between them, which is the case for the SATA connectors!
Part Evaluation of Gigabyte UD1000GM PG5
We strongly encourage you to take a look at our PSUs 101 article, which gives invaluable details about PSUs and their operation, permitting you to raised perceive the elements we’re about to debate.

That is an upgraded model of the platform used within the PG1000M. We noticed a big distinction within the -12V rail, the place MEIC, the OEM of this platform, used a devoted daughter-board which is overkill, on condition that -12V shouldn’t be used anymore. We surprise why PSU producers and types nonetheless have it. The ATX spec has this rail as optionally available for fairly a while now.
The platform makes use of a contemporary design with a half-bridge topology on the first facet and an LLC resonant converter. In distinction, on the secondary facet, we discover a synchronous design the place FETs regulate the 12V rail, and a pair of DC-DC converters deal with the minor rails.
The transient/EMI filter consists of all obligatory components and a discharge IC, offering a slight effectivity enhance. The transient filter consists of an MOV, and there’s additionally an NTC thermistor, however a bypass relay doesn’t assist the latter. The 750W and 850W models of the identical line have such relays, however the 1000W lacks one as a result of there isn’t a area on the PCB. They need to use a unique PCB or format within the 1000W mannequin as a result of the bypass relay is crucial for inrush present safety.
The bridge rectifiers can deal with as much as 30A mixed, which is sufficient for this PSU.
The APFC converter makes use of two NCE Energy FETs and an STMicroelectronics enhance diode with 10A present rankings. The majority cap is by Chemi-Con and is among the many largest now we have seen. There was no room for a pair of caps put in in parallel, so that they had to make use of a single massive one. The APFC controller is a Champion CM6500.
The primary FETs are put in in a half-bridge topology. An LLC resonant converter can also be used for elevated effectivity. Lastly, the resonant controller is a Champion CM6901X.
Six FETs regulate the 12V rail and two DC-DC converters generate the minor rails.
The filtering caps are of common high quality. On paper, the specs of nearly all of caps are good, however we aren’t so keen on Lelon caps.
The standby PWM controller is a PR8109T IC. The rectifier on the secondary facet is a SP10U45L SBR.
The modular has a number of polymer and electrolytic caps, forming a secondary ripple filtering layer.
The primary supervisor IC is a Weltrend WT7502R.
Soldering high quality is basically good.
The cooling fan is by Jamicon, and it measures 120mm throughout. It makes use of a rifle bearing for elevated reliability and decrease noise output.
