Dimension 8400 with Corsair 620w?


Rellik101

Recommended Posts

Hello, I have a few questions that I would like to get help with. I literally have a Corsair HX 620w sitting behind me as I am typing this.

 

I already know that it does not fit in the back because the PSU's cable entry and switch do not match up with my case. I will need to modify the back of it if I am to use this power supply.

 

Basically, my question is this. Will this power supply fry my motherboard?

 

My Specs -

 

Dimension 8400

Pentium 4 3.4 Ghz

3 Gig Ram

XFX 8800GT (When I install it, also sitting behind me with my power supply)

Hard drive - ST3160023AS (160 GB, 7200 RPM, SATA)

Optical Drive - PHILIPS DVD+-RW DVD8631 (DVD+R9:2.4x, DVD+RW:16x/4x, DVD-RW:8x/4x, DVD-ROM:16x, CD:40

Sound Card - Creative SB Audigy 2 ZS

 

Basically, I'm not sure what you guys need to know, so I just threw everything down on there. If there are any questions about my specs or anything, please ask, because I am not really that knowledgeable in computer hardware.

 

Thank you for your time.

Also, since I may have to return this one, does anybody have recommendations for a power supply sufficient enough to hold my computer stable w/ the 8800 GT that is also Dell compatible? I'd like to stay away from the ultra expensive items, if possible. I have a stock 350w Dell power supply also, but, from what I know, it will not be stable.

Correct. You will need to dremel out the back of the chassis to get the Corsair to fit properly. If you want a direct fit then I would recommend a PCP&C Silencer 470.

No, the Corsair is compatible.

No, the Corsair is compatible.
Ok, what evidence do you have to prove this? Did a quick search last night on Dell's site, didn't find PSU specs, or even a PSU in their website (IIRC they only sell them through their replacement parts sales dept via phone). Granted, it was 2 AM, so I may have missed something.

This is all Dell recommends for an "upgrade" to my system. http://accessories.us.dell.com/sna/products/Power/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=F4284&mfgpid=166540&chassisid=8224#Overview

 

I really wanted to avoid calling Dell and dealing with all the holds and people with crazy accents, but I guess I will do that soon. Any other input is appreciated.

If it helps I service pc's for a living, and I've installed after market psu's in the 8400 before. ;):

The Dimension 8400 uses a standard ATX power supply with a 24-pin main ATX connector and a 4-pin 12V connector for your CPU.

So this means it's good to go? Awesome. Thanks for the help.

 

Also, while I'm typing here, I am pretty much upgrading my computer this Christmas. Hence the 8800gt gfx card, 3 gig ram on XP Pro, and that power supply. I also have a 3.4 Ghz pentium 4 processor. Will this processor bottleneck my upgrades or will I be fine for the time being? I'm pretty low on cash now so I'd have to save up for a new processor. Planning to play games such as - Call of Duty 4, Crysis, Bioshock, Company of Heroes.

If your getting a new PC, buying a P4 is kinda pointless. Especially when you are paying around $400-500 for your GTX. You can get a Core 2 Duo E6600 for around $200-250 I think it is now.

I am just upgrading a PC that I bought 2-3 years ago. The Pentium 4 3.4 is just what came with it - I have yet to upgrade it. I'll keep that processor in mind though, thanks.
