Hi, I am about to make myself a new computer. I plan to buy an Asus V7333 motherboard with an Asus v7100 graphics card, 256 MB DDR RAM, one CD Writer, three ATA133 hard drives and a floppy drive. Can somebody tell me what should be the minimum wattage rating of the SMPS (power supply)? Can somebody also give me pointers on how I can determine the wattage of the power supply? Thaks.

I would recommend buying a brand name psu, like antec or enermax. THG revealed the qualities of power supplies in their article, I don't remember what it was called... Anyway, I have a 300watt supply from antec, and it powers a whole lot of stuff. I would go higher then that, maybe 400 or 450, but even that may be excessive.

My suggestion is the Enermax EG365AX-VE (FMA) ....this 350W power supply will supply more +12V power than all generic and even the higher watt Antec power supplies (26A) and will serve your purpose with all your hard drives etc...and is only 70 bucks or so at newegg...

I would also recommend Enermax PSU. 350 Watt will be enough for your system.

A very good supply, 300W. An average supply, 400W.

Don't bother with Enermax unless it's very cheap because it's nothing special. A Fortron/Sparkle 350-400W supply can put out more power than you'll ever likely need (they make many of PC Power & Cooling's products and the Verax and Conrad supplies that scored so highly in Tom's review) and is cheap at www.directron.com and www.newegg.com.

A 350W Enermax/Antec would be enough.

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on :eek:

Based on what you are telling me about the specs. You will need a PSU that will supply 15A on the 12V rail. Not all PSUs are alike. Let me give a few examples.

<A HREF="http://www.newegg.com/app/Showimage.asp?style=album" target="_new">Fortron makes a good 300W PSU</A>. It has 15A on the 12V line. This is a good minimal PSU. $30 and free shipping at Newegg.com. (I have one running a Duron 1.3GHz and two others.)


<A HREF="http://www.newegg.com/app/Showimage.asp?style=album" target="_new">Here is a good PSU from Enlight.</A> It supplies 17A on the 12V rail. $39 and free shipping at Newegg.com.


<A HREF="http://www.newegg.com/app/Showimage.asp?style=album" target="_new">Here is another from Enlight.</A> I have one of these running my XP2000+. It has 18A on the 12V line.


There are tons of others. The two big things you need to look for in a PSU are 1, that the company makes reliable equipment and 2, that the amperes are on the right lines for your setup. Don't just look at Watts(W).
