How to solve power issue with PC?

Wow how is it possible that your entire house is running on 110v? I believe most large house appliances (fridge/tv/washing machine) in sg run on 240v so how have you not encountered any issues all this time?

Because nowadays most appliances can run 110/240 without you needing to flip any switch on the appliances? That's why no issue all this while?

Still very strange. Cos those that can auto use 110/240v inputs ones are your low powered AC-DC equipment like handphone charger / laptop power brick/ or even tv. Those high powered equipment like fridge/ oven/ water heater cannot auto switch. They only support 1 voltage (~220v if bought locally)

Even the lights at home are single voltage only.

Waaaa sian, my PC cannot power up again, the motherboard and fan keeps switching on and off and flashing like disco light. I think the AVR probably KO-ed or something. The worse thing is cannot refund... 190 bucks flew off just like that. SP services said they can't do anything about it, ask me to approach town council because its's HDB.... So much problems for a PC....

out of curiosity and i'm not an expert at this, but can one safely measure the ac voltage mains utilizing a multimeter?

Yes u can. 3 ways.

Safest is to get a plug in power meter. Find a model that measures voltage.

Second is to buy a multimeter with a tong tester.

U clamp this over the live wire of ur equipment under load. The tong tester uses magnetic force to measure the AC voltage. This is safer cos no need to expose any live wiring

Another way is if ur multimeter support 240vac. If so just set ur multimeter accordingly and tap the 2 points across the equipment under load

AVR is normally used if u power stuffs from a generator. Sound a bit odd to use it for household power. Update us if u managed to find a solution

Hello Thyeter/others on this thread:

Did you manage to resolve this power/boot issues with your custom DIY PC at the end of the day? )

I am experiencing similar issues.
Yesterday, UNresoloved PC was collected back from SLS Cybermind, and recurrence of power loss during booting up/shutdown random is now 100%

After consulting other technicians', they mentioned 2 possibilities of root causes:
1. Residential vs. Commercia/Industrial electric power supply to entire building differs. Single-phase vs. Three-phase, the latter being more stable.
I have googled, but came to no official confirmation of relevance to SG/HDB/SP yet .. which brings to point 2.
2. Nevertheless, from these SLS tech's wealth of experience, certain PSUs (brands, models) are less reliable, they fail when used in conjunction with Single-phase power.

Take-home message for consumer/buyer is: the product should work as intended (warranty), and not be sold in unsuitable conditions, falseor hidden marketing (makers, retailers bad faith) etc.
Solution would be to visit your local distributor and get a replacement.

Bitter pill, but (i'm unsure either) problem may still persist if:
Exact product is provided. Something to be aware.

Helllooo, What will folks here do if 2nd-PSU (idential model brand) still gives issue? New / warranty how / top-up / claims / Other methods ...
