fix PSU overheating?

[Ihaveswag]

Hey guys,

is there any way how Ican fix my PSU overheating issue?

So I know that it is the PSU overheating, because whenever I played demanding games in summer and had 26-27,5°C room temperature it happened several times a day that my screen goes off and the sounds glitches and a few seconds l8er the pc shuts down, while since it was colder (last 7 weeks)and my room temprature never exceeded 23°C, I haven't gotten any crashes whatsoever. I can also back this up, because whenever that happened and I went into the event log, I had the ,,Kernel Power'' thingy there, which indicates that there was something wrong concerning the power delivery. 

I also had a Corsair CX600 in the first 3 weeks, where there were no problems, but the reason why I replaced it was,that after one week the fan would just rattle insanely loud and then it didnt spin at all, so the PSU overheats when I fire up a game and crashes afterwards. My dad was kind enough to buy me a new PSU from a brand that I trust (Silverstone ST75F-GS 750W 80+Gold), since my brother has been using one of that company for 5 years in his gaming rig.

 

I dont think that this has much to do with it, but I have the PSU mounted in a way, where the fan isnt on the bottom where a small vent is, but its facing upwards, but I can't imagine that the PSU can't handle this, since many cases dont have any PSU vents and I have a good fan setup. My bros rig uses more power than mine and has one 80mm case fan and a 500W bronze Silverstone PSU and he never had crashes with it.

 

So guys, what do you have to say about this or do you have any helpful ideas? When I ran into this issue in summer, I was actually thinking about getting a XBOX ONE cuz I was so angry about that PSU issues

 

My specs:

i5 4690k 4,2 Ghz @ stock Voltage 1,079 stable, max temp under 1 hour prime95 69°C

EVGA geforce gtx 970 SC stock with stock fan curve 75°C

Kingston HyperX 4x4GB DDR3 1600mhz CL9

Gigabyte Gaming 3 Z97X

Crucial m550 250GB

WD Blue 1TB

NZXT S340: 120mm intake front, 120mm blowing out at the back, Corsair AF140 LED blowing out on top

 

PS: the EPS CPU motherboard cable of the PSU is too short for connecting it when I have the PSU mounted with the fan downwards

How do you have the PSU mounted in your case

 

Flip it and see what happens.

Heh? How? Pictures?

 

Also, nearly every case I've seen has PSU ventilation. Even ITX cases.

because  when I built the PC i wanted to have the fan face in the downwards direction, but it turned out that I need another 2cm or so to just connect to the mobo

Well shit, I don't know what to tell you then.

 

Like, the issue could be the GPU is outputting so much heat that it's getting into the PSU - assuming you have the ACX version and not the reference design 970.

Well there's your problem. You didn't think about this beforehand? You need to either do better cable management or buy longer cables.

 

I'm very skeptic that those cables aren't long enough because that case isn't very large.

EDIT: I read wrong. OP could buy a set of small extensions or route cables better.
