Seasonic PRIME 1200W Platinum

i wouldn't do that

@LukeSavenije Please suggest an alternative. Needs to have the same or higher wattage  

@_StrikE_ the problem with prime is that it's single rail, unlike most units at that price, which have 4 12v rails

on 4 rails the ocp would trigger at around 30 percent, whereas a single rail would trigger around 120 percent.

and seasonic has more mistakes than you think

s12ii/m12ii (until 620w): old, outdated platform with group regulation, no undervoltage protection

focus: problems with certain GPUs or high ripple (about double atx spec in some testing at 130% opp), single rail (only exception is the nzxt e so far, which only has the single rail part)

s12iii: double mag amp, while similar units have dc-dc regulation

prime: loud at higher loads, cheap fan for it's level, no multirail option

I'm actually soon to have something back from seasonics r&d about the single rail part on prime (in this case the new prime titanium 1600w)

@TopHatProductions115 but yeah... name your preferences anf budget, I'll take a look for something

@LukeSavenije What is the cheapest PSU that can reliably run the ADM Threadripper build (listed above) 24/7?

this antec (actually one of my favorite oems who made it, delta): https://pcpartpicker.com/product/n3rG3C/antec-power-supply-hcp1300platinum

this corsair (made by good ol CWT, custom design) https://pcpartpicker.com/product/f7L7YJ/corsair-hx-platinum-1200w-80-platinum-certified-fully-modular-atx-power-supply-cp-9020140-na

this corsair (which is my other favorite oem flextronics if i see it right): https://pcpartpicker.com/product/nhHRsY/corsair-ax-1000-w-80-titanium-certified-fully-modular-atx-power-supply-cp-9020152-na

the NEW v-series (which is also a delta, i think similar to the antec in platform: https://pcpartpicker.com/product/Ywx2FT/cooler-master-v-platinum-1000-w-80-platinum-certified-fully-modular-atx-power-supply-mpz-a001-afbapv-us?history_days=730

the ax1200i, which i can varify is flextronics: https://pcpartpicker.com/product/vkYXsY/corsair-power-supply-ax1200i

the dark power pro (a custom design made by fsp): https://pcpartpicker.com/product/mgwqqs/be-quiet-power-supply-bn255

and i might have missed a couple, but the other ones i could find were single rail

and before i forget it, i'd swap to the meg on x399, they have the best vrms for threadripper

@LukeSavenije I have to say, I like the look of the MEG. However, the PCI-e slot placement is a bit of a challenge to get around without slapping riser cables on it (esp. in comparison to the mobo listed originally). With the ROG board, I could use a PCI-e splitter on either the top or the bottom slot, to accommodate for my sound card and capture card (still leaving out a few things - WLAN), and use the other three x16 slots for GPUs (since the slots are spaced nicely). With the MEG, I'd possibly have to rely on the on-board audio, and hope that it can handle my audio equipment without external amps (since I don't have space for those - anywhere). Still not sure about where I'd plug in everything else. The slot placement is a pain  Aside from that, I'll look at the PSUs you've posted  

hm... bummer

the meg has 70a powerstages... that's why really. but the zenith is also really good. 

it's whichever you like really, and if you find something interesting i didn't mention in mine, you can always ask me about it

@LukeSavenije I'll see if I can make the MEG work. For now, though, not making any promises. Hypothetically, I could:

• use PCI-e x16, slot 0 for a GPU
• use PCI-e x16, slot 1 with a splitter, and hope there's enough room between slots 0 and 2
• use PCI-e x16, slot 2 for another GPU
• use PCI-e x16, slot 3 for another GPU

With the ROG, I was gonna do something like either:

• use PCI-e x16, slot 0 for a GPU
• use PCI-e x16, slot 1 for another GPU
• use PCI-e x16, slot 2 for another GPU
• use PCI-e x16, slot 3 with a splitter for the audio and capture card(s)

or 

• use PCI-e x16, slot 0 with a splitter for the audio and capture card(s)
• use PCI-e x16, slot 1 for a GPU
• use PCI-e x16, slot 2 for another GPU
• use PCI-e x16, slot 3 for another GPU

and since there tends to be enough space for smaller devices near the top and bottom, that would have been easy to setup. Not exactly up for taking a jump and hoping there's enough space later. Does anyone on the forum own the MEG, for measurements?

@LukeSavenije The Corsair AX1200i 1200W 80+ Platinum ATX PSU looks nice. @Skanky Sylveon, what do you think?

the new axi's are multirail (cofigurable) flextronics PSUs

i approve

Okay - Plan 3 needs some changes (especially seeing that the Proliant can only take 2.5-inch drives). Still looking into whether the GPUs are compatible with the GX Blades, though:

• https://forum.level1techs.com/t/assistance-with-device-slot-compatibility/144261

May actually have to scrap plan 3 altogether, seeing that no OEMs appear to provide support for normal PCI-e x16 expansion cards. This is getting to be annoying...
