Hi all,

First time being on these forums just stumbled across and looks like a great place to get a few answers.

I'm having an issue with my PC in that my psu is blowing up on me, I've had my rig for two years now and just before Christmas I started seeing issues with my rig restarting or shutting down due to what it says on the boot screen 'power surges detected' every now and again and also my graphics card would crash when trying to load up games. And shortly after it just stopped working.

I replaced the psu with a decent 700w psu and everything has been fine and back to normal, no issues until this morning when I booted it up and after half and hour it started with the rebooting problem and then an hour later it blew the psu again.

I'm abit annoyed as it's been less than two months now and I'm really not that savvy with computers to understand what's going wrong here.

I keep all the fans and case clean, and temperature reading on the front of my case never goes above 26-28 degrees centigrade so don't think it's a cooling issue.

Any help would be greatly appreciated on this.

Thanks in advance,

Kyle

Ah, that mobo has Asus anti surge feature which doesn't always work well. That PSU is fairly new and has
the normal protection features, so I suspect the anti surge feature is the root of your problem.

I've even read on some forums, that Asus tech has advised some users to disable the anti surge.

You can disable that in BIOS, your issue should disappear.

Hi - how do you know the 700w PSU is decent? Normally the better quality PSU's in a brands line are at the 50, not 00, like 550, 650, 750, etc.

What is the brand/model of your PSU?

There are other possible causes (altho it sounds PSU related), dbl check & make sure eveerything plugged into the mobo is plugged securely. Also, run memtest on each stick of ram separately. It will need to run for quite a bit of time to be reliable. Prob 8 hrs each stick.

There could also be a mobo failure and/or a GPU failure, altho it does appear to be PSU related. You want to be sure. Hopefully the PSU is still under warranty. Seeing as it's fairly new it should be.

Hi - PSU should be OK, there are no reviews of it from trusted review sites however (Hardware Secrets, jonnyguru, Hardocp).

What is brand/model of your mobo?

PSU may be ok but i did not see any good reviews from trusted sites, and cooler master has bad reputation of their psus. I still believe it is caused by psu but it may be anything. I had similar issues because my fan controller was short circuiting. But if it is not psu it is probably mobo.
