  • i should it had listen
Size: 450W Style: P
i have more than 25 years of experience building computers, not just regular low budget affordable pcs but high end extreme systems, i bough this power supply and i had it sitting on the box waiting for all the parts to arrive to finallly build an office system, when i finally recived the last part today after i installed everything, surprise, no post, put and old generic power supply and system post, so i replace and old power supply that works for a new power supply that doesn’t work, how nice edit update seller offer a full refund that might sound good right? except that what are the odds of 2 diferent motherboards burning the memory modules what they have in common? well i installed the power on a new build and it burned my ram don’t think i made a mistake, it was 2 brand new modules so i went and got the system that i was using previously before the new parts arrived for the new build that system was working perfectly fine for months guess what i just try the power supply in that board and it also burned the ram on that board i went got another pair of ram change the gigabyte power supply for the old one everything works is not a faulty product, is really a bad product no doubt not worth having a product that can damage your expensive computer parts ... show more

  • Wires Cables and Cords
Size: 450W Style: P
Wires Cables and Cords. Not sure why there is no pictures of them but here they are all in their glory. I forgot to measure the length but for me they were plenty long enough. I have an archaic system with 2 SATA drives and a DVD burner so there were a lot of cables left over that zip tied and tucked away in a cubby hole above the drives. I was getting BSOD with so many different errors I knew it was hardware and decided to start with the power situation first. So far so good. This thing is either real quiet or my other one was loud but I can not hear anything at all down there. I think I am going to order another one to park on a shelf just because. Now to look into surge protectors since mine obviously is not doing it's job anymore. ... show more

  • So Far So Good
Size: 450W Style: P
What can you say about a PSU. It works, it did not catch fire and the fan noise is very low. I used it in a mini-ITX Ryzen 7 5700g build and it is really a bit of overkill. But it was available and not at a a premium price. Nor five stars because the price for a PSU like this to get five it would also have to be cheaper. ... show more

  • READ BEFORE BUYING - HORRIBLLE EXPERIENCE
Size: 850W Style: P
I picked this power supply up with high hopes for me first ever computer build. Let me tell you, this experience was anything but enjoyable. This had nothing to do with product defects, but everything to do with how the manufacturer made this product. This is a fully modular PSU, but I had a MAJOR issue with it. To start, the PCIe cables that are included in this package are either daisy chained (1 cable into the PSU, 2 PCIe out) or an 8-pin that is 2x 4-pin connectors slid together. For my GPU(I have the 3080 Ti which has 3x PCIe ports), the PCIe cables that were not daisy chained would not even fit into the power ports due to the fact that they were 2x 4-pin connectors put together. The daisy chained ones fit just fine, but they're not recommended for GPU use by users, the manufacturer, and cause a decrease in performance. Even with that in mind, it wouldn't be a good idea to leave an odd one out because it would be an extra risk. After all this I still had some hope, but that didn't last long. I decided that I would just purchase new PCIe connectors since this is a fully-modular design. I was wrong. Gigabyte doesn't sell any replacement cords and there were no 3rd party sellers that have them either. I just couldn't believe it when I saw this for a fully modular PSU. If you're not going to be building a newish gaming computer or are building a system without a GPU (not sure why you would be getting an 850W PSU then), then this would work out fine. On the other hand, if you are DO NOT BUY THIS. It'll save you alot of time and keep your blood pressure where it needs to be at! ... show more

  • Bought as a replacement after failure of 2 EGVA PSUs
Size: 850W Style: P
Not much to say, originally ordered 2 EVGA modular PSUs first one fried in a few months, and the second one the fan bearing exploded after about 6 weeks. (only time I could say the magic smoke escaped from a system I owned) Needless to say, I was done with EVGA not saying they are a bad company or other products may not work great but I did not have much luck with their PSU what luck I did have seemed to be bad. My gigabyte PSU has been running problem-free for about 6 months and would recommend it to anyone building a new system or who needs to replace a failed PSU. ... show more

  • Stays COOL to the touch and super QUIET
Size: 850W Style: P
This power supply is absolutely amazing. After almost 5 years of owning my power supply, it had gotten loud and was getting unbelievably hot anytime I started gaming. As soon as I swapped this one, everything changed. My whole build is really focused on being quiet, and the last thing that was still super noisy was my old power supply. This guy is completely silent and literally runs ice cold. I'm so impressed I've recommended it to my brother as well since he was looking for an upgrade. And the price is really really good too for a Gold rated power supply. This is my new main power supply recommendation. ... show more
