No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Why not check online for each component for its max watt?
AMD FX8350 is 125W max Xeon E5645 is 80W max
Then the only difference is the motherboard, right?
And also, the Xeon has integrated graphics but the amd does not. If you will let the amd do a lot of things with video, it needs a video card or else the cpu will need to do all of that. On the other hand, if the machine main task is to for example render videos, an integrated GPU in the Cpu will not get you far either...
Max wattage would be under load. OP has said the PSUs are rated for 750 vs 600 (potentially 750x2 if they plug the rack’s second psu in).
That’s your max usage right there. But that’s assuming everything tops out and it’s not a valid assumption.
In any case I suspect the pc will be more effecient on account of the server basically being overkill. Substantial overkill.
I do not agree with that.
A PSU is the maximum what all the components combined are allowed to use. No more power than that is possible. If a system needs more than it's PSU can deliver, it will become unstable (data loss, random restarts, etc.)
The 2x750 is a redundant setup that servers have. Servers need to be able to run 24/7. With redundant PSU if one PSU has a failure, the other PSU will take over. Without any restarts. You can just pull the plug out of one of the PSU and all is just fine.
I do agree with you that the max wattage is under load. Most home servers are running idle most of the time anyway.
that's why there's 2x 750's instead of a single 1500 watt, yes. but they're frequently capable of drawing more than the 750 watts under high demand loads. which is kinda why I put that bit in parenthesis. The OP has said they have it unplugged.
first point is literally what I said.
