Is this a good psu?

[Zev_7]

I recently bought this power supply from microcenter and can't find any reviews on it so I'm assuming it's a new product that was produced recently. It's a Gskill gpx850g, at least that's the model name. Micro center reviews seem good except for one, but I don't live in the area where the micro center is so its not like I can return it if it doesn't work and would have to rely on warranty. 

 

Anybody with this psu and technical knowledge know if it's good just by the spec?

According to the PSU tier list, it's not great, Tier C, and you need to treat it as if it were 230V only, apparently there is precedent for GPX PSUs to stop working if they receive less than 100V while in use.

This sort of depends. It is definitely a good PSU. If you are running an average mid-tier gaming computer, this might actually hurt performance. lower end computers use about 300-400 watts whichmay seem fine since you have more than enough, but power supplies are most efficient at about 80-90% power. The drawback should be slight maybe about 10% worse than expected. Using a pc wattage calculator would be a nice way to figure out how many watts you need. I'd get about 100 more watts than the calculator recommends though just so you have some breathing room in the future. As for the supply itself its rated as 80+ gold efficiency. The efficiency doesn't matter as much on the lower end but a higher one will usually last longer. As for gold, it's the happy medium where it's cheap enough but will last a long time. As for the noise, it should be pretty quiet, I definitely noticed just how much noise a cheap power supply can make when I got a better one. With that change, my wattage went from 700 to 550 and I got that about 10% improvement on my benchmark scores. You say you can't really return it so I wouldn't stress over it. This thing will last you at least 5 years though.

I recently bought a corsair RM750 and the rails seem better on the corsair than this power supply but I'm expecting to upgrade soon. I was worried about wattage with the new parts because they totaled 616 watts and my old bronze corsair 650w struggled with my current mid-high tower pc. 

 

The psus are obv different now.

Forgot to add I have 2TB HDDs now, one 3.5inch and one 2.5inch. The other drives are an sn500 wd blue and an Intel optane stick. I also have a PNY RTX 3080 not asus but should be the same.
