  • Don't be scared off by the price, this is an excellent power supply.
Style: ATX 3.0 & PCIE 5.0 Size: 750W
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. ... show more

  • Incredible for its price
Style: ATX Size: 650W
I have had this product for about 5 months now, it has worked perfectly, it remains stable and has not shown any failure so far, it is a good cheap option for the 650w plus the plus gold that can provide security to our PCs.

  • optimum balance of glitz
Style: ATX Size: 650W
I bought this as a replacement for an old basic PSU included in the case for a custom rack-mount PC. The PC would not power up, perhaps the PSU is bum as has happened to me in the past. A new PSU demonstrated both power supplies are fine. It was easy to check as the Segotep came with a handy tester plug with the "green to ground" wire. Not mentioned in the description and a thoughtful touch. I also admire the packaging. PSUs that I have bought for new PC builds come with pretty elaborate packaging to enhance the unboxing experience, but on the whole, I think the Segotep basic packaging with enough foam to protect the product in transit in a nicely printed but simple box is sufficient. My initial experience is positive, so I am inclined to keep this PSU even though it appears redundant to the original unit. At least it would be an efficiency upgrade, with the 80+ gold rating compared to my no-rating starter PSU. Not a bad thing for a small-case ATX PC stuck in a warm data closet. I chose the non-modular version because my jam-packed rackmount case would block the jacks on a modular design. Testing it "breadboard" shows it is silent. Ironically, I will need to void the warranty to fit it to my jam-packed thin rack-mount case. There is just too much wire to cram around the other hardware. I'll remove the unused branches and cut back unneeded connectors. ... show more

  • Loud
Style: ATX 3.0 & PCIE 5.0 Size: 750W
The PSU works well and was easy to install. The cables don't have the thick mesh covering on them my previous power supply had, making cable management easier. My only complaint is the noise. The fan is quite a bit louder than all three of my GPU fans under load. It changed my previously quiet build into a bit of a nuisance. I needed a power supply in a hurry, and this one was delivered quickly and works. However, I will be replacing it when I get an opportunity to do better research. ... show more

  • Great quality for the price
Style: 850w White Size: 850W-White
No complaints so far, will update if I have any issues long term but so far the 850w white version is great. Not quite as luxurious as my $150 Thermaltake but for the price this brand seems pretty good.
