Almost novice at this even though I have replaced the graphics card. How would I know if this is compatible for my computer? If I am understanding the codes it is currently a 400W & I want to also add a mem upgrade shortly. My computer is a Compaq Presario SR1010V with Intel Celeron proc 2.6 ghz 256 ram 40g HD Intel Extreme Graphics Thank You!!

  • A. You must open your tower and see what style power supply you have in there currently. There will be a model number listed on the side of the power supply. Do an internet search and you can find out what form factor yours is. This power supply is an ATX12V form factor.

  • A. According to the COmpaq website, the pc you mention has this: --Three PCI slots (two available, one is occupied by the modem)-- that means you do not have an AGP or a PCI-e video port but a rather old standard PCI slot. The Video ability is built on to your motherboard that cannot be upgraded. Though there are some, PCI (not PCI-e) cards out there, the search and $$$ you will spend for one may not be worth it at all.

This product does what it was intended to do, but determining that was a big annoyance on this website. I had to visit three other sites to get enough information about this product due to the simple lack of any real data about all of the power supplies that are on this site.

the 12 and 5 volts measured at 13.5 and 4.5 volts. Measured the 24 pin main board connections and it measured different voltage ratings than what they are supposed to be by over .5 to 1.5 volts. I wont be supprised if this killed my motherboard.

Customer has been confirmed to have purchased the item from Walmart.

I installed mine and it has been running for almost two weeks. It is quieter than my old supply and seems to not get as hot with the big fan that it has.

Has a large quiet fan for good air flow. 650watts for sufficient power. Many plugs for most configurations. I am very pleased with this purchase.
