EVGA SuperNOVA NEX1500 Classified Power Supply + 4-way EVGA GeForce GTX 680 Classified on 240VAC
The project is complete. 🙂
Step 1 was to acquire an EVGA SuperNOVA NEX1500 Classified Power Supply. It replaced my Seasonic X-1250 – a great PSU but I decided to upgrade for several reasons: warranty (10 year warranty from EVGA), sleeved cables, EVGA’s SuperNOVA monitoring software, and up to 1650W of power potential (plan is to do water cooling sometime soon).

EVGA SuperNOVA NEX1500 Classified Power Supply versus the Seasonic X-1250 Power Supply – size comparison.
Step 2 was to get a new 240VAC power outlet run to my computer – my buddy Jason from AMP took care of that! This allows me to run the NEX1500 in “OC Mode” which is 1650W.
Step 3 was to install the NEX1500. This went without incident until I tried to power up – there was an issue with the EATX12V CPU power connectors on the ASUS Rampage IV Extreme with the power cables provided by EVGA. Basically, I needed to buy an 8-pin to 4-pin + 4-pin splitter to make it work. More details on the EVGA forums at this link.
The final product – so far, so good. Not running in “OC Mode” (1650W) yet, because I don’t need it. But it’s an extra gear that will be there should I need to turn it on. For those that are curious, I’m running in single rail mode because EVGA recommends that if you are running SLI.

Hi sir;
Who better to ask than you?! Are the microstuttering issues that happened not only with GTX 680s in sli, but GTX 680s in general (well, it happened to some people at least!)fixed, and more importantly have you experienced any in any of your games? Let me know if you wish, and VERY nice PC, am so jealous!

Hi, I have not experienced any micro-stuttering. I currently have a 4-way, 2-way, and single card rig.
