Just want to make sure...

post #1 of 8
Thread Starter 
I upgraded my PSU from an Antec TPQ850 to a TPQ1000 for some extra wattage and the color scheme a while ago, and am wondering if it will hold up to what I'm getting ready for...

I have a custom watercooled case with quite a few fans, a couple pumps and lights.

I also plan to push my i7 920 to 4.4+ with ~1.5v.

Now I did this with my 850 and GTX260 core 216 SLI for a while and everything was awesome. However now I have a GTX480 and am planning on getting another and putting them under water and adding volts. Will this psu be able to hold up?

I really think it can, but I'm concerned about the loadout on the rails. I sleeved all the hardwired cables and opened the PSU to do so and as I recall the PSU 8pin is on one rail, and the 8pins for the GPUs are on two others... Then all the rest (24 pin, molex, etc. are on the last) I'm wondering if anyone had a schematic so I can see how the rails are set up... I may be cutting it close and don't want to overload a rail...

rep for any insight! ;p

You will be perfectly fine, I dare say you would have been fine with the 850W
post #3 of 8
yeah the 850w would have been fine
i had a near-identical system on a corsair 650TX once (but that was pushing it)
Dont think there is any danger of overloading the rail.

Haha ok, thanks guys. I was just wondering because I know these i7s take a lot of power with volts and SLI GTX480s even when not overclocked are hungry.

Actually TPQ-850 has rather low +12V rating, so might not have been able to run it.
post #7 of 8
I think you'll be fine. A healthy 750W could probably run that

The TPQ850 has a 12v rating of 768W.
The TPQ1000 has a 12v rating of 840W.
Pretty close. :/

What 12v rating would you suggest?

I'm going to be super pissed if I did all this sleeving just to get a new psu...
