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.

camelcamelcamel site will lead you right

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.

100% - go with Seasonic for just a few more bucks and you'll save money in the long run.

Your PC will draw power, as much as it can under maximum load..... "gaming" ...... Is a marketing term and means nothing!

What do you want in terms of efficiency? In other words for example: You spend 1 dollar at 80 percent efficiency,,,, you lost 20 cents in the actual cost to operate. It's not about "gaming" or "editing" or anything like! The only thing you need to ask is how much power do you really need to max out? Then cut that in half for a daily running load, on average. Shoot for 50% load on average if you want maximum efficiency.

With tools.
'Hardware monitor' for example.
Then just read online, basically anywhere I guess?

It's 10 on the CoolerMaster site, but good luck with CM RMA process... I would definitiely go with Seasonic, Corsair or even Thermaltake 10 year warranty PSU over this one. Seasonic and Corsair make it easy to swap, Thermaltake a bit more headache, but CM - forget it.

EVGA is pretty much out of business. If you buy this I would not expect the quality that their products had back in the G1 and G2 period and I would not expect them to be around for any warranty issues. Also the fact that 10 years used to be their standard warranty, dropping it down to three is a sign in itself.

Terrible advice for the average user, stop spreading this dumb crap. The only scenario where this makes sense is a computer running under load 24/7. Otherwise, efficiency drops off much more quickly under 20% than it does over 50%, and modern hardware's idle power usage can drop a 1000w PSU under 10% load. For the average gaming computer, the efficiency saved at load is wasted in idle, making the expense of buying a larger PSU nearly worthless.

Again, terrible advice. ATX 3.0/PCI-E 5.0 PSUs are specifically designed for the power excursions modern CPUs and GPUs can have. They are capable of briefly outputting up to 1800 watts on the 12VHPWR cable. Average max load power draw should be the determining factor in deciding PSU size for ATX 3.0 PSUs, not the transient spikes.

Pretty much this. This is a terrible deal, especially for a PSU made by HEC. Having Best Buy pricematch the MSI MPG A850G to Microcenter for $105 gets you a far better PSU for not much more. If you don't want to pricematch, it's currently $110 at Newegg.

Terrible advice huh? I simply said bigger is better for future-proofing, and bigger is better when cost is basically the same. Not all of us are running ATX 3.0 yet, so my point is relevant and does still stand.

The only thing terrible was your interpretation and comprehension of my post.

Bigger is not always better for future-proofing. Bigger for the same price is better, yes, but show me a good A-tier 1000w or 1200w ATX 3.0 PSU for $110. 850w is good for the vast majority of single GPU consumer CPU builds for the foreseeable future.

Anyone buying a PSU now should be getting an ATX 3.0 PSU, especially where future-proofing is concerned. Bringing up non-3.0 PSUs is irrelevant.

I bought a 1000w 80+ gold Seasonic-made PSU to run SLI GTX 580s and to future-proof. It would shut down while gaming with the RTX 3080ti, but it did last me nearly 12 years. Meanwhile, the 850w 80+ gold CWT-made PSU I just bought runs the 3080ti all day long without an issue. I expect this 850w to last at least as long since I don't upgrade often and generally stay within the same wattage range when I do upgrade. In 10-15 years, a new PSU standard would probably be out anyways, making future-proofing now almost pointless. There's currently the push towards getting rid of the minor rails on the PSU and making it 12v only.

This is a thread on buying a new PSU, not utilizing what one already has. That makes your post all the more useless and pointless.
