Came back to my PC all power is down, diagnose the psu to find it not working at all, seems to be common, as the Amazon page now lists it as a "frequently returned product", which I never would have purchased had this warning been there when I bought it a year ago. Says it has a 10 year warranty but the Pystar page says it's unsafe under windows, when I did finally get to the page there is only a simplistic page with no actual warranty claim information, there is only a small contact page, not to mention I wouldn't want another one of these anyway (replacement). Will update if I get any warranty support but it's not looking good. Don't but this thing, go for Corsair, Thermaltake and spend the extra bucks, save yourself the headache.

I bought this psu because I was low on cash and my previous psu died. Iv waited for quite a bit before I put a review on here. I've ran a 3060, 3070ti, and a 4070 ti super through this thing and it's still chugging. Ive had this thing since May 9f 2023 and it's still working great. Idk if I got lucky (I've seen negative reviews on here) but it's worked great for me.

I bought this to replace a failing PSU and it performs wonderfully. I have had zero issues with it so far and I've had it for several month running every single day. It's a great product at a great price. If you are debating on whether or not to buy this, definitely buy this. You won't be disappointed .

This is a great PSU for the price. It runs very quiet and supports 1000w for a lot of the newer GPUs. It is made of great material and fit perfectly in my case. There are some negative reviews about it not coming with a lot of cables but that's false. It came with more than enough cables for my entire set up and then some extras. There are also some negative reviews about it frying certain hardware but that's false as well. They probably didnt read the manual. Near each of the ports it states what the port is used for (Ex. CPU, PCIe slot, SATA, etc.). Read the manual and youll be just fine. 5 stars for me!

This was a dream. I'm graduating from an old monster 1200W PSU that I had in my full tower case. Unfortunately, that thing was too big to fit into modern cases, especially now they all use that annoying PSU "sleeve" setup inside. So I needed something smaller, and would not compromise on getting something that was fully modular, and had to be at least 1000W because I have the max internal hard drives I can stuff inside my case.This power supply is quiet, the cords and connectors are high quality, flexible enough for good cable management, and tight connections. The back where the cables connect to the power supply are nicely colour coded for which type cable goes where if you can't get a good full-on look at it to read the text labels because you already installed it in the case then realize you want to swap a couple connectors. Not that I did this! ( I totally did this)It's super quiet. I upgraded from a bronze standard to this gold one and my power bill already dropped a bit. I've already had a power outage and 2 monsoon storms and the protections worked perfect. The metal exterior is nice and firm, not easy to bend just pressing your thumb against it. I especially loved that it came with a tester connector that you can easily plug in so that there's no nervous paper clip action going on. Finally, the price is incredible value. I was on the tightest budget imaginable and desperate to get something modular, 1000W, and small enough to fit and this was the best value ever!

Bought the ES1000. So far, it is has been a great PSU! It may not be one of the bigger brand names, but it is still quality built! It has no frills, like RGB fans, which is fine with me because i'm looking for function over form. This was decently priced, given that it's a 1000W PSU (at the time of this review, it was 135.99 with a $40 off instant discount, so like $96).The one thing that I am concerned with is how many cables it comes with. If your running multiple GPUs, then what it comes with won't work for you. Fortunately, I'm only running one 1080GTX because most of my games don't really support SLI, but now I need an extra one of the double PCIe cabled that it comes with because the single one is useless (most NVidia cards now take an 8-pin plus a 6-pin plug anyways). So maybe if they either offered to include two of the PCIe double cables, or create a seperate listing for individual cables so that you can purchase more (it would be nice to have another molex cable than the single cable supplied). There are more receptacles on the PSU than the number of included cables, so it should work.
