New psu

[Dragoon42]

I haven't upgraded in awhile and I'm planning on upgrading within the next month. I was shopping around for a new PSU and the case fans are at the top or bottom? I was thinking of getting an ocz modstream, or gamextreme. Anyways, I noticed the back it empty (which is a good thing for me since it would be right in front of the ac vent) but is the fan gonna blow the air down into my case or upwards?

I'm sure this PSU is gonna be too much, but my upgrade is going to be:

4400+
DFI SLI-DR
X1900XT
2 HDD
2 dvd-rw drives

Money really isn't an issue (either a $50 fortron or spend the extra $30-40 to get a used ocz). Any other suggestions on the PSU?

Minumum power requirements for the motherboard you selected are 480w.

Go to www.DFI-Street.com and check out what we all use.

Yee gods.

The fan faces downwards and it sucks air up and out the back of your case. You do NOT need 480W (no matter what DFI street tells you ), the $50 fortron should be fine, any 450W from a good brand would be more than enough.

Other points either think conroe if you've overclocking or go for a 4200X2 or 4600X2 if you're not.

So even if I have a 3200+, two sticks of Crucial 512MB and a single 6600 card, I need a 480W PSU?

I am going to overclock. I just managed to get a good deal on mobo+cpu+2gb ram. So i'm going with that. The guy hit 2.7 with a Typhoon, hoping to hit 2.7-3.0 with water. Only using a koolance but it's right in front of my ac vent, which helps 100000x

I view the powersupply as the most important part of the system.

I purchased a 520w OCZ Powerstream a long while back for $99, and it is still running strong and rock solid as the day I bought it, and it gives me scalability in my system because I can rely on it to provide clean power if I upgrade.

Have you ever seen those guys who spend $10,000 on the best subwoofers, amplifiers and speakers for a car audio system, but they fail to purchase a stronger charging system (alternator, etc)? Those guys are always running back to the shop for blown speakers and fried amps because the are ignoring the importance of clean power.

Starving electronics of needed power only causes them to fail quickly, or simply causes them to perform poorly.

I vote for a strong PSU out the gate in ANY case. That is one part that I never fail to overdo.

Excuse me, but I take some offense to that. As a contributing member of DFI-Street.com (1,800+ posts) I would like to forgive you for your ignorance. I guess your head is really that far up your ass. Go over to the Street and look at peoples problems. 70% of them are due to an underpowered PSU.

If I had a choice and the PSU fan was a 120 or larger mounted in the "top" of the PSU, I would want to have the fan toward the "top" of the case if there was at least an inch of space above the fan. Otherwise you have the case fan, the PSU fan and the CPU fan all fighting over the same air.

So true.

That's why TAC CPU vents that allow the CPU to suck cool air directly into the heatsink work so well. Cool air in the side, down the duct, right into the CPU heatsink, out the sides of the sink and then exhausted by the rear fan and/or PSU fan.

That's why I think those side panels with the big honkin' fan in them are so stupid. And why I get irritated when people replace their 80MM TAC vent ducts with 80MM fans (it doesn't help people!!!!) You're just bringing more air into the "area" for the rear fan and PSU fan to exhaust out. But is the CPU really getting more air?

Unless you have a Hoover on your CPU, the PSU and rear fan are going to rob air from the CPU. It's bad enough when your rear case fan robs air from the PSU!

It all works if everything is laid out properly. I'm no Intel zealot, but they got it right with their TAC chassis specs for ATX!

The TAC is an "I spit in your general direction" solution. Provides a short-circuit for air to the case fan and PSU fan - air that hasn't yet done any significant work in the cooling of the system (air; like water, electricity and students; takes the path of least resistance). I generally block them off. If I think that the CPU really needs extra cooling, I'll run a direct duct to the CPU fan - far less leakage for the other fans.

350W is enough for that rig if you aren't overclocking. This'll work.

I've got 25000+ posts here. Does that mean I'm a member that's contributed much, much more than you have? Not necessarily... hehe

I'm getting mixed signals from your post.

A TAC duct should be adjestable so the duct can be extended right to the top of the CPU fan. You "generally block them off" but if you "think the CPU needs extra cooling, you'll run a direct duct to the CPU fan." Umm.. How is that different than the TAC vent?

You're funny.

Crap PSU is different to underpowered PSU and both are different to boards that are crap in terms of compatability (more than redeemed by their overclocking ability). If you truely need a 480W PSU for a DFI board then i'll stop advising people to waste money on an inferior product

It is true my ego knows few bounds if any but i think i'm on the side of Truth, Justice if not nessisarily that Other Stuff in this case.

The TAC generally fits reasonably well only Intel. I rarely use or recommend Intel. The TAC on most cases is a loose fit even for Intel - plenty of slop for other fans to drag extraneous air through. If I use a duct, it mounts directly to the CPU fan with 4 screws like this one.

Ok. Now I understand you.

I typically use AMD too. But I find that the duct is rarely more than 1/8th of an inch off. I can still telescope the duct down close enough to the CPU fan where it's getting a heck of a lot more cool air then just blocking off the duct.
