Great. Does exactly what i needed it to do. Easy to install as well

Old power supply finally gave out on me after 6 years, so I needed a replacement. This one has been doing spectacularly so far, I’ve had it for about a year now and it’s still going strong. I also think 850W is ideal for upgrading over time, because I just got a 5070 for Christmas and will have plenty of power to run it when it’s installed.

Had to buy this off of a whim as previous power supply shorted, this one exceeded my expectations, decent price, a silent fan switch, the modular cords are handy, and haven't had any issues after a month of use.

Got this power supply becasue my old 600w couldnt handle the new setup. The price of this is great and so far gas been reliable and ive had no issues. Its also great that its modular, making cable management a breeze. I would recommend to anyone building a new budget pc as the value for this is unbeatable for the power output.

Bought it on cyber Monday because I needed a new power supply and this one blew me away it was budget friendly and it solved my computers issue of shutting off when a game drew too much power I say this is better than most Pricier power supplies

Best buy had this easily available on the shelf when my prior PSU went bad on my 5 year old PC. A couple of employees helped make sure I was buying something similar to what I had previously in my set-up. Works great and came with all the cables needed to plug back in and get back to work.

The Thermaltake Toughpower GF A3 850W is an outstanding power supply. It delivers consistent power with the 80 PLUS Gold certification, ensuring efficiency even under heavy loads. The fully modular design makes cable management easy and clean, while the PCIe Gen 5 and ATX 3.0 compatibility future-proofs it for modern setups. It's quiet during operation and stays cool, even when gaming or multitasking. Overall, a solid choice for gamers or anyone building a high-performance rig. Worth every penny for reliability and performance!

Had bought a different power supply but it wouldn't work with my case. Good thing they had this in stock at my local best but. Fully modular, has the new power connector for Nvidia graphics cards. 850w good rated. Quiet.

Great product. Nice and quiet and stronger than my last one. Thanks to the Geek squad for getting this done in 48 hours and minimizing my down time!

Not sure I’m the best person to be rating this because I’ve never built a PC before. Replacing my old one with this one was a bit of a challenge because a few of the cables looked exactly the same, but we’re definitely not interchangeable. Product itself seems to work well. Sometimes my computer doesn’t go into sleep mode fully now and I have to flip the switch in the back and then when I flip it on it just automatically turns on instead of needing the power button pressed. Not sure if this is to do with the PSU or my motherboard or something else. I’m using an Asus ROG prebuilt if that helps anybody.

My old power supply died and I needed a new one fast. They had this in stock and I was able to get it the same day. Haven't had any problems with it.

Nothing crazy to say. I like the fan, and the full modular capabilities. That way I don’t have a ton of cords in my case taking up space.

Works great for my build easy to install and set up

Recently upgraded GPU and needed a new PSU. Worked amazing for my new 5070 ti.

Love the silent mode can't even hear it! This brand is really starting to impress me.

Works good ! And powerful ! Enough for my pc no problems

These Thermaltake Toughpower GFA3s are good units, The first Toughpower I ever used was a Toughpower GX2....2 years of daily use and its still running like a champ. Another system is on 3 years and again, Running beautifully on its Toughpower. Just slapped this one into another rig and I expect it to last forever because these things are just solid all around, They have Japanese capacitors, They meet the latest standards for PCIE. It meets 80+ Gold AND Cybernetics Platinum. Overall theyre well built supplies. You wont regret getting a ToughPower unit for your system. Oh, Also. 10 Year Warranty. Fantastic.

Silent. Dependable. Reliable. Zero complaints. Is a great deal.

Exactly as described no issues. Couodnt ask for more.

My 3yr old PSU died (assuming due to surges caused power outages). I picked this one up, installed it, and it's working like a dream. It's also quite a bit quieter than my previous one
