hello,

i need to know if i need to update my power supply.
if i'm right i see my max output is 800w.

but i'm getting
cpu 3770K
mobo will be msi mpower
i will get 4 x 8gb ddr3 dunno what mhz atm
2 x msi 660gtx
i have 1 water cooling h60
5 x enermax vegas duo 140mm
2 x 240mm in case (xpredator)
1 dvd + 1 dvd-rw
1 ssd going to add 1 more
2 HDD one from 540gb one from 250 or something like it going to add 1 from 2/3TB
1 monitor 24inch and 1 from 17
keyboard g11 mouse mx518
headset plugged and some other crap like card reader webcam cables for loading up phone etc.
printer/scanner etc all the crap:)

would my power supply that i guess is 800W be enough? its a old one
i saw this on it model # 2474 LPZ-26-50 2 * SATA PCI
output 360 max 800w it show in small letters.. lemme know;)
 
Taking ~140 W TDP for each GPU and 150 W (77 W @ stock voltage) for the CPU (on a serious overvolt, not sure how much it actually would be, just assuming something high to be on the safe side), your PSU should have plenty of enough power.

However, since you're saying it's a rather old unit and Google does not spit out any info on that model number I would recommend getting a new PSU anyway, something like the Corsair AX760i should be quite sufficient (you can go for an 860 W unit if you want, but it's not really needed imho). Seasonic also make excellent PSU's you can also take a look at those.

Running an old PSU, let alone something that's as obscure as your unit appears to be, is not something I would do. Best case scenario, you don't get good overclocks (I'm assuming you'd want to overclock, judging from M/B and CPU ;)), worst case scenario you have something with transient spikes, high ripple and bad voltage regulation which will fry your shiny new components :(

EDIT: Just as a side note: the remaining components (M/B, RAM, HDD, SSD etc.) do not use a lot of power. One HDD uses 10 W max. (all I've actually seen use less), so you only need to worry about those if you have a lot of HDDs. The rest really is rather negligible. Older M/B used more power, but the new generation is ~6.2W since most of the functionality that used to reside in the M/B chipset has been moved to the CPU.

didn't have any problems tbh with it:) but it's at least 4 years old..

Most PSUs with dubious quality work quite alright as long as you don't stress them too much. Also, dubious of course does not mean bad by definition, it might well be that you actually have a good unit, but since the PSU has the potential to break pretty much any component in your PC I just wouldn't risk it.

ill have a look but to be honest ill not overclock my pc untill i have a new power supply then :D i need to buy new mobo cpu gpu's ddr3 will cost me lot and then new power supply from 100-200euro?
maybe this one?

this one is nice little bit like my case with lot leds:P

Both good choices.

EDIT, because simultaneous post: As mentioned, the AX series would offer modularity (and higher efficiency), but of course it does cost more. Quality- and power-wise these will be absolutely ok.

Well first you have to differentiate between the OEMs and the actual brands you buy. The most reputable OEMs I know are Seasonic and Delta (I'm sure there are others that are also good).

The OEMs are the ones that actually make the PSU, possibly with design and engineering input from the brand which gets to put its sticker on the PSU. Seasonic make PSUs for other brands as well as sell PSUs with their own name on them. Corsair do not actually produce any PSUs (as far as I know), and quite a few of their units are actually produced by Seasonic. Many other brands also use Seasonic as an OEM.

Delta make primarily high-end server PSUs, under their own name as well as in the function of an OEM. I don't know too much about them though.

Have a look here. They usually write in every review which is the OEM of the PSU they've tested.

One exception to this is Enermax, which actually design and produce their PSUs themselves. They range from good to excellent (at least the ones I've heard of), but they do carry a hefty price premium (as far as I know due to excellent build quality and the use of very high quality components, I have an Enermax myself).

This whole OEM business is for example while it might very well be that the first PSU a brand sells is utter crap, and the successor model is fantastic. That's not necessarily because they have suddenly gotten better at making PSUs but simply because they switched OEMs and the new OEM offers better platforms as an engineering starting point, better production quality and better component choice etc.

There are other brands that offer great PSUs as well (BeQuiet! come to mind, who also use Seasonic as an OEM for some of their units, and as mentioned, Enermax), the thing with Corsair and Seasonic is that I have never heard of a bad PSU of theirs, so I can recommend them without having to do three hours of research first on their offerings ;).

EDIT: I overlooked your question regarding the HX850. See reviews here, here and here. Bottom line: It's a very good unit.

I've been able to find this review on the 87+, and this review on the NAXN 850. I've also found a review on the NAXN 750 in which it is mentioned that that specific unit is not actually made by Enermax (so much for my earlier statement :lol: ), I do not know if that's also true for the 850 version. The 87+ is however made by Enermax (not that this really matters, what's important is not who makes what but simply having good quality control, regardless of manufacturer/OEM). The 87+ seems to be a very good unit, and the NAXN (which is Enermax' entry line) appears to be quite good, if nothing extraordinary. Both units suffer from not exactly stunning regulation on the 3.3V rail, but seem to otherwise perform very well.

Be aware though, that just because Enermax units are more expensive does not mean they are necessarily better than Seasonic's or Corsair's offerings. Personally I would probably rate Seasonic at the top of the food chain regarding performance and quality from the OEM's I've heard/read about simply because they have so consistently produced not just good but great PSUs.

What makes Enermax special (and the reason I bought the Platimax 1200) is that they design and manufacture (most of) their own PSUs, and they really do feature absolutely stunning build quality and component choice. Especially for the more expensive components you do of course pay more. And I'm just a sucker for build quality :).

However, since PSU engineering is a rather complex task, they do sometimes suffer from a bit loose voltage regulation (as does the unit I've bought). Nothing out of spec or bad, just not as stunningly good as Seasonic's offerings. This is not true for every Enermax unit (for example, the Platimax 1350 seems to be absolutely phenomenal, but I couldn't find it anywhere to buy here so I went for the 1200 version, which is not quite as good).

Personally, I would probably buy either a Corsair AX760i in your situation, possibly an 860i if I knew (or assumed) that I was going to need more power for more GPUs at some point. For the rig as it currently is, 760 Watts is plenty of power.

However, none of the choices you've listed could be classified as anything other than good as far as I'm aware, so if you are still unsure I suggest reading some reviews on the units that have been mentioned and then making a decision. If you go with one of your listed suggestions, you should be perfectly ok.
 
A 650w unit would be plenty for a setup like that, total power consumption at max load is probably going to be around 400w at most. I'd recommend upgrading the power supply anyways since the unit you have is downright horrible (according to this, it's closer to a 300w unit), but you really don't need to spend 200 euros on a new unit either.

I'd personally recommend this 750w unit. It's similar to the HX in terms of quality being a rebranded Seasonic M12D, but notably cheaper.
