My spec:
- i7-5820K @ 3.3Ghz
- Asus X99-A Socket 2011-v3 8 Channel Audio ATX (latest bios)
- Corsair Vengeance LPX DDR4 16GB Kit 2666Mhz CL16
- nVidia GTS 450 (does for now)
- ARTIC Blue+ 850W ATX PSU
- Corsair Hydro H75 Liquid Cooler for CPU (underclocked CPU overkill?)
- Corsair Obsidian 550D Silent Mid Tower case (love it)
Almost every-time I switch on, the system power will cut within 5-10 minutes. It'll restart, then sit mostly happy for several hours. I have had it trip again during those seven hours, but rarely, but most frustratingly, as I am usually in a mid-coding session.
I am underclocking the thing just to make sure my PSU isn't sufficient, although considering my GFX card, I thought it would be overkill. Surely my cooling is overkill too. Highest temp I've seen is "VRM" at around 60'. Everything else sits around 30-40 (except for that faulty reading known for motherboard model as reported by Open Hardware Monitor).
Now comes the penny-drop as I write this post, huh I'll keep writing anyway:
I had the same problem with an older rig, the only thing that was the same was the PSU.
I still ask the question, is my PSU at fault, or simply my input power supply. No other PCs, devices have this problem.
Also as a side note; strangely, I get a strange pop sound through speakers every-time a sound is played, as if the sound baord is waking up. I'll leave that for a different post though.
Cheers for any more enlightenment. I love the Tek, and it inspired me to get back into building my own systems.
If your older PC did the same thing and then you built your PC with all New parts the only thing you carried over was the PSU. Now your New PC is doing the same thing. Sounds to me like your PSU is about to fry something. I would bet 100 bucks that its your PSU. Change the PSU and your problem should be fixed.
I'd start with the power supply. I haven't found too many nice things said about that brand. Check out www.jonnyguru.com/ to find something you like, can afford, and is well-reviewed. Personally, I would buy something that is gold rated. You have nice hardware, and the PSU is the last place to skimp. Your total wattage may be a bit high for the system, depending on what you are planning to do with a graphics card. A 500-600 watt PSU will be plenty if you stick with a single GPU setup.
The other option would be to test your input power, like you said. This is a little more specialized, and I don't have much experience in that area. My solution is to buy a UPS that has power cleaning and filtering capability. Maybe someone else can give more advice there.
Also, you mentioned your CPU cooler. I don't think it is a problem. It may be sight overkill, but, in my opinion, the 120mm radiator AIOs are more designed for non-OC and/or low heat processors. I don't think there would be any reason to change it out.
Thanks Guys.
I am probably going for a Corsair HX750i. I like how it is has the ZeroRPM mode (one day we will have 100% silent gaming-performance PCs). I need silence when coding my games, and then instant power when testing.
Its probably more than I need, but I am planning to upgrade my GFX card in the next few months so that I can leverage coding in 4k. Two 4k screens would be perfect, which would require 2 decent cards;- maybe one day.
Bit gutted that I chose ARTIC Blue+ now, even though The Tek always banged on for a single rail PSU.. That'll teach me! Well its going to be lobbed back to the supplier now.
Going with a higher wattage than you need will let you leverage the Zero RPM fan mode for a wider power consumption margin. This sounds like a good application for that method!
Good luck with your upgrade plans!
