There's a heatsink over the high side but you can see the low side FETs in the photo. Maybe with a higher-res photo we could make out the part numbers for those.

I dont see any other mosfets and such high end VRM will almost certainly have integrated powerstages

What's under the heatsink and thermal pad then?

Integrated powerstage

Thats a component that includes driver, highside mosfet and lowside mosfet in one case

[Max_Settings]

Where do you mount it though?

Solder it on or connect with wires (the jankier way)

They're both pretty janky

What do you reckon are the chips on the other side of the inductors then?

Most likely capacitors

Soldering it is the intended way tho. Fat-ass short wires straight into the power input of the GPU is exactly how you should use it.

 That's like, more than 1100W that this VRM can handle, according to EVGA. Hot damn!

Until it can supply the Flux Capacitor with 1.21 GiggaWatts I shall not purchase.

 

On topic:

This could lead to impressive overclocks for Pascal, a similar design allowed Maxwell based cards to almost reach 2000Mhz on LN2/Helium. Given that Pascal can reach those frequencies on air I wonder what the limit is for Pascal.

forgot LN2

Yeah. Raspberry Pi works too I think. 

 

Or just use this for EVBOT lol. 

 

Wouldn't mind getting one to experiment on a 660 I have laying around with. Would seem like a waste though. 

Gimme dat

 

You can reuse an EPOWER on a bunch of cards for benching. You'd at least want to be using chilled water or phase change on cards to buy this unless baller.

They'll need LN2 for that though for sure.

 

i'm interested in the overclocking in more power hungry cards on this thing - like Vega

Kepler cards can overclock quite a bit if you push voltage through 'em IIRc

Eh. Reference PCB might explode since it's cooled by a blower. Things got hot at 1.3V. 

 

This + waterblock would be overkill but might let it go fast. Ultimate goal would be LN2 tho. Even if it's a 660 it's fun to experiment.

Pascal in LN2 is hitting around 2.3GHz lows and 2.6GHz highs for 3D bench.

 

GPUPI is around 2.8GHz highs. But then again it's not 3D. So higher clocks are easier. Even normal cards can hit high clocks in it with non-extreme cooling solutions.

 

Fastest benched Maxwell card was one of the 980 Classifieds pulling 2.3GHz. Although that was with it's own Classified VRM. Classified VRM = EPOWER basically. I wouldn't be surprised if this card is just the 1080Ti KPE VRM now on one easy little card.

How much is that shipping from UK to US(?) tho. 

 

Chilled is next goal with PC cooling. Could *probably* daily it.

Buildzoid did OC the 1070 to such a high level it was basically matching decently overclocked 1080's and an epower is actually not required, a bunch of caps were enough actually.

 

And yes Ln2 would be required to utilize something like the epower properly.

 

In case you are wondering how a card would look like with an epower, it's something like this:
 

 @dave_k buildzoid did kill is FE but he has an RX vega 64 so it's not exactly an issue it died

Ugh, that sucks. What's the point of sponsoring someone like buildzoid when he can't do something like that? D:

He did actually softcore undervolting video XDDDDDDDDDDDDDDDDD

Yeah because people asked and it's nice that he did that but seriously, pushing hardware to the limit is what he loves to do and with no hardmods that's really hard to do.

EVGA has introduced a standalone VRM power board for your graphic cards and motherboards. The board contains 12+2 phase and threee 6-pin pcie power connectors. Also has built in EVGA's EVBot MKII, for instant change voltage control.
 

Can orders yours today for a low price of just $249 dollars.

FINALLY EVGA launches a product that wont be price jacked by miners!!!

Not sure maybe £20 for a very small package?

 

If you can find a used phase change you'd be set. They double as chillers using a spare CPU block attached in the loop besides doing -45 on a single processor.

 

Any cooler you plug in the wall will raise your electric bill a fair bit.

Sadly buildzoid is not with us to see that.

If his Vega FE would've been alive, he would most likely buy that.

I would buy that to fix my Strix B350-F's VRMs lol

he would not buy this to use in the vega cards, their vrm is way too good

[Coaxialgamer]

I'm happy to see evga is releasing enthusiast stuff like this. Most of their recent stuff has been good, but it never felt like it pushed the limits. The Epower lines and the SR2 board are such products, however 

[CommandMan7]

620 Amps @ 1.85 volts = 1147 watts of power. Damn.

For reference, a 9590 will do nearly 370 watts, and an overclocked 295x2 will draw 740 watts, which is 1,110 watts total.

[FloRolf]

I remember when last year or whatever, the took these things and added them to a R7 240 or some low-end card to OC the living crap out of it, lol

 

Edit:

[minibois]

Might be helpful for my colleague's build, which has 970 motherboard that can't keep a good temp on its VRMs due to the CPU installed

/s

 

I love seeing this really enthusiast PC stuff. So niche.
