Great power supply! Seasonic is an awesome brand. I have black/red cable extensions to fit the look of my build, but even without those extensions the cables are still decent looking! The little 24pin adapter thing to test if the PSU works is an awesome touch and is something I didn't have in my previous power supply. Overall a great power supply that is very easy to work with!

I just built two gaming rigs for my two brothers, and both PSUs failed. One failed a month after purchase, the other failed two months after that. Had to RMA both of them. I have several cheap PSU manufacturers that have yet to fail on me. Greatly disappointed with Seasonic and their poor production quality and lack of good QA. I had grown to know Seasonic as a big player in PSUs, but these quality issues have made me want to never buy from Seasonic again.

This is an excellent 750W 80+ Gold PSU for the price. Semi-modular cables are great for modern builds that don't have many components that need dedicated power. I do wish the modular cables had the same mesh wrapping that the non-modular 24 and 8-pin cables have, as I think that looks better on the PCIe power cables, but other than that it has given me no problems powering an RTX 3080.

I did not expect was for this PCU to basically render my pc useless. Fortuntely, I still have my old 550w PSU because they sent me a DEFECTIVE POWER SUPPLY. I connected everything to my motherboard and I made sure everything was plugged in correctly. I am using the same motherboard, same gpu, same cpu, same everything. Upon powering on my computer, the lights will turn on and the fans will spin, however, it leaves a "DRAM" troubleshooting led on my morherboard. I did not change my ram whatsoever, so I know that my ram was compatible (I had it working fine in the old PSU). I even troubleshooted it by making sure the ram was pressed all the way in. When that didnt work, I took out the ram and tried only using 1 stick as opposed to my 2x8gb sticks. When that didnt ... MoreI did not expect was for this PCU to basically render my pc useless.

I did not change my ram whatsoever, so I know that my ram was compatible (I had it working fine in the old PSU). I even troubleshooted it by making sure the ram was pressed all the way in. When that didnt work, I took out the ram and tried only using 1 stick as opposed to my 2x8gb sticks. When that didnt work, I tried the other stick. Still nothing. I even went as far as to use another DDR4 stick that I had stored away which I know for sure worked on this system. Again, nothing. Just in case it was the CPU, I removed it, I checked the pins, everything was fine. Reapplied thermal paste, and put it back. To my dismay, there was still no display on my monitor. To make sure it was not the GPU, I tried moving my display to my motherboard but I still did not get an image. So frustrated with this product. I did everything to troubleshoot my computer. I even cleared the CMOS to bring the bios back to default. Still no display.
So far so good. With my 600w psu I was having PC restarts, only one stick of ram was being read, and usbs occasionally did not work until pc was restarted.Easy install.SpecsRtx 2070sRyzen 2600x16 gb Corsair VengeanceASUS B450 ROG strix1.25 TB SSD
Great little power supply. It's really quiet, even under a hard load, pressing the system with Prime 95 with AVX instructions enabled.Cables included are adequate for most PCs, although if you want a full two, 8 pin connectors, for the CPU power, on high end motherboards, you should check out other power supplies.For 99% of systems though, this will be a great PSU.If you have an extra large tower, you may need a cable extension or two, but for the average case the included cables are plenty long.
Purchased for my in-law’s build. Definitively overkill without a dedicated video card. It’s Seasonic and gold. This unit should be quiet and reliable for years.
Great power source!I bought this to power my new build up,Asus TUF X570 MoboRyzen 5 3600Asus Rog Strix 2060 SuperWater CoolerCorsair 4x8gb RAMAnd this thing so far has ran like a champ. I do have to say that some of the wires that come with it in the box were a bit confusing but it was my first build so take that with a grain of salt.The PSU is pretty small in my opinion but the fan is extremely silent. I haven't had any problem with the PSU dying me yet, I've had it for about a month or two now.
I purchased this 750W Seasonic power supply after over 10 years of faultless performance from a 620W Seasonic Power Supply. This unit provides stable and efficient power. The build quality of the unit is excellent and the semi-modular format is great for reducing the amount of excess cables that must be hidden away in your case. I have no hesitation in recommending Seasonic products.
I have been using this power supply for about 2 weeks with no issues. SeaSonic is arguably the best PSU maker out there. The size is right, the cables are long enough, and my build went smoothly.I have never purchased a semi-modular PSU before. It seems to me that you either need full modular for your build or you don't. This PSU was at the right price, so I gave it a try. The fixed cables are for the two motherboard connections plus a double PCI cable. Those are the only ones I needed for my build thanks to an M.2 storage drive. I got the declutter benefit of full modular without paying the premium price.
