Single CPU 8-pin (EPS) for a 5800x in a Gigabyte x570 Master

[KeyperOS]

I am building a new Ryzen 5800x system in a Gigabyte x570 Master (r1.2).
The motherboard has two CPU 8-pin (EPS) power inputs.

 

A colleague is selling my his  (2nd hand) Enermax Maxrevo 1350W Gold Plus (88~93 efficiency) PSU:
https://www.enermax.com/en/products/maxrevo-1350w

 

However it *only* has a single CPU 8-pin connector. I read that the 5800x can draw upwards of 360~380W under full load (and with power draw limits disabled, which this motherboard supports).

 

Will a single 8-pin be sufficient? I read somewhere that it is easier on the VRMs if I were to use two.

Will a dual-molex-to-a-single-EPS connector work as a second EPS?

Am I being paranoid?

 

My 8-year-old Silverstone ST1000-G Evolution (1000W Gold) has two CPU connectors.

 

Please share your thoughts.

Yes. unless you do some crazy LN2 overclock 8-pin is enough

 This is not Intel.

That cpu uses around 110w stock and around 150w when overclocked.

That is not true.

Hmm.... I wonder where you read this information, because this is completely nonsense.

that is more like total system power usage with rtx 3070 or some

Why what? Why 5800x?

 

I can't find the 300W again but I did find this:

you are likely reading total system power consumption. In scenarios outside of LN2 overclocking, it is not gonna draw anywhere near that. 

 

Also a single 8-pin EPS would be fine with that powerdraw.

while its a good PSU, id encourage getting a new good unit instead. idk how much he is asking for that unit.

more than 50% off. 140€.

And I know that he didn't use it very much (but when he did it was in SLI).

A new one at about 800W would be more than 200 (maybe 250 for Gold Platinum).

its fairly old afaik, id honestly spend it on a good 850 multirail unit.

thats not typical eurozone pricing. 

 

Enermax Revolution D.F. 850 W 80+ Gold Certified Fully Modular ATX Power Supply (ERF850EWT) - PCPartPicker

MSI 850 W 80+ Gold Certified Fully Modular ATX Power Supply (MPG A850GF) - PCPartPicker

BitFenix Whisper M 850 W 80+ Gold Certified Fully Modular ATX Power Supply (BP-WG850UMAG-7FM) - PCPartPicker

 

all fairly similar, very good units

I did a VERY quick search, the one I saw was the
Thermaltake Toughpower PF1 ARGB 850W Full Modular 80 Plus Platinum at 267,43 €.

But I agree, if I can find one at a price close to it then that might be better.

 

Thank you very much!

i wouldnt get that one. its worse than the GF1 aswell as the other 3 units i posted. 

 

if you can order from Germany, the Revolution DF is a very tempting offer

[Beerzerker]

If this is the exact one he's got:
According to this it should have a 24 pin ATX,  8 pin AND 8+4 pin CPU power connectors.
NeweggBusiness - Enermax MaxREVO 1350W 80+ Gold Full Modular Power Supply

Check the specs.
Since it's fully modular, if this is indeed the one he has and your friend has this extra CPU power connector that would solve any worrries over it.
Maybe you could find one if he doesn't have or can't find it, should you decide to get it anyway.

It's not a requirement as said with all the above posts but would be nice to have everything it's supposed to have.

I can't find the 300W again but I did find this:

This graph is from guru3d review and it's entire pc power figure. "We show energy consumption based on the entire PC (motherboard / processor / graphics card / memory / SSD). This number depends and will vary per motherboard (added ICs / controllers / wifi / Bluetooth) and PSU (efficiency). Keep in mind that we measure the ENTIRE PC, not just the processor's power consumption. Your average PC can differ from our numbers if you add optical drives, HDDs, soundcards etc. "

Why what?

why x570 aorus master? That is very overkill motherboard. msi b550 A-Pro would suffice. 

or Asus x570-P or tuf too.

If all I wanted was the platform they you might have been right.

But it has the features I want (and more, admittedly they threw the kitchen sink in it) and at 325€ I felt that the price was good as well.

 

I know Linus hates the F-bomb (no, not that!) but yeah, if I can justify it I do prefer Future(gasp!)Proofing features like 2.5G LAN (plus a second 1G), USB 3.2, Wifi 6, the ability to add Thunderbolt 3 etc...

 

Plus, I do like to have the option of eventually upgrading to a 5900x / 5950x once they have eventually fallen in price.
