tested and using greenstar 550w for 9800gt...i tink 9800gt consumes more power den 4850

Got noise? @@, cause thing is. If I play games like Crysis (FPS doesn't go above 60 most of the time) but the GC is still under almost max load right? No noise, but if simple programs, like maybe during Crysis menu, the fps shoots up to 800-999 or something, and the PSU starts to make noise.

wel...not reallylar...din really notice that...but i notice the sound from the loud fan of palit 9800gt..haha

i tested greenstar with my 4850GS. no problem. no such noise.

wait.....
my greenstar 'whine' when i play crysis warhead and the problem is very recent.maybe its bcoz i always stress test my rig since i first got this PSU.

Noise only occur say, in menu of games with vsync off when the FPS shoots up really high. Let's say the FPS about 600-900 also don't have such noise? It is some electrical noise actually from the PSU.

oic...dunolar...but some pc components will generate noise when load..

This electrical noise, is from the PSU.

1. I placed the PSU outside of my case and the noise still comes from there.

2. I tried with another PSU to power my system up, no such noise though.

So,

this considered a problem? Since Greenstar you claim no noise.

problem means faulty?

AM USING THE 650w COMPARING TO OTHER BRANDS ITS CHEAPER AND THE PREFORM IS GOOD

use v-power 550watt almost 3 month..
wht can i said,good psu compare with it price..
can oc my x2 5600@3.2ghz with no prob..

yea..i tink this psu is good enuf for budget users

Using it about 3 months, now sometimes got buzzing sound of out of a sudden ._.

shud be fine..most cm extreme user oso faced tat

Now the buzzing gets longer and more irritating!

The PSU didn't had this sort of noise when it was new. Sigh... Sign of PSU dying huh?

welcome to faulty club

notystar_exe, yours is the same case as well? So you RMA-ed it?

wanna see huntkey v-power 550W go KABOOM when loading it with 550W of power? Really shocking. Apparently the perfect wattage output is 60% (330W) of stated 550W load, reaching the efficiency of 80%+. When a load of 80% (440W), the efficiency drops to 70%+. When a 100% load (550W) is applied, it exploded.

"If you follow closely our power supply reviews you know that two models we reviewed from Huntkey Green Star series – 400 W, sold in the US as Dynex 400 W, and 450 W – exploded during our tests. So we decided to get a more “powerful” model, V-Power 550 W, to see if it has the same fate as its sisters. Is V-Power 550 W a good power supply or it is as flawed as the members from the Green Star family? Check it out.

The funny thing is that the manufacturer's website lists both rails at 18 A but the sticker clearly lists one rail at 16 A and the other at 18 A. But, like we already explained, this unit uses exactly the same rectifiers as used on Green Star 400 W and Green Star 450 W from the same manufacturer.

What exploded were the two switching transistors. When the power supply explodes it means that the primary side is under dimensioned. When the secondary side is under dimensioned the power supply dies silently, because when a rectifier burns the short-circuit protection enters immediately in action shutting down the power supply.

So Huntkey should have used more powerful transistors and added a heatsink to the rectifying bridge, plus using rectifiers with higher current limits for the +12 V output."


Marketing gimmick. 550W my ass.

If u have high end cpu, spend a few hundred bucks more on PC&C or Corsair/OCZ or other brands that uses the same OEM with the brands mentioned.
