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 MoneySegotep 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.
The Solid Rock! Trust and Stability
After three years, I give it 5 stars without hesitation, and it’s a component I would buy again with my eyes closed.From day one, it has powered all my components flawlessly. There have been no fluctuations, strange noises, or any signs of instability.The efficiency is noticeable, which is vital for keeping my system running and ensuring that power is delivered as cleanly as possible.The PSU is extremely quiet, even under heavy load. It just does its job without drawing attention to itself.If you are building a mid- to high-end PC and are looking for a power supply that gives you complete peace of mind, is reliable, and can handle hard work without any problems, this is an excellent investment. It is the foundation that allows you to use your other components with complete confidence. Highly recommended!
Great power supply especially for the price I reccomend
So amazing I had to order it twice. The cable quality is good however the case size didn’t fit into my Foifken m1 I don’t know if it was a case problem or a power supply problem. Nonetheless it still worked flawlessly and produced a minimal amount of sound.
Good
This is a great power supply for a decent price. It runs cool, quiet, and stable, and the fact that it’s modular for this price is a great bonus. The cables look nice and don’t have the ugly ketchup and mustard colors, they’re a nice solid black. I’d never heard of this brand but after some research learned they are considered a decent b tier brand, and I’m glad I took the chance on them. If you have any hesitation, take the chance, I don’t think you’ll regret it, this power supply has been great.
It worked well for a long time, but it eventually needed replaced.
It took me a while to get around to it (about 6 months), but I’ve finally managed to install this power supply into my computer. It was easier than I thought it would be and I enjoyed doing the work. Originally, I had installed a THERMALTAKE Smart 500W 80+ White Certified PSU which was simply a cheaper one which I had purchased which was compatible. It took me under an hour to install the SEGOTEP and I am pleased with the results. I do not overclock, but I am more comfortable having a power supply which is more suitable for my specific build. I like how it’s fully modular which allows for better cable management.Before installing the SEGOTEP I completely disconnected the old power supply, removed the four screws and I then removed it from the case. I took a good look at all of the connections included with the new power supply to decide what I needed. I only needed the 28-pin, one 8-pin PCIE, one 6-pin IDE/SATA and one 8-pin CPU cable. At first, I assumed that I needed the 12-pin for something which I wasn’t sure of, but I quickly realized that it was only required for PCIE5.0 graphics cards which I do not have (I have an RTX 3060 which requires the 8-pin). Unfortunately, I had already secured the power supply with 4 screws and plugged in the 28-pin, which was very difficult to remove, and which was in front of the 12-pin, so I had to remove the 4 mounting screws and displace the PSU in order to remove the 12-pin. Overall, cable management is much better since completing the installation.While I was at it, I decided to properly connect my Wraith Prism CPU cooler to the motherboard using the RGB cable which I found in my motherboard box (which I had originally overlooked). I also connected the front 3 fans of the case (CORSAIR iCUE 465X RGB Mid-Tower ATX Smart Case) to the lighting node core in the correct order and plugged the respective SATA power cable into the power supply. When I built the computer in late 2020, I wasn’t sure exactly what the lighting node core was nor what kind of connection it had, but it had become apparent to me that this is a SATA III power connector. Initially I had also overlooked the second M.2 slot which now holds a 1TB M.2 (both SSDs are identical). Eventually I had even replaced the rear and top chassis fans, which had static blue LEDs, with 3 new matching ARGB fans for slightly improved cooling and more control over the lighting effects.All of my LEDs now function properly and I am now able to fully customize the LEDs of the 6 fans, the ASUS TUF Gaming LC 120 ARGB, the 4x16GB CORSAIR Vengeance RGB Pro DDR4 and the motherboard (ROG Strix B550-F Gaming Wi-Fi). The lighting effects which are available with the Armoury Crate and iCUE software are heavily customizable and are very appealing.Altogether, my computer now seems to be much more complete.EDIT: I was experiencing a lot of crashes so I contacted a professional who referred me to a gentleman who offered a very good price for fixing my computer. He rebuilt the computer and only the PSU (power supply) needed replaced. He didn’t explain in detail exactly what was wrong with it (aside from bad thermal paste, poor cable management and the faulty PSU) but with the new configuration I have had zero problems. The new PSU is a MWE GOLD 850 V3. I was also informed that my configuration is RAID compatible so during reinstallation of Windows 11 I installed it with a RAID configuration by changing a few UEFI/BIOS settings and installing RAID drivers during initialization of Windows.Thumbs up.
5 stars because it works. My computer was damaged by a nearby lightning strike. I guessed that the fact it was dead was caused by the original power supply and I was right. Never having replaced a power supply I must say that it was easy to install and hook up and I once again had a functional computer. Very happy. Yes I have replaced all surge protectors.

Failed just before 6 months old. Not impressed will stick with branded products that have a 12 month warranty.
