Is my 400w PSU enough for my RX 580?

[elpapimejor]

Using old EVGA rn, tried with only one stick, no gpu and with gpu, and cleared cmos about 3 times already, nothing at all

 

[eidairaman1]

Switch ram stick then try in another slot.

 

[elpapimejor]

motherboard seems okay though, I plugged in the old dell psu and it has a self test button in the back, when I press it, all fans on the motherboard start functioning properly as long as I hold the buttom

 

[eidairaman1]

If not do not use the cm psu and upgrade the board, cpu, ram.

But you have no display right?

 

[elpapimejor]

Just tried all three sticks of ram I have on each one of the slots, still no luck

 

[eidairaman1]

Just because self test button claims it is ok is a false indication. If it doesnt boot from monitor hooked to motherboard it is screwed.

Check the osd settings and verify what video input you are on...

 

[elpapimejor]

Nope, no display

 

[eidairaman1]

At this rate the cm psu screwed up the mobo.

Time to consider upgrading.

Suggest a Ryzen 3600.

I’m on vga, but it’s like the pc doesn’t boot up when I press the case button, only fans spin for a second then it reboot

The board is screwed see my last message above

 

[elpapimejor]

I don’t really have enough money right now to upgrade and I’m jobless(17 but looking for one)

I kinda find it hard to believe that the board is dead because when I press the test button on the dell psu, everything comes on,case fans(plugged into mobo,) cpu fan, and also the 650 ti fan turns on as well

You are likely triggering different circuits and unfortunately, you are likely pc-less. I would ask your teacher to help you troubleshoot.

The chances of wrecking the board via ESD or the like is not none.

Unplug the front panel headers and try starting it by shorting the pins with a screwdriver. This will rule out a bad case switch.

Since it’s a prebuilt optiplex there aren’t any pinouts online for me to test that out, but, if I unplug the front panel i/o plug from the header and then switch the PSU on, the pc starts power cycling

Taking the pc to the class tomorrow for him to help me troubleshoot a little bit more

 

[Remeca]

How did that go?

 

[EarthDog]

Just finished doing what eidaraman just said but still, power light flashes and fans rotate for about a second or two and then it restarts/power cycles

"Throw it the gutter and go buy another" - eazy-e

 

[elpapimejor]

How did that go?

Looks like I killed it with ESD, since the PSU worked perfectly in another bench he had.

 

[damric]

Oh no, that's the 25'C model. Look at the sticker.

One of the worst units ever made. Unless your are blasting cold air into it, it's just waiting to die. Who would bother selling a PSU that only works up to ambient temperature?

Actually it's one of the only popular brand name PSUs worse than the original Corsair CX rated for 30'C. At least they finally revised that PoS.

Wait, you're talking about the CM Unit? Or the EVGA unit?

The 400W EVGA. See the the sticker

Those bastards. They sell good stuff like the LEADEX and then sell turds like this using brand trickery.

I don't get it like, i've ran this PSU for over two years now and ive had no problems at all, i guess the cooler is doing its job pretty well then?

What do you think about the CM unit though? I got the RX 580 yesterday and I tested it in my teacher's test bench on that PSU (CM) with a 2x molex to a single 8pin and it worked perfectly, ran cod bo3 max settings in 1080p and it stayed cool at 99% usage for about 25-30 mins

 

[freeagent]

AMD says 500w..

The sad thing is that you should never have swapped PSU's. The EVGA is a better, more modern design, even with its thermal limits. One of my basic rules for PSU's is: If it doesn't have the connections that you need, for the main parts of the system, don't use it. In most cases, adapters are trying to make up for an inadequate design.

I encourage you to watch this: https://www.techpowerup.com/forums/threads/jonnyguru-talks-about-power-supplies.261018/

My response to @damric : You're hammering the EVGA unit because you know what it's short coming are. Can you find the same openness from CM?
The EVGA unit passed on jonnyguru

Folks, this is the very bottom of the barrel for EVGA, and I still couldn’t kill it. This is the worst performing unit you can buy from them, and it’s still good enough to do some really impressive stuff like survive temperatures it’s really not supposed to. And how nice is it that they aren’t hiding that 25 degrees rating in the first place? Honesty in a company is a very attractive thing, says I.

The CM unit failed (way back in 2009) on https://web.archive.org/web/2010011...2009/02/16/entry_level_power_supply_roundup/2

About how many watts you need: Your PC is "modern", power wise. Almost everything runs of of 12 volts on today's systems and there's even talk of moving to 12 volt only PSU's. So your system has a 95 watt TDP Intel CPU that can't be overclocked, so you can take that TDP = watts used. Then the RX580, which you don't mention what model, but if we go with 200 watts, you still have, out of the 360 watts on the 12 volt rail on the EVGA, 65 watts for everything else. Please note that outside of benchmarking, the chance of having both the CPU and GPU hitting their peak power consumption numbers at the same time is very slim, so that 65 watt number is really conservative.

Please don't overlook this: Both the EVGA and CM PSU's are rated for 360 watts on the 12 volt rail, but EVGA rates their PSU 100 watts lower than does CM.

This is Guru3D's generic power supply recommendation for the series:

• AMD Radeon RX 570 - On your average system the card requires you to have a 450 Watt power supply unit as minimum.
• AMD Radeon RX 580 - On your average system the card requires you to have a 500 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

I wouldn't be caught dead putting either of those 2 PSUs in any of my builds, and I wouldn't use one for a customer's build either. I've had to replace way too many of them. Most people that spend $25 for a PSU also likely have crap airflow, probably just one 80mm exhaust fan. Then they put a graphics card in and boom.
