As said in the title. My new computer I built with the components listed:

AMD 8750FX
Sabertooth 990fx R2.0
Corsair Vengence Ram 8GB
Sasung 250gb EVO SSD
Seagate 2tb 7200 HDD
MSI R9 280X 3gb
H100i
Corsair AX750 (refurbished)

Has been switching off no warning straight up just shut down, 3 times so far in the last 2 days. With no correlation each time it shuts down.

Once shutdown it will not turn back on without the switch on the back of the PSU being flicked multiple times. The PSU feels warmish no warmer than i would expect. I have reconnected everything and the issue still remains.

The PSU was refurbished when I bought it but I assumed it would be fine as it was manufacturer refurbed and of a decent brand.

I just wanted to get some opinions on here before I have to uplug everything and send it back of to the seller!

Many thanks,

Nico.

I gather you've actually got an AX760 and a FX 8350.

I have a feeling it's an intermittent problem eg PSU or motherboard cutting out. Double check all psu connectors are on fully, especially at the motherboard.

Was this happening with the old psu too?
