Asus Prime Z270-A wont post

[dnewt20]

Hi there,

I am at my wits end with a new build which powers up, fans and lights go on but the POST LEDs do not illuminate at any point and there is no output to the monitor.

Having originally built the system in the case, it is now out of the case with the minimum of hardware connected:

Asus Prime Z270-A (new)
I7700k (new)
Corsair Vengeance DDR4 3200 2 x 8GB (CMK16GX4M2B3200C16R) (new)
High Power Plus HP-650-G14C ATX 650W (from a previous build which was working fine)

I have tried:

- 2 different monitors via HDMI and DVI

- the board was assembled as per the manual

- the cpu is correctly sat with no bent pins

- one stick of RAM has been tried in all slots

Please advise on how to get this working? It will be much appreciated!

Thanks,
David

Try another power supply. Your current one isn't that great

I thought that might be an issue. I'll give that a go over the weekend.

should either of these do?

My only other thought is that my RAM isn't on the QVL list - could that be the issue?

Best regards,
