I like having headroom. Never know what I end up doing down the road.

Long story short,

I just switched to x299.

Everything was working well then yesterday I start getting crashes while idle.

Thought my voltage was dropping too low while idle so I messed with my oc some. That didn't work.

Ended up testing full stock and still got crashes while doing basic tasks or stress testing.

Switched out my x850 for a cx500m I have and my problem seems resolved. Was able to pull over an hour stress test where before I'd crash within 20 min of starting a stress test, total system outage.

I just started up the rma process on the x850. Thinking I'm going to save the money on a new unit and instead get this one replaced/fixed.

Well i don't really see a reason to buy a power supply based on efficiency. I think its a waste of money. I think the prime gold is going to be just as good as the titanium. And price wise the prime gold is about $20 more then the KM3 you have currently. But you also get a 12 year warranty compared to the KM3's 7 year.

Maybe you can get them to replace the KM3 with the Prime Gold?
:D

Ok, if it absolutely has to be an 850W PSU, then here's one you could get for far less than $200:

https://pcpartpicker.com/product/jWFXsY/seasonic-focus-plus-gold-850w-80-gold-certified-fully-modular-atx-power-supply-ssr-850fx

I sorted by 850W PSUs and higher, and I sorted by the lowest price first. Guess what: that's the very first 850W PSU that I can confidently recommend. What a coincidence that it's the Gold version. Don't tell me that 80+ Gold PSUs are are inferior to 80+ Titanium or Platinum: it's just a difference in efficiency. It's not lower in quality. The quality of a PSU can't be judged by which 80+ Certification it received. Their testing methods don't include checking to see if the PSU is any good. They just check to see what its efficiency is and then they move on to the next PSU.

However, as I said, you could spend less than half of $200 and still get far more than you need: https://pcpartpicker.com/product/Rp8H99/corsair-power-supply-cp9020091na It's $70 and it's extremely high-end.

Here's a very solid 750W PSU for $82.99: https://pcpartpicker.com/product/VwR48d/seasonic-power-supply-ssr750rm

There are plenty of others I could recommend between $82.99 and $109.99 but they are all 650W and 750W PSUs and the 850W PRIME Gold is $109.99. So at above $82.99, the next wisest purchase is the 850W PRIME Gold.

Hey thanks for the list.

I'm going to go through with the rma process. Forgot that my psu had a 7 year warranty. Also this cx500m seems to be holding up well so I'm not in a huge rush to get the psu replaced asap.

They look nice but they are a freaking nightmare to hide and route behind the motherboard tray and they take up a ton of space compared to the stock cables
Unless you buy a bunch of cable combs for them dont bother as they look worse without combs as well as takes up more space

Individually sleeved cables is an idea that might be good theory but is a pain in the butt in the real world
I have had a few sets of individually sleeved cables and i have come to utterly hate using them because of how much space time and effort they take.

Ah thanks.

Part of my reason for wanting them was they looked like they'd be easier to work with. If they're worse then I'll stick to the stock cables.

That's kind of what I thought. Sleeved cables look like they'd be easier to manipulate.

The stock G2 cables might be a bit stiff like you said but i rather have one big stiff cable instead of 6 8 or 24 freaking wires going all over the place and criss crossing over each 117 times
If you want individually sleeved cables buy a bucket load of cable combs for them or duct table those bastard wires together behind the motherboard tray so they dont go all over the place

Like i said it takes a ton of time and work to get them to look even decent and i feel like all the time and work is not worth it at all.

I've got 100's of black zip-ties that I don't mind using. I buy them in bulk.

Yeah I don't know. It's an idea. My 24-pin connector is really stiff at the psu and it pulls itself loose over time. I think this could be causing my psu issues. When you send in a psu they don't want you to send in the wires so I think I might buy buy a new 24-pin cable instead of trying to get them to replace the one I have.

I used sleeved extension cables because they were cheaper then buying cable sets. Only issue is you need a little bit more room behind your motherboard tray with extensions. However having longer cables made it easier and nicer to route.

Since I already have the psu and wires out of my system now would be a good time to move to sleeved cables.
I regret to say that I don't know enough about sleeved cables to have any opinion. Personally, I only look at the interior of my computer when I clean it, so I don't care about its appearance. So, that's really why I haven't learned anything about sleeved cables (or sleeving cables manually).

Shoot. The more I think about it the less I feel like waiting for this psu to rma for the next week or two. If I order a psu through amazon today it will be here Monday.

I know I don't need it, but, I'm still leaning towards one of the "Seasonic TITANIUM" psu's. I mean, a few hundred is a drop in the bucket compared to the rest of my rig. Though I am thinking I might go with the 750w over the 850w since I top out around 470w of power usage under current settings. A 750w psu would still offer me a lot of headroom.

I still have 10 hours to order and get the psu on Monday. I'll let it sit awhile longer and see how I'm feeling tonight though I'm leaning towards getting a new psu. I can still rma the x850 and keep it around for another build or back up.

The Prime titanium commands a huge price premium making it somewhat overpriced
A better option is the platinum or gold rated versions.

I just want to get the best. The only reason I wouldn't want it is if there's a reason that it's not as good as it should be. Like a cheaper unit has better quality components. As long as it's top dog for its price I don't mind buying it.

But being Titanium certified doesn't make it higher in quality, just like I said last night. You would simply be paying more for higher efficiency. Even the PSUs under $100 that I showed you are the best of the best, unless otherwise stated.

What will you be using your computer for? Gaming and overclocking? I mean, unless you are gearing up for a very serious professional world championship overclocking competition, you really have no good reason to spend that kind of money on a PSU unless you have a very high income. Even then, some of those PSUs I showed you that are under $100 would do well for such a thing.

I have to go though. I'll be gone for about the next 10 hours or so.

It is what it is. I've got a $600 cpu, $720 gpu, I'm about to drop around $500 on some ram. I can afford to buy a $200 psu. There's no reason for me not to. I hate saying it like cause I don't want to sound like an arrogant A-hole but I mean, there's no reason for me not to buy the Titanium if I do buy a new psu.

Being able to afford it doesn't mean you should spend it. If you really want to spend $200, spend ~$100 (or even less) on the PSU and then put the rest toward something else.

I have to be honest: even if I had tons of money to throw around, I wouldn't spend it like this. Some day when you're on social security you'll wonder why you didn't try to let your money pile up. There's nothing about the Titanium that's any better for you than the other PSUs I showed you, even the RM650x for $70.

But really, I gotta go or I'm going to be very late. Sorry man. I'll reply when I get back tonight.

You get around 22mv of ripple and 0,33% average voltage regulation with a Seasonic Focus Plus
It has better voltage regulation then the Corsair RMx and the EVGA SuperNova G2

It has better voltage regulation then almost anything else maybe other then the Prime series
Ripple while not as good as the G2 and RMx is still very very good

All in all the Seasonic Focus Plus offer much better bang for buck and value then the Prime does

You dont buy a million dollar super car to drive half a block down the road to buy your shopping
The Seasonic Prime is like a million dollar super car.

This ^

I was actually thinking Hypercar but coolermaster made that.
