can use this PSU for this build ?

i would go with a 850watt just in case of future crossfire or sli setup and o/cing.

this should suit you well :http://www.newegg.com/Product/Produc...82E16817139009

or this one if you want modular cabling: http://www.newegg.com/Product/Produc...82E16817139011

yea 850watt might be overkill for some, but if was going to dual vid card you would want that extra wattage to were you would not be running that 520 or 600 at full wattage at all time. that is a reason why psu's die, running them at full wattage intake and blowing caps.

even 300 watts is cutting it close, im sure it might be fine if you are running a low end videocard, one hd, and one optical and the cpu and ram with no o/c would be fine, but i would at least buy a 550 for it, just for the head room.

you just need to understand man, the psu is so damn important. Without a good one you are running the chance of it failing because of stress and it could take your whole rig with it I would just save up a little more and get a quality 80+ certified psu (500-600w is perfect).

well... I have just tried it, so I supplied it with the following information:

CPU: 1 Core 2 Duo wolfdale 3GHz. (TDP: 100% LOAD)

RAM: 2 sticks SDRAM DDR2.

Video Card: 1 Video Card.

HDD: 1 IDE 7200 RPM ( my HDD is SATA 7200 RPM, 16 MB Cache, so I don't know if I supplied the correct info about my HDD ).

drives: 2 DVD-RW/DVD+RW Drive.

PCI cards: x1 56 KB modem + x1 satellite TV tuner. (Technisat Skystar 2) .

USB: 4 USB devices .

system load: 100%.

Note : as for the TDP and system load, I just chose the 100% to see what will be power consumption in my system if I really use it in 100% load.

and the result was that my power consumption is only 225 watt, but I don't know how far I can trust this information though ?

Yes, that is correct. However, it is very important that you take in consideration capacitor aging. I don't know how long you have owned your PSU, but if you've already had it for a couple years, you should set that at at least 20% yet I still believe you will be totally fine.

Overclocking your CPU will also draw entire different wattages. Not to mention if you plan on pumping up your voltages to do so. If it were me, I would go ahead and keep what you have, but do no overclock until you get at least a 500w PSU. Another thing you can do for a little more peace of mind is to leave out one of your DVD drives until you upgrade. You video card doesn't even require additional power. I wouldn't stress on it too awfully much.

One of the very best investments you can buy(other than an adequate PSU haha) is a Everest Ultimate Edition system monitoring software. This is a great way to monitor your voltages. I would download the trial version after you install your parts to monitor your system under load. That way you'll know if your voltages are dropping. I still say that you will be just fine. FSP is a good brand for power supplies. However, it can be just as damaging to under power some components as it can be to overvolt others.

I hope that helps.

yes... you really did well with me, but this phrase wasn't that clear to me:

Quote:
so could you please simplify it for me?

when an FSP PSU can damage a part or more of a PC whether by under-volting, or over-volting ??

Quote:
A multimeter is much more accurate and cheaper.

Quote:
Uh, what are you talking about? There are some good FSP-made power supplies that won't damage anything...

Quote:
I'm sorry to confuse you there. I was bringing up something you didn't even ask about. In my defense that phrase was actually two different sentences. I kinda ran them together, even though different topics.

Quote:
I agree. That's was I said. FSP is a top brand for PSUs. I think he will be just fine with it as long as he doesn't overclock.

I was referring to under powering other components such as graphics cards. High end VGAs can draw a lot of amps. I was also referring to overclocking and overvolting your CPU and MB components. This can damage them as we all know. I was mostly babbling on about more information that he didn't ask about. Off topic stuff.

In what way is FSP a "top brand"? The best OEMs of late are Delta, Seasonic, and CWT (and maybe another I can't think of right now).

Okay Mr. Arguement, FSP has been making PSUs much longer than many of the so called top brands right now. It's a matter of opinion. Didn't you just argue the fact that they are good?

Also, I don't know where you are going to get a multimeter for $40 that is going to give that information as easily to use as Everest which will show you as accurately to whatever decimal amount you want every voltage of concern on your entire system. Besides, you can get Everest for free if you just search for the promotion. I got Everest, Sandra and 3d Mark Vantage free that way. How about you go find that multimeter that will tell me the votages of my MCP, SPP, and vdroop for that matter. -Not to mention logging the differences between load and idle.

I don't get why there has to be some guy from Dementia or wherever that is that gets off on arguing over issues not even pertaining to the topic of the thread. I like being able to help people out, but it never fails... .. . There's always that guy out there saying, "Nuh Uuuh!"
