Mayfly power supply

So I'd always heard before I built my first rig, that when you're buying PSUs, always go with a trusted brand like Corsair, etc. But When I needed a PSU upgrade recently, I ended up buying a very cheap 780w PSU of a brand I had never heard of. I thought, even if it's a cheaper model hopefully it'll last until I have more cash. Nope. It literally lasted a single day before it died. I checked everything, my build was fine, I did the paperclip test, nothing. Is this really common with cheap PSUs? Or was I just unlucky? Let me know.

 

PS, it was a "HEC Compucase g7"

Yep. This happens a lot with cheap psu's.

My PSU which was an ULTRA LASTED ALL OF 45 Minutes so windows installed then boom it died. Well it had unstable voltage 5 volts down to 1 then up 9

when you get a psu you MUST GET 80+ at least, after that look at the company but if its not 80+ worthy then do not get it under any circumstances, i dont care if you have to loose a limb or stop worshipping gaben, this is a crucial matter.

That's what happens when you get no-brand PSUs, sometimes they last an OK amount of time (delivering wrong voltages) or they die almost instantly.

You bought a MayFry power supply.

HEC, if they wanted to, are capable of making some decent / good PSUs as shown on some of BeQuiet, Cougar, EVGA, etc PSUs. Apparently the HEC G7 is the platform that the Thermaltake TR2 RX 750w based on. http://www.hardwaresecrets.com/article/Thermaltake-TR2-RX-750-W-Power-Supply-Review/902/1

 

Not only did it fail to function at 600w+, it violated ATX specs on the +12v ripple somewhere in the 500w range, which can cause stability issue to your system as well as be damaging to your components if operating at such a load.

That's a shame I guess, in the end I got a return to amazon and got a much more reliable brand. No complaints.
