Gigabyte UD1000GM PG5 80 Plus Gold Fully Modular 1000w PCIe 5.0 Power Supply Unit (Rev 2.0), ATX 3.0, 12VHPWR GPU Connector, Flat Cables, 10 Year Warranty

I bought it to supply enough power for my 4090, as I do AI training locally. It's quiet and reliable, and it can surely work for more than 24 hours under stress.

the box looks and feels very nice. Just buy the box

I have never swapped out a PSU before and found this to be not so difficult at all. My previous PSU was Non Modular and was quite a task to remove, however this one was much easier to work with as it is fully modular, meaning I could focus on one wire at a time. Very easy to install. Delivery was delayed (due to severe weather conditions involving ice, so understandable)

This unit would not power on my PC, I thought this would be reliable, but no, did not operate from the start, reading some other reviews online, a lot of other people have had the issue. Motherboard light would be on, but nothing happens wen pressing the power button. Replaced my old PSU, and booted up fine straight away, so no issues with power switch etc, issue points to the 4+4 Pcie 12v CPU sockets not working.

Very nice power supply, perfectly quiet, the only thing I would suggest is labeling on the cables, the only way to know the pcie from cpu cable is how they split. CPU=8pin(4+4) PCIE=8pin(6+2).

Great psu cables are nice

…the first one arrived without a full set of leads - the CPU power lead was missing. Thankfully, the replacement included all of the specified leads, but it would have helped if they’d been labelled. Works well though.

After installing the unit on my pc I noticed a constant very high pitched sound coming from the unit itself. It definitely was not coil whine I know how coil whine sounds. Does not come with 2 separated CPU cables just one with two 4+4 pin connectors at the end. Really disappointed with this product overall. Had to return in the end the noise was too much. Only good thing was the size of the unit itself it's smaller than my last one.
