Nice modding, and cool config, but Sampsa my mate, you got some strong guts, thats just WAY to weak insulation, damn.. :)

Well, Cooltek 600W has four +12V rails with 20A each so it's pretty good PSU. I have now replaced it with Silverstone ST85ZF. Also next time there will be better insulation :)

Nice benches, looking good there Sampsa ;)
The PSU seems strong, any idea who makes the internals ? I was hitting OCP with the 700W Tagan on Kentsfield under LN2 with more than 1.65V, i guess you're encountering the same limits ?

Compare: 21.1K

Nice pictures :P Wonder what the floorball game was like, I'm just about to get into it again after an ankle injury from October...

But that insulation really looks good in my eyes :)

There were some serious problems with Asus EN8800 GTX because vgpu mod with 500 ohms VR gave 2,49V! Then instead of 500 ohms I used ~8k ohms and now everything is fine. Luckily the card is still alive.

Can you tell me about the mods you did?
I havent seen these mods before...
And i wondering :p:

I do not know Kiwi, my simple Xeon3060 + single 8800gtx pulls 460w just running orthos, let alone 3D.

If I had a QX6700 and a second 8800, I bet I could pull 700w... ;)

nice score~ neway sampsa, what do u think bout the 850zf? i am thinking to buy that one but from the buyer review in Newegg it doesnt looks too good..

currently i have no problem with my TT toughpower 700w powering my oc qx6700 and single 8800GTX.. but when i test using this website, it said i need 1249watts psu :(

As I said, I was surprised myself. We tested that Seasonic with my friend who has qx6700 + SLI GTX and it passed all 3dmarks several times. And the rig was overclocked of course. 12V rail was pretty stable, at least a few times when checked with DMM

HOW DID YOU CHECK THE WATTAGE?

No need to shout :p: Just attach watt or amp meter to the wall power socket and calculate :)

i just can't believe it would be possible that's all unless we are talking about superhigh overclocks here....even then i donno :confused:

Similar to this, I don't have it myself but I will buy amp meter (they are cheaper) and calculate I know I have 220V +/- :D

Maybe u got a error in ur measuring or ur PSU have a efficiency like 40%.. ;)

My system, as it is shown in my signature, needs 360W while running 2 instances of Prime LargeFFTs and 3DMark '06 at the same time.

@Sampsa

Great results!

You are at 1.4xv, I was priming 1.6+v :) Try it..

Oh, and you do not have 8800s, they use alot of power just at idle..

QX6700 @ 1.55v, stock 8800GTX SLI = 733 watts in 3d03 GT1

Sampsa, how's your 3DMarks going now? You already got LN2 I think...?
Can't wait results.

Good Luck!:gamer:
