They all just arrived about 20mins ago, but now I'm having second thoughts about whether I have enough power for future expansions.
I know that this is more than ample power as is, but I may want to get another HD4850 in the near future when I have a little more money.
My question is if this current PSU has enough juice for 2 HD4850, and if not, how much will I need? Recommendations much appreciated, but please keep in mind that I am working within a budge somewhat, so I'm looking at around $100 for the PSU. The cheaper the better .
im a 100% sure. it will be more then enough.
look at my rig. im running it on the same psu i have 2 gtx260 which consume much more power and i have a quad core.
ur system will probably use 350-400w max.
Ditch the OCZ Plat and get some Reapers instead. Ive had my 1066 Reapers OC'ed to 1200mhz for about 2 days once and they remained cool to the touch man, the little copper heatpipe on them actually does work, might be worth the extra $$ if you are paranoid about those things like I am.
Also, 500W on a quality PSU should be alright, but like others have said, its pushing it, I wouldnt go and add multiple hard drives abound and what not.
- 1 DVDRW-ROM bay draws 2.0A MAX (that's one hungry unit though, avg is 1.8A on recording).
- 1 DVD-ROM bay draws 1.1A avg (not sure is this amount though...).
- 1 HDD (WD Caviar RE2, power hog) 10W -> ~0.9A.
Now, think about 80% efficiency overall, but 99% efficiency on those 12V rails. Make the math and see for yourself.
Thanks for your answers, everybody. I guess I'll be keeping the PSU after all. And yeah, like I was saying, at other than the aforementioned components, I won't be adding anything else - except maybe that 2nd HD4850.
That power supply should be fine. That Antec could be compared to some of the cheaply made 600W units. In the off chance that it isn't, that power supply should switch itself off if you draw too much power. You should also notice that high pitched whine that comes with pushing a power supply to it's limits. So yeah if you put in another 4850 and your PC doesn't shut itself off then your fine, if it does just upgrade your power supply ^_^
