PSU headroom if you're NOT overclocking?

[AlexTheTechFreak]

PCPP is saying the max wattage of all the parts I'm looking at is 346 watts. I know when overclocking people like to have around 150 watts of headroom however, if I won't be overclocking anything then a 450 watt PSU should be safe, right? More specifically the system will have a 7600 non-k and a GTX 1070.

It;s not about headroom for overclocking but the quality of the psu mainly. If the psu cannot provide continuous power on the +12V rail then you will have problems even without overclocking

According to users and reviews it seems to be a pretty good PSU but I don't have any experience with Corsair, only EVGA. It's the SF 450W.

I don't see the Corsair SF listed on the Tom's PSU Tier List, but the list doesn't include every psu out there.

Edit: I do see it on the list, down in the "Not Reviewed" category.

YEs it's a good psu, it will do the job.

Found it on Jonnyguru which is a respected site. They gave it a very good rating.

It's a bit costly. You may consider the Seasonic G 450 (Gold efficiency) I have one and it is quiet. Semi-modular, not fully modular if that makes a difference to you.

That tier list is old, misleading, includes many flaws. I discourage using it.

The corsair has been reviewed and is found to be a great unit.

It is always best to use professional reviews, not calculators.

I think the PSU Tier list is a good place to start for someone who knows little about PSUs. Particularly the warnings about the low end ones, and what distinguishes a quality PSU from a low-quality one. But I agree, once you think you know what you are going to buy, pro reviews are the best resource.
