Dumb and Dumber 3

[suityou01]

I built a new system (haven't spec'd and built one in about 20 years).

AMD FX 9590
32GB Ram
Sabretooth FX990 R2.0 Mobo.
500W PSU
Zalman CSP990 MAX (CPU Cooler).

I installed Centos7, and then KVM and chucked a few VMs on.

It kept locking up after a while, like an overheat.

I took it to my local PC repair shop who said to take Linux off, put windows on, install the correct drivers and temp monitors and then give it a stress test.

So I did this. The first stress test pushed the CPU Temp up to 61 degrees, before there was a very loud bang, blue flash and a firework show

I think I somewhat underated the PSU

It looks like I got away with it, have ordered a new PSU (1000W).

The PC repair bloke reckons the fan should hold the CPU, and so do the manufacturer. But 61 degress (and rising steadily before the fireworks).

Anyone here know what they are doing and can give me a few pointers?

It really depends on the PSU brand, most cheap PSUs marked as 500W will hardly be able to deliver 400W but even then it should be enough for that spec, the caveat here is that the advertised wattage is spread across all voltages 3.3, 5, 12v and the CPU and the GPU are hogging almost exclusively 12v. So for instance if your PSU is only outputting 15Ax12v=180W on the 12v rail the CPU alone will kill it. check the PSU lable and see how many amps are on the 12V rail.

You didn't mention what GPU you are using.

The easiest way to establish if the PSU is the culprit is to take it to the PC shop and have them hook it to 1000W PSU and tests.

61c is rather hot, even for stupid AMD, but it shouldn't be an issue, should be able to run at 80+. No idea who suggested to you AMD CPU over Intel, their only selling point is price which might be very well negated in by the much higher power consumption over long run.

Please sir, it was Eek.

The CPU apparently consumes 220W when running at full chat. Then add in the mobo, cheap as chips GPU (ASUS 1 GB GeForce 210 EN210 Silent PCIe Graphics Card), and the 6 fans, 2HDDs and it starts racking up. Apparently to more than 500W

This link is what makes me think I need such a large PSU, and may need to update to a liquid cooler PSU and Cooling for my CPU AMD FX-9590 [Solved] - Power Supplies - Components

That said, if you look at the specs of the existing cooler ::: Zalman, leading the world of Quiet Computing Solutions :::

supports all speeds for this chip. Consider then it achieving 61 degrees when it was clocked down to 4GHz from 4.7.

Not me. Only computers in my house are macs and a Xeon based file server that no longer running VMs (they run on a box in the states now)...

It's for a server that's on all the time. Why would you use a chip that consumes 200 watts more than intel's equivalent?

That is going to cost you (5kw/h) or 50p a day more for no benefit beyond heating your server room / garage

Intel's equivalent actually consumes -20W?

No but they consume 45-80w instead of 220w...

Also they have built in video so that's another 30watts saved.

So yes you could save 200watts by buying an intel processor instead of an AMD radiator....

220W - 80W = 200W

Not all rated PSUs are the same, you tend to get what you pay for so even a cheapo 1000w psu might be next to useless in real world tests

PSUs and mobos tend to be areas people skimp on thinking that don't really matter
