Hello. I am in the process of replacing my old dell xpx 435t psu with the corsair 650hw.
Is there any guides for doing this? as I'm such a noob with all the cables and don't want to do any mistakes, I'm afraid of forgetting where everything goes after I have replaced the psuMy system has been pretty expensive and I don't want to **** it all up
Here's a guide for a start,
How To Replace Your Power Supply | Hardware Secrets
Next a supply of twist ties and tags comes in handy. As you pull each connection write on the tag where it came from and put on the cable with the twist tie. then after the new power supply is installed, use the tags as a reference and make all the connections, removing each tab as you go to avoid confusion.
Little tip. Keep the current PSU in and as you take connections out, replace them with the new PSU connections if you are not as tech-savvy. Thus you dont get confused and forgot a connection.
lol @ Stormy13 I never thought of useing tags lol i actually just put everything where it had to go i dunno im more of a hands on guy but that is a great idea
awesome tip though
Thanks for help guys. I know a guy which works with computers, I think i will ask him to do it to be safe.
There is no problem with replacing the psu in a dell system right?
I'm also putting in my new sapphire radeon 5970 HD, I got to take my old nvidia gtx 260 out too. Really think I would need some help.
Just wire it back to the way it was...
There are only a few connection 'types' you need to worry about...
20 pin power (with optional 4 pin)
4 pin power to mobo
4 pin molex power (ata dvd's, ata HD's...some fans)
'Flat' 4 pin floppy power
SATA power
PCI-e 6 pin/2pin power.
If you are familiar with all the the above? Dont bother 'labeling' things.
Just replace the PS then start running the wires that are the most optimal in relationship to where the devices are located within the case.
It REALLY IS a piece of cake.
Good luck!
For the record...when you have 7 machine spinning 24x7, on average, I replace 2 P/S a year.
Matter 'o fact, just replaced a P/S yesterday!!!
It was a crappy 340W I had used when I rebuilt the TV PC last year. Replaced it with an 500W ultra.
Okey. Thanks for all your help. Just to say it was too much for me, and when I finally got the stupid metal cabinet of the psu open and saw the custom dell psu i just "no way!"
So I'm changing both the card and the psu and going back to one of the newest nvidia cards instead. Well ati it was fun while it lasted :/ next time I'm gonna build my system or atleast get someone (a neutral company) to build it for me.
Your system is a Studio XPS 435MT?
I think that the PSU in that machine is an industry standard type. (You want the sort with an 8 pin +12V connector for the CPU power, rather than 4.) A little Googling confirmed that.
It's held in by the standard 4 screws.
If you think that you're up to building a new system, swapping in a better PSU should be no great challenge. The service manual at support.dell.com would help. (It even shows you how to get the side of the case off.)
Maybe you have a chum who is less intimidated by the guts of a PC?
Im not intimidated. I just don't want to make any mistakes in the cabling.
I have replaced the most of computer parts, the PSU is one of the few I haven't.
I don't want to screw up my system over this, then it's better to go a safer way.
