Ugh 400W powering HD 5830 .. ?

post #1 of 33
Thread Starter 
Hello!
I've had this noname brand (is it?) Frontier Technology Inc. KY -400 ATX PSU for over 3-4 years or more , and what i found interesting , and stunning , is that it powers a HD 5830 gfx card i've just got , and also a phenom II X3 (2,8->3,3 OC low i know but still!) ! Check my sig for more info
How is this possible? I was told that the hd 5830 will EAT my 400W power supply , but obviously it won't.. I had to connect 2x molex PCI-E 6pin to the gfx card also , i really didn't think it would work , but it did.. I run every game on MAX and I also tried playing on my plasma 42" with 1080p HD (1960x1040 or whatever) full details and it runs any game on those settings max resolution without problems... I'm stunned seriously...
But i've been thinking , should I upgrade the PSU? Should I expect my PSU to die soon? Or is this one really a miracle?

While it seems to be working, no computer should ever be subjected to being powered by a low-quality generic/budget PSU like that. It could be the death of your computer waiting to happen.

For example: a quality 400W power supply would eat this Frontier Technology unit for a quick snack.

Even if the PSU will power the card I would not do it. It could fry your whole rig if it goes out

Good PSUs harmlessly shut off if they can't handle it. Cheaper ones can die and kill a part of a system, or even an entire system. Some can even start a fire.

How much did it cost you, and what does it look like? How old is it? What's this PSU's +12V capacity?

By the way, a system with the 5830 in it does not consume any respectable amount of power.

Its more than enough if its a good solid PSU, my System, with an Overclocked 5830, pulls 400W from the wall, with an old copy for furmark (to ensure maximum burnability ) and Prime 95, so 400W at 78% efficiency... works out to about 312W which is just great =P

EDIT:
I found the manufacture website, can u please pick it out of the list?
http://www.frontier.com.tw/index.asp...ly&It=standard

And yes you should upgrade your power supply, because when PSU degeneration kicks in... you screwed =P, also it wouldnt hurt to have a new 500W Corsair or Seasonic unit, i wish Phedause (or however u spell it) was here, hes our PSU go to guy

If you really want to know if its a good PSU take it apart and take a picture of the guts and post them up here on the forums and we can tell you by looking at the way it's designed

Sounds like the makings of an old and low-quality unit. I recommend replacing it as soon as you're able to.
