is my power supply too weak ? - Page 2

post #11 of 16
Those numbers look good to me and when compared to this review, voltages are right where they should be for this model. You might be pushing it a little more than I would like for this PSU, but I think you are fine. How long have you had this PSU? Like I said earlier, build quality isn't the best but there is nothing particularly bad about this PSU, except maybe ripple at very high loads. I think you'll be good for a while, but next time you do a major upgrade try to get something a little better.

I'd say that as long as your system is stable, there's no need to upgrade. Also, very rarely is a system truly at "100% full load." Even with an intense gaming session, I wouldn't say that a system is at 100% full load. I agree with The Duke's sentiments about the PSU being the most-overlooked and least-understood component (I'm not assuming to completely understand it). Likewise, I'd say that perhaps the calculations that go into estimating power requirements, while probably very logical and well-thought out, are not necessarily realistic/don't give a super-accurate depiction of how much power a system should have.

I say stick with what you have as long as it's working and providing stable power. When you start having problems, then upgrade.

Those among other things need to be taken into consideration like the 12+ voltage line(s) rather amps. Furthermore, a multi rail total 12v+ amperage does not equal the actual combined 12v+ amp capacity.
Then there is the PFC rating, if it even has one which provides a more stable out put of energy.

So those factors are why, when OCing, more than needed is not a bad idea.
The PS seems to be the least understood component and often neglected in the purchase.
While it is true some manuf. use deceptive wattage ratings, it's already been established how many amps are available on the 12V rail (28A). It is low for a 500W PSU, I would prefer it to be closer to 35A. And yes loads above ~70% for extended periods will decrease lifespan and increase failure rates, that is why I told him he should upgrade eventually but he doesn't have to go and get one right away since the PSU isn't that bad and should be able to handle it for a little while.

Why are you talking about combined 12V ratings? This is a single rail PSU. While it is important to recognize how manufacturers can trick you when figuring combined maximum amperage, I don't see how it is relevant to this PSU.

Also, how does PFC (active or passive) provide more stable power when compared to PSUs with no PFC? Granted if your local electric infrastructre provides unreliable power (brown outs and such), an active PFC will help smooth out some of the dips in voltage but in this scenario you should really have a UPS anyway. Under normal situations, active PFC is only beneficial because it reduces stress on the electrical mains by reducing the VA needed and it makes it easier when traveling to different countries, eliminating the need for adapters and simplifying the manufacturing process (one model instead of multiple versions for each electrical grid). Active or passive PFC doesn't improve DC output quality, it just tends to be added to better quality PSUs but even then it isn't a reliable factor for judging PSUs since many bad PSUs have some form of PFC.

i have had it for a while 3 years+ this thing is so much better than i thought, definitely a worth while buy (got it for $69) it is a beast and has been put through hell so it is a good psu and if i can get a few more months out of it

Man, 3 years. I think that guy deserves a nice retirement in a couple months.
