Pungo Posted November 16, 2007 Share Posted November 16, 2007 So, I've filled out a couple of these online calculators and the load I'm apparently going to be using, after overclocking, from 2.6 to 3.2 is around 1200W :eek:. The thing is, what I'm running now, they say I am at 1100W but I'm running fine on a 620W Corsair. Should I be concerned and possibly upgrade? The only things not mentioned in my profile is the G15 Keyboard which draws power from the PSU. My MX1000 has a power supply as well as the other attached USB devices, all self powered including the eSATA WD HD (but that uses a the SIIG SC-SAE412-S2 PCI Express x1 SATA II Controller Card because the onboard SATA controller was not compatible with WD My Books :/). I'm also running a UPS, APC Back-UPS MX 1000 with my monitor, firewall/router, modem and WAP connected along with my PC. Not sure if that matters... Edit: Added SIIG PCIe card info.

Yellowbeard Posted November 16, 2007 Share Posted November 16, 2007 That power indicator must be wrong. There is no way a single video card, single CPU system is using that much power. Your PSU is more than enough for your current system. Link to comment Share on other sites More sharing options...
Pungo Posted November 16, 2007 Author Share Posted November 16, 2007 Specmike thanks for responding! What other calculators are out there? (I wish PSU's allowed a connection so we could monitor live power consumption) That one calculator really had me worried... I found a slighlty better one though. On this site: http://www.extreme.outervision.com/PSUEngine it states I have approx 639W power consumption. Quite a bit lower than the previous site I had found but still over the 620W of my current PSU. Am I filling out this form incorrectly? I'm putting the machine at the recommended PC Utilization of 85%, 90% load and 20% capacitor aging, still dropping me 19W over my current PSU.

Yellowbeard Posted November 16, 2007 Share Posted November 16, 2007 Power Guy can give you a better estimate than me but, if you your CPU and your GPU were OCed at max speeds, they "might" use 400w combined. The rest of your system will come nowhere close to that. Many of those calculators also rate items at 100% output and with bad power consumption figures to begin with. Have a look here: http://www.jonnyguru.net/forums/showthread.php?t=3137 That guy knows his stuff. Link to comment Share on other sites More sharing options...
Corsair Employees Power Guy Posted November 16, 2007 Corsair Employees Share Posted November 16, 2007 Specmike thanks for responding! What other calculators are out there?

I'm putting the machine at the recommended PC Utilization of 85%, 90% load and 20% capacitor aging, still dropping me 19W over my current PSU. Your processor is rated at 130W TDP by Intel, overclocking it may add another 20-25%, so let's add another 35W just for grins, total 165W. Your GPU uses about 160W, again, overclocking could add another 25% or so, so let's call that 200W. Each hard drive is about 15W max. That's 90W. Add about 70W for everything else combined. Total would be probably 525W under nightmare load conditions. During gameplay you'll probably only be consuming 450-500W or so, if that much. I'd actually be surprised if your system uses over 450W in real-world scenarios to be honest, unless you tried burning a DVD, encoding a few movies, copying files from one RAID array to the other, and running a graphics intensive game (Crysis or UT3 or something) all at the same time. This is actually a great match for the HX620, since the fan won't need to spin up all the way and you're not stressing the PSU significantly. You've got a nice rig there, though! Sounds like a real monster! Link to comment Share on other sites More sharing options...
Pungo Posted November 16, 2007 Author Share Posted November 16, 2007 Thanks for the input fellas! I'm much more confident with my impending venture into the overclocking scene than I was prior to this post. :D: Link to comment Share on other sites More sharing options...
Pungo Posted November 16, 2007 Author Share Posted November 16, 2007 Absolutely Power Guy! This rig is a monster and I couldn't have gotten it here without the help of Corsair's finest :cool: Link to comment Share on other sites More sharing options...

A lot of people make the mistake of selecting quad cpu (4 sockets) instead of quad core (single socket) in the online psu calcs. Link to comment Share on other sites More sharing options...
