How much power do i need

post #1 of 7
Thread Starter 
Ok you guys probably see these threads everyday so sorry in advance

i want to know if my seasonic m12d 750w powersupply will cut this.

I want to run the following...

i5-2500k at as high as possible clock. lets say 5.1ghz at 1.38 for now?
8gb kingston hyperx ram 1600mhz.
1 7200rpm samsung f3 hard drive.
1 200mm LED fan.
1 200mm non LED fan. (these are haf-922 ones)
4x 120mm non led fans.
3x 120mm led fans.
XSPC rasa watercooling 360 kit.
and 2x gigabyte gtx 560 tis overclocked, lets say 950/2300/1.15 volts each.

i also use a logitech g35 usb headset, a logitech g110 keyboard and mx518 mouse.


The guys i asked at the store are reputable and said my 750w m12d powersupply is a good powersupply and that it would handle overclocking and sli 560s. however i used a power supply calculater and it said i was going to need like 850w and that was when i didnt put the water cooling kit in or the overclocked cards, but it didnt have an i5-2500k processor either so i used an i5-760 and overclocked it to 5.2ghz at 1.4v.

thoughts? im thinking about upgrading so i can play all the awesome looking games that are coming out at 60fps like RAGE and BF3

i know there are people on here with sli 580s that will say i wont be able to max them out but my single 560 and 3.8ghz i5 still looks awesome, so this upgrade should still astound me hopefully

It has more than enough power. PSU calculators should be avoided because they're almost never accurate; which one did you use?

Even a top-quality 650W power supply would be enough.

uh i think it was an antec one, i nagivated away from page now sorry ill have a look again

AWESOME thanks dude, i thought 750 may be enough for a mild overclock and sli 560s but that adding in the watercooling pump and heaps of fans would pushing it then having higher volts for cpu and cards would ramp up the watts heaps

thanks

edit: it was the eXtreme power supply calculator

Ah ha, I thought it was the eXtreme Outer Vision calculator.

It all depends on how you use it (what settings you choose, etc.). I think these settings are the most important to consider:
  • System Type - it should be "1 physical CPU" unless you have like a server motherboard with two CPU sockets
  • Motherboard - typically for people like us, "High End" is good
  • CPU Utilization - 90% really is the best, and 100% is a bit unrealistic
  • Additional PCI Express Cards - some people think this includes video cards, but it doesn't
  • External Devices: do not include the keyboard and mouse because this calculator already takes them into consideration
  • System Load - this is referring to every single part of the entire system. That is, it's referring to everything that's being powered by the PSU. So this includes the fans, hard drives, optical drives, lights, etc. Just, everything. So, 70-80% is the most realistic.
  • Capacitor Aging - when considering the future of your PSU, I recommend 10-15%.

Any other values than these specific settings above and result in a much more inaccurate result than you'd otherwise get (it's always going to be inaccurate, but using the right values gets the most accurate results possible even though it's still inaccurate by nature).

You're very welcome!

I know the feeling, too: I upgraded to my sig rig from a prebuilt system that had a 500 MHz Pentium III, 384 MB of memory, a Voodoo3 3000 AGP, some old hard drive, etc. Except, my sig rig was born with an E2180, an 8600 GTS, and 2 x 1 GB of high performance memory (mushkin "HP" series - one step below their "XP" series). So just that jump was exciting enough.
