Hi, I recently bought a Hp Pavilion a6532f and I want to change the power supply to a 430-450 watt power supply to power the Sparkle Nvidia GeForce 8600. The power requirement on the box says 300w but I want to be safe. I have contacted HP for assistance on what power supply would fit in the case, and they redirected me to several resellers, but they all only had the original 250w power supply. Can most power supplies fit in any case? or do they have to fit the dimensions of the original? Cases have latches that support the battery, and I am not sure what to get. If anyone has any idea on what I should get, or knows a lot about power supplies and can give me some information, it would be great. The case is similar to the HP Pavilion 6400. Price is not a big factor, but I would like something around $60 or under. Thanks =)

I would hold off on purchasing another PSU, with the minimum requirements being 300W, that 450W PSU should be more than adequate. If you do decide to purchase another, the PSU in that computer is a ATX form factor, this is a industry standard size. This means that you can purchase a PSU from most any supplier. Newegg has a good selection to choose from.

The maximum wattage that can be put into my computer is 450 watts. I found 2 power supplies that are quite similar in specs and price, but I'm not sure which one I should get.

If anyone has any recommendations on which one to get, maybe one is a better brand than the other, it would be very helpful. I am not very experienced, so i was wondering if ATX 2.2 is a standard size. Thanks for all your help.

I'd go with this one personally. It's a better product, in my opinion. :thumbsup:

I found a good review of the Cool Master RS-460-PMSR-A3 on hardwaresecrets.com. They can't pull 460 watts without it turning off as a safety, but my from what i've been told by HP, my computer can only support a maximum of 450 watts so I think this is a perfect PSU for me. Thanks. I really appreciate your help.

In order for that to fail you're talking about exceeding 36A @ 12VDC, I don't think you are going to get anywhere near that figure with what you have going now.

I'm not sure what they are smoking over at HP, but telling you that this computer "can not support" a PSU larger than 450W doesn't make any sense at all. It's a stand alone component, it doesn't need any support of any kind. You could put a 1KW PSU in there, and the rest of the components wouldn't even know it.

You don't have to worry about wattage, you need to be concerned about physical size. Break out the ruler and do some measurements. It will be a tight fit. You'll probably end up removing the front bezel and sliding you CD/DVD drives forward to sneak it in, then putting them back

I bought the Coolmaster 460 watt power supply and it is standard ATX so it should fit into my PC. It should arrive in one or two days. Thanks for your help. one more question though, if I were to attach another screen, I would just add all the wattage my PC is using and if there is enough power, I could attach it? Also, is there a simpler way to check how much power your PC is using?

The height,and width have to be standard to fit inside an ATX form-factor case. The depth is not a specification and it varies.

if I were to attach another screen, I would just add all the wattage my PC

The monitor does not draw power from the computer power supply

Disable it in the BIOS...before your system loads Windows.

Physically install the card...boot the system...go into BIOS, disable onboard video, save settings...exit BIOS.
