PC won't boot

Ok but then why is it that using the FX-8320 in the NAS works fine but then the FX-8320 with the NAS PSU in my board doesn't? What's different. Same CPU, same PSU, just a different mobo. I could understand the NAS PSU with my FX-9590 causing problems but that PSU doesn't even physically have enough connectors to power the 9590.

Then that's a shitty old power supply and it's just luck that it even works on the NAS. It's probably hanging on by a thread. I wouldn't be surprised if it shit the bed soon.

When I mean it doesn't physically have enough connectors I mean it has one 8 pin for the CPU but the 9590 requires 4+8 pin. It's plenty for the NAS and it's not that old.

Dude. It's the power supply. 100%. Get a new, current technology power supply and your problems go away. It's easy to test and doesn't cost anything to buy something and return it if it doesn't - except for the time and gas to get there.

And since you haven't mentioned the brand and model of the power supply in this thread, my suspicion is that it's some shitty brand.

My PSU is a Rosewill 1000W Bronze Series PSU.

LOL ding ding ding

Is rosewill bad? I mean I know corsair is like the best there is but is it really unreputable?

It ain't good. It's better than some no name chinese shit, but not by much.
Don't skimp on the power supply.

I will only use Antec and Corsair. I bought an EVGA and it failed 3 weeks in, and the replacement worked for about an hour. And Antec seems to be on the decline - product wise at least. However I've had many of their power supplies and they were all great.

Alright well I've already RMAed the board again since they're paying for shipping both ways this time I figured I've got nothing to lose. If it comes back and still doesn't work right and they say it was all good then I'll really start looking into the power supply but I thought after the tests I did with the unit in my NAS that I could pretty safely rule it out.

Jesus. You RMA'd an Asus board but kept the potato tier Rosewill power supply.
Fucking noobs.

...I mean given that I've already had one Asus board die on me in the last 2 years and the board I currently have is an RMA unit I have my doubts on Asus' build quality. I wanted it to be the PSU. In fact when I got the board back and it still failed I thought for sure that's what it was. I probed the 12V, 5V, and 3.3V rails with a multimeter during boot, I tried a different PSU that I know works just fine and nothing showed any signs that it was the PSU.

The thing is that it's so much easier to try a new power supply than to disassemble the whole computer to send back the motherboard. And you have doubts about Asus motherboards but no doubts about a Rosewill power supply? Come on. There is a reason that Rosewill shit is so cheap. Asus is widely regarded as the best motherboard manufacturer. Is Rosewill the best PSU company? NOT EVEN CLOSE.

PSU problems are a real frustrating problem. Everything quits working. And you feel like it could be anything. But when all you have to do is unplug the power connectors and plug in a different one - not even disassemble anything - you should test that. And when you have an old power supply that doesn't even have the contemporary connectors on it, you were being irrational.

That PSU that I tested is only a year old. I bought it when I built the system one year ago and it has dual 6+2 pin PCI-E power and 4+4 pin CPU power. All it was missing was a second 4+4 pin CPU connector or a standalone 4 pin CPU connector which I would assume that's simply because it's a 550W PSU. At that wattage a single 4 pin or a single 8 pin is probably expected. A 4+8 pin config, as is required for the 9590, and they probably expect you to buy a higher wattage PSU. That's why I tested the 550W PSU with the 8320 from the NAS but the issue still persisted which is why I'm convinced it isn't the PSU. We'll see...in a 1-2 weeks I'll update this thread after I get my board back and see if it was the PSU or not. My bet is it's not but I might be eating those words later. If it is I'll be getting a corsair HX1000i instead.

That's a nice power supply.. but 1000w?

I'm 2x Xeon 2699v4's with 128GB RAM, 7 drives, a GTX960 4GB, and only have a Corsair RM850.
UPS tells me that I draw 160-250w on average. Max, everything at top rated power is only about 650w.

I have an FX-9590 and an R9 Fury. I've seen my system pull 700-750W with CPU and GPU at 100% so maybe 1000W is a bit overkill. While gaming I hit like 450W and at idle I pull about 200.

I just looked. $150-$190 for a HX1000i. Not as bad as I thought it would be.
I guess if you already have costs sunk in team red, might as well go for it.

I like AMD. I know they're not the best in terms of CPU or GPU they're good enough for what I need to do and as long as they can do what I need them to do I don't mind giving them my money to try and help them make a comeback.

I had a PhenomII x6 (1055T) that I liked a lot and ran for several years. But I think that was their best processor line. And that was a long time ago. I stayed with AMD for a long time, but I had to upgrade. It's now been 2 cycles of upgrades for me. I hope Zen comes back nicely, but since I just sunk $3k in my current system, I doubt I'm changing any time soon.

Yeah...even if zen does come back swinging I'm not sure I'll upgrade. Maybe but for right now my current system is fine...provided I can get it working again :/.

Plug the pump into a CASE FAN or other non regulated fan header, only the fans should be on CPU_FAN or CPU_OPT. Right now your pump is ramping up and down depending on CPU temp instead of just being on.

Don't know how you haven't had problems prior to this recent stuff. When you start cold there's probably little power going to the CPU_FAN header because - cold, this might not be enough to get the pump spinning properly which feeds back to the BIOS as a low or no RPM fan.

Won't cost you anything to move those around and try it.
