OnePlus 5 review
i have a hiper 480 watt psu operating an Asus m2m32 sli wifi m/board, a 4600 dual core cpu and 2gb of 667 mhz ram in dual channel.
also attached is a 120gb hard drive (SATA)
2 x 6600gt in sli mode
2 x dvd drives
1 x xfi soundcard
gigabit lan card
pulling on the usb is a logitech keyboard
logitech mx 1000 mouse and a saitek 2500 controller.
the m/b is running at stock settings at the moment although the cpu had been overclocked by about 10% before any problems. the only other bios setting changes were just the boot sequence change and turning off any onboard goodies not needed.
my problems began on wednesday when my computer failed to boot properly. it would turn on and the lights would come on for activity but no signal reached my screen. i turned off the psu at the back to cut power to the m/b, took out the battery and did a bios reset. then i replaced the original battery and turned the psu at the back switch. the computer then booted normally to the post screen,and i reset the date, time etc. and did an f10. the computer ran fine all day and i turned it off in the early evening as normal. i returned later but again it would not boot up, so i repeated the sequence from earlier and it booted ok. this has now happened every time i turn on the computer, and i follow the same process. however looking at the notes i took when doing this there is another step which is also repeated; the turning the psu off at the back switch and back on again. so tonight before i booted the system i did the on/off procedure alone and it started to boot normally.
i would appreciate any opinions on this as i think it may not be the m/b but the psu; i not totally convinced though. by the way i have also changed the m/b battery thinking it was it but it all did the same as before
Try taking the Power Plugs of DVD drives see if it starts any better. The PSU is not powerful enough. Not with the Drives and two graphics cards.
You can forget the USB they have a limit that you can put on the sockets then they cut out. it's about 500 milliamps
I had exactly the same problem a few weeks ago posted about it on another forum who suggested it was a faulty motherboard, PSU or hard drive, however after testing various parts in another computer it was the hard drive that was the problem.
So it might be worth going to your hard drive manufacturers web site and download and run there hard drive testing software, at least that will isolate one possible cause.
If you want to check your PSU, Antec do a PSU tester that costs about £12.
And Maplins also do one but I do not know how good that is.
i agree with woodchip, i really think you need a bigger psu.
i had a hiper 530 watt started to wobble with an amd dual core 2 gb ddr and a 8800.
so i would think thats your problem
take out one of the graphics cards run with just one if the problems continue then you will now that the power supply at 480w does have enough power but maybe faulty
