    • SUPER quiet! Changing cables are a MUST
Size: 750W Style: FOCUS GX (new)
I needed another 750W PSU to replace my Corsair that was only two years old and having problems. After hearing nothing but raving about how good Seasonic was, I went for this one. SUPER FREAKING QUIET!!! No, really. You can't even hear it turn on, it's so quiet. Amazing! The instruction booklet was a little vague in that it did not tell you specifically which cables went into which slots...so if you're new to PC building or changing out parts, go watch a video or something. Thankfully, I'm not new, though I still had a couple of problems getting it to function. A couple of things I learned: (1) This includes a tester, which I absolutely love. I read a review or two where they were complaining that you had to hook it up to the computer to test it. This is NOT TRUE. The only thing you need are the new motherboard cable connected to the PSU, the power cable connected to the PSU, and the tester plugged into the end of the cable that normally goes into the motherboard. The booklet instructions are very clear on this. (2) Do NOT fret if the fan briefly spins and then stops when you boot your PC. THIS IS NORMAL. The fan will not spin when the computer is pulling really low power, apparently. (3) Replace EVERY cable in your computer with a cable that comes with the PSU (if available). I am not jesting. Do it. Why? Because I found out the hard way (hours later while breadboarding) my peripherals (a CD and DVD drive) were causing my PC to not boot... They were working just prior to changing out the PSU... but because I didn't change out that one single cable...it kept my system from booting with the new PSU. (4) If you have to troubleshoot, the booklet is not really going to help you much. If you've already checked to ensure all cables are very securely plugged in... Try breadboarding. It's what helped me find my issue. (5) If you're running a PCI-E graphics card (you know, one that isn't built into your motherboard, take the recommendation and use TWO/THREE cables instead of one. The booklet talks about it, and it's really clear on this point. No, really. Do it. Overall, I'm very happy with my purchase thus far. Of course, this is just day one, but it's already much quieter than the Corsair ever was. People were right about Seasonic. Great product! ... show more

    • Stable, well-built power supply
Size: 850W Style: FOCUS GM (new)
We live in strange times. At the time of writing (July 2020), It is NOT easy to find the power supply you want! Sometimes you see a power supply you like and by the time you double check out the specs and add it to your cart, the item is no longer in stock! To be honest, I accepted this power supply reluctantly. I wanted a fully modular one and this one is only semi-modular. But I did want a Seasonic brand because of their reputation. Anyway I used this power supply to do my build and here are my thoughts about it. The first great thing about this power supply is that it comes with a tester. You simply plug the power cable of the PSU into a wall outlet and then you connect the tester to the 24 pin cable that goes to the CPU. If the power supply is working this will cause the PSU fan to spin. This is a great stress buster. It saves the grief of putting together a build and then wondering what part is not working! Is it the CPU? The motherboard? The PSU itself? We have all been there. Hats off to Seasonic for this. The PSU comes with 1 24-pin CPU connection, 2 4-pin connectors that can be used together if your motherboard has an 8-pin connector. It has a bunch of 6+2 pin connectors also. All of these comprise the non modular part and hence you must find some way to keep them out of the way in your build. I just used the supplied ties to lock them down at the base of my computer case. There are more than enough cables for PCIE and SATA connections. You are most likely not going to use all of them. Installing it is a breeze and the instructions are adequate. The fan is quiet. My system is stable. The PSU is 80 Plus Gold rated. The build quality is solid. I would recommend this power supply even if it is only semi-modular. ... show more

    • Good PSU, but it came at a cost much higher than I expected
Size: 850W Style: FOCUS PX (new)
Update on performance: Working solid and been on 24/7 for 2 months. No issues with power delivery for my 1080ti. The product itself is a 5 star psu. Still a bit salty, but I would recommend. --------- First off, this review is a bit biased. I bought this psu to relace a cheap no brand psu that was powering 2 ssds, an 18tb platter hard drive, an i5, and a 1080ti. The case is a htpc case, so not much room on the inside for any excessive cabling. I spent a good hour routing cables and plugging everything in. Then I attached the power cable to the wall and hit the power button... nothing. No indication of power at all. I followed the very limited instructions, but it would not power on. At this point, I wasn't sure if it was DOA or if I maybe made a stupid mistake plugging things in. I spent another 30 minutes undoing all of the cable management and checking everything. It turns out that for some reason if I plugged the 1080ti with 2 seperate 6pin power connectors, the psu just would not turn on. I tried one cable that has two 6pin connectors on it and although not ideal, it powered up. After another 30 minutes of rerouting the cables, I powered it up and loaded windows, but the 18tb hard drive with all my roms and games wasn't showing up. Sure enough, due to a lack of flex in the power cable, it completely broke off the backing of the sata power connector on the drive. I know I shouldn't blame Seasonic for that, but if it had just worked the first time in the configuration the manual stated, this would not have happened. Incidentally, to change out the power supply now cost me over $670. Needless to say I am salty. Maybe add a power indicator led on the psu and make the included manual useful. The amount of time and unnecessary moving of cables in tight spaces could have been avoided. Again, I can't say I blame Seasonic for this, and the power supply is excellent otherwose, but in 25 years of working with computers, I won't forget how angry I felt when I discovered the broken Sata power plug on that hard drive. ... show more
