PC unable to power up...but...

[brendan88]

Hi guys,

Recently I moved to the US from Asia and I brought along my PC as well.

Prior to departure, I did a check on the PSU that I have and the voltage range was 100~240v. I believe that this range was good for the voltage in US.

However, when I setup my PC after I'm in the US, I wasn't able to turn the PC on. I did a paperclip test and found out that my fancy system fan was working (although PSU fan didn't work due to PSU overkill). Apart from that, my wireless headphones seems to be charging from the USB port.

My PC setup is as follows:

- ASRock Z97 Killer
- Intel Core I5-4690k 3.5Ghz 6mb
- WD 3.5" 1TB SATA
- Samsung 250GB EVO SSD
- Cooler Master hyper 212x
- Corsair RM750W 80+ Gold ATX PSU
- Sapphire R9 290 4GB GDDR5 Tri-X OC
- G.skill Ripjaws 1600mhz 2x8GB ram

I really hope someone can help me with my problem. Thanks in advance.

where in asia did you move from and are you just using a plug adapter to connect to the mains, or did you change PSU cables?

most of asia is 220V+, whereas the US is 110-120V, so you quite possibly need a voltage converter

I'm from Singapore and we use 220~240V power cables. I've got a power cable with 125V 10A rating from Amazon as well. However, both failed to turn my CPU on.

I did a search on google and found that most of the CPU cables are 125V 10A.

possibly something became dislodged during transit?

try disconnecting everything from the PSU, then re-connect and try again

I just did that and nothing happened as well.

have you still got the original power cable you used in singapore?

Yes I do. It's not responsive. I tried it with the paper clip test as well. CPU Fan worked but when I connect the 24 pins connector back into the mobo, it wasn't on.

Might try a different PSU. I'm a tech and have had situations where I go to clean up someone's machine, and in the process of moving it from their office to the helpdesk, the PSU dies. So I guess if a PSU is wonky but not showing symptoms, sometimes moving it can finish it off.
