A few crashes and now a burning electrical smell has finally told me that my psu on my HP m8400f needs replacing. I live in the middle of nowhere, so need to order it. Point me to what I need? :)

I might sound stupid, but you mean if I don't play video games ( I don't) this should good enough? Just want to make sure before I order one

The 430 doesn't have ATX 4pin, it has EPS. From the newegg link you sent:

Connectors:
1 x Main connector (20+4Pin)
1 x 8 Pin EPS 12V
1 x PCI-E
4 x SATA
3 x Peripheral
1 x Floppy

I originally looked up the 430 on newegg but it doesn't list 4 pin ATX, only EPS. Thus the 500W recommendation. It's unfortunately more expensive but has the right plug. I double checked on Corsairs site and the 430 doesn't have 4pin.

yes it does

both corsair states it has an ATX power connector (4-pin)
http://www.corsair.com/power-supply-units/builder-serie...

as do review sites like kit guru
CPU 4+4 pin x1 (620mm)

where did you check on corsair's web site? because it is clear as day on tech specs

ATX Connector 1 - aka 4-pin CPU connector
EPS Connector 1 - aka 8-pin CPU connector

in actuality it's a 4+4 connector that can work in either mobo, same as the 500w and 600w version

Not solved!
I'm writing on my little iPod :(  hard to read all the specs on the two.
So the cheaper one will be fine?

yes

here are two more reviews stating as such

Motherboard Power Connectors: One 20/24-pin connector and two ATX12 V connectors that together form an EPS12V connector


http://www.hardwaresecrets.com/article/Corsair-CX430-V2...

1 - 4+4-pin ATX12V/EPS12V (600mm)

http://www.jonnyguru.com/modules.php?name=NDReviews&op=...

so you have three reviews and the official web site all saying it has a 4+4 connector

And now I can't seem to hook the old one back up properly to print a return label. Can someone point me in the direction of a diagram or something?? Am I missing something here. I was told the 430 would fit but it doesn't

A little square one with 4 connectors.
The 430 doesn't have it.
How do you 'unsolve' a question?

I assume you are talking about the CPU connector that plugs into the motherboard (bottom left of the CPU socket in the pic below)



the PSU has the following connector called a 4+4 and looks as such



take the connector from both sides and give it a small twist. it will snap into two 4-pin connectors. don't worry it's made that way and can be snapped together. insert the the 4-pin into your CPU power port on the mobo.

Crap! I got an 'Error, system has failed' I want to cry. Did I just kill my computer??
I split the plug. Figured i was ok then, but i'm fuzzy on how many connections the old one was using. Can someone point me in the direction of a diagram to show me what I have to plug in, because I was stupid and didn't write down what connects to where and I'm not a big computer person who is friendly with their motherboard. Ie- how many coonection am I using and where.
Blarg!

connects to your 24 pin port on the far right side of the mobo above




both connect to a video card, you don't have one so no need to worry about it



SATA power connectors connect to your hard drive and optical drive



molex connectors connect to older hard drives & optical drives. look on the back of the HDD or optical drive so see if it needs SATA or molex.



connects to your 4-pin CPU power port



connects to your floppy drive

that is your 4 - pin CPU power connector. one of the 4-pins (from your 8-pin) should click right in there with no problem.

The 1st one-done
2nd- video card - I have one - where do I connect?
3rd- there are about 4 connections that look the same- does it matter which one?
4th-not sure what you mean
5th- like #3, there are a few that look like that. Does it matter which one?
And again, I really appreciate this help. I need my computer back!
