The MSI PSU calculator is more detailed then the Corsair calc
(which makes a lot of assumptions for you).

In January I blew up a Corsair RM750x by accident.
Lucky for me Micro Center had the Corsair RM850x on sale for $120.
I was super - extra - double careful when I installed my new GPU in March.
Mmm, just plugged my most recent build into MSI’s calculator.
| part | power |
|---|---|
| CPU | correct at default |
| GPU | off by 50% |
| DDR | off by 3x |
| motherboard | missing |
| NVMe | off by 50% |
| HDD | off by 3x |
| fans | off by an order of magnitude |
| pump | missing |
| USB | missing |
| RGB | missing |
Since it’s an unlit build MSI’s overall total’s off by around 60% before considering USB.
It’d probably be more accurate just to guess.
Thank you for checking.
My intent was just to suggest using a power calculator.
Obviously some PSU calcs are better than others.
I guess the best method would be to try a few calculators and average the results, or use the highest result.
PCPartPicker’s probably about the best one but still full of errors in my experience. Many of the others I’ve found are as bad as MSI’s.
Most reliable method’s totaling up a power column in the build spreadsheet where the entries are measurements from reviews with good methodology (TechPowerUp, GN, and similar) or follow from the components’ specs, including things like USB power delivery. Generally it’s desirable to track both max draw, estimated power in common use cases, and +12 and minor rails for checking against PSU ratings.
Don’t know of any power calculator which comes even vaguely close to that, even though it’s barely entry level for build design.
Eh, if pricing’s anything like where the Thor II ROG tax’s gotten to (US$ 360 for 1000 W) Thor III’s going to be pretty meh.
Hmm, I’m getting zero search hits.
turns out all the modern ones are all actually 200mm… I was remembering the old AX1500i
Wow, that’s so old Corsair’s product page actually has dimensions on it (with their newer supplies they’re too lazy to bother, so you have to check Cybenetics or reviews). Says 225 mm.
