PSU Dilema

I own a HP Pavilion 7960 with a power supply unit that was struck by lightning. I flipped the voltage switch the other way (while the computer was unplugged) and left it for a minute in efforts to reset it. That didn't work, I also reset the connections on the motherboard and the switch from the actual power button on the tower. That also didn't work. So I'm almost certain tha the PSU itself is dead. When power is sent to it, the light on the back comes on for only a second. I've tried to find another PSU via HP's part site, but that didn't work. So I have a dead PSU that neads replacing. Please help. I'm not as computer savvy as I would like to be.
The PSU is manufactured by Delta Electronics.
Model: DPS-120AB-1
HP P/N: 0950-3994
S/N: FCD0052260796
Input: 100-127V ~ / 4.0A, 47-63Hz
200-240V ~ / 2.0A, 47-63Hz
Output: 124W MAX.

well first of all borrow another PSU and see if the rest of the system is not burned which is very likelly. (always use a surge protector).

unless the comp is very old with an AT power suply you should have a standard ATX (if its very new - not likely with 124W- it might be an ATX 2.0 24 pin).


Anyway if you're going to get a new power supply get something future proof just in case you'll buil sometime soon a custom comp (as you should)

get a 500-600W ATX 2.0 from a good brand like enermax or pc power and cooling. Even if you have a standard atx 20 pin all new 2.024 pins are backwards compatible either with an adaptor of they have the extra 4 pins removable

if you do have an AT power suply its time to upgrade the whole system.

Look at the back of your pc case, how many screws hold the psu to the case from the back, if it's 4, then its possibly ATX, also look at the power connectors going to the mobo, there should be a 24 pin for ATX, and a possible 4 pin for the processor.

Also, disconnect the HD, video card and other cards, and remove the ram and try to turn it on, if it still acts up, chances are its the PSU

well i have an update, the power supply is only available from HP at a staggering $184.00. This computer is older than i thought. Having never built my own computer and leaving for school tomorrow, that kind of lowers my options. Just plain towers with the only real requirement being at lest 512 MB memory are hard to come by, or maybe i'm not looking in the right places
please help/advise

thanks in advance,

You'll more than likely have to buy the PSU from HP to have it fit properly - their case designs are proprietary and so are the power supplies.

You can buy a PSU from someplace else and it'll still work, but fitment inside the case may or may not be an issue. ALL of the HP's I worked on when I used to do PC repair were proprietary case designs with goofy, custom-sized PSU's.

Nowadays though, you can get a cheap tower with 512mb for hardly more than $300 - just have to look around local computer shops or retail stores that have sales. You don't need bleeding edge technology to do school work.

500-600W power supply?! Neutrino are you mad?! All he needs at most is a quality 250W. You're out of your mind.

hmmm....before insulting me I would recomend properly reading my post in particularly this line:

anyback back to the question platic fork is correct, I was only thinking of the at/atx/atx2.0 standards rather than the fact that the shape of the PSU itself might be HP only crap.

Just for the heck of it, I ran a search. Didn't realize that was the same Delta that made the high-end fans I bought a while ago. Appears your PSU is in fact ATX (anything after 1998 should be anyway, honestly). Anyway, this might help:

A lot cheaper than going through HP. You can get a 200w for $55.
Delta DPS-120AB-1 PSU (http://www.beachcomputers.com/dps-120AB-1.htm)

Another brand that appears to be a direct replacement for the PSU you currently have. Says it's compatible on the product listing page. This one's $35.
Micro ATX-SS200V (200W SFX12V) (http://www.power-on.com/matx145.html)
Micro ATX-SS200V replaces Fortron/Source FSP180-50NIV, FSP150-50NI, FSP150-50CI, Ilssan ISP 120S, ISP 120SI, Bestec ATX-100-5, ATX-151, ATX-1523D, ATX-1523F, HIPRO HP-K1603A3, HP-K1507A3C, HP-K1363A3, Delta DPS-145PB-111, DPS-120AB A, DPS-120AB-1, and HeroIchi HEC-145FC.

i love you

Sorry, neutrino, but I gathered IIwhitexb0iII wasn't going to be building a dual PCI express setup with 8 hard disk setup thus requiring a 600W power supply. I think his intent was to fix his current HP computer. :rolleyes:

But what if he decides he wants to power his discombobulator and electric doorbell from it later?

i love you
That's why I enjoyed being a tech - I like to help people and I liked fixing PC's. :) That's also why CompUSA fired me. I kept telling people the better, cheaper way to do things that they can do on their own instead of pushing products they don't need. :p Going directly through HP is overpriced anyway. Glad I could help - keep us posted on how things work out.

I want a dual PCI-e and 8 hard drive setup. :D

I can understand Neutrino's reasoning though. Any current PSU should be backward compatible with just about anything really that's fairly recent and allows for future expandibility should he want to venture into a custom PC to replace his current HP - and the PSU would work in the new machine and save him from having to buy another. And a 500w or 600w supply should be more than adequate for today's hardware that draws more power. Granted, he could probably get by with a 450w but just the same it would leave plenty of room for anything he might want to install. Better too much available power than not enough and cause hardware issues.

On a side note, my dual slot2 P3 1.0ghz server uses a 550w supply. My single socket CPU P3 tower uses a 425w. I use PC Power and Cooling PSU's.

geez is like talking to a wall. Is my post that hard to comprehend? i know what he wanted and I gave my opinion that he should build a new custom system and to start that by buying a new power supply that would be more than adequate to power it.

the 500-600W I gave him is an estimate that should cover most modern computers and a few future upgrades. And as far as power supplies go is always better to ERR on the plus side to ensure adequate functionality.

I got a raidmax cobra case and 400 watt psu for 60 shipped. The psu certainly is not the best, but better then my stock compaq one, and you can always upgrade later.
