Our Pavillions a610n won't power on. This has happened before and we were able to disconnect and then reconnect the power supply to get it running. I'm assuming we need to replace the power supply......


Bad PSU day: 13 year old PC, retired, at HP and legacy status.

the A series desktops are very very old, and no support now.
the problem is there is not just one PSU now,
they evolved the PSU ATX sec as things changed. in time.
any watts over 400 is ok, unless gaming and power sucking new, GPU card is added.
point 2: ive no idea at what is inside that case now
upgrades, add-in PCI slot cards, ext.? how may HDD.
or what. its old things change,
so Ill pretend nothing changed, ok/ and tell you what it has
and what to buy, buy more watts , as the bigger watt PSU is higher priced and more quality, built in. a $15 PSU is junk class.
Q1: is the power jack 20 or 24 pins.?
Q2 does it have IDE drives or SATA.
Q3 do you really use that floppy? and its silly PSU power cable.?
more watts never will hurt you or it.

ever go here.? newegg, nice , choices on left.

and see the left side under TYPE.
that must match your needs,
  • first I buy quality,(and brand names) never china nonames.
  • then large fan
  • then type,
  • More watts gains you quality line 1 above. most times.
in that order. what matters to you , I could never guess
the large fan is quiet, if you like less noise,. bingo.
this?
Lucky you no relic IDE Drives, inside, more pain.

Is your phenom Phenom-X3-8450e or AMD-Phenom-X3-8450 ?
8450e is suported by that mobo but in the asus suport page you wont find 8450.
Check here https://www.asus.com/Motherboards/M4A785M/HelpDesk_CPU/
8450e runs on 65w and 8450 runs on 95w.
Does your mobo run with your old CPU?

It actually depends what you are all hooking up to it. In my experience, if you just have a hard drive, cd/dvd drive and thats it, a 250 would power it up. I would recommend a decent 300-400 watt PSU if you plan on putting anything more than a hard drive and dvd drive in it. But for testing purposes, a 250 watt should do the job. I don't know about a motherboards minimum requirements though, depends on the CPU, Memory, # of fans etc. that you have.

NVidia GeForce 9300 265MB with a 250 watt PSU


GeForce 9300GE is the video card
GeForce 9300 is the motherboard

Also 250 Watt would not be sufficient for most new video cards. Most need a 450+ for requirements.

Giga Ethernet is short for Gigabyte Ethernet which allows for more speed if you have a higher speed internet service

Comp not firing up


Something may be shorting out the board. Try taking the motherboard out and turning it on without the case. Just put the motherboard and power supply on a non-static surface. A box works well. Then use a flathead screw driver to temporary "jump" the 2 power switch pins for the front panel connection (as you wont be turning it on while inside the case).

If that doesnt work, then replace power supply. You could also take one out of another working computer just to test.

Upgrading power supply


The next time you get a PSU. Tell them what you have. Apparently you got one that is not compatible with your compaq.The power (500 wattage) will work with your MB.
Get an OEM PSU from Compaq(HP).
