What format is my PSU

[Binar]

I bought a cheap ACER because I liked the factory form. I upgraded the RAM, SSD, and installed a custom gtx 750. Now I'd like to upgrade the PSU
http://www.amazon.com/Acer-eMachines-DPS-220UB-PS-5221-06-PY-22009-003/dp/B002MFVM94/ this would be the actual PSU and I'm looking for something bigger than 220W

I can't find anything bigger because I can't figure out what factory form this PSU is...Any help, please?

Proprietary format with no upgrade unless they made a larger PSU specific for your computer, most likely.

Should have gone with one of the ITX cases that use a standard SFX PSU. Preferably one that can fit Silverstone's SFX-L 500w PSU (slightly larger so that it can use a 120mm fan).

I was afraid I might get that answer. I found a 3rd party seller on ebay that manufactured 300W PSU but I'm not sure I want to go that route.
The reason I got the PC was the price. The CPU alone was worth more than what I paid.

Anyway, ty for taking the time to answer me

From some brief research, it seems to be a Flex ATX power supply with a weird notch on the back of the case, probably for fitting an optical drive or something.

You might be able to shoehorn something like this:

Into your computer. I don't know the length of your PSU, but this one seems to be shorter and may work. You'll have to do some measurements to check though.

If I were you, I would measure the power supply and see which format comes closest in size (As GiGaBiTe says, FlexATX does look close) and either cut out the back panel a bit or make a bracket for a slightly smaller power supply.

I doubt you'd need more PSU honestly.

I doubt you'd need more PSU honestly.

I hope I don't either but I might cutting it close:
I3 4130CPU
500gb SSD Samsung 850 3d EVO
Zotac GTX 750 (low profile) with custom fan
optical drive
2 x 8gb Crucial ballistics PC3-12800
wifi module

i3: Probably about 25-50 watts.
GTX 750: 50-100 watts.
Everything else: 50 watts.

You should be fine.

You can always run an external power supply too. Something that does several amps at 12V or 5V and plug it into extra stuff like drives. Open up some headroom for the internal one.
