Trying to find PSU efficiency

Edward Gelernt · Apr 21, 2013

For my recent PC budget build, my PSU was the 300W unit included in http://www.newegg.com/Product/Product.aspx?Item=N82E16811154068&IsVirtualParent=1 . Because this computer is for my sister and she will trying to spend as little money as possible on bills, I'm trying to find the efficiency of the PSU to determine whether or not upgrading to an 80 Plus certified PSU is worth it. However, I can't seem to find a way to determine the efficiency other than using complex voltage readers, none of which I have or have any intention of buying. Any suggestions?

Thanks in advance for the help!

Rest assured it is a lower end efficiency psu. But upgrading to gold or platinum would be cost effective? Use what you have and see how bad the bills are. Is she going to run it all day for work or just for checking facebook/e-mails ?

I wasn't intending to upgrade to gold or platinum, just normal certification or maybe bronze. What would you think would be APPROXIMATELY the efficiency? (As in, I have no idea; closer to 50% or 80%? Even that much would help.)

No way of finding the power efficiency but she shouldn't worry about the bills...PC's don't take much energy anyway

While I understand being on a tight budget, just remember......You get what you pay for! This is a bargain basement case with a very low-end power supply (as mentioned by ur6beersaway) that I wouldn't trust to operate anything electronic. You/she would be much better off getting a PSU from a reputable/quality manufacturer, even if it means spending a little more money or having to wait and save just a tad more before getting the computer/parts.

There's nothing to worry about the PSU blowing so quick. There's nothing power extensive in the system for it to blow...

In case it helps, my config is:
MOTHERBOARD: Gigabyte H77-DS3H
CPU: Intel Core i3-3225
MEMORY: Kingston HyperX Blue 2x2GB DDR3 1600
GRAPHICS: onboard
HDD: WD Caviar Blue 500GB 7200RPM (OEM)
OPTICAL DRIVE: Lite-On Super AllWrite DVD+/-RW
OTHER: Logisys multi-card reader; Rosewill 300mbps b/g/n wireless adapter

That's a horrible power supply, even on a light load it can still blow and destroy the system. The cheap ones have even been known to catch fire. Protect your investment and by a decent power supply.

Newegg takes pictures and you can see the model number: SL-8320BTX. And that points to this psu which is 65%. http://www.apextechusa.com/products.asp?pID=172
