Toughpower 750

[itotallybelieveyou]

Can a Thermaltake Toughpower 750W handle Q6600 and dual 8800 gtxes with 2 7200rpms in raid 0? with all the other standard dvd drive cpu fan mobo 2 120mm fan onboard audio

Yes.

The higher end Thermaltake Toughpower PSUs are good and the 750w will be more than enough.

Non Toughpower PSUs are at best average, but I digress.

I don't mean to hijack the thread, but will I have any problems fitting the Toughpower 750 in an Antec Nine Hundred case?

Also (like I asked in another thread), I've read that many people have had noise issues (buzzing) with this PSU - does anyone know if this has been solved? And what are people's general experiences with the TP750?

To the OP: According to this thread, for GTX SLI 850W is recommend. (Just relaying it, don't know if it's correct.)

 

[akhilles]

It should fit, as there's nothing at the bottom of the case:

Great case

Pros: Excellent case. Very quiet. I have had this case since 10/2006 and just bought another one for a second machine. Bottom mounted PSU works well for me.

Cons: None.

Other Thoughts: DFI Infinity 975x, E6600, eVGA 7950GX2, 2GB Corsair XMS2 DDR2 800, 750W Thermaltake toughpower PSU. I run all of my games at max settings without overclocking but if you feel the need this case should provide more than enough air flow.

I want some of whatever those guys are taking. I think they should just say minimum 5kw across the board, then they will be sure and be safe. I ran the Xtreme PSU calculator with the following:

1 Q6600 100%TDP OC to 3G @ 1.3V = 142W
2 8800 Ultra in SLI
2 SATA HDD
2 DVD-RW
1 Sound Blaster card
3 120mm LED fans

100% system load

Recommended PSU 579 Watts

SLI Zone 950-1200W WTF?

 

[spaztic7]

I do not agree with Jonesy1499. I have the the Thermaltake Toughpower 700W and that will be about 200W short of running SLi with a q6600 and 2 7200 hd in raid 0. I have a q6600 and 2 7200 in raid 0. The ultra needs 350w at max (during gaming) and the gtx needs about 250w-300w at max (during gaming). I have a 8800 gtx bfg oc2 and that is just 6 MHz slower then a stock ultra. I figured I will need at least a 900w psu.

They make video card psu that are 250w and a 350w. They are on newegg.com. The 250w runs about $55 and the 350w is about $85. I am looking to buy another 8800 gtx bfg oc2 this winter in a new card with reasonably higher gaming yield dose not surface from Nvidia, I find that the 350w will give me enough to run a ultra (or my card) with out a problem.

I would hate to see your performance take a hit because you can give it enough juice.

I could have sworn I thought I saw 2 GTX's in SLI would comsume up to 50amps (600watts). Maybe it was a different version of the 8800 GTX, OC'd higher by a specific brand.

All I know for my GTS, it consumes 50watts more, regardless if idle or games. It cuts my time on my UPS by 10 mins...

Not a chance, not even remotely close.

 

[Grimmy]

Edit:

Now that I think about it, perhaps back then people were saying a single rail of 50amps, and at least 30 amps for 12V1 and 12V2 for the other route on SLI PSU.

Bah... It's been so long ago. :sigh:

 

[spaztic7]

lol.... I saw a review showing that a single ultra uses 351w at max. Since I am only 6 MHz slower then an ultra, I assume I must run a psu as an ultra. It’s safer that way.

 

[Grimmy]

So are the recommendations on 8800 GTX products.. over rated ? :?

I mean I do see 28 amps for EVGA 8800 GTX. So having 2 in SLI mode, what would be the exact requirement of power?

 

[khaz]

FYI

I had a Toughpower 700W that developed a droop so bad after 6 months that it became unusable in an overclocked system. I replaced it with a Corsair 620W. I recommend looking at a Tier 1 PSU if you are putting together that power-hungry of a setup.

 

[Zorg]

I did a little test with the eXtreme Power Supply Calculator Lite v2.5. Assuming it can be trusted, and I think it can, follow my logic.

Using all default settings in the calculator
Recommended PSU
Regular mobo Q6600 1 stick DDR2 and nothing else 119W
Regular mobo Q6600 1 stick DDR2 1 8800 Ultra 239W Difference 120W / 12V = 10 amps
Regular mobo Q6600 1 stick DDR2 2 8800 Ultra SLI 342W Difference 103W / 12V = 8.583 amps

So 2 8800 Ultras in SLI = 223W / 12V = 18.583 amps.

Ignore the Recommended PSU wattage figures and concentrate only on the differences.

I don't know why the second 8800 Ultra is only 8.583A and not 10A. I'm not even sure the calculator is correct. Just something to think about.

 

[Grimmy]

I basically use that as well.

