Need psu, motherboard connections odd

[ElBurro25]

Recently ended up buying a pc, a Gateway Intel Core i5 8GB 1TB HDD Capacity Desktop PC DX4885-UR21, from neweeg, (link: http://www.newegg.com/Product/Product.aspx?Item=N82E16883113262&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-)
Well i notice that the pc had a very low psu at 300 watt, so i wanted to buy a new one. However, i opened it up and notice that the mb has a 4 pin and 16 pin connection from the current psu. I researched and i can't find a proper psu that will fit. This is the current psu (link: http://www.plugloadsolutions.com/psu_reports/FSP%20TECHNOLOGY%20INC._FSP300-40AABA_300W_ECOS%203484_Report.pdf) but its has a 4 pin and 16 pin connectors not a 20 pin, looks like its proprietary.
I need a new psu, if i can't find one i will try to return it.

That is some weird Acer motherboard with proprietary connections. I would contact Acer or Gateway.

Did, had no luck. Told me not to touch anything on it

Can you find a model number on the MB? Maybe take a pic of the board?

If you are wanting to game with the PC, the 300W PSU will be a bit of a bottleneck for finding a powerful gfx card. But the fastest card available right now that can run off just the 75W PCIe x16 slot's power alone is the AMD Radeon HD 7750 with GDDR5 memory. Examples: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709%20600007797&IsNodeId=1&Description=hd%207750&name=GDDR5&Order=BESTMATCH

Your PSU's 2 x +12V rails rated at 16A and 14A will be sufficient for that card. I have run the HD 7750 on a PSU with those same exact specs and had room to spare. The little HD 7750 is an amazing card for the money. It will run most of today's games at med to high-ish settings @ 1080p resolution. At lower resolution, you can really turn up the in-game settings.

Look very closely and carefully, I think you will find this is a proprietary 12-pin main power connector, not a 16-pin. . [I have searched the net for cases of Acer or Gateway proprietary power connectors, and there' are numerous citations of the proprietary 12-pin, and yours is the only citation of a proprietary 16-pin that I am aware of. . If it's really a 16-pin, I would very much like to see a clear, close-up photo of it.]

You will not find any plug-and-play PSU's that will work with the proprietary Gateway 12-pin main power connector. . [There are some Dells (and maybe some other brands) that include a 12-pin connector of the same geometric shape, but not as a main power connector.]

Whether or not you install a video card of any kind, I would upgrade to a good-quality PSW as soon as possible. . I would not be surprised if the power supply were to fail right around the time the warranty expires (or sooner under heavy use). . And when cheap power supplies fail, it is not unknown for the other components of the system to be damaged along with the power supply.

I recommend that you get a quality PSU, and do whatever DIY work it takes [or get some friendly knowledgeable assistance, or pay an experienced tech] to accomplish the install. . For an outline of the DIY work needed, check out:

I recommend that you get a well-reviewed PSU from Antec, Corsair, Enermax, PC Power and Cooling, Seasonic, Silverstone, Thermaltake, etc. of 350 watts or more, taking into account any planned upgrades for the PC, especially possible addition of a dedicated video/graphics card. (If short of funds, even a good used older model would be preferable to leaving a what could very well be a bad apple in your machine.)

Actually, FSP used to make some decent quality units. 2nd and 3rd tier according to the list compiled by Xtreme Systems:

I bought a 500W FSP for one of my budget builds many years ago and it is still providing its owner with great service.

I wouldn't dismiss this odd proprietary unit so soon. Although, it may indeed be one of FSP's low-end models. Btw, I think this is the PSU the OP has in his Gateway: http://www.fspgroupusa.com/fsp30060tha/p/565.html
And this may be the std 24 pin ATX version of it: http://www.newegg.com/Product/Product.aspx?Item=N82E16817104075

I have no specific experience with any FSP units, so your comment is pertinent and appreciated.

When I went to the OP's psu link, I found that the link identifies that PSU model number as FSP300-40AABA.

At least some [not necessarily all] of the Gateway DX4885-UR21 production has the DSP-300AB-82A [by Delta Electronic, Inc], based on the photos of the interior of the Gateway DX4885-UR21 at:
http://www.newegg.com/Product/Product.aspx?Item=N82E16883113262
I only found two links to this model, the most informative of which was this pdf file:
http://www.plugloadsolutions.com/psu_reports/DELTA%20ELECTRONICS%20INC_DPS-300AB-82%20A_300W_ECOS%203461_Report.pdf

I wouldn't be surprised if the FSP300-40AABA and the DSP-300AB-82A both turned out to be the very same unit underneath the "FSP" and "DSP" adhesive labels, and that both turned out to be "rebadged" models of a generic minimum-cost Chinese unit. [not saying I know this, just that I wouldn't be surprised if true]

Newegg sells a line of FSP psu's ranging from $35 to $75 [not including the FSP300-40AABA], all of them with 4 out of 5 eggs or better.

Newegg also sells models of Delta's ranging from $42 to $1,146 [not including the DSP-300AB-82A], all unreviewed at this time.

But -- even though they have an 80+ sticker -- I have to say that I seriously wonder whether the FSP300-40AABA or the DSP-300AB-82A is comparable in build quality to Newegg's $35 FSP retail model or the $42 Delta retail model.

For me, even more than the question of "how long will it last?" are the questions "how clean is the power going to the other expensive components in the system?" and "if it does die on my watch, in what manner will it die?"

I am worried that Acer and Gateway tend to "cut corners" as much as they can get away with on the power supplies in their pre-builts, especially as compared to the included CPU and chipset that are Intel based.

And, rightly or wrongly, I tend to believe that cheaping out on memory, motherboard components, hard drives is less consequential (over the lifetime of the PC) than cheaping out on the PSU.

BACKGROUND: . Way back in 2007, I bought an eMachines T3522 [a Black-Friday special that I'm using right now to type this answer], promptly removed the stock Bestec Power Supply [which had all standard ATX connectors], and installed a 350W Vantec VAN-350N Power Supply [purchased used off eBay, manufactured 2004, warranty expired 2007, still working here in 2014], after reading numerous online horror stories of how the stock PSU's in some eMachine product lines were failing relatively quickly, and often destroying motherboards when they failed. . [Gateway bought eMachines in 2004, and Acer bought Gateway in 2007, according to Wikipedia.]
