Hi,

Currently I have a Cooler Master PSU 350W with the spec at my sig. If I want to replace some of them with C2D 6650 (coming up next month), Gigabyte-P35-DQ6, and a pair of Corsair TWIN2X1024A-6400C4 (1gb), can I use the same PSU?

More about : 350w spec

You could, but coolermaster isnt exactly known for making quality power supplies. I wouldnt risk all the new hardware on a mediocre PSU.

I'd need voltage/amperage ratings on the PSU to tell you for sure if you could or not, but gut feeling is I wouldn't use such a small PSU unless you are running integrated graphics.

The Gigabyte-P35-DQ6 motherboard does not have integrated graphics.
It has dual PCIe x16 slots, and is more of an enthusiast’s board.


This is very true, I was just giving an idea of when a 350w PSU would be acceptable. :wink:

How much power do you recommend? A friend told me to get 500 watt...

Also, since I'm new with this PSU stuff: does every PSU has common dimension, so it would fit in every case?

Video card? In his sig it says he's running a 7600gt, a fairly low power card. With the upgrades his system would still consume about the same amount of power.

I'm not sure why I'm defending the opinion that he can use his old psu, since it only has the bare minimum of power required to run the that pc. That, along with the low quality of the unit itself, using it would just be asking for trouble.

Get a new psu guy.

Generically yes, all PSU's have the same dimensions. The only ones that don't are your really big ones, usually 1000w kind.

The question is what kind of video card do you plan on running? are you going to stay in the mid range (cards similar to the 7600GT) or will you be going higher end like 8800GTS/GTX?

Honestly, a quality 400w (450w preferably) will be plenty for a mid range setup (overclocking withstanding).

Higher end will require more along the lines of 600w+

The motherboard the OP wants to get is comparable to a 680i board or ASUS striker extreme. It also will cost >$300 US.
Why buy that type of MoBo to put low end GFX cards in?
High end componets and cheap PSUs do not mix well.
I wouldn't put anything less than a high quality 600w+ PSU with that MoBo.

OP, why do you want this motherboard?

I'd stick with 7600GT, since it serves me well for the past year ^_^

Err, honestly, I never overclock before. All I want is to build a mid-high end system (also my first time doing it myself), with the new chipset and all.

Also, maybe I'll only do mild overclocking...

A good 600W would definitely run it. But why would you want to waste the extra money on a good 600W PSU, when a quality 430W will work? To take it a step further, I agree with Apt403 that his current PSU would power the rig after his upgrades. I don't remember the numbers, but I think the 6650 will actually draw less power than the Pentium D in his rig. I would get a better quality PSU for the simple fact that I believe it is probably the most important part in the case. Suggesting a 600W PSU for his setup simply doesn't make a lot of sense. It would make sense if he stated that he was going to upgrade to a power hungry GPU, but he didn't. JMHO

1: It is a dual PCIe X16 crossfire motherboard.
2: The MoBo is built to OC
Why waste money on this MoBo when you can get the GA 965p DS3 for 1/3 of the price which will also run 1333mhz FSB processors. The money saved could be used to upgrade GFX,PSU, CPU, and or memory.
You don't buy a $300+ Motherbord to put subpar componets on.
If the build is for future upgradability the first place to start is a Quality PSU that is able to run dual GFX cards and OC.

or, maybe I can buy its "younger brothers", the P35-DS3P or P35-DS4, and put the extra money to buy Thermaltake TR2-500W or TR2-550W PSU instead...

comment?

That would suit your needs better.

I realize what the mobo is capable of doing. If I were him, then I would buy a less expensive mobo and put the extra cash towards a GPU and PSU upgrade if his priority is gaming. The reality is that I am not him so I based my recommendation on input he provided.

If he has other upgrades that he intends to make, then he should state that when requesting our input. For all we know, he may have a source to get that mobo for significantly less than $300 or free and that is why he will be using it. As it stands, the system components that he stated do not need a quality 600W. It can be easily done with a less expensive, good quality PSU rated between 400-450W or possibly done with his current PSU. As previously stated, I would still recommend a better PSU. You need to base recommendations on the OP's stated intentions, not speculation on what he might do with a particular component.

Like I stated before, You don't buy a $300+ Motherbord to put subpar components on.
The OP either didn't realize what the motherboard was designed for, or wanted to have a crossfire upgrade path with the new motherboard (why else would you buy one?). A good quality PSU is needed anyway, with the P35 DQ6 600w+ would support Crossfire GFX, For the P35 DS3 500W+ would be sufficient.

Here are two good PSUs

620 Watt

Well, those stuffs (mobo and CPU) are still in consideration, since maybe I'll buy them at July.

I really appreciate your comments and suggestions, you guys have been helpful :)

Yes, it works fine with my current rig.

Just because a PSU is 450w doesn't make it subpar. A 450w PSU would be more than adequate for this application and gives some breathing room for future use.

680i boards are SLI, not CF. Just because you buy a CF or SLI board doesn't mean you intend to use it. I have had 2 CF boards and 1 SLI boards and don't use either dual GPU solutions because they aren't cost effective.

Quality means stable power not overkill in amount of power. 400-450w is fine.

Again overkill.

This is more reasonable: 400w

Reviews of the P35 DQ6 compare it to a 680i chipset.

Why pay extra for fetures you will not use? The money saved could be used elsewhere on the build.

So, the 600W PSU in your sig is not overkill?

Nope. When I originally bought the PSU I was running 7900 GTX's with an OC'd CPU which when spec'd on Extreme PSU Calculator the system pulls 40.1a and the PSU puts out 43a, so no its not overkill. It is appropriate.

Good Try. 8)

You are right, the P35 is a better choice if you never intend to go SLI/CF. :D

so,uh, it's now safe to assume that I can use my current PSU 350 watt) to run C2D?

I'm not planning for future upgrade though... I'll consider my current rig (with planned upgrades) will run for at least 6-9 years from now :wink:
May 19, 2007 1:48:09 AM

Yes, just don't expect to much headroom if you OC. :wink:
May 19, 2007 4:39:21 AM

again, thanks to all of you :D
