Welcome to bleepingcomputer!

I can't really tell from the picture, and it doesn't have any info on the power supply itself. I would suggest opening up the case and seeing how many pins are on the main power connector. It should be 20 or 24 white pins and looks like this: http://www.hardwarezone.com/img/data/artic...tx_power_co.jpg.

The power supply should also have a 4 pin cpu connector going into the motherboard like this http://www.techaddicts.net/reviews/gp550/gp550.10.jpg .

If you have these two connectors going from the power supply to the motherbaord, then a standard atx power supply should work. It may not fit properly, but you could probably make it fit.

it says ATX on the label. it's 24 but the psu is only connected to the mother board with 20 because the psu didnt come with the +4 for it and when i get a new psu should i connect the +4?

you will need an ATX power supply with a 20+4 pin (or 24 pin connector) plus a 4 pin CPU power, and depending on the video card your upgrading to you may need a 6 pin PCI_E connector. and even 400s kinda weak in todays market, a good 5-600 watt one might do ya better down the road. This OCZ one would make an excellent choice http://www.newegg.com/Product/Product.aspx...N82E16817341010 and for a slightly cheaper PSU that isnt quite as powerful or efficient but should still do everything you need it to this coolermaster http://www.newegg.com/Product/Product.aspx...N82E16817171038 one should do. Between the two, I would go with the OCZ but if your on a tight budget the coolermaster would work.

as long as it's under $100.00 and has alot of positive comments saying it doesn't fail after a couple of weeks then its all good

thats not totally true, it also depends on the use. I had an echo star 600 watt PSU, that had a lot of good reviews, but it was only designed for generic computer uses, not for high end gaming uses, it only had 1 12v rail running at 18 amps. It had excellent reviews, but safe to say when I threw in my 3870 x2 video card which all the instructions said required a 500 watt minimum PSU, it ended up frying the PSU in 3 days time. there is more to a good PSU then the wattage, and the reviews, though you definetly want a high percentage of good reviews, you need to watch for the wattage, and output amperage, and overall quality of the PSU.

No. Try not. Do... or do not. There is no try.

Take your pick, if you can live with rebates they are a very good deal.

Many HP/Compaq cases have one of the PSU mounting screws in a different place, or a metal tab that gets in the way of fitting a standard PSU. Tin snips or a Dremel can be your friend.
