OEM is Channel Well Technologies. They are a MAJOR OEM who also make Corsair's RMX 850w. Product itself reviewed well, but was subject to US tariffs making it's price higher than it should be. That said it doesn't have as much brand tax as others.

Bought this last November for $87.19 on sale from Newegg. So far so good.

It's worth highlighting the 10 year warranty. I've had cheap power supplies fail on me, which is annoying when they're $30, but pretty frustrating when they're $100. I've been using the same high-end power supply for 12 years without any problem.

Would you say this is on par with the Corsair you mentioned?

While a long warranty may be an indicator of quality, the big question is how much of a hassle is it getting the warranty honored. And in case of bulky/heavy items, if you have to pay to ship it to a repair facility, the cost of shipping alone may make a warranty claim too expensive, or more expensive than buying a brand new replacement product. Anyway, just something to keep in mind.

This is a great power supply. I have it powering a 5900X and 6900XT setup since last August. I paid 89.99 for this on last prime day

Yes it is. Both this and the Corsair are Tier A

Yep, but like the poster below you mentioned the warranty support may or may not be. A lot of ppl claim Corsair's warranty support to be pretty good, but I can tell you 1st hand they did not stand behind their warranty for the A500 cooler. That whole disastrous product got swept under the rug.

Another mention of poor Corsair support here. Bought a case, terrible fit and finish, customer support was awful on getting replacement parts. Never again.

I went ahead and bit on this. I've been shopping 850w power supplies for a few weeks. This is a pretty good deal for an A Tier power supply.

Looking for a psu for my new build…this might be it. Just missing case/psu at this point for it to be a buildable rig.

Anyone know if you can get more sata cables? Cablemod is custom only, and thermaltake's own cables don't list this PSU as supported.

If you can hold off on building for 2-3 weeks you may get a better deal on prime day. Still a good deal at 109 but just know I paid 89.99 last prime day.
