775W not enough??

[Texas7412]

I have a KDM Power 775w power supply in my system, 3 fans, 2 HDD's, an i3 3220, And a GTX 780 Ti.

When my cpu and gpu both are under load the pc shuts down as if i just unplugged it. The gpu is at stock clocks, the cpu is a little overclocked 3.6Ghz (3.30 is stock)

Is this taking too much power or what? I've had a few power supplies in the past, a 350w without the GTX 780 ti and it was perfectly fine, until i had gotten the gpu and it had burnt out the psu when it was under heavy load, it'd get hot and smell like burnt plastic.

This current power supply gets a little warm but not alarmingly warm.. Any ideas?

Thanks.

Ew ew ew ew ew ew. That power supply. Yeah I doubt it is even rated for 775w. That is likely your problem. I would replacement it and that will likely fix it. I have never even heard of that brand.

The PSU is probably causing the issue but it's not because of the amount of power consumed. It's probably just faulty.

What a crappy PSU, throw it out, you could easily power that system on a 450 - 500w PSU. Get something 80+ Gold from a reputable brand.

Almost 800W could run your System 3 times. Maybe the fact its a cheap Garbage PSU has something to do with it.

Dont safe Money on the PSU next time. Buy Quality.

It's not that 775W isn't enough power.

 

It's that the PSU you're using is absolute garbage and probably only capable of putting out about <50% less of its advertised power.

 

From what I can gather, a KDM 775W is only about a 500W power supply (on a cold day).

About 30 minutes after i posted this, My 780Ti Died on me... Horrible timing.. LOL.. Definitely getting rid of this power supply..

It's by KDM power, But labelled as a "Mi PC" which is kind of confusing but oh well.. shouldn't have paid $40 USD for this thing
