Default Need help identifying a PSU

I need help identifying the PSU in my computer. I'm looking to upgrade my graphics card but I didn't build this computer, so I want to make sure my PSU can handle it before I do, but there are no real identifying markings. I was told I could find help here.

Is that enough to go on? What is the wattage?

No it isn't, take it out and get some high res pics of the spec sticker.

I sure hope you're trolling, boy.
Careful what you wish for... You just might get it.

You're not going to find identifying markers on the PSU if you don't pull it out of the chassis first.

At least unscrew it and flip it on it's side if you don't want to unplug all of your cables.

So far, I've identified it as black, of middling quality or worse.

Proper fan guard shows it's not utterly cheap, they usually go with a stamped grill, unless they're trying to pretend to be worth having...

On the other hand, lack of sleeve on the cables looks very cheap.

Based on the thin cables and the reduced number of yellow cables, it's probably one of those cheaper power supplies, that do 400 watts or so with some effort.

In the end, it matters a lot what kind of video card you want to plug in your computer, and what components (especially processor) you have now.

Cheaper video cards with just one PCI Express connector may need little energy, so I could say it's 90% chance it will work just fine, but with other cards, it really depends on the video card.

Is the power supply equipped with a switch to change between 110v and 220-240v ? If so, it's an older design which won't do more than 300-400 real watts... otherwise I can't tell from those pictures.
How many hard disk connectors and pci express connector does the psu have?
