Solved: Have to power cycle psu after computer is left alone

[trolatree]

Whenever I turn off my computer or let it sleep for a decent period of time, pressing the power button on my case causes the fans to spin for a second then they stop. Pressing the button again does nothing. I then reach to the back of my PC and cycle the switch on and off. I am then able to press the power button and my computer then turns on.

The specs of my PC are as follows:
Intel i5 4690k
Asus Z97-E
MSI twin frozrIII hd 7850
Some low voltage 8gb Samsung memory
430W Corsair CX430
1 TB Western Digital Caviar Blue HDD
Kingston HyperX 3K 120 GB SSD
NZXT h440
Windows 8.1 pro 64bit

I did do a mod in which I changed the voltage of my case fans so that they were not as loud.

Well you are using the wrong power supply for you system so I'd start there. 430 watt power supply is pretty low for high-end system and it's a basic power supply for basic systems even according to the manufacturer: http://www.corsair.com/en-ca/cx430-80-plus-bronze-certified-power-supply
Realistically you should have a 600 watt or higher unit and from a series designed for high stress such as the Corsair TX, HX, or AX lines or a higher end Seasonic power supply.

The Intel Core i5-4690K processor uses 88 watts and the MSI HD 7850 Twin Frozr III graphics card uses 130 watts.

Add the wattage requirements for the motherboard, RAM, hard drives, etc. and you're pushing the limits of that power supply.

Rob is one of the hardware experts here, so I would follow his advice.

Ok thanks, I have been looking at getting a modular power supply after my upgrade to the i5. I just didn't think that was the problem because it has never had a problem while running. Thanks for the help
