While obviously you can't really review a PSU fully until you've used it for a few years, as longevity is what you're really looking for, at least in my opinion. However, what I can review is the ease of installation, power provided, and the include accessories and in that department, I'd say this is certainly a winner. Standard mounting holes allowed for easy install to the case (screws being included are a nice touch as well). Included cables seem sturdy, though not braided, I didn't really expect them to be for a psu this cheap though so I'm not taking points off for that. GPU 12vhp cable seems good, better than the adapter I was using before, and was a big reason for the purchase, as I'm terrified of my $800 GPU getting ruined by one of those adapters. And so far it seems to be providing adequate power with no issues during a full gaming load. Seems pretty quite as well. Also, including a 24 pin jumper for testing is absolutely awesome and I can't tell you how much I appreciate that, that's a huge plus for this thing in my opinion. Add to all that the included 10 year warranty, and I'd say overall, you're getting a really nice, high wattage psu for $102 (at the time of writing), and that alone is worth it. The added extras are nice and so far the quality seems solid. Will update if it decides to die within a year or so.

I've been using SeaSonic's 750w psu, but I recently upgraded my rig with more power consumption. When my pc runs really intense work, I realize it is consuming more than 650w. As far as I know, it is the best to match max load of a pc to 60-80% of psu rate. Think about car engine's redzone, you will get the idea. After I replace my psu with this one, I see that my pc's peak power consumption reaches around 710w, which might be not good for the previous 750w psu. It's been working without any noise or system instability. I thing I must note: psu is the most important part in your pc. If it dies, it will likely to kill your precious cpu, mb, ram or gpu. It is not a good idea to cut budget too much for a psu. Still this item has decent price - Around $10 per 100W and 10 year warranty are good deal.

I am using it at the 60% of its capacity. At that range, this PSU is silent, efficient, reliable. I am happy with it, great value for money, looks incredible on my case. The fact it supports atx 3.1 and pcie 5.1 is awesome because of the quality of cables and connectors. And due to the modularity is quiet easy to get it installed.

It does what it needs to do. No issues being on 24/7 so far. My only gripe is that it comes with 2 SATA power cables, and 1 molex (pata) cable. Niche complaint. But for the price, this seems to be a great PSU.

It's a very quiet PSU with a good amount of power. The cables are attractive looking and nicely flexible, with each wire being individually sleeved in a patterned rubber. The exceptions are the 20 pin and the 12 pin GPU cables, which are bundled in a mesh sleeve that is far less flexible. It comes with enough cables to fill all of the connectors. I like the temp sensors on the GPU cables to keep from melting your GPU if the connector overheats. I wish the cables were a little longer though, as the CPU 6 pin cables in particular can be a tight fit in larger cases. My first one ran great running an RTX 4080, but when I upgraded to a 5090 It started shutting the PC down randomly while playing games. Something faulty with one of the built in protections or something. I did a warranty RMA through ASRock. I had to pay for the shipping on the return unit and they don't do cross shipping, so I was out of a PC until the replacement arrived. That said, they sent me a new in box replacement and since they only wanted the PSU back I now have an extra set of every cable, so that's nice. The new unit has worked flawlessly. I have this running a 9800X3D and an RTX 5090 and it works great.

One of the two 12V-2x6 cables that came with the PSU is bad. When the bad cable was plugged in the PC would boot but if the GPU was put under load for 1-2 minutes it would hard shut off the system, with it not wanting to re-start (psu cut out after ~1 second on reboot attempt, looping) until a few minutes powered down OR if I unplugged the GPU it would reboot. Appeared to be some sort of protection working to save the PSU/system from damage, could be a bad thermal sensor in the 12V-2x6 cable (cable was not even warm to the touch). Re-seated cable on both ends 2x, same issue persisted, nothing appears to be visually wrong with it. Swapped to the other 12V-2x6 and the issue went away, ran furmark for a hour then gamed for several hours with 0 stability issues.

The ASRock PG 1600G works perfectly for my setup, mainly because it features two 12V-2×6 power connectors, which makes power management much cleaner and less cluttered. The unit operates quietly and remains very stable under load. If you are running two modern GPUs in your system, this power supply is an excellent choice. The main drawback is its large physical size; however, a system with dual GPUs typically requires a spacious case anyway, so this should not be a major concern.
