Deal HistoryÂ
Deal History includes data from multiple reputable stores, such as Best Buy, Target, and Walmart. The lowest price among stores for a given day is selected as the "Sale Price".
Sale Price does not include sale prices at Amazon unless a deal was posted by a community member.
This is always $165.....this is just an inflated price so they can put it on "sale" to make you think you're getting a deal. FTC has regulations against this but doesn't enforce it ever. If you need a good sfx psu this is good, just don't think you're getting a deal.
People on Reddit told me to get a 1000W PSU because I should multiply the wattage by 1.5, for some reason, to get the PSU I should get. That makes no sense.

Is that correct?
Probably overkill, but you're in a deal thread about small form factor PSU and the case you selected can use a cheaper, normal sized PSU

It's mainly for the "peak efficiency" of the PSU. Peak efficiency is typically around 50%-70% of the PSU's rated wattage. A good gold/platinum 1000w psu should have zero rpm modes where the PSU wont even spin the fan until it breaks 30%-40% load.
I view this as a few things, Less cost on your yearly electricity bill (although this amount isn't much depending on your kwh cost of your area)
No need or less need to clean the PSU filter which is usually located on the bottom of your case. Depending on how and where you have the computer this can be helpful. For example if you leave the PC on top of carpet but the PSU fan never needs to spin due to the zero rpm mode then that actually isn't a problem. Example 2 You have a lot of pets in the house but since the fan on the PSU doesnt have to spin up you dont have to worry about constantly cleaning the filter.
Transient spikes are the other reason you'd want a PSU to be a good bit higher than your build wattage.
These are more "quality of life" things and not really a requirement for the build. For a 641watt (lets just say 650 watt) build I'd probably recommend a 850w PSU preferably gold rating. The PSU is what powers and protects your whole system so I generally recommend NOT skimping out on the PSU.

Thanks for the info. I was planning on getting a Gold-rated PSU anyway. The Cultist list of the tiers of PSUs got kind of hectic so I just added a Corsair RM1000 when I last posted and stuck with that. I figured the "efficiency" thing you mention would be nice and would give me some room for the cases of transient spikes.
No pets in the house and it will be kept on a desk. Our house is all hardwood so so dust from the carpet. And I'm familiar with cleaning filters since we have several air purifiers, so I imagine the frequency of cleaning the PC's filters will be less because of that.