I can understand your logic, but I'm thinking more of recommendations towards a fully equipped tower or mid case. But then I guess most markets want you to purchase a nice PSU. :lol:

When I plug in the figures for 100% TDP (of a typical fully loaded system):

Highend MB
Q6600
2 sticks DDR2
2 HD SATA
1 DVD-R
2 SLI 8800 GTX's
Sound blaster
TV Card
4 Led 120mm fans

Total of 501 watts. I usually taking in consideration of 80% for a comfort zone. So for 750W, which is: 600W. So that's even good the way I see it.

So, I guess I can't seem to remember where I saw the 50amps needed for 2 GTX's. I do recall saying.. Wow to myself when I read it. :lol:. o O (don't think I'd have 5 mins of UPS power if I had 2 GTX's if 50amps were needed, and there was a blackout at my house)

 

[spaztic7]

Wait... so... is that your current system grimmy? Because that is amazing if it is.

And what did you mean when you said "So for 750W, which is: 600W."?

I have 4 sticks of ddr2 800 oced to ddr2 1000 (all at 2.0v), q6600 at 3.2GHz, 2 hd in raid 0, 5 120mm fans, 1 8800 gtx bfg oc2, x-fi fatality, and a thermaltake thoughpower 700W. So in theory I should have enough power from that one PSU to power my system pulse another 8800gtx bfgoc2?

I AM SO CONFUSED, PLEASE HELP!

 

[spaztic7]

Are you using the lite version or the Pro version?

 

[Zorg]

Lite version.
Understand, I was only trying to find out what the 8800 Ultra was drawing by itself, which appears to be 10A and 8.583A respectively. You need to add the current for your other components. My only concern is all of the confusion about what these cards draw. Nvidia etc. is very nebulous about the current (amperage) requirements, intentionally so I suspect. They talk about minimum current on all rails etc. Now you know what the card itself draws, according to the PSU calculator, and you can make a more informed judgment. The whole current draw concern is made more confusing because some of the required current will be drawn from the PCIe slot itself, while the balance will be drawn from the PSU connector directly.

For a note of contrast, I've had a Toughpower 700wt for over a year in my gaming computer and I haven't had any PSU related problems. Further, I live in an area where the electrical supply from the wall varies a lot. I use a UPS to balance that, but it isn't easy on hardware.

I also find it amusing that you changed to a Corsair PSU and then recommend tier 1 PSUs, as the Corsair is a tier 2 PSU, same as the Toughpower.

To the OP, I don't think the hardware that you listed is super demanding. A Toughpower 750wt should do nicely, unless you add TEC coolers or a bunch of other power hogs. As for the buzz that Jonesy brought up, Jonnyguru.com writes of hearing one, but I've never heard such a buzz in my Toughpower 700wt. It may be there, but is covered up by the noise from the fans, the video card, etc. Jonny did not test the PSU in a running computer, so he might have heard some noise that the average person would not. By the way, there's been a fair dicussion of PSUs on a separate thread, "+12 Volt Amp Rail Rating". You might want to look that thread over a bit.

No... I was pluging in stuff on the free calculator on what I think a fully loaded system would be.

I generally take 80% of the total power (750 X 80% = 600), and use that figure to put a system together. (back in the older days) So that way there's a comfort zone that allows the PSU to breath while it's under full load by all other components. :lol:

Looking at your spec's... and using that free PSU cal, I came up with: 514W with the OC info you provided.

I actually use whats called a kil-0-watt meter, which you plug appliances in to get a wattage reading.

My system is basically:

E4400 OC to 2.8
8800 GTS 320mb
2Gigs 2X1 A-DATA Extreme CL4
1 SATA2
1 DVD-R
3 120mm Fans
1 140mm Fan
6-Fan (4 adjustable 2 toggle 12v/off/5v) Controller
SCSI Card - for old mustek flatbed scanner

On the kil-o-watt meter, using 3dmarks 03-05, my system only used 270W at peek. 50W more then my older system. And I use a 620W PSU, I've done the calculation of my parts on the calculator, which was 327W. So there's a difference of 57W more that the calculator registered.

This is the meter I use:

P3 Kill A Watt Electricity Load Meter and Monitor

So ya, I think you'll be okay with the 700W.

OK, Well I am putting my faith in you. How confident in this program are you? I am not trying to burn you or anyhting of that nature, I just can not afford to blow a part or anything. So If I do run SLI and IF I do blow up a art, will you relpace it for me? lol....

 

[sailer]

If anything, the eXtreme PSU calculator overestimates the amount of power needed. I myself have good confidence in it, but like all such things, its only as good as the person who feeds information into it. In other words JIJO.

Ahhh.... I learned that back in highschool.... to bad I can't retain stuff to well... (makes me wounder how I remember learning that in highschool now...)
