Guide for Selecting a Power Supply

[mikk311]

Hi Big_Dave

Yes, sure did. No optional psu's or pinout's on the "pwr cmd" connecter there.

This question is actually the same as the one capitol-m asks. The partnumber of the PSU is 508154-001 and as far as I can find out there is no way of upgrading that part - due to the proprietary connector.

Please tell me I am wrong?

Thanks

All signs point to "no, you are not wrong". All information i have obtained is consistent with there being a proprietary PSU with a 6-pin main power connector.

I have been unable to find any replacement PCU's with a higher wattage, it seems replacement with stock components is the only option. Even aftermarket and brandless PSU's do not support this odd format.

It also seems that this is currently one of very few minitower systems still incorporating the proprietary PSU...For reasons unknown.

capitol-m,

I agree with your assertion.

Sorry if this is a bit redundant but I am being cautious. I recently purchased a HP Pavilion P6620f(250w PSU) and am need of changing the PSU on it on account that i want to install an EVGA GeForce GTS 450 FTW(400w min). The thing is I'm not exactly sure what to buy as far as PSU's go. I don't quite understand how to choose a psu that best fixes my situation and was hoping someone here would be able to help me. Thanks!

Buy THIS ONE.

Yes it will fit. I've got the same one in my HP Pavilion.:smileyhappy:

The Corsair VX 550 is a good choice.

I was wondering if you wonderful people could help me out here, as I'm not familiar with HP's (anymore...last one I had was over 6 years ago).  My family decided to buy me a computer...and it ended up being an HP Pavilion.  A s5623w-b slim, to be exact.  Part of my famly would like me to play World of Warcraft with them, but this computer, while it can play WoW, does not play it well (20FPS with lowest graphics settings...not much better than the computer I am replacing...).

So, because I am not satisfied with the graphics, I would like to upgrade it, but doing so on the power supply this one currently has (220v) is NOT going to happen (a little pow wow with my geeky friend who builds his own computers made that one pretty clear).  Is it even possible to upgrade the power supply on this?

That's what I got on HP Part Surfer.  Just the 220 and nothing else.  If there's anyone here familiar with this model that can give me some tips or point me in the right direction, I'd appreciate it.  I'm more of a software person, rather than hardware, so I have to turn to everyone else for this sort of thing >_>  Help is very appreciated, though.  I think this would be a solid computer with a better power supply and video card.

milkway44,

Google the power supply part number.  You might be able to find a bigger PSU.  If you should decide to replace the PSU, then know what the 12+ volt bus amperage is before you buy.  Match the 12+ volt bus amperage to the video card that you are considering. The slimline cabinet will require a low profile video card.

A word of caution is that a bigger PSU and video card will generate more heat in a small cabinet.
