Hi friends!
This has been causing me a whole lotta stress and confusion considering the wide selection of computer hardware.

I have a stock 380W power supply. I am wondering if it will support what i plan to install or will i have to buy a more powerful supply?

my specs next week will be,

MOBO: M4A78LT-M
PROCESSOR: AMD Phenom II x2 565 80w
RAM: DDR3 2 Sticks 2x2GB
GRAPHICS CARD: Asus radeon HD 5450
HARD DRIVE: SATA 1 TB
DISK DRIVE: DVD+R DL
FRONT BAY CARD READER
And 4 cooling fans not including heatsink.

Will my 380w power all this? I also plan to over clock my phenom.

Please i already tried the power supply calculator and they all tell me something different, so any of your opinions will be highly appreciated thank you!!

enough ... minimum PSU for Radeon 5450 is 22A at 300W, But don't use PSU from Stock case .
power consumption Radeon is just use 380W pure PSU minimal 80+ certificate
* System in IDLE = 154 Watts
* System with GPU in FULL Stress =177 Watts
* Difference (GPU load) =23 Watt

This 380w is only 12v - 15A... So i was looking at that 500w corsair, im guessing that'll do the job right?

Sorry to bother you, sadly I have been struggling with this issue for about a week now. So for the setup I plan to put together you are pretty much saying that my PSU is barley enough to power my Radeon?

What if i decide to install an HIS Radeon HD 4670 instead? I will still be fine with the 500w corsair and being overclocked?

380W doesn't tell us anything. I can point out a review of a Diablotek 500W unit that can't power your setup, but a 380W that can. We need more details then "380W".

When determining what power supply to purchase you should not be focusing on the power supply wattage.

The most important specification you should focus on is the power supply's +12 Volt continuous current rating. The CPU and GPU are powered by the +12 Volt rail(s).

A Radeon HD 5450 has a maximum board power of 19 Watts. This means that the graphics card itself may draw up to 1.6 Amps from the +12 Volt rail. Your 380 Watt power supply with its +12 Volt current rating of 15 Amps, which is considered weak, should be able to handle a system with this graphics card assuming your 380 Watt power supply is actually able to deliver this rated 15 Amps of current.

A Radeon HD 4670 has a maximum board power of 59 Watts. This means that the graphics card itself may draw up to 4.9 Amps from the +12 Volt rail but will actually draw up to 5.4 Amps if you run the FurMark test utility. Your 380 Watt power supply may still be able to run your system with this graphics card because under a typical gaming load the graphics card's current draw is 4 Amps leaving 11 Amps to power the CPU, motherboard, hard disk drive, DVD drive and cooling fans.

The reason I chose the radeon 5450 was because its low power consumption. I was hoping to be able to safely power
MOBO: M4A78LT-M
PROCESSOR: AMD Phenom II x2 565 80w ( I want to OC to make it phenom II x4)
RAM: DDR3 2 Sticks 2x2GB
GRAPHICS CARD: Asus radeon HD 5450
HARD DRIVE: SATA 1 TB
DISK DRIVE: DVD+R DL
FRONT BAY CARD READER
And 4 cooling fans not including heatsink.
With linksys wireless n usb adaptor and asus wireless headset.

Will my 380w AcBel 12v - 15A be able to handle that?

What is the Model number of that AcBel Polytech Inc. 380 Watt power supply?

I thought it should have at least two +12 Volt rails.

I have another 380w power supply. Maybe this one is better and will be able to support the specs I have listed above?

My other 380 PSU is a
Antec
Model Number: TPII - 380

I checked and this one has 16A while my other one has only 15A not much of a difference...

Seems the Antec might be slightly better then the AcBel.
But is it enough to safely power everything listed above?

The Antec TruePower II 380 Watt Continuous Power ATX12V v2.0 (TP-II 380) has a combined +12 Volt continuous current rating of 28 Amps.

It will power a system using either of the graphics cards you have mentioned with no problem with plenty in reserve for overclocking the CPU and GPU.

This power supply's combined +12 Volt current rating is 18 Amps which should in theory be able to power a system using either of the graphics cards you have mentioned.

I had a more powerful system running on a 300W so you will be fine
