Windows 7: Isn't 300W too little??

Isn't 300W too little??

I will be getting this PC soon:
HP Pavilion p6565uk Desktop PC Product Specifications HP
And while waiting for it to arrive, I have been looking over the specs sheet over and over. When I first read through it, it struck me as odd that the PSU was only 300W. For a computer with 6GB DDR3, 6 cores, a blu ray reader and a 1.5GB GPU, surely this is too little? The instruction manual with my Nvidia 8400GS, it said have a 300W minimum PSU (and that card only had 512MB vRAM). Yes, I know that the RAM isn't a main factor, but still, isn't 300W too little??

(Yes, I did want to build another rig, to re-strengthen my faith in my capabilities of doing so (some of you may remember that the motherboard on my last rig shorted by itself), but this PC was cheaper than it would cost to build one with worse specs (or so Custom PC magazine showed http://images.bit-tech.net/issues/20...ustompc-95.jpg ). Looks like I'll just have to wait a bit longer to build my dream rig. I will probably also be wanting to mod this a bit, e.g. get it up to the 16GB RAM max, add some more HDDs, so I do hope that despite it being a microATX board that the case will still fit normal size PSUs (as my last case didn't. Well, it did if I could go without an optical drive, which I couldn't).

You should be able to fit a normal PSU because the case is listed as being a mid-tower. If it really is, then it's a normal size PSU, as the only small ones are the ones for slimlines and some small media centers.

If you upgrade the RAM, etc, I would consider a 500W power supply, but stock it should run just fine.

I have a dead standard-size PSU lying around (don't ask why, well, y'know the US/EU voltage switch on the back? Don't switch it while it's on ), so I'll check the sizes as soon as it arrives.

Be sure to hang on to the old one(PSU) in case of warranty repairs, also be prepared to return the system to stock.....

ah yeah, thanks for reminding me (yeah, it has a 12 month warranty, and I don't particularly trust HP machines to run as smoothly as possible )
(I'll 'spread around some rep' and then get back to you, as you were the last last person I gave rep to )

Most people buy power supplies that are too large. I'm sure a prebuilt computer has enough power...if not...it's warrantied.

if you plan to play games on this pc you will need to change graphics card because this one is .. very very slow for games. GT230 is low economy class GPU, in this case with overload of VRAM.. that amount will never be useful for such slow GPU. (maybe 512 or so its good match for this GPU)
It's fine to watch movies etc play simple games but not for more demanding games.
I think its marketing trick GB, GHz etc.. from old times (geforce first maybe second generation time) vga was judged by its VRAM MB, and cpu by clock speed MHz.

to answer your question yes for this build 300w psu is ok. tought there is almost no spare power (a bit more RAM one more HDD may be fine, but not better vga).
and if you plan to upgrade components you will need new PSU

Yeah, I had a feeling that that card wasn't too great, as yeah, they tried to hide it's real specs behind the large vRAM label
I've got an Nvidia 8400GS with 512MB vRAM knocking around in a cupboard, would that be better than the GT230? (or should I just buy a better graphics card straightaway )
