I have this psu that currently came with my computer.
i contacted hp to do this the easy way but i needed to join their warranty program to get specs and tech support to buy their upgraded psu. I did get to find out that this cpu has only been tested with a 400 watt tested psu. So i dont want to try anything over 400? Okay i have done some searchin and found these in the order i like them.

this one has 8 peripherals, so i can actually come straight out of psu to my new video card, instead of jumping off my dvd/cd power or my samsung hard drive. which i do now.


im just not sure as far as connectors go if these or atleast my favorite choice has the same connectors as my current psu? Will the 1st upgrade link (the black one, at tigers direct) psu have the same connectors as my current, a side from 8 periphrials? which is better for me, then i can hook my supplementary power from my video card(agp) straight to psu? As far as dimensions, i can figure that one out thank god.

That's a Bestec power supply; even the super-cheap PSUs are better than those. Replace it before it packs up altogether.

PSU wise, you can have it as many watts as you want; the system will draw what it needs. Even if you put a 650w PSU in, the system won't necessarily use 650w, in fact if its happy on 250w now you've got plenty of leeway.

Your affordablesurplus.com link doesn't work. The TigerDirect link does and has more power links on it than anything you'll buy from HP.

this one is for sure the exact upgraded match as far as connecters go, as yo can see it even says it's an upgrade from my current one. BUT there are only 4 molex connecters i wanted at least one more that runs a lone from my psu to power my graphic agp card? I just need to match my current connecters but add at least one more molex/peripheral
connecters. Also i need at least 18-20 amps on a 12 volt rail. Are two 12 volt rails better? Also i hear Antec is the better quality psu? Please give me some recomendations?------------------------i need help please---------------- I would rather not get so high of wattage but keep up in the amps, maybe spend between 40 to 70 bucks(whatever). I can say this..I have my Bestec 250watts with only 14amps on 12volt rail and just recently had a 7600GS running the game enemy territory. And was pleased but thought i could do better. Now i have upgraded to 7600GT cuz, i was told it doesnt use much more juice than my 1st upgrade 7600GS but then i was told to play it safe, and to wait to install it, till after i get this psu. I do know this...I have (1) 20 pin ATX connecter, (1) ATX12v connecter (4) peripheral power conecter and (2)floppy drive connecters. Now to lessen the confusion, i just need one with those connecters but i would like an extra peripheral for my agp card(7600GT). So instead of 4peripherals i need 5 or more. Are these good options for me. Matching up to my current psu?
