Replace new PSU?

By fimbles · 9 replies
Sep 20, 2009
  1. Should i replace my 3 month old power supply? I have no issues with it, but am a little worried because it was a "cheap" one.

    Its a HEC/ winpower 850 watt.


    Ive read a few reviews about HEC power supplys in general and they seem to get pretty good reviews. My pc needs around 575 watts to run according to my gpu manual. Does anyone have any experience with this brand??

    Thanks in advance!

    If I remember, it is not all that good.

    Are you worried about the power supply damaging your system?

    Here's a post by Raybay in a thread I read a while ago that might help you.

    Thanks for the replies. Yes im worried it may pack up and take my other components with it.

    Raybay has said that HEC is indeed an awful PSU. I cant seem to find a UL label, Though it may just be stuck on a non visable side of my PSU. Does this insinuate it is a pirate?

    The problem im having is trying to identify exactly who makes it. The link i posted previously actually has a diffrent model number than my psu, Though it looks identical.

    If i google the model no ( Win power EA4G-850) i just find the brand advance power supplies??

    I would not worry that it was a fake. I posted that more to show the list of reliable PSU's verse those that are not so reliable or even terrible.

    I think you should if the problem occurs regarding that PSU then you must change it because while using computer you have problem coming of heat sinking and other... Thanks for sharing...

    You should be okay IMO, since your system probably does not pull more than 400W. Even if the PSU is overrated, you should be on the safe side IMO. Just be sure you have some good airflow in the case, since some of these cheap PSU brands tend to use cheap caps that can't tolerate much heat.

    Thank you for all the replies. My mind has been put at rest!

    Ill keep hold of it for now since i do have pretty good airflow in my case, And upgrade when i upgrade to sli/ dx11.

    You can also find lots of PSU reviews here:

    As Rage_3K said your current PSU should be ok for now. You will probably want to replace it if you ever upgrade your video card and don't even think of maxing it out. Also these cheap PSUs tend to last 2-3 years (usually the life of the low quality filter caps in them) oftain taking out other components when they fail so you should be fine for now but you may seriously want to consider replaceing it in 12-18 months even if you don't upgrade anything. Generally as long as you stick to Corsair, Seasonic, PC Power & Cooling, FSP, Enermax, and the mid to highend Antecs you shouldn't have any problems as long as you get one with sufficient capacity.
