Hey everyone, I need to replace my power supply since my 7 year old HX850 is acting up ( I think). Looking to replace it with one of these two. Not sure which one to get. I do love they both have a 12 year warranty.
My PC has been resetting during games. I've run stress tests and they all seem to pass. It seems like either the CPU or GPU or both aren't getting enough power under load.

That's not possible unless you haven't updated your sig rig to reflect some change to like two heavily overclocked GTX 1080 Ti cards or something like that. All I see is a 3930K and a GTX 1080. That's not even enough to saturate a 650W PSU. I'd even wager that a good quality-made 550W PSU could handle it.
So, I say it's just not stable. Perhaps your stability testing methods aren't sufficient. What all have you done precisely?
I've run prime95 and furmark a few times for about 30 minutes. Also ran memtest. Resets during Mass Effect Andromeda during the load screen. Reset during Ashes of the Singularity after about 2 minutes in game and it even reset during simcity. I suspect my PSU is degrading.
Prime95 for 30 minutes is about as effective as nothing. Even if you ran it for 30 minutes every single day, that's still the same as 30 minutes just once, which is nothing. Prime95 needs to be run for several hours (all in a row, no stopping) because it must get through ALL of the different FFTs that has. The Blend test, which is what you should be using, has about 82 different FFTs and at 3 minutes per FFT with several seconds pause in between each (that's normal), it can take 5-7 hours to get through all of them. At 15 minutes per FFT, it can take about 24 hours.
You see, Prime95 is not putting a constant unchanging load on the CPU. If it were doing that, then it would be the least effective stability test in existence. Each FFT makes the CPU perform very different calculations, thus giving the CPU a different test every 3 or 15 minutes.
So, it's not your PSU.
Tell me: who is responsible for teaching you how to use Prime95? I'd like to give them a piece of my mind.
I have had no problems until recently. My CPU overclock is only at 4.2 since at first I thought it might have been that. In the past when I have had system stability problems I would get blue screens, here I get nothing but but a reset as if someone knocked the plug loose. I have rechecked all of my OC settings and voltages are well within safe usage. But I am open to advice in case I have missed something. Right now though the likely problem is a failing PSU I believe.
EDIT: If you would like I can send you or post screenshots of my BIOS settings.

Having no problems until recently doesn't mean it's stable and it's just your PSU. Instability can sometimes take a long time to rear its ugly head. I've seen it many times before on here, and every single time, it's always the same story: the person only ran Prime95 for about 30 minutes. Instability can show up as any problems. BSODs, lock-ups, or just little things that seem like software bugs. Even complete system restarts for no apparent reason can happen. Safe ranges for overclock settings or not, if it's not stable, problems will eventually rise to the surface, especially if they go a long time unchecked like yours.
I say, let Prime95's Blend test run, and don't plan to stop it for at least 6 or 7 hours. If you have an old version that defaults to 15 minutes per FFT, then plan to run it for 24 hours. Actually, before you do that, check to make sure it's not any older than version 27.7. Anything older is absolutely ineffective as a stability test for socket 1155 CPUs.
Yes, still restarts. I thought the same thing at first so I set it back to stock intel settings same effect. I know 850 is excessive for my build but I like to have it incase I want to run SLI at some point and simply so I just don't have to worry about wattage. If you would like I can send you my BIOS settings.
SLI support is only getting worse and worse so you really should drop any and all plans for SLI as the support and the performance is crap and getting worse
I used to have an SLI setup and many of the newer games either have god awful performance or simply dont work and its not getting better its getting worse
Buying a second video card these days is waste of money and you might as well throw money out the window
Buy the bigest most powerful card you can afford and when that is not enough anymore buy a newer video card
That would also allow you to get a smaller PSU since you dont need an 850 watt PSU for a system with a single video card
Edit: as for the Seasonic Focus Plus Gold thats also a very good option and much cheaper then the Prime.
This is what I have been hearing. Honestly unless I come across extra cash I probably wouldn't do SLI. Still an 850 watt eases the mind, even though I realize its overkill for my current build.
A system with a single video card will draw between 200 and 400 watts depending on the config
You dont need 450 watts or more of extra power and a 650 watt could still leave you lots of room
By lots i mean at least 250 watts and maybe as much as 400 watts depending on the config
If you want extra room get a 650 watt or even a 750 watt but 850 watts is what i call the starting point of 3 way GPU setups and you are not even doing 2.
850 is overkill for a single card, i just upgraded to an 850 gold seasonic from a bronze 750 running a 7700k at 5ghz and sli 980 TI hall of fames. Never had an issue, only upgraded for headroom to overclock the cards to the limit. This machine is also on 24/7. Overkill is an understatement.
What i dont get is why people come to OCN to ask for advice and then either partly or completely ignores the advice they have been given
Why bother to ask if you are not going to listen.
I've done what was suggested and even tried again. The problem still persists I don't know what more I can do? Why wouldn't the logical conclusion be to replace the PSU after all other attempts failed? Is it really out of the question the PSU could simply be on its way out? I have been wanting to replace it anyway when I get my new build together since I would rather have brand new PSU than a used 7 year old one. I'm not knocking it at all its been rock solid up until now and yes I know replacing the PSU may not fix te problem which would mean I have a bigger problem.
UPDATE: I installed the Seasonic Focus+ 850 and so far it seems to have fixed the problem. Its no longer resetting at the expected points. Also I believe one of the molex cables had a short. Maybe caused by a failing PSU?
