Mmm....electronics torturing at its best! This little beast is awesome. It's nice to see EVGA stepping up and producing such a cool niche product and actually bringing it to production.

Long-time awaited moment, thing that noone does before.
All-mighty EVGA's "The Untouchables" EPOWER available.
http://www.evga.com/products/moreInfo.asp?pn=100-UT-0400-BR&family=Accessories - Hardware&sw=4
EPOWER card is designed to operate with two voltage outputs :
- VCORE output– Voltage adjustment range of 800mV to 2000mV. Current source up to 400 A.
- VDIMM output – Voltage adjustment range of 1000mV to 5000mV. Current source up to 80 A.
Minimum requirements
Minimum 600W (42A on +12V rail) power supply with two or three 6-pin PCI-Express supplementary power connector cable for each EPOWER card used in system.
This device is intended only for advanced user use with basic electronics experience. EPOWER is covered only by DOA warranty
Basic usage guide:
1. Disconnect stock VRM power inductor on desired channel
2. Open copper plane for ground and power on target device
3. Solder thick (AWG10-AWG12) wires from EPOWER GND to ground and VCORE or VDIMM points to power.
4. Default startup voltage on VCORE – 1200mV, VDIMM – 1500mV. Maximum current for VCORE – 400A, VDIMM 80A.
5. Good rule to follow – one pair of wires (VCORE+GND) per each 10-15A. For simple VGA like with 2-3 phase VRM best to use 4-8 wire pairs. For high-end VGA should be no less than 10-15 wire pairs. Top GPUs like GF100, GF110 must use as many pairs as possible physically.
6. Multiple wires reduce voltage drop under idle and load states. If drop (difference of voltage between EPOWER card and GPU capacitor voltage near package) is more than 100mV – more wires are needed to compensate.
7. EPOWER card requires forced airflow under heavy load conditions. User can use onboard 3-pin FAN connector.
8. After connecting EPOWER to GPU always check resistance between power and GND to ensure no shorts. Normal resistance range for GPU is 0.5-10 ohm, for memory – 5-200 ohm.
9. For videocards with advanced PWMs (>3 phase) check VR_ENABLE signals and VR_PGOOD (power good).
10. Connect PCI-Express power to EPOWER card AND videocard. If you don’t use secondary power on EPOWER (3phase) you can leave “INPUT DIMM” connector not connected.
11. If after power on voltage is OK, but system does not detect videocard – cut VR_PGOOD trace near onboard PWM on videocard. This will prevent onboard VRM to reset GPU (because onboard power is not used – it’s fault state for it)
12. For voltage adjustment on EPOWER use EVGA EVBOT with X58 motherboard firmware. VCORE voltage is CPU Voltage, VDIMM is Memory voltage on EVBOT.

Retail price is $99.99 USD for this power monster. Shipping price not included.
Refer to EVGA's page linked above for ordering.
Some people already tried this unit during their OC sessions and had lots of fun.
