Gigabyte UD1000GM PG5 1000 W

[crmaris]

The Gigabyte UD1000GM PG5 is the first available PSU with a 16-pin PCI-Express 5.0 connector. The only graphics card requiring such a connector is the NVIDIA GeForce RTX 3090 Ti, which also comes with an adapter, but the upcoming 4000 series will need it as well, so it is good to be ready.

These sure are scary units. Seems very stupid to me to only have 2 regular 8 pins in case you don't have a 12 pin GPU or want to avoid problems using the 2 to 4 8 pin. Should be switchable so you either use the 12 pin with 2 8pin or no 12 pin with 6 8 pin or something like that.

Two EPS connectors on one cable is a nonsense downside. Many boards just take the second EPS for no actual reason. The cables can pull a crapton of power that realistically you're not going to run into issues due to even running one EPS cable on an intense overclocking session with very heavy power consumption components. That added with A SINGLE CABLE CARRYING TWO CABLES... is NOT a downside... and why is this dude taking out the primary caps on every PSU? It's not like you can't read the info on them with the things in your face when you open the units up. Unprofessional and lame.

Regardless, these units are still a failure and you wouldn't use this thing with any heavy power consuming components so it's all dull, making the dual EPS on one cable even more of a dull point.

I look forward to GN getting theirs and seeing if it goes kaboom

Some strage cable choices on this one. Especially with how common 3x 8pin GPUs are these days. A 1000W PSU should have enough EPS cables for HEDT CPUs. Should've at least used 16AWG on the dual EPS.

Yes sir like my 750 watt that is on their list but they wont replace it. If it says Gigabyte I will not buy it.

Very thorough review. Thank you.

Would it be possible to put the OEM/ODM in the table on the first page??

 

[Ruru]

It's 2022 and they have a FDD connector in a molex chain instead of having a molex to FDD adapter..

 

[Mussels]

Damn, seems like they still only make average PSU's at best, and explosives at worst



To this day, they're still trying to flog the bad units off here in Au - it's so bad they dont even come with Au power cables
(Centrecom - large chain of stores, also one physically near me)

I cant trust a company that wont even do a recall on exploding units right, and this review doesnt make me think this new model is worth risking especially with it failing the transient load testing... why rush to be first to market, if your product destroys your brands reputation?

For a regular home user sure, but a 1KW PSU can end up powering xeons, threadrippers, and overall powering some really high wattage hardware. In this wattage bracket, you shouldnt cut corners.

If it didn't die on me, the unit is fine. in this regard.

I usually mention the OEM within the first paragraph of the review. Next, I have it in the part analysis table.

I won't buy anything from this brand ever again after their blowing PSU show. I'd rather pay double for a Seasonic so I can have peace of mind.

MEIC? Never heard of that before.

Nothing to complain after many Gigabyte motherboards and graphics cards here. Actually my favourite AIB what it comes to graphics cards.

Going by brand is generally a pretty bad idea -- all companies will sell lemons at some point. Take the Seasonic Focus SPX-750, which bricked itself upon triggering OTP, for example.

Gigabyte will never learn. By far THE most tone deaf company ever.

If they had learned from their eye watering psu incompetence, they would have dropped power supply production immediately and let their brand heal for 5 or 10 years. No sir, not these knuckleheads. They keep right on reminding us that they are the number 1 laughing stock of the tech world hahaha. Hey guys, lookie lookie another hella good psu from yup you guessed it, MEIC! Yeeeehaa!! Who wants to take their rig for a ride?!

According to Wikipedia, George Ripple was an American social reformer, Unitarian minister, and journalist associated with Transcendentalism. Why they used his name on the main transformer is a mystery to me.

You sometimes manage to pull off awkward things...

First of all there is a slash in between the naming, you do not read them together. PDG RIPLEY. PD George is the old name of Elantas. The most important bit is the B-19. It is a trademarked Epoxy resin named Ripley for transformers. B-19 shows the temperature grade krhrmm lowest they have.

If would have guessed why Ripley. If it really ain't the name of the inventor, It would be the maker had thing for Sigourney Weaver covered in Alien slime, that resembles well basically is also a resin

 

[FreedomEclipse]

Just a FYI - it was MEIC that built the exploding ones too...

So it not exploding instantly is a very good sign, but its still made by the same people who made exploding power supplies

How badly do you value your hardware enough to run it through something that could possibly go boom all most have no recourse for compensation when the power supply becomes the destroyer of worlds?

Eh, even the bot Seasonic Gold units will handle your above average gaming PC just fine. Sure, some of them aren't the best... but load testers realistically put loads your PC will never see in a hot box.

 

[progste]

That's a long list of negatives, does this one also blow up?
It's kinda sad how gigabyte can't get their PSUs right when everything else they do is good.

 

[X71200]

They still lack in some other areas as well, some of their boards are still kinda junker. More so than competitors`. They've gotten better recently in some areas, though...

 

[asdkj1740]

the new atx3.0 tests are gold.

 

[juular]

and why is this dude taking out the primary caps on every PSU? It's not like you can't read the info on them with the things in your face when you open the units up. Unprofessional and lame.

LMAO dude ... Take a look at the hole in the PCB where the hold-up capacitor once was again and THINK. Why would an electrical engineer running a PSU testing lab, doing PSU reviews essentially just as a hobby he once started with, spend his time to desolder said big-ass capacitor ? There might be some reason other than to trigger a sense of perfection of numbnuts like you ? Spoiler, there are primary side FETs right behind the main capacitor on most PSUs, which he needs to read the markings on to identify.

 

[crmaris]

I also like desoldering and soldering stuff back together. This way I get lower ripple in most PSUs

the new atx3.0 tests are gold.

You are the first to notice them, so thank you! I had to write many lines of code to implement them in my software and currently 2-3 labs in the entire world run them, only.

 

[progste]

I've had several of their boards and they've been great, reviews and videos I've seen also seem always positive, though I don't know much about their bottom tier boards.
Their GPUs also have a very good reputation.
Lately though they seem to be extending their branding to every component like Memory, SSDs, cases and PSUs and these seem to have been hit and miss, or disastrous in the case of PSUs.

After the exploding PSU fiasco not so long ago, I will not touch anything Gigabyte, especially their PSU. The main issue to me is not so much the failed product, because every company will at some point make mistakes. The main issue is the way Gigabyte handled (or rather mishandled) the issue. Almost a year before GN picked up the issue, I’ve already seen a couple of reviews where the reviewers mentioned about the PSU exploding during testing. What surprised me was that after 9 months or more, I saw the issue being raised by GN. The worst part is that Gigabyte knew there is a big problem with the PSU, but instead of recalling and fixing them, they forced people to buy the PSU whenever they buy a Gigabyte GPU. I don’t feel there is anything wrong forcing a bundle. But it is very wrong to force a bundle on defective products (that are fire hazards), and doing so knowingly. So no more Gigabyte products for me for now.
