PSU recommendation

[ultflood]

Hi there-

Can anyone recommend a good ATX PSU for around $50 that will comply with a Compaq Presario 1750NX? It has a 300W PSU - do you think it can handle a PNY 7600GT or a GS?

Or new PSU? The computer has an Asus A8AE-LE mobo.

Thanks a lot!

Fortron to start with. You can do better but for the moment its OK.

Compaq, HP, Dell, etc. use funky voltages for their CPUs and mobos, you will fry the cpu and mobo if you change it to something not certified by the manufacturer.

Stop spreading FUD.

That isn't true with HP/Compaq/eMachines/Gateway, & i very much doubt it's the case for Dell.

Check the PSU out and make sure the voltages are fine.

Come back to us with the manufacturer and/or a picture of the label on the PSU.

Units manufactured for Dell/etc. are usually under rated... hence the reason a Dell PC can be running SLi with every bell/whistle imaginable on a 400W PSU and survive.

Hi OP, first post.

Go to Compaq's site and get a PSU part number. I sure won't do it for you.

If it's odd-ball size you maybe out of luck. If it's PS2 your lucky.

Look at PSUs here if it's oddly shaped http://www.power-on.com/index.html
Then Froogle for a better deal.

Actually Compaq's site does not have a part number for the PSU. Google didn't help either.

Any suggestions?
Thanks

Ummmm.... yes it is. All workstation HP, eMachines, etc have different (or funky as I like to call it) voltages and power communication between the motherboard and PSU. Most Dells I believe also.

Older Dell desktops had what looked like an ATX cable, but the voltages were different on some of the wires, resulting in toasted parts when trying to replace the Dell motherboard, or trying to use the PSU on a normal ATX motherboard. If anyone happens upon this thread trying to determine whether their Dell is one of these booby-trapped ones, check PC Power & Cooling's PSU configurator, the Dell-specific section.

For the Compaq, compare the ATX cable's wiring to a known-standard ATX power supply, look at the colors of the wires (which indicate their voltages). If they match, wire-for-wire, then consider that Fortron posted earlier. The Fortron has no negative-5-volt wire, but hopefully your Compaq is not going to need that in this day & age.

Update, found the specs: http://h10025.www1.hp.com/ewfrf/wc/docu...duct=1815877&lang=en&docname=c00496280

The motherboard spec shows it's using 24-pin ATX main plus a 4-pin ATX12V secondary power cable, so it looks like a normal Socket939 board to me.

Found PSU specs, phew:

5188-0129 (no manufacturer specified)

Tech person mentioned ATX-compatible PSU with 8Amps/100-127V input.

Any suggestions now?

Thanks very much

The Fortron AX450-PN that was mentioned above, that's a decent value and ought to power a 7600GT and an A64 without breaking a sweat.

 

[ultflood]

Thanks Mech, you've been very helpful-

Only I noticed that the FSB is 8.5A input? Does that matter?

Thanks again

It should be just fine, unless your house's wiring can't handle an 8.5-amp draw If your power outlet can run a hair dryer, you're definitely home free Welcome to the Forums BTW, enjoy your new video card!

I have this PSU in my system. Opteron 146@2.4, 2 gig OCZ platinum ram, dvd burner, eVGA 7600 GT, 1.44 floppy, sound card, 1 PATA hard disk and no problems...

Very nice psu for the money IMHO.

How's the noise level on the Fortron? Pretty quiet?

Hehe, I guess my question was this: if Compaq said that the pc requires an 8A input (110V) for PSU, does that mean at least 8A? Or exactly 8A? Sorry I don't know much about this kind of thing.

Thanks

Fortron or Sparkle since they are the same company. With Sparkle, you get more amps on the rails for about the same price as a Fortron with a 50W higher rating (compare 400W Sparkle vs 450W Fortron)

I think it means they don't know what the heck they're talking about. Why would it matter how much power it draws from the 110-volt wall outlet?

~ It is not logical, Captain.

If they had said something like "well, you need an ATX2.0 unit with at least 15 amps on each of its two 12-volt rails, plus a PCI-Express power plug for the video card and at least one SATA plug for your hard disk drive," then that might give us some excuse to think that they have a clue, but as it is, I'd just order up that Fortron, compare the plug's wiring colors to the old 300W to be absolutely sure they're wired the same, and then plunk it in there.

 

[alpha88]

I think that you should be able to upgrade your video card to a 7600GT without replacing your powersupply (unless you've been overclocking as well).

The 7600GT doeesn't use that much power, and I can't imagine the Presario to be so close to the edge that the increase would be too much.

 

[Arcanedeath]

You should be able to toss a 7600gt class card into your system w/ the stock PSU

Thanks all

OMG!!! Most ATX boards are ATX. Some Compaq's and Dell's are ATX but does not have an ATX pinout on the 20-pin connector, I do admit. But these are few and far between and never are they Asus motherboards.

 

[ultflood]

So I talked to Compaq and they say that

100-127v/8A input is recommended because that's what the stock is

and

400W max is recommended because they haven't tried anything more...

But the mobo ASUS A8AE-LE won't mind, right?

Thanks
