Customer Ratings & Reviews

Works great and is very quite and good for the price. Also gives good room for upgrades in the future which is nice

The Thermaltake Smart BM3 850W PSU is a reliable choice for modern systems, featuring 80+ Bronze efficiency for energy savings, PCIe Gen 5 and ATX 3.0 compatibility for next-gen hardware, and semi-modular design for better cable management. Its 850W power capacity ensures stability for high-performance builds.

Works great with my older gtx 1080 and liquid cooled i9, was getting random shutdowns on pld PSU after swapping from a gtx 960

Make sure to get an unopened box... Works with my Asus X99 MB (2014) and NVIDIA GeForce RTX 4070 Ti Super (2024) gpu. If all of the cables were included I would have kept this in my setup but it was missing 2 runs of sata cables and had 1 extra run of molex. The box was apparently an open box as one end of the plastic was missing but I didn't think anything about that.

I know it’s bronze but I’ve had this a couple years now & it’s worked great. I’ve used it with a handful of gpu’s and a couple different CPU’s. Worth noting it ran a 4080 and a 9070xt amazingly as well as a 10700k and a 14900k beautifully. No issues highly recommended.

Was put into my husbands PC that came from the UK. We had to swap the power supply to match the USA outlet voltage. Has been great and works amazing.

Power supply has more than enough juice for my mid / upper level build. It's super quiet with great build quality. I picked up on sale and glad I opted for the Semi-Modular design. Way cleaner cable management

Works like a charm. Have it installed with my 7800X3D build.

Very solid beginner choice for a pc, good price, very silent fan, and comes with everything you need and more, definitely recommend.

It was a great flexibility replacement for the original one for my gaming console computer.

This psu made my first pc build so Much easier and faster. I would recommend this for any body I had it for about a month and I did not have any issues.

I like the price and the product the reason I pick up this power supply is for the PCIE Express 5.0 one cable direct connection to my 4080 Super RTX

Good PSU. Comes with plenty of cable options. Your 24 pin and CPU power is built in.

Have a $75 gift card. I was trying to burn. Don’t really need it. It’s OK.

didn’t even own it for 30 days.. NOT EVEN 30 DAYS. today was the 28th day I owned this product and the power cord got so hot it burnt straight through and started sparking nearly electrocuting me. There’s a burn mark on my carpet, and if I wasn’t there when it happened it could’ve easily burned my house down. Do not buy this product.

Upgraded my graphics card so needed additional power. Easy install and I love the modular nature, so there are fewer cables clogging up the guts of my PC. Works great.

I bought this as the cheap thermaltake with only 500w was having some issues with a video card. This one I liked so much better as it had tons of power, worked well and also was semi modular. With the other unit I have cords everywhere, this one allowed me to not use some of the cords I didn't need. This one will be so much better when I build another system with a better video card also.

I’m currently running this power supply with a pretty demanding setup — AMD Radeon RX 9070 XT, AMD Ryzen 7700X, and 32GB of RAM — and it has been working perfectly. The PSU delivers stable power with no issues at all, even under heavy gaming and multitasking loads. One thing I really appreciate is how quiet it is. There’s basically no noticeable fan noise, which makes my whole setup feel smoother and more premium. The semi-modular design also made cable management much easier, and installation was straightforward. Everything feels solid and well-built for the price. Overall, this is a great value PSU that handles high-performance components without any problems. Definitely recommend it if you’re building or upgrading a gaming PC.

Due to upgrading my GPU (RTX 5070) i needed a new PSU. I wanted something i considered affordable but at the same time wouldn't run into any issues with powering my pc. I landed on this PSU due to it having be semi-modular. If you're looking for something that has modular capability but runs cheaper than competitors this is a solid option.

Very quiet and stable, comes with a lots of cable and longer mother board cable. PCI-E cables save me from chaos.
