750W Enough?

post #1 of 7
Thread Starter 
Yet another thread asking if a PS is sufficient...I only ask because I had a restart with no error message while doing the Mafia II benchmark:

My PS is Antec EarthWatts 750W

My system power requirements are:

Q9550 @ 3.86Ghz
4 GB DDR3 @ 1440 MHz
2 X HIS ATI 4850 w/IceQ4 (XFired)
2 X Spinpoint F4 (RAID0)
1 X Hitachi Deskstar (320GB)
1 X Kingston SSD (64GB)
4 X 120MM fans
1 X 140MM fan
1 X 92MM fan (on CPU cooler)

Thanks for your help in advance!

500W can do that.

Whoa! That should be more than enough. Check this out:

http://www.amd.com/us/products/deskt...uirements.aspx

According to this, a system with two 4850s in it should require about a 550W power supply (but even a high quality 500W would be fine too).

So, either it was just some strange once-in-a-lifetime hiccup, or it could be something entirely unrelated to the power. Of course, there's no way to know.

If it happens again, test your memory. That's the first place I look when my computer restarts or freezes during load.

It could also be a bad overclock or like said above a random fluke

This happened to me during a time when I was powering my sig rig with the HX520 and I had a single GTX 260 in it. So, I immediately purchased the HX650 and then made a thread about it more or less to mention it for whatever reason.

As a result, I learned that I should have just kept the HX520 and that I should have just considered the little auto-reboot a one-time fluke. But oh well, at least I got a better PSU out of it I guess. Although, I really should have a 450W or something. Live in learn, though...

Ohhhhh it's much more than enough. Your error is most likely not from that PSU.

Yea my memory has been a constant thorn in my side - in hindsight 1066 wasn't a great choice for where I want to go with my overclock. I'm at the upper limit of stability right now - any further and my MemTest lights up like a Christmas tree regardless of voltage and timing settings.

Fortunately I'm getting some PNY XLR8 1600's for Christmas so that should fix that
