GTX 275 + Q8300 on a 450w?

post #1 of 9
Thread Starter 
Hey!

Do you think that my current psu(see my sig) will support my current rig? Well I usually play bad company 2 and black ops for like 5 hours straight on 100% load, and sometimes I download torrents/anime overnight which takes like 8-10 hours straight on idle. Temps on idle stay at 37c and 45c on 100% load. Well I'll only use my current psu for a month because I know that I'll purchase a better psu(probably 600w or more) in the next 1-1/2 months, just to be on the safe side.

So, do you guys think that my 450w can pull off my rig?

~Edit~
And no, im not running on OC or planning to OC until i get the 600w that I'm talking about.

Hell no.

Those Quads are very power hungry unlike the ones today, and adding a GTX 260 or above card will drain even more from the PSU.

I say get one of those Corsair 650W TX PSUs.

I am not familiar with Gigabyte Power supplies, but assuming, and this is a big assumption, but assuming that its actual output is as advertised, you should be fine. Not sure I would want to push the OC on the GPU or CPU all that much though.

Um with that PSU.... that would be pushing it. that PSU isn't exact;y something I would call high quality and I don't think it can even pull its own weight at 450w... Get a new PSU

Look here for an idea as to quality PSUs...

Conclusions
We simply can’t understand why when it comes to power supplies tier 1 motherboard manufacturers prefer to provide low-end products. We’ve seen this happening not only with Gigabyte, but also with MSI and ASUS.

Superb 550P is a decent low-end 450 W unit if you pull between 180 W and 270 W from it, when its efficiency touches 80%. On other load patterns, however, efficiency is too low, preventing us from recommending this unit.

Another thing that counts against this unit is Gigabyte labeling it with its peak power. This, by itself, we think should be illegal everywhere in the world. And to make things worse we couldn’t pull 550 W from it.

Superb 550P is far from being superb and it is too expensive for what it is. For example, you can buy an OCZ StealthXStream 500 W for less and get a far better performance.
Rather pathetic I must say. Read the article and almost puked a little... Your PSU is crap of crap.

Aww.. I guess I'll dig up my old 8500gt hidden somewhere and wait till I get a better psu. Lag.. here I come.

With no o/c, you might be ok, but you'll definitely be close. Fill this out and see for yourself.

That would be the safest course for sure.

edit: Of course you could always try it, and if it works great, if not, then you swap out the vid card, but I still think my original statement stands, you should be fine, just don't push the over clock.

Did some research on your PSU, seems to be a 450watt unit with 550watt's peak. The Q8300 has a TDP of 95watts under full load so it is safe to say that PSU should have no problems keeping up if you keep everything at stock.

Oh, im just going to use this for less than a month because Im going to purchase a TX650 next month. Overclocking aint something im going to do right now because I know my psu cant handle it. So is it really safe to use the 450w for the meantime?
