Msi mpg z490 gaming edge wifi

[BNA34]

Hi, I'm having a few issues.  The msi z490 supports 8+4pin for the cpu, however most psus I can find only support 4+4 pins, is that an issue for overclocking to 5ghz?  How does 8 pin (4+4) differ from 8+4 pins?  Is it completely necessary to have 8+4 pins for stability for ocing all cores to 5ghz?

no 

an 8 pin eps can provide up to 384w of power 

it's more than enough

Nope.

Some extra current capability. Usefull for LN2 overclocking on consumer plattforms.

The 10900k can run fine on a single 8-pin overclocked. As it can do 384w.

 

You need to exceed 700w in wattage to find dual EPS on almost all units. 

 

But its really only usefull for HEDT.

If you're on ambient cooling (so air or water cooling), the extra 4-pin can only really be justified if you're running a 10900K, since it pulls a lot of current.

For 5GHz all-core you will likely get away with a single 8-pin with most if not all 10900Ks, though for higher than that plugging the extra 4-pin certainly won't hurt, especially since MSI isn't using the high current variants of their power connectors - again, this applies if you are looking to power a 10900K.

Thanks!  I was looking at a 1000w PSU with 2x ATX 12Vdc (4 + 4 Pin) Connectors.  I'm not sure if that means it only has 8 pins or if that means it has a 4+4 and another 4+4

1000W's quite overkill, unless you're running two GPUs and a 10900K.

And yes, it sounds like that PSU has two 4+4-pin EPS connectors (or two 8-pins basically).

Thank you!  The only reason I thinking about 1000w PSU is because I've calculated my watt use for cpu/gpu/mobo/ram/fans/pump and it's in the range of Obo 650-750w, I'm looking to maybe get a 3070 once that's out which seems like it'll require more juice, honestly I doubt I'll ever actually need that much oomph from the PSU, but it's more a peace of mind.  (I plan to oc cpu to 5ghz, oc gpu, and oc ram)

Just make sure it's a good quality PSU first - that's a lot more important than spare wattage.

 

Normally for pretty much any single-GPU setup a 550W will be more than enough. For a 10900K build though I tend to recommend 650/750W just because of how much current they pull, so say for example if you run an overclocked 10900K and an overclocked 2080Ti, you could actually max out a 550W. But the 10900K is also quite the outlier when it comes to this aspect.

 

If you're referring to the "350W TDP" rumours on Nvidia Ampere, I really wouldn't bet on those a whole lot, if at all. I wouldn't be surprised to see something like that out of AMD, but that sounds way too odd for Nvidia, considering their track record ever since Kepler in 2012/2013 and also considering that they still have a clear power efficiency advantage over AMD, despite being on 12nm (with Turing) compared to 7nm (with Navi/Vega). So basically, I doubt they're gonna pull another GTX 480 on us 10 years later.

That makes a lot of sense.  I think I'll reconsider my PSU choice (maybe a 850watt PSU just to be safe)(I'm looking into corsair gold/platinum/titanium offerings) .  Yes I was referring to the "350W TDP rumour", I'm hoping Nvidia doesn't pull that again, but at the same time, my trust in pc parts manufacturers is quite low.  I've no desire to be in the top 1000 PC's on benchmarking tests, I simply want 5ghz cpu oc for things like rpcs3, where even a 5ghz i9 9900k struggles to push good fps in games like mgs4, and be able to run multiple vms with ease (and some video editing on the side).

Gamers Nexus got the 10900K to pull 316.8W when overclocked to 5.2GHz. At 5.0 all-core, it'll probably be something closer to 200 rather than 300.

If you want to go with an 850W just for peace of mind then sure, it's not gonna hurt, though if it's a lot more expensive than the same model PSU at 750W, I'd really think about it.

 

For a 750W unit (or 850W), some models I'd personally look for would be the RM750i, HX750i from Corsair and the Dark Power Pro 11 750W from be quiet.

The price difference for me is not that much between the 750w and 850w (corsair), I plan to have a good and reliable PSU as I've had PC's short out with a bad cheap PSU before (some no name Alibaba PSU.  Ya, I'm definitely just going with a higher watt PSU for the peace of mind then anything else.  That's pretty interesting!  Unfortunately right now because of the scarcity of 10 Gen Intel right now, there's not much in the way of information in regards to watt draw (hopefully I win the silicon lottery and only need 1.3v - 1.36v to achieve 5ghz oc). 

 

Thanks again
