PSU Wattage..

Recommended Posts

Well, i am finally getting around to building a new system.

Anyways, i have ordered a Extreme Quad-Core (2.66) , 3 Hard Drives (Going to expand to 6 eventually).

a Crossfire able board, and a 2900XT. (and i will be adding another when my financial situation allows)

 

What wattage should i be looking for?

I did try a calculator online, but none of the sites are current enough, and are missing alot of hardware.

Thx, Pork.

I have a similar setup here...Q6700, 3 hard drives, dual ATI XTX 1950 boards (cross fire), 2 DVD drives and

8 Gig of ram. With my Quad OC to over 3.8 Ghz my ups says I'm using about 680 watts, but that also

includes A cpu cooler and 24 inch monitor...I have a1000 watts PS

and all my voltages are very stable at full load and OC.

660 watts load http://www.pcpitstop.com/techexpress.asp?id=6941HW77EKWS4ZFW

(8 Gig pc800 )

649 watts load http://www.pcpitstop.com/techexpress.asp?id=7VX1HW77EKWS38FW (I Gig pc1100)

 

Hope this helps :)

Go for the 1100w Tagan, or if you can stretch to it the one in my Sig, but even if you wont use the whole of it yet it will give you some updatability later, if you buy what you need to suit you now, come upgrade time you will need too upgrade the PSU again, so do it right first time and save money long term IMHO.

as much as i love my tagan i have to disagree ....

 

of the 3 previously mentioned PSU's only the Silverstone 1000w has the needed dual 8 pin PCI-e connectors that the 2900XT needs to take full advantage of its potential

 

something you're going to want to look for in a PSU if going to run 2900XT cards

 

and By the way we would love to welcome you to join team PCpitstop in Kicking TRP's Butt again this year its going to be a blast :lol:

I hate to be invisible :pullhair: ...I'm using the dual 8 pin PCI-e and it's not silverstone... :nono:

Ah I didn't know that card had special requirements, I was basing my suggestion on knowing the Tagan to be right up there with the best ATM, but the other one I suggested in my Sig from PC Power & Cooling has 2x12v with 8 pins, but only 6 pin PCI-e plugs so I don't know how that would differ, first I've heard of 8 pin PCI-e ones, how do these compare to the 8800's then ?

the 12v 8 pin connectors are MoBo power connectors and may be different pin outs and or connector may not fit

 

the 2900XT is capable of using 2 6 pin PCI-e connectors but would benefit from using a 6 pin PCI-e and a 8 pin PCI-e connector

 

i wouldnt try the MoBo connectors ...............

 

i'm sure its just a matter of time before some one makes a Molex adapter for the remaining pins

Yeah I dare say adaptors will be out at some point like you say, but I'll have to keep an eye out for these types of cards now, I think it's OCZ that are sposed to be brining out a 2kw PSU by around Autumn this year, soon the PSU will be bigger than the PC lol.

Once you figure out what you think you need, add 25% to that and that's what you should get. A PSU that doesn't have to work very hard is going to run a lot cooler and will be much more reliable that one that's always running at or near capacity

Yep, due out this Autumn apparently, it's OCZ that announced they are doing this, it maybe a month back now.

a 700w PSU wont support quad core, dx 10 graphics, single hard drive, and 2 gigs of ram?

A good 700w PSU should support that.

I like this one a bit pricey but 1200w, 1400w peak.
