I am building a new system and i am not sure if the PSU is enough

this is my system:

CPU: C2D E6600
RAM: CORSAIR XMS2 DDR2 PC6400-800MHZ 2X512MB
GPU: ASUS EN7950GX2
PSU: THERMALTAKE W0101 TR2 POWER 550W
HDD: SAMSUNG HD401LJ 400GB SATA2

My system has 2 more SATAs, another dvd, floppy, sound card, and a few case fans with a x1900xtx, and pulls 235 watts at load according to the meter on my Thermaltake purepower psu. (FEAR)

So yes, you should be more than adequate for the rig you described.

I laugh at the 750+ psu's some folks think they need. Most high end rigs, sli/crossfire included, pull less than 550w from the wall. Having a kill-a-watt to measure actual vs wild guess helps too!

Quality almost ALWAYS matters more than quantity.

I ran my dell 3.2 p4 with dual sata, dual dvd, 1.5 ram, floppy, misc add -ons, and the x1900xtx on the stock 380 psu with nary a blip for 6 mos. I did upgrade, as I was worried about the 12v rails.

700 watt psu's? I'm just fine w/ a 550 and it doesn't even get hot while it's running.

In general, I agree, but if you are significantly underpowered with the best quality PS, bad things can happen. Quality units are typically rated more conservatively and are rated at temps commonly encountered at high load. So if you use a power supply calculator and then buy a low quality unit that is rated at 25C and for peak load and use it right at the calculated value, you could end up singin' the low down dirty Power Supply Blues.

To the OP: do you intend to OC? Do you expect to go to a DX-10 GPU? If so, you could run out of juice once you upgrade the GPU. Your PS is decent quality but I would not recommend running it real hot.

Everything looks fine that is until you add your graphics card and oc (not mentioned)
add a few drives and your pushing it.
Just to be on the safe side I would get better.

I ll oc it and I ll go for sli with the new DX10 cards in about 4-5 moths but when i do that i ll buy THERMALTAKE W0099 SP 250W VGA PSU. So i think that i ll still be ok.

I see no problem with that Idea if its cost efective.
thought about that myself.

true, but from what i have read both GPU's from ATI and Nvidia, will be maojor power suckers. i read that they'll need 180w per card.

This PSU is made for those cards and it is in nVidia 7950GX2 PSU support list, so i think that if they can handle 4 GPUs i ll be fine.

From experience its best to be prepaired.
the last thing you want is a weak psu.
here is an article to read through that has been covered many times already on this forum

i think it will be fine,i have an antec neo 550 he psu and its working great for my setup. i have 2 dvd/dvdrw drives, a floppy/card reader and 3 160 gb hard drives plus the 2 7800 gtx cards in sli and 2 120 mm fans. i actually had all that going with a 480 watt antec unit but decided i should step up some
