Quick question on PSU

[steVENOM]

Just a quick question, I was wondering if I may need a higher wattage psu, if someone could just check out my build in my signature and compare it with this screenshot, that would be really helpful. Keep in mind my CPU is clocked up to 5.0GHZ. My GPU is not currently running an oc but I plan to push this 1080ti to the limit for gaming. 

 

Thanks!

An 8700K and 1080 Ti overclocked to the max on air or water might use 500W under load. A 650W PSU is already plenty.

 

A 650W Corsair RMx should fit in your budget just fine if you can afford a 1080 Ti and 8700K.

What is the advantage over my current PSU?

I didn't even see your sig. The CX650M is an OK unit but it isn't as quiet, isn't as well-built (warranties reflect that), and it has a sleeve-bearing fan. Sleeves fail typically in 5 years or so unless the PSU is mounted in some weird way that allows a sleeve-bearing fan to last longer (I.E. how a Corsair 240 requires a PSU to be mounted).

Oh it should be just fine then, its bottom mounted with the exhaust going down and out, I think it should be just fine, it's only 2 years old anyway

I mean, "it should be fine" are some famous last words. That unit only has a three-year warranty because, as far as I can tell, the fan limits the lifespan severely. The components are alright and electrical performance is alright - nothing earth-shattering.

Alright, if I have some extra cash within the next few months I'll consider the RMx, I just wanted to make sure there wasn't any wattage issue or bottleneck. I don't even know what happens if you try to make a pc overclock past its power limit. I would assume just like going past the max clock, it'll just crash and restart safely, so in that case, back to Heaven Benchmark!

The PSU will shut off or restart, yes.

IMO the fan potentially failing in a few years is not really a reason to replace it NOW, unless the noise is bothering you.  Sleeve bearings you will typically hear them wearing out giving you plenty of time to replace once its necessary, rather than wasting money today.

 

Personally I have only had fans fail on PSUs much older than 3 years, the ones that failed early it was always the capacitors.  The thing is, the capacitors will last longer the cooler they are, thus going for a much bigger PSU than you need can potentially extend the life of the PSU.  But if you already have one in good condition, I honestly wouldn't waste the money unless its a model with a reputation to fail badly.

Alright, I'll keep this PSU kicking for a while longer yet, but I'll consider an upgrade sooner rather than later. Thx!

True

False

 

There can be gigantic overbuilt caps in a shitty PSU and terrible caps in an otherwise great PSU (read "Corsair RM fiasco"). 

 

A PSU that can get dissipates heat well makes the caps last longer.

Obviously I'm not suggesting going for a 600W crap PSU over a 400W well built one, I thought that went without saying. (maybe naive of me)

 

I fail to see how my first claim can be true and the second one false though, they are products of the same thing.
