800w enough for this PC?

post #1 of 31
Thread Starter 
Hi you guys.

This PC is new. The 800w power supply I don't know who makes it.
The main component are...
3930k
660ti x 2 in SLI.

The power supply is rated to be more then 80% efficient. Not sure what that means.
Also it says that it's SLI ready. Again not sure what that means.

So is this going to be ok or should I get something more?

Thanks.
Happy time PC.

If it was a quality 800w, it would be overkill. Now I suggest you find out who makes before you use it in that set up. Don't ever skimp on a PSU. That system will run on quality 650w or even 550w PSU no problems.

Here is a good buy on a budget.

I'm going to ask about the PSU manufacturer.
Will post as soon as I find out.

Thanks.

Ps: so are you guys saying that if the PSU is an ok brand 800w is enough?
But if its a crap brand I should Change it?

What does a bad PSU do? Lets say its a crappy PSU. What's the difference compared to a good PSU?
Happy time PC.

1. A bad psu might burn your house down
2. A good psu might burn your house down, but seems considerably less likely to do so.

Seriously though, yeah, don't mess with cheap PSUs.

Even 550w should be plenty, as long as there's no other big power consumers in the system. 650w is probably safer to allow for future deterioration of the PSU and load it lightly.

Crap power supplies have a hard time sustaining the wattage that they say they can. A 550W PSU would suffice for you.

It's like going to Mcdonalds and ordering a Big mac. Once you recieve the sandwich u realize that it has no meat and is half eaten.

Oh my god 3 buns and "special" sauce. Lololol. tongue.gif

One thing I don't understand.
This computer comes with 3 year warrant. It is in their best interest to keep all component working properly for 3 years. If they use crappy PSU and it does damage to the PC it hurts them.
Not only me. But I could be wrong.
Happy time PC.

What company did you buy it from? What is the PSU brand and model. Companies don't always give you appropriate hardware. 800W sounds alot better than 600W to the average user......
