Weird issue with new build pc

[Tonoko]

Hello, yesterday i build myself my first pc, the specs are:

Cpu: i5 4670k

Gpu: amd radeon 7950

Psu: corsair rm550

Mobo: msi z87-g43

Ram: crucial ballistix tactical tracer

Case: cm 690 iii

When i built it, it started up into the bios, it was late so i closed up the side panels and went to sleep, next morning i wanted to install windows so i tried to turn the pc on, when i turned on the psu all leds did go on and the fans spinned. After less then a second it stopped and the psu gave a single click, when i clicked the power button but nothin happened so i turned off the psu and all the fans and leds turned on again for less then a second. I then opened up the pc and reseated all the cables, but i still have the same issue. Can anyone help me?

Thanks in advance

I read somewhere that the PSU isn't powerful enough to drive the 7950 they are pretty hungry

550w should be plenty for a single 550. and its RM series so i think its 80+ gold.

Yeah its 80+ gold but i find it weird that everything turns on for a brief moment when i turn off the psu

this is what I read: http://www.tomshardware.co.uk/forum/341514-28-3570k-radeon-7950 

 

but the calculators seems to say that your PSU is just fine for your components: http://extreme.outervision.com/psucalculatorlite.jsp

can you maybe try booting without the gpu?

Just the power cable unplugged or the whole thing unplugged?

[chicksoup]

take it out of the motherboard, if it works then the problem must be related to the gpu

[Tonoko]

It still does the same thing, ps the power led doesnt work when everything spins for a sec

[Tonoko]

I think because the fans spin when i plug the power cable into the psu

[Alex780]

It has nothing to do with the power your psu is able to deliver. If you had a problem with that your pc would turn off by itself only when gaming or when it is under load. I had the same problem as you with my mom's pc. I'm not even sure this problem is psu related. The motherboard could rather be the cause of the problem.

That would be funny, mobo defect after 1 time in the bios...

could there be something inside the case causing a short curcuit? otherwise I have no idea what the problem might be, but because you hear a clicking noise in psu is sounds like a safety mechanism

 

 

are you also sure that you are powering the PC on?

[Tonoko]

Yeah im sure that im powering the pc on, but what do you mean with a short circuit, what for example?

[Prokart2000]

500w might not be good for that because my r9 280x (7970) needs at least 750w and I have 800w and still need bigger

[Tonoko]

It did run at first...

[Prokart2000]

Also it could be a short check to see if the mobo is touching the case or stuff like that

[Tonoko]

So i dont understand why it stopped if the psu is too small

[Tonoko]

I did that already

[chicksoup]

when I hook up my pc to the power it sounds like it's going to power up, but then stops( takes about 1 second) so I really feel like it's not being booted correctly

[micedits]

Are you sure the system is properly powered? I do not mean in terms of wattage, are both the 4+4 pin and the 20+4 pin power connectors correctly in the motherboard.

welcome to the world of MSI, their firmware is dreadful

[Alex780]

Did you wear an anti esd strap? Do you have carpeting in your room or anything likely to cause an electric static discharge?

I did like 9 bios and ME flashes plus tons of tweaking in my bios and never had any severe issues with my MSi board

you must be one of the luck ones then, i had my board for a week then i had to RMA it, every time i got it back it was the same some problems every time, in the end they send me a newer model and it took that one 3 week then the same problem firmware messed up even the backup bios.
