Upgrade PSU or no

[alecz24]

Hi all.

Sorry for bothering, but i need some professional help here

My specs:
CPU: AMD Athlon 64 LE-1640
GPU: Sapphire Ati HD 5670 (512Mb DDR5/128bit)
RAM: 1x 2Gb DDR2 800Mhz
MOBO: AsRock N61P-S
HDD: 2x IDE HDD (1x40Gb and 1x160Gb) - plugging the DVDROM only when changing OS -replacing the 160Gb HDD
PSU: MaxCube Nira 400w

At this stage, the PC is quite "ok", no problems caused by low PSU, however, after some time on "intensive" games, the GPU does get quite hot compared to the GPU reviews.

I'm planning on replacing:

CPU: AMD Athlon II X2 250
MOBO: ASRock 760GM-GS3
RAM: 2x Sycron 2GB DDR3 1333MHz
HDD: Samsung 320GB SATA-II 7200 rpm 16MB SpinPoint F4

Will the MaxCube Nira do the job (handle the system even on allmost 100% load)?Or should I upgrade the PSU too?
In case the Nira won't do the job, I tought about a Inter-Tech Energon 650w, wich has a efficiency of 75-85%, CWT, SCP, OCP, OVP, and 4x 12v rails of 18A/18A/18A/18A.It has 4.7/5 in 30 reviews, full positive opinions on systems that are twice as better as mine.

For the system i want to build, eXtreme Power Supply Calculator says the minimum PSU wattage is 280W - 24A on the 12v rail - and recommended is 330w - 28A on the 12v rail -
What are your opinions?Is the Nira ok or do i need the Energon?

Welcome to TechIM!

We only recommend brand name power supplies, because all power supplies are not the same.
Nether of the brands you mention are known brand names.
Power Supply Info

The fact is though, you are not changing the video card, and it is an average setup, so the power requirements, of 400watt have not changed.

I would get a brand name 400watt, from our list, it will be less than $50.
