Is my power supply enough for now and my coming upgrades?

post #1 of 20
Thread Starter 
I don't know how my PSU is holding up. I have used some online calculators to determine my needed wattage but I have been told they are worse than not checking at all.

CPU: 1090T @ 4Ghz
MOBO: 870a ud3
GPU: gigabyte HD 5770
RAM: G.skill 1600 2x2Gb
SSD: OCZ vertex 2 (removed mechanical drives to my server yesterday)
Fans:
-1x 140mm led (standard front intake)
-1 x 120mm (Standard rear exhaust)
-3 x 140mm TY-140 (2 side intake + 1 top exhaust)

This is my case which has the stock PSU
http://pccasegear.com/index.php?main...ducts_id=13521

and this is as close as I can find for useful PSU information.


Can I just go out and purchase an uber PSU now that will last me for a few years regardless or does it really depend on what i'm doing with the system.

I have heard that if I buy a PSU that is like 1200w and i'm only using 400w for example a lot of energy is wasted converting it or something compared to if I had a 500w PSU using 400w but this just never sat right with me so i'd like that cleared up.


Cheers

I probably wouldn't use that PSU based on this:

Incorrect.
Your computer will pull only the power it needs. A power supply is able to supply what's on the box (generally) as far as DC power is concerned. If your system needs 250w, your system would pull the same amount of power if you were using a 300w or 1500w PSU (at the same efficiency).

Once you begin exceeding the rated threshold, poor efficiency and failures generally occur.

+1 dont use that psu ....
and as far as power ratings concerned...no power is wasted even if u take 1200watt for 400 watt requirement...system will pull only what it needs and psu will supply that much power at its rated efficiency.....

Do some reading, check out the other articles in his sig. It's a wealth of knowledge.

@ beers & ghost_z, thank a lot. Looks like I need a PSU upgrade ASAP... long before I add a custom watercooling cpu loop.

@ justarealguy, thanks for the link I shall do so. I did read in another thread there is no real point trying to figure things out for yourself when it comes to PSU's as there is just too much to know which is why I asked but I am interested and will take a look and try and learn some basics for now.

More questions!

So from what I have just found out in my mind as my next upgrade it makes sense to get a PSU and when getting a PSU would I be right in thinking just to get like a strider 1500 and never have to worry about my PSU again?

Also in my new case upgrade which will probably come after PSU I am lookiing to get something like a http://www.pccasegear.com/index.php?...oducts_id=7597 is there a PSU i can buy that will allow for such long cables (the case is 68cm high) or would I just purchase the cables for example the optical drive that need to be that long when I come to it?

Cheers and thanks again

Yes, there's a lot to learn, but you've got to start somewhere .

Well, unless you're be running 5 GPUs and a seriously overclocked CPU and 10 HDDs, you won't need a 1500w power supply.

Secondly, a high wattage power supply doesn't mean it will last forever. Parts eventually fail, so buy something closer to what your rig will demand and go from there.

You can get cable extensions that will allow you to reach your parts. I wouldn't choose the PSU based on the length of the cables, I'd go more for a quality unit with a good warranty.

@ justarealguy, nice response!

Ok so the current idea for the ultimate rig will always be just a lean fast system.

All my files are stored on my server so there will be NO hdd's the only reason I can see myself getting more drives is to SSD RAID for a performance boost.

I need more ram 2x2gb

I am going to add a watercooling system as I said, start with CPU only but probably end up cooling whatever I can so no idea on what 4x140mm radiator fans suck in terms of watts and how many pumps i will require (i've not seen more than 2 in a system)

I intend to run another 5770 so I can add another 3 screens to my rig

I'm going to put a fan on my northbridge cooler

and of course I want enough breathing room to replace the GPU's and any other parts with greater power consumption.

What do you think? How much do I need?
post #8 of 20
A good 500w would power your rig with 5770 cf and WC, but I suggest a very good 650w if you ever need anything more powerful than 2 5770, like 2 6970's.

@ Kasp1js, Wow only 650w. so how would someone ever need a 1500w power supply?

btw the XFX looks SWEEET looking. I don't think i'd ever bother sleeving those cables.
post #10 of 20
I personally think a Good quality 850W will be more than enough to power your needs and good for possible upgrades, even a nice 6970 CF setup with a monster overclocked CPU, will hold under a good 850w.
A PSU is the thing you wanna pay for the least, but pay good when you do.

Corsair AX 850 (7yr Warranty)
Silverstone Strider Plus 850 (3yr Warranty)
Seasonic X-850 (5yr Warranty)
XFX 850 Black Edition (5yr Warranty)

[EDIT]:- I forgot to mention, the reason I went for an 850, is 'cos I didn't know what upgrades you may have in the future, 580 SLI will hold under an 850w.
I guess thinking more logically, you'd likely stick with AMD anyway, so a good 650w will be good enough for CF 6970.
However, you won't be left alot of headroom for more HDD's, or different processors, so I'd really suggest a good 750W.
Same brand PSU's, just replace 850 with 750.
