Power Surges on Asus motherboard after new build

[Rui Almeida]

Hello. So, I've had this cpu for quite a while, an i3 550. I've paired it with a Tacens Radis V 550W and a HD 7770. Nothing that consumes much power. I've changed my i3 today, to an i3 4170 with 8gb of ram. The only thing I replaced was the CPU, the motherboard, which is now an Asus H81M-A and the Ram, I previously had 4gb of ddr3, now I have 8gb of ddr3 1600mhz. Everytime I open World of Warcraft, or any game, the computer instantly shuts down because of a "power surge". I never had any complications with the PSU untill now. I've heard you should disable it, but I'm not sure. What's your take on it? I can use the computer normally (Youtube, Facebook, Skype) but I can't play anthing. Thank you for your time

Unknow PSU are really unreliable, so you should consider chaning it for a better quality one like: EVGA, Seasonic, XFX, CoolerMaster, Rosewill... etc.
You check this list: http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html

Yeah, but the PSU was running without any problem, untill I replaced the CPU. I don't think the PSU could be damaged in the process as it never even moved. Same case, same everything. I didn't want to invest another 50€ on a PSU, already spent 220€ on all of this.

PSU is made by Andyson so it's most likely a cheap pile(as are 99% of what they make). As with the majority of their units the voltage regulation is probably horrible and causing the boards power protection to shut the system down to prevent damage.

So, buying another PSU is the only way out? Which you would reccomend (lowest price possible, please) as a replacement?

This 750w Unit is way more than you need but for $45 it's cheaper that the good smaller units.

I live in Europe tho, Portugal to be specific. I can't seem to find any store that sells EVGA psu's =\ . What do you say about Nox, Corsair, Aerocool, Antec, Be Quiet! ?

I found those 2 brands here. That should suffice. Thanks the tips.
