PSU problem
Hello, wondering if i could get some opinions on the cause of this problem please, and i apologise in advance for my lack of technical know-how.
Basically, if i turn on my computer at any point in the morning/mid afternoon, after a few seconds of booting the power suddenly cuts out. The computer then tries to restart, and the same happens again. Then it gives up and pressing the on button does nothing until i turn the wall socket plug on and off. However if i leave the power at the wall on for about an hour or so with the computer on standby, it will turn on fine and have no issue. Also in the evening the problem doesn't occur and i can simply turn the wall plug on and have the computer turn on straight away. I'm guessing it's a problem with the PSU but as i said i don't really understand it. On the side of the PSU it has this information if it provides any help: AC INPUT | 230V~, 50-60Hz, 27A ------------------------------------ DC OUTPUT | +3.3V | +5V | +12V1 | +12V2 | -12V | +5VSb | +3.3V&5V | 30A....| 32A.| 14A....| 13A.... | 0.8A..| 2.5A...| 240W | Total: 370W I've had the PSU for a while now and have long since upgraded the motherboard/ram/graphics card if that could be a cause. Also i had a snoop around the inside of the case earlier today and found that a place on the motherboard called PWR_FAN had nothing connected to it and there was a loose 3 pin cable with 1 black wire and 1 white wire not connected to anything, though i didn't dare connect it and see incase i caused some damage. Thank you for reading and whatever help you can give! |

Re: PSU problem
Taking a guess here, but if it is warmer in the afternoon and cooler in the evening, it may be affecting how your failing PSU will perform in terms of handling the extra power load required for start up.
You probably need to replace your PSU. |

Re: PSU problem
Yes I would go for a power supply 370w is a tad small for a PCIe card today while yours is not a power hungry card it still puts a load on the supply, look at a 500-550w unit for that setup, higher if you think you may at some point upgrade the video card.
Brands and Models of Quality Power Supply Units Seasonic - any model Corsair - any model Thermaltake - "Toughpower" series only Coolermaster - "Real Power Pro" series only PC Power & Cooling - any model Silverstone - any model |

Corsair's always been a favourite of mine so I'll look into it. Thanks a bunch for the quick support and information!
