Solved I need a powerful small Power Supply Unit for a slimline PC

Specs: Windows 64, Athlon II X2 215 Processor 2.7Ghz/4GB ram
Basically I want to upgrade to a gaming low profile graphics cards, but my Slimline small form factor PC only has a small 220W PSU.
Every good low profile card needs anywhere from 400-500 watts of power & aren't compatible with the default one inside.

My PC is a Acer Aspire X1301:

Here is the official link for the 220 W PSU

I found a replacement that give an whopping 30 extra watts!

Is it possible for me to add a PSU to my PC that will fit & will have at least 400W?
I think I need a ATX mini/micro PSU from various sites I read.

I never replaced or added anything to a PC. I'm amazing I even knew how to open the case to look inside, so I'm totally clueless on what to do & what to look for.

✔ Best Answer
Your PSU has only 14A on the +12v rail, that's the important spec. You're going to neeed a PSU with at least 25A. The replacement you linked to is garbage & WAY too expensive for what you'd be getting.

"Every good low profile card needs anywhere from 400-500 watts of power"

No card needs that much wattage. Lower end gaming cards get all their power from the PCIe slot & use less than 75W. Cards that need the 6-pin PCIe plug use between 75-150W. And some cards require more than one PCIe plug. Card manufacturer's err on the side of caution when recommending PSU requirements & take the entire system into consideration.

You have 2 options:

1. find as good as PSU as possible then find as good a low profile card as you can find that won't overload it. Something like this:

2. transfer all the Acer hardware into a standard ATX case, then you'll have all sorts of choices for PSUs & cards. See the following article with lots of good pics:

Thanks for the quick reply, so that power supply unit you linked will fit & is compatible with my system?
I thought I needed a ATX specific PSU?

I do have a spare HP tower case, that I could try & attempt to empty & then try transferring all my Acer components into it. I do like the compact & slim design though & would like to keep it if possible.

Would my CPU & 4GB ram along with the Radeon HD 6670 1GB GDDR5 be able to handle current PC games at high settings or would they be a slideshow?

I'm not talking Crysis 3 or Battlefield 3 at ultra settings, just regular games like Batman Arkham City, Grid 2 & Dark Souls at 60fps at 1024 x 768 with all setting set to high & AA enabled?
Or is that asking too much out of a 1GB GDDR5 card?

riider laid it all out for you...

TFX simply means it's a small form factor psu.

Or is that asking too much out of a 1GB GDDR5 card?

Not that card it ain't. It's very capable; you should be able to plug it in and get busy.

Just to clarify, can I run the low profile Radeon HD 6670 on my current PSU or do I need to buy the one you linked?

People act like your system will be ruined & short circuit if you try to hook it up with just a 220watt power supply.

According to the following article, the Radeon HD 6670 uses approx 58W under full load. I can't tell you for sure if it would work with your 220W PSU or not. All I can say is, it might.
