My soon-to-be-rig:
Intel C2D Q6600
GA-P35C-DS3R
8800GTS 320MB
WD Raptor 74GB x 2 (RAID0)
Kingmax 2GB PC6400 Ram
DVD-+RW

How much wattage should I need? Can you pick a power supply for me? I'm on a strict budget, so I need to save every penny. Thanks all!

Some choices would be

Silverstone Olympia 650W

Silverstone Stride 600W (if you want modular cabling)

Corsair HX620W (also modular)

All three are great power supplies, if price is the most important issue get the Strider, if you feel you want a little extra power the Corsair is also modular but delivers 50A instead of 42A. The Olympia delivers the most power and is cheaper than the Corsair, but its not modular. Any of the three will power you system perfectly fine.


but because i have to say this is if your on a budget don't bother with a RAID0 setup with 74GB raptors. The extra performance you get won't be nearly worth the money. If your dead set on RAID0 get two Seagate 250GB or something a little smaller. If your dead set on a raptor drive get one 74GB Raptor and one Seagte 250GB. Either way you'll save quite a bit of money and have nearly the same performance.

I will also offer the XClio 600W being higher up the list at johnnyguru's website.

Your real life wattage would probably be under 400 watts. My E6600 is less powerful than the Q6600 but with four harddrives and the 8800GTS I am only measuring 220 watts AC under load. It's not bad to have a lot more power than you use, but you said you are on a budget, so that's something to consider.

I'm pretty much in the same boat (Q6600, 8800 Gts). I just can't figure out how big of power supply to get.

600W
650W
or even 700W

Is 600 W enough for a Q6600 and GTS no SLI and maybe some minor overclock?

I would buy an 650 watt psu like seasonic psu.

My Seasonic S12 500 with 33 amps on the 12v rails can easily handle such a PC.

Here's a hypothetical build assuming each and every component is being stressed at 100%:

Q6600....................................................87W
EVGA 8800GTS 320MB KO......................118W
6 Hard Drives @ 14w each.......................84W
1 DVD Burner................................ .........14W
3 120mm Fans full speed.........................18W

Total Estimate 12v max power draw........323W
Total Estimate 12v max amp draw............27A

All other components draws power from 3.3v & 5v rails.

Right now I was thinking of a 600 W? But it looks like I should go with 650?

Whould it change much if I went with a HD2900XT?
Does this add that much more Wattage then a 8800 gts?

Thanks

Like i said any of these power supplies

Silverstone Olympia 650W

Silverstone Strider 600W (if you want modular cabling)

Corsair HX620W (also modular)

will be great for your setup. They will handle any single graphic card slot to date.


Take your pick on your price and/or if you want modular cableing.

The question is not wattage, but how many amps can be delivered at 12v. This is a function of the efficiency of the PSU and how many watts go to the 12v side vs. the rest. Nvidia recommends 26A on the 12v rails for a 8800gts. Check out this psu reference list for a list of quality units: http://forumz.tomshardware.com/hardware/modules.php?nam... Look for a psu that has at least 26amps, and that does not have an asterisk in front which indicates that it is not suitable for a Quad core cpu. About the lowest priced unit I see on the list is an Antec NeoHe 430w for $70. You can get this psu included in an Antec P150 case for $139 delivered. Otherwise, I would look at a Seasonic unit, if for no other reason that they make several of the psu's sold under other brand names.
On the Hard drive, consider getting a single 150gb raptor. It will cost you $170 vs. $270 for the two 74gb units. The performance will actually be better. Go to www.storagereview.com for a thorough tutorial on raid-0 and some benchmarks that are representative of what a single user in a desktop environment might expect. Synthetic benchmarks like hdtach are accurate enough, but are misleading as a predictor of value to you. On other benchmarks, look at the values where the queue level is 1, or 2 at most.

He would be fine with the cheaper 520 (40A) corsair.

Much agreed ;)

In fact he could even stick in an 8800GTX with the HX-520, but not SLIed.
