Review: Don't be scared off by the price, this is an excellent power supply. - TLDR: Buy this power supply. Excellent quality and will not let you down. Deserves 6 stars for Value for Money Segotep has been around for a very, very long time...Just hasn't been a major seller in the USA for a long time. When I purchased my 750W, it was $130 in June 2020. That's not cheap, but I've seen this go as low as $80 since then on here and that other major PC hardware retailer NE. So if you see it at a low price, definitely snatch it up and don't think you're cheaping out because this, and other Segotep hardware are of very excellent quality. I was inspired to write this review just earlier today during a storm. My main rig with a 5900x and a 6800 XT is running this Segotep 750 Watt PSU (along with a MSI MEG x570 Ace Mobo, 6 Corsair QL120 RGB fans, 1 Cooler Master MF120 ARGB fan, and a Cooler Master Master Liquid ML 360 MIrror 360mm AIO Liquid cooler. Specs listed should be enough to show that this power supply can handle pretty much anything one would want to run in their gaming/streaming/whatever rig with available hardware out there right now with the only possible exception being a RTX 3090 with the same or higher performing hardware, but I still believe this PSU would handle it. Anyway, in my 2nd rig I am running an i7 6900k 8 core / 16 thread CPU, RX Vega 56 8GB GPU, 6 UpHere 120mm ARGB 1800 RPM Fans, and a PCCOOLER GI-D66A (very high performance dual 120mm fan ARGB air cooler rated at 230w TDP). This rig has an Apevia 700W White Essence PSU in it which is a cheap, but decent PSU with no 80+ rating at all. Early this morning we had a pretty major thunderstorm move through which caused the lights to flash off and on a few times, with two of those times the lights staying off for at least 2 seconds if not slightly longer. Both times the lights went off for a couple seconds, the 2nd rig with the cheap PSU in it shut off, but my Segotep 750w stayed alive like nothing happened. This is mostly due to the fact that it's also a switching power supply (this also helps deliver more clean power with far less deviation), but is also a testament to just how good it really is and that it operates just as advertised. I promise it will not let you down. ON top of everything I just said, it is extremely quiet, so much so that I cannot hear it at all. The only thing about it that I'm not a huge fan of are the cables. They're not sleeved, but are the in-line all-black style cables, akin to what cable extensions look like only slightly thinner, but no "ketchup and mustard" cables so they do still look clean. I do prefer black sleeved cables personally, but I am happy to trade that look for the performance and protection this PSU offers. Being fully modular also makes it easy to install. The packaging is also of very high quality with everything coming in thick fitted foam packaging and the Power supply coming in a very nice cloth bag that can be used for other things after installing the PSU. The box is absolutely massive and bigger than most GPU boxes to put in perspective the care they put in to ensuring this PSU shows up without damage in perfect working order. I liked this PSU so much that I bought a 2nd one for the 3800x system I built for a friend of mine when it was on sale for $80. This power supply is unequivocally equal and in some cases higher in quality compared to any other major brand of PSU. Segotep has replaced corsair and seasonic as my preferred quality PSU brand for my PC building business. I included a pic of my rig it's in, though the shroud hides the PSU. Pic is before I added the 6700 XT and has a 5700 XT in it. Edit from the future***. This 750w went on to power the same system , with the additional of a MSI Supr X 3080 as soon as I could get my hands on one. Operated flawlessly, but with all my components plus the new 3080 5900x combo it was touching on 600 watt draw, not spikes...actual draw, during certain uses... I do not just game on my PC and use it for a number of things that require a lot from all the components inside... especially the GPU, CPU, SSD, and motherboard's VRM. So I upgraded to the Segotep 1000w modular gold gaming switching power supply of the same line I'm pretty certain for that setup. The 750w is still going strong... Pushing an Intel i7 extreme 6950x 10 core /20 thread in a system with very similar accessories (360mm AIO, fans, etc) and a MSI Ventus 3x 3070 TI. Even if the PSU had given out by now, in the time I've owned it I would still consider it worth what I paid. I don't see that happening any time soon. My 1000w got replaced already too, but it also lives on in a similar system... I had I swap to a compact 1000w and Segotep only max a maximum 850w (I believe?? I know they make a 750w version,) PSU in their SFX line or I would have brought a Segotep again.
Review: My Own review - For the price of this Psu it works amazing, it is very durable, the cables connected to everything perfectly, it wasn't as loud as people say it is maybe because of the case I picked but it sounded and looks great gives great power and is very durable in the long run

### ⭐⭐⭐⭐⭐ Great quality! Best PSU you can buy for the money right now
*by S***Y on September 23, 2024*

I needed a 700+ watt power supply for my new custom pc. Sadly my old pc had a 600w PSU, and that was not gonna work for my new 7800x3d/7800xt system. I looked at all the options for a 750w PSU, and I chose this one, because of the price and value. I didn’t want RGB and all the fancy stuff on my PSU. All I wanted was a PSU that will work and last for my newly build pc. First off, I want to talk about the Build quality of this PSU. This thing feels solid, and all the connections look very quality. All the cables and wires that came with this PSU also feel and look very high quality. I’ve read and heard many many good reviews with this brand PSU. And I’m glad I bought this one. It works well, i really don’t hear the fan at all, and the temps also seem to be maintained very well. Highly recommend this PSU if you don’t care about having the “gaming” brand PSU, or RGB on the PSU, and all the other gimmicks that really don’t matter. This PSU just works, no gimmicks, it does a great job.
