I am not saying for sure that is the problem. but it wouldn't be the first time a company sends a dud rplacement , sometimes there's a bad batch however theres still other things to check, could be a faulty rail on the power supply for that matter they sometimes will have their regulation go wonky if its slowly dying,. had a power supply fool me into thinking my cmos battery was dead once replaced the battery and the power supply went kapuut a week later. but its just guessing at this point

whats your budget? that will be a factor on the adivce that should be given

to add to this if that's the case which it very well could be there is Im sure an adapter made to resolve this, my experience on the optiplex's 9010 on up i beleive had a strange configuration , and you need an adapter for them but the 24 pins weren't 24 pin on them, knowing dell though they love making stuff proprietary found an article on the subject from the dell community forum https://www.dell.com/community/Inspiron-Desktops/Inspiron-5680-PSU-upgrade-Corsair/td-p/6112154

i dont suggest the void pro ,, my experience with the volume control on mine was scratchy ,,, even with a replacement.

Keep the 4770K it wont bottle neck any budget gpu i know of. if you only have 8gb DDR3, i suggest obtaining a matching extra 8gb kit to go 16gb, GTX 1050 would make your gtx 650 look like a GT210 in comparison ,,, its not the TI but its cheaper. the Ti is a beast of a budget card out performs a GTX770 which was a rebranded GTX 680 so you d definitely feel a huge difference there. a 240gb ssd, crucial or kingston for budget but samsung if you wanna pay a lil extra for better quality.

is this on board graphics or dedicated? could be a ram chip on the card itself has went bad. you ran memtest already so thats been eliminated. my guess is the culprit is within the graphics card or *chip* ,,,

ok heres a crazy idea ,, check and make sure your 4 pin power is seated properly i had this same thing happen to me on a optiplex 990 i upgraded and turns out i had plufgged in the 4 pin power wrong ,,, it did this exact behavior

since you said your gtx960 is working in the z97 system, I dont think its the board, strangely enough its also booting with the power supply you have,and the amd card is working in your system which is also strange, my guess is its just not playing nice with the bios on the z97 motherboard, or the power supply, the load wattage give or take how many hard drives your using or ssds what have you, the power draw should be around 322 watts from the power supply so the power supply should be sufficient enough but it could be defective ,,,, I had one go out and it was messing with everything in the system but would boot up (even wouldn't let the clock hold time (with a new cmos battery ) then it just wouldn't turn on at all , so power supplies can be sneaky about defects . I suggest what another suggested hooking your power supply up to that motherboard see if thats the issue., if its still not doing anything you know its not the power supply. it could've done something goofy in your bios and your bios needs a reset , but I doubt thats the problem,,, worth a shot anyway. to reset it

before you go ripping into the pc it self,,, make sure you have all the right updated proper drivers, i suggest trying to boot into windows in safemode , which only runs the needed drivers to get a gui ,,uninstall all the drivers and start over installing them making sure you have the proper ones, if its not a driver issue , it could be a defective part, and to me it sounds like it could be graphics card, power supply or the ram, out of all these I would hope its the powersupply,,, since thats the cheapest part in this system, also suggest upgrading that anyway, just seems like high mid range system to run on a budget psu.. make sure your ram is seated properly, and in the correct locations as per your motherboard configuration, another thing you can try is resetting your cmos. in otherwords ,, theres too many variables to give you one answer right now.

replacing the power supply is just covering up a underlying issue with your power which could mean ,, somewhere possibly in the breaker box as we call them in the states ,,, where you have a series of circuit breakers if its making the entire house or apartments power going out then you might have a loose ground in your main power outlet circuit breaker or could be a bad circuit breaker for that matter thats become weak , the best bet for you is to resolve the matter by having a electrician come and check things out.

6600K is optimal, 6500 will work just no option for overclocking ,,, thats the main difference between the two besides a stock clock difference. and what card are you getting?

@thony If he keeps the card at stock with factory boost clock and overclocks the processor it should even out Im not saying its gonna be optimal but no way he can afford a 6700K in his budget i just dont see it ,, thing is 1070 will do the job and probably fine, but it will be better with a 1080 even bottlenecked. 6600K falls into his budget thats all (knew what you meant with that typo btw) but if you swap the 1080 for a 1070 lookin at around 150 dollar difference then add a 6700K itll fall into the budget.

You might have problems with games that like more cores but the I3 should get you by on a budget it does have hyperthreading which the virtual cores can be seen to some quad core friendly games as quad. itll certainly perform better and cooler than a AMD counter part. itll probably do just fine for 1080p gaming, I personally am not liking the power supply, but i also have no experience with it. I understand, its a name brand. but most of your (lack of a better term here) gaming power supply brands dont make their Power supplies , they are outsourced and companies like evga just puts their brand on them. if a poor quality power supply goes out itll take your other parts out with it more than likely , just consider that.

no not using the 5.25 inch bays ,,,,The dwarfism is a very good point of course but have a heat dissipation advantage i was considering. but going non overclocked Liquid cooling i suppose i wouldn't have much an issue with heat though plus i want a case that the front fans would be blowing air over the card unobstructed , so I may consider the mid tower instead of course ,, I like the design of Fractal cases until you get to the modular vents on top I prefer the magnetic filter look over that. the coolermaster Pro 5 I also like but I didn't seem as roomy to me as the thermaltake X31 ,, and the X31 (which seems to be a R5 knock off I know ) has that magnetic filter on top , I also like the power supply shroud but this is kinda another topic for a different section of the forums lol
