Upgrading Power Supply in Older HP P6-2133W

Thinking of upgrading Power supply in older Pre Built HP P6-2133W, if it isn't standard power supply, suppose I can have a local PC shop do the upgrade, PC is used for mainly Mom's email, and online shopping/bill paying at times

Machine was bought in 2012, and used heavily when it was previously my machine, and now used less, but she leaves it on with sleep mode pretty often, so thinking will add that to my list of 2018 upgrades this year

From HP Pavilion p6-2133w Desktop PC Product Specifications | HP® Customer Support it looks like it is a standard ATX power supply. You can check the label on your PSU to confirm - for these basic desktop systems OEMs are generally going to use off-the-shelf components.

Yeah should replace that supply, though does have LED to alert when it might be going bad, still green at this point, but who knows how long the OEM supply will last in that model, even if I do decide to fully upgrade it early, at least will be preventative maintenance, Main Desktop plan on upgrading supply in eventually for future video card upgrade

yes gonna look at the measurements of that particular one, when I do next dust clean out that's due sometime soon here, then will get the measurements at the same time, and go from there

Why do you wish to upgrade the PSU? That would typically be done to support a high-powered graphics card, but you make no mention of that. (I doubt that your mother needs a new graphics car for email and online bill paying.)

There is some chance that it could fail, but it might be good for years yet.

If you intend to proceed with the upgrade, HP lists the PSU dimensions as 150mm x 140mm x 86mm (5.9 x 5.5 x 3.4 inches). That seems to be a fairly standard size, although there are much larger ones out there as well.

Yeah well I was thinking of doing it as preventative maintenance, but then again guess not an emergency to upgrade PSU in Mothers Computer, I know for my main desktop gonna upgrade it to support a higher graphics card eventually.

Previously that computer was my old old one and I ran it really hard with gaming, video editing, and usually was on 24 hours, or in sleep mode, she still uses it leaving on most of the time, and sleep mode, as old manual of her old system had in it avoid shutting down unless changing hardware, not sure why that slimline had that in the manual at all, but followed that direction for years, til power supply went in the slimline, hence why she got my old one, and I got a newer one

then upgraded again early this year due to problem changing video card on my AMD FX system, where the Video card was right against the chipset heatsink, so wasn't really much room for 2 slot AMD card, so choose a G11CD-K for my newer system
