    • Great quality and fully modular
This is my first fully modular power supply and it's just perfect, it comes with all the cables you'll need. I used this psu on my 12700K cpu with a RX7800XT and had no issues with power. Everything turned on the first boot and haven't had any issues. I've never seen power supply made by Gskill but I've used their ram and they are always solid and I just gave it a shot to this power supply and so far I'm liking it. ... show more

    • I LOVE modular PSUs
Size: 850 Watts
Super easy to install and the modular design is wonderful. I have so much room for future upgrades. Great performance, quite, and a great value.

    • Rock solid and awesome for the price
For this price the performance can't be beat. Fully modular with easy to maneuver cables and gold rated. You'll be hard pressed to find other power supplies of this quality for this price. G.skill did a great job with this one.

    • Excellent Regulated Power Supply
Size: 850 Watts
Have had it connected to a Gigabyte X670 Aorus Elite AX MB, AMD 7900 processor and NVidia RTX 3060 12GB video card for a little over a month. Been constantly monitoring voltage with HWinFO64 to the CPU, GPU and memory. Rock solid from idle to full load; always within span of <10 milivolts. Quality of the cable ends is impressive... fit snug with no side play, snap in and remove easily at both ends. Purchased this on a rebound from a DOA Enermax PSU which also had ill-fitting cable ends that didn't want to lock, or would lock and then couldn't easily remove. Plenty of supplied cabling for hookups and the fan is quiet. It's a keeper. ... show more

    • Great replacement
Size: 850 Watts
The computer kept turning off. They changed the area where you get the most efficiency. Just keep that in mind.

    • Dead on Arrival
Would not power up at all, completely dead. Also, does not include a cable/connector for the 4 pin CPU receptacle on the mother board, which may or may not be necessary. If unnecessary, both product listing/description on Amazon along with the manual should explain why the 4 pin is not included. I expect better from G Skill. ... show more

    • Resurrected the only computer power supply I ever had die in 35 years of working on computers.
Size: 650 Watts
Quiet, seems to be working fine. I personally would have liked some color coding on teh connector end of the cables to the PS. I was tired and mixed up the board supply and the hard drive's supplies... they connected, just didn't work.
