Power Supply

I have and HP Pavilion a1650y series
Pentium 4 3.06GHz
2 GB DDR2-533MHz dual channel SDRAM
128MB NVIDIA GeForce 7300LE, w/ TurboCache (but planning on upgrading)

I will need a new power supply for the new graphics card I want to get
http://www.newegg.com/Product/Product.asp?Item=N82E16814150202
A GeForce 7900GS. Can I buy any PSU that fits that case and has the right connections, or do HP motherboard require specific PSUs.

Yup . . see replacement PSUs at link below ATX 12V

In reply to: Power Supply

It gives you the specs...dimensions, connectors, pin-outs and of course you'll need a much more robust PSU for your system...looks like a MINIMUM of 400W with 27A and you definitely need more than the minimum.
Choose carefully . . it's the heart of your system.

Now I'm confused since I have an a1650y I guess I have a HP p/n 5188-2625 and it says to replace it with a ATX12V-HP300BT-R
(link http://www.power-on.com/atx12vhp300btr.html) But this unit only has 300 watts. What am I missing?

Recheck again and follow through

In reply to: Ummm

If you revisit that webpage, check the specs of the "size measurements" and it looks to me as a basic ATX12V PSU. Then go to NewEgg and check the specs of the PSU you wanted or others and then compare size, then the power wattage, etc.. and find a 400W or better PSU that of course is the proper size.

This is the replacement unit and specs for your existing

In reply to: Ummm

system...it shows the physical size of the PSU, the different connectors..24 pin MB PSU connector and that it's a generic PSU. So the trick is finding a replacement PSU that's physically the same size but gives you the wattage and 12V AMPs to run your system including the new 7900GS video card.

I couldn't locate the XFX PSU requirements again but did find info on the BFG version of the card..see below. It shows a min PSU requirement of 350W and 22A. Personally I never never recommend buying the minimum. Again...I would look at 450-550W with a minimum and 25AMPs. Ultimately it's your call but whatever you do...don't
skimp on this critical component.

Here's some of the specs PSU watts and AMP for the BFG 7900GS GPU.

VAPCMD when you say at least 27 amps, does that mean the out put on each of the 12V need 24A?

300 Watts is minimal requirement

In reply to: Power Supply
