how accurate is this program?
the reason i ask is i am looking for a power supply for a new build and unsure of EXACTLY what to get.

here is what i will be running:
Q9550 Overclocked
EP45-UD3P
4GB F2-9600CL5D-4GBPI overclocked
9 140MM fan's
2 120MM cpu fan's
1 80x15MM case fan (CM690 II Adv.)
Lamptron FC-6 controller
160GB SSD
1TB Storage Drive
CF 5850's - (maybe CF Future ATI Cards)
4 External Storage Drives
A few LED's
.......................................
possible custom water loop in the future

the calculator shows Rec PSU Wattage @ 729 Watts

my budget is around $200.00 and it needs to be modular.
my original plan was the Seasonic X750 but i am worried that 750 would be cutting it to close. I have read that the CORSAIR HX Series was a good way to go, should i future proof myself and go with the CMPSU-1000HX or the TPQ-1000 ??

any input would be greatly appreciated..

an 850wHX corsair unit is all you need.

Remember, that most of the high end PSU's can do more than what they are rated for.

For $200, you could go all out and buy a nice 1 kW PSU. You'd definitely be future-proof with it.

Unfortunately, those PSU calculators aren't as accurate as we want them to be. So it is best to do exactly what you're doing and ask on good message boards.

For this system, a high-quality 700-800W would be just fine. But if you ever decide to Crossfire some higher-end graphics cards (like let's say something of the 5890 caliber), then I would recommend something between 800W and 850W among the high-quality PSUs.

But the Seasonic X750 is a damn good choice and it's better than Corsair's HX series.

As far as a 1000W unit, well I don't know about the HX1000W or the TPQ-1000, but I do remember that there are better units than these, however I just can't remember what they are right now. But still, the Seasonic X750 is an excellent choice.

well i might just go with my original plan and do the X750. what's the worst that can happen, i have to buy something more powerful later down the road when i upgrade cards and go i7 or something? i think the X750 should work well with CF 5850's and the Q9550

And even the i7 920 or something. If I had extra money that I didn't need, then I would most certainly replace my HX650W with the Seasonic X650!

Each PSU calc will be different. The one Asus.com uses says I need a minimum 600W for my system, this one says minimum 400W. Which is correct? IDK. I'm currently using a 600W with no problems.

 

[Phaedrus2129]

Generally the Outervision one is the most accurate, and is also used by a good many other websites. The Newegg one is by far the worst, don't even bother with it.

A high-quality 400W would actually be ok in your system. But I'm not trying to say that the other PSU calculator is correct.

Well, I actually purchased a barebone kit from Tigerdirect that had this board and some other components, including the PSU. It's not that I went on Asus's recommendation, it's just what I have. Just a question though, if I were to put say a Phenom II x4 965 in here, or the new 1055T, do you think I'd need a bigger PSU than my 600W?

According to that calc, the minimum I would need is 443W.

I guess you didnt read this "The recommended total Power Supply Wattage gives you a general idea on what to look for BUT it is NOT a crucial factor in power supply selection"

 

[hick]

ACtuallly that calc is not to far off from all of my builds, compared to my kill-a-watt meter within 20w.

Since this system (even with the Ph II x4 965 or 1055T) has the GTS 250 in it - and also considering all of the other components - even a top quality 400W would be fine. The GTS 250 is almost perfectly identical to the 9800 GTX+.

I have seen a few high end systems here on OCN that have the GTX 260, and their entire systems were being powered by the Corsair VX450, another was some 425W Codegan, another was the 380W Antec Earthwatts, and still another was the Corsair CX400W. So then why do I have the HX650W? hehe because I wanted it!

I upgraded to the GTX 260 from the 9800 GTX+, and back then I had the Corsair HX520W. At one point in time, I had some system issues and so I decided to ask OCN if it was my power supply; every single reply lead me to one conclusion: my HX520W was serious overkill for my system at that time. But this doesn't mean that every single 500W power supply would be serious overkill.

This is why we go nuts over picking the best power supply possible.

So I'm saying that the current PSU you have should easily handle such a CPU upgrade.

I've run my system in my sig, with ANOTHER gtx 260, and it was still fine.

Damn; two GTX 260s on the VX550W. Nice!

 

[Th0m0_202]

just add 100-200w on what ever the caculator says and all will be well in pc land

Only if you buy a cheaper power supply. If you get a really good one at the rated amount, you'll be fine.
Remember, cheap ones tend to exaggerate their output a lot

A few extra $$$ on good power is always worth it.

I have yet to find an online PSU calculator that remotely jives with my own testing. Your system would do well with the previously suggested Corsair 850HX. Assuming you don't have it running at full power draw 24/7, I suspect you'd see better 24/7 efficiency with a 750HX, given the HX series efficiency curves. However, the 850 may be a better long-term choice when future upgrades and capacitor aging are taken into account.
