it looks great, but the inside and passive radiators seem like a heat-trap. it will certainly take a considerable time to heat up (so much water and all that), but this thing will stay hot for a long time.
Is it just me being out of date (been a while since I built a PC) but is a 400W PSU a little tight and potentially going to be pushing said PSU to the limit far too often?
They're really 600+ W power supplies that have been de-rated due to the higher expected operating temperatures in the Corsair ONE. They aren't going to burn out easily. Higher wattage might be warranted in a larger machine that could have more power-hungry components added aftermarket, but these PSUs are plenty for what actually fits in the Corsair ONE.
Linustechtips built a small form factor PC with the same specs (plus they OCed the CPU) and used a 300W PSU. Even when gaming not all parts are pushed to their max power draw. A 400W PSU should not have any issues.
Current Gen GPUs are a lot less power hungry than last-gen ones were.
The 1080 TI has a 250W TDP, the 7700K 91W those are the only big power draws in this system so it should be just fine. Now if you were building a system yourself, you might want to put a little more capacity in there for future expansion, but OEMs don't care about that and will just spec a PSU for the components they ship in the system to save a few bucks.
Power supplies are generally not efficient at power draws 50% and below of their maximum rating. Power supply efficiency tends to increase towards 80% of maximum rating and then falls off a little, so it is better to match your power supply to expected power draw. eg installing a 600W power supply when you're only expecting to draw 300W is wasteful of energy and $.
The only PSUs that have their efficiency peak around 80% are some fanless ones that are made by derating significantly more powerful fanned models. Anything else will peak around 50% and have good efficiency from at least ~20% load. Below that's generally more miss than hit, only the latest 80+ spec (Titanium - 90% efficiency at 10% load) has a requirement below 20%; most other PSUs fall off the cliff somewhere below that point as components with a fixed power draw dominate over those whose power consumed is proportional to the output. Even derated type fanless ones will be reasonably efficient at 20% because they need to be to get an 80+ rating; although the shift right in the 20% level means that they normally end up with a lower 80+ ratings than their base models or efficiencies at load would suggest.
overprice pre builts as usual. nothing to see here folks just a company trying to scam suckers. go find someone who is more than willing to give you the same specs and build it for you for way less than that.
Of course - I just purchased the old one. Support has been "iffy". They have a 24x7 phone support line, but that's pretty much level 1 support. I submitted a ticket through their support site and I'm still waiting for a reply 3 weeks later. My ticket? I'd like to have a manual maybe?

It looks great. Just hate the "ONE" branding. Ridiculously cliche.marc1000 - Sunday, August 6, 2017 - link

There's a 600W passive power supply on the market now so perhaps system builders like Corsair will switch to that.lioncat55 - Saturday, August 5, 2017 - link
