Thats the power supply unit I have, fantastic little unit.
That is a rubbish unit that has very low efficiency , no PFC, low amperage on the 12V rail and and is rated at 25oC, which is hardly going to be the conditions most psu's run at. Rosewill PSU's come from various manufacturers, some very bad, some just ok, and others unknown. I would avoid them.

El DJ the best solution is to get a quality name brand PSU with high efficiency (>80%) and solid single rail delivery. What specs is your machine?

I have had the RD500 500W from Rosewill for almost 1.5 years now and I haven't had any problems.

again, rubbish efficiency (65%) WHOA, no pfc, low powered 12V rail. CRAP!

just stick to quality El DJ, corsair, antec etc. Remember, it has little to do with the wattage and more to do with the amperage and efficiency of the 12V rail. What specs are you trying to run?

Dude 38A on the 12+ rail is plenty. I was just giving my contribution by sharing that at least my unit has worked perfectly well. Running an HD3870 + Overclocked CPU without problems. Price is perfect too.

You know, not all people can afford Corsair HX/TX or OCZ GameXStream series.

Dude...

Your psu has two rails, one with 15A and one with 16A, total 31A http://www.newegg.com/Product/Produc...82E16817182044 - but hang on you cannot just add them up ok?

Under ATX design specifications, your 12V+2 rail is dedicated to the CPU, leaving only 15A for the rest of your system. You are grossly underpowerd using RD500 with your system, in fact i am suprised that you haven't run into trouble. But you may still have problems, as the HD3870 hasn't been out for 1.5 years, so we'll see shortly enough i would imagine. In the meantime, i would suggest taking note of your 12V rail stability, and the amount of hot air coming out of the PSU, as a rubbish unit like that under near-full load will eventually fail.

What I am saying is, who can afford to potentially lose their RAM and GPU and PSU if it fails - it is simply poor advice to suggest a Rosewill is good quality! My point stands - any PSU with 65% efficiency, no PFC etc is CRAP! Regardless of what you can afford. Read the Multi/Single Rail PSU info in my sig if you want more information.

The OP's suggested PSU only has 20A for the rest of the system, which is below what i would recommend for a PCIe card, however he needs to specify what his system consists of, so that we can determine his power requirements, but his original question was essentially - is a Rosewill PSU quality, answer NO.

I would much rather spend an additional £30 on this: http://www.newegg.com/Product/Produc...82E16817139001 which is $110 after rebate. You get what you pay for, but i guess if you choose the PSU by its colour, then you are asking for trouble. If you have a little more to spend than this is an absolute bargain http://www.newegg.com/Product/Produc...82E16817139006

Ok, all I'm trying to say is that I do not agree that Rosewill PSU's are crap. Do you care on what I agree on or not? No! That's right. My PSU hasn't failed and that's all I wanted to share.

You're taking this too far, maybe technically Rosewill PSU's are not the best but IN MY OPINION AND IN MY CASE, they are not trash!

Have a good day
