EVGA launches EPower VRM board

EVGA launches EPower VRM board

EVGA's EPower Board offers replacement VRMs for those who don't mind a bit of hair-raising soldering.

EVGA has announced a product that should get the hardcore overclockers salivating: an add-on voltage regulation (VRM) board for motherboards and graphics cards.

Dubbed the EVGA EPower Board, the add-in VRM board is designed to replace stock voltage regulation modules on high-power devices in order to allow for even more power to be shoved through; a critical part of extreme overclocking.

According to EVGA's figures, the EPower board can run at a VCORE adjustment range of 800mV to 2000mV at a current of up to 400A, or a VDIMM adjustment range of 1000mV to 5000mV at up to 80A. To put those figures into context: EVGA recommends a 600W power supply with 42A on the 12V rail per EPower board used in the system.

Before you get excited about the potential of the board, there's a catch: the system is hardly plug-and-play. Those who have bought the board are expected to solder it directly to the motherboard or graphics card of their choice, replacing the existing VRMs with a connection to the EPower board. With the installation instructions (PDF) advising users to cut PCB traces to disable on-board regulator modules, it's a hair-raising - and warranty-trashing - experience.

The board itself gets a little warm, too: despite a hefty heatsink, EVGA recommends the use of forced air cooling via an 80mm or 120mm fan as a minimum and warns that those using extreme cooling systems like liquid nitrogen should position the EPower board well away from any possible condensation points unless they want to see the world's most expensive indoor firework display.

Thus far, EVGA hasn't confirmed UK pricing, but the EPower board is available in the US priced at $99.99. The first early revision boards were shipped to customers late last year, with some eyebrow-raising results.

Do you think the EPower board could be a worthy addition to an overclocker's arsenal, or is EVGA just showing off? Share your thoughts over in the forums.

Yeah....I think I'll let electronics engineers at the graphics card manufacturers do the task of selecting and implementing ideal VRMs for their cards, thank you.

Then this product is not for you!

I looks interesting and I would love to see someone from here use it!

Interesting, just taking the same idea people used when they cut of 480 power circuitry, and soldered that on to provide better power.

And Longweight, has already been done ;)

You can see how long it's been in development, and an example of him doing the same thing just with another card, rather than a purpose built device.

Ugh, double post.

Looks like it could be a good Idea if you were into the hardcore side of overclocking with more exotic cooling but i'm not sure i'd use it on my home pc.

Looking at some of the soldering that those guys in the link have done really makes me cringe.

Very interesting. I suggested something akin to this as part of my entry for last years competition run by Asus - Modular VRM's.

Now, if eVGA could make this a truly modular design without any soldering required, then imagine how motherboard design could be taken. First the VRM's, then the CPU socket and RAM sockets all on daughterboards. It'd be like 1989 again, but this time with enthusiast class kit allowing us to seriously customise kit to suit.

I know it eeks of diversity which adds cost, but done right I think this is the nugget of a genius idea. After all, i had the same one :) ...sort of

If I could use Liquid Nitrogen without being moaned at I would use this if it meant I could really push my hardware to it's limit's and beyond for some suicide run's.

I would love this sort of thing to be able to be bought and slotted on to the board's meaning we could choose what we run on the board's in term's of VRM's etc.

What is really cool is that if this tech takes off to daughter boards it can really open up a new age of durability as well. Motherboards are getting very expensive for the high range and this tech would let you replace just the daughter board in the event of a vrm failure instead of the entire board. This could also make things faster and easier for servers! Time to replace daughter board < time to replace motherboard.

File this under Ultraextremecoollollercoaster or whatever it is BT refer to it now as.

Top notch idea for some serious extreme overclocking :D
