PSU Enough

post #1 of 27
Thread Starter 
Long story short, on my old i7 920 build overclocked to 3.5 I went to go put two GTX 580 lightnings in with my 1200w corsair psu, and the psu blew and shot the board as well. Due to some other circumstances I chose to just upgrade and I went with a new asus board and the 2600k processor. This all happened right after putting my two new cards in. I am here looking for some confirmation that 1200 watts is more than plenty to power up my system with two 580 lightning cards. Someone please help me out.

All my current specs are in my signature, with the exception of the sli. Do you guys think 1200 watts is enough for 2 gtx 580 lightning cards judging from the rest of my system specs?

It's enough, but I think you just had bad luck.

Guru3D was able to get their test system with two GTX 580s in SLI to pull 719W from the wall outlet (source). So assuming 85% efficiency, that would mean that the system pulled about 611W from the power supply. They recommend adding about 150W for the rest of the system, so that would be about 760W of total power drawn from the PSU under heavy loads.

A Corsair 1200W is more than enough to power 2 580s and a i7 2600K.

Yeah, people keep telling me that the initial system bootup draws the most power, plus the fact that it is two msi lightning cards, which are already overclock and pull a max of about 382 watts according to guru 3d. I was pretty sure it was enough, it has just been in my mind since it happened. Hopefully when I get the replacement, everything fires up just fine. I was so angry when my psu just blew.

Oh, then you may have had one of the initial lemons that Corsair released for the AX1200 line. It's all worked out now and there are no more issues, so they're now just as good as the "AX" name implies.

When did they fix this issue. I only got this power supply a few months ago, however, I did buy it from microcenter. It is possible that the retial store still had some leftovers I suppose. I am calling them tomorrow about the rma. I am kind of hoping that they will just let me send in the psu without the cables. I spent a lot of time on my cable management

I can't remember, but I think it was like 4-5 months ago. I'm taking a shot in the dark though.

Anyway, I agree that since you bought it at Micro Center that it was probably just a leftover! Or, just one of those unlucky people who get a defective unit.

So, I'm confident that your replacement will be more solid than a heavy duty tank!

You're welcome, rdasch3!

I suppose there may be a small chance that they'll let you keep the cables because they've been known to give people free modular cables at times when asked. So I mean I suppose that if you keep the cables, then they'll just grab some of theirs and put them in the box once they're done refurbishing it.

My plan is to call them tomorrow and hopefully have them let me keep my cables in tact. I would hate to have to redo my cable management.
