ba10s118 Posted June 2, 2015 Share Posted June 2, 2015 So I've been using my Akitio thunder2 for a tiny week now, however I've experienced that if I gamed Metro Last Light for more than 2 hours, I usually get a bsod or my pc freezes. I measured the wattage and saw that sometimes it peaked above the rated 18A at 12v. I personally use the KFA2 GTX 970 "mini" OC, which draws a bit more wattage than normal. It seems to be when the GPU maxes out, gets hot, and the fans start hitting max rpm, that it is where the total akitio box exceeds the 18A as provided by the power supply. However this is only shortly, and therefor I do believe that some caps could be the solution. So my "so-far" solution has been: 3x 2200uF/16V caps in parallel with the 12v in. I talked to a electronic guy, and he confirmed that these caps did not have to be charged slowly via a diode. I use yellow XT60 connections for all my stuff, as they are extremely rigid, and are rated for 65 amps. A extreme basic drawing: This could have been done "nicely" with a custom PCB, However I just did a quick and dirty assembling. Remember that the white line on the side indicates a negative polarity. 2 Quote Link to comment Share on other sites More sharing options...
Dschijn Posted June 2, 2015 Share Posted June 2, 2015 Did you still had the overclock you posted in your build guide on the card? +clock +power target? Quote Link to comment Share on other sites More sharing options...
ba10s118 Posted June 2, 2015 Author Share Posted June 2, 2015 Did you still had the overclock you posted in your build guide on the card? +clock +power target?No - I changed it back to stock, to make sure that it was not the OC that interfered with the card - however the events still happened. So far I've not experienced the events. Quote Link to comment Share on other sites More sharing options...
Dschijn Posted June 2, 2015 Share Posted June 2, 2015 Oh, I see. Need to push my setup with long gaming session next month for testing this as well.Good job with the caps! Another approach would be to reduce the power target to avoid load peaks: https://translate.google.de/translate?sl=de&tl=en&js=y&prev=_t&hl=de&ie=UTF-8&u=http%3A%2F%2Fwww.tomshardware.de%2Fhtpc-gtx970-modding-cool-quiet%2Ctestberichte-241708.html&edit-text= Quote Link to comment Share on other sites More sharing options...

However I want to try and make a custom PCB for it, when I get some time. Quote Link to comment Share on other sites More sharing options...
Dschijn Posted June 2, 2015 Share Posted June 2, 2015 Sth I recently read was that the memory OC is more of a power eater than boosting performance. Still... Maxwell GPUs are changing power states very often and can (with higher power targets) have very high wattage peaks. Quote Link to comment Share on other sites More sharing options...
Minz Posted October 21, 2015 Share Posted October 21, 2015 Do you perhaps have an example or just an idea of what a neater/compact version of this would look like?I was trying to imagine a tidy solution where I could hide this in the case. Unfortunately I don't know enough about creating a PCB board and setting this up haha. Quote Link to comment Share on other sites More sharing options...
razvani Posted February 4, 2016 Share Posted February 4, 2016 I'm having a hard time finding the 2200uf 16V in the stores around me. They have 2200uf 25V though. Would these be ok? Quote Link to comment Share on other sites More sharing options...
