Description
*This is not a complete card, this is a modification service.*
We have been hard at work unlocking the potential of workstation graphics cards, and the A4000 is the one we found the most potential in.
Our power mod not only increases base performance of the A4000 by roughly 14%, but unlocks the ability to overclock the card to performance levels rivaling an RTX 3070ti equaling a roughly 36% performance increase. Final overclocking results will vary with silicon lottery of course. Here is the world record time spy score we achieved with a test card we have here modified exactly like we supply to you: 3dMark Time Spy Graphics score of 14229
In addition to the performance gains, we have designed custom brackets to properly retrofit a PNY 3060 ITX cooler onto the A4000 allowing this beast of a card to fit into many SFF builds.
Our customized shunt resistors are balanced in a way that is designed to never overload the PCIE x16 slot. We also replace the standard 6 pin power connector with an 8 Pin external power header to provide supplementary power. Total board power with the mod peaks around 205w, measured power draw will need to be multiplied by approximately 1.82x
Turn around time for modification can take up to two weeks from when the card arrives at our facility, but we have been able to keep up fairly well so expect something closer to 3-5 business days.
The Power mod and cooler includes installation of:
Custom balanced shunt resistors
Custom brackets to ensure proper pressure on VRM thermal pads and provide mounting for the PCIE bracket
PNY 3060 ITX cooler and fan
8 pin PCIE power header
Dimensions after the modifications are complete. These are the extreme extents of the largest part of the card in each dimension:
Height from PCIE slot PCB Edge to top extent of the fan shroud: 4.885″
Length from mounting bracket to rear of fan shroud: 6.622″
Thickness including mounting screws (total thickness): 1.587″
Thickness as measured from rear of PCB to front surface of the fan shroud: 1.434″
If you would like to supply your own cooler, select the “I’ll provide the cooler” option. Please ensure the cooler supplied is the correct cooler pictured below, there are a couple versions out there and only this one has cold plates in the correct places. Providing the wrong cooler will result in a delay of your order and an additional service charge.

For the price this is unbelievable considering the uplift you get not only in performance, but also longevity. Temperatures are never out of control even when overclocked which makes me question what Nvidia was doing when they were designing the card. It only took about a week from shipping my card out to getting it back, but most of that time was spent in transit. My card appeared to have only been there for less than a day. In my opinion this mod is essential to anyone who owns an A4000 period.
