Price is good, just make sure it fits your needs. All PSU's run at peak efficiency right around 50% load. So this is rated to be 80+ gold and is therefore expected to be 90% efficient at 50% load with a power factor of .9.

Efficiency will drop on either side of the 50% mark.

So if you are concerned with efficiency, make sure your total average load is 425 watts. The latest Intel 14900 chip can pull that much power by itself if you let it run without limit. Just be sure you know what you really need to power your system at it's maximum, and then choose a PSU based on 50% of that number for peak efficiency.

I have a 1300 watt platinum rated PSU in my rig because when it's crunching number under normal load, it's eating 600 to 700 watts continuously. I paid enough for the pieces and parts in this thing, I don't want to waste any in my electric bill.

All of this is just food for thought. Cheers 🍻 and good luck

It's never been 170.00

It's been 110 most of Feb. It jumped to around 140.00 for a couple of days. Then dipped to this price.

The markup and then drop is a common thing to make the sale price look better than it is. If they sold any at the 140 price then they sell X amount at 99.99 price.. it averages back out to the month long 110 price.

That is good advice from an efficiency standpoint. But some of us would argue that overkill prevents unnecessary issues (power spikes on 3090s for example), and is the key to future proofing. It all boils down to the best bang for the buck. If you want cutting edge stuff, 850W is arguably too little anyway. My old EVGA 3090TI Hybrid specs 1000W as the minimum if using the 12VHPWR cable (425W TDP). I basically ended up saying screw it and got an EVGA 1600T2. I'm good for 10 years under warranty, have the most efficient rating, and never have to ask if I have enough power again. But I did get it for a steal ($233.99 brand new). It just made sense. So what if I'm losing a bit due to it being over-capable. My point is, if a 1300W Gold comes along that's the same price as this, it makes more sense from a future-proofing standpoint to go bigger instead of splitting hairs calculating where you'll save $0.12/year on efficiency. Again, not saying it was bad advice, just saying bang for the buck is the ultimate factor.

From feb 1 to feb 20 the price was $110, but before that the price avg was $140. $100 is a pretty good price for an 850w gold rated EVGA PSU. The only downside is the 3 year warranty on this particular model

I've had so many PSU failures over the years, which is why I always go with brands like Seasonic who offer 10-12 year warranties. Companies don't do that if they don't believe in the quality of the product and intermittent PSU failures are one of the worst issues to troubleshoot.

Oh yes, It's always about the best bang for the buck!

I went the long way of describing/saying that in my initial comment.

Considering a 750w supernova was costing more than this for over a year, I would consider this a decent deal
