• Good GPU for tiny power supply?
    16 replies, posted
I had the misfortune of receiving a pre-built computer for my birthday last year. It was a rather decent computer, with a 9800GT(512MB version), 4GB of RAM, and an Intel E7500 @ 2.93Ghz, however I'm looking to upgrade my graphics card. I have 1x PCI-E 2.0 16x slot available. Here's the problem. Dell has the nasty habit to toss in a shit, 350W power supply. Also the case is rather small and I can't have the card be too big otherwise it won't fit (I'm not sure the dimensions of a 9800GT) I can't upgrade the power supply because Dell basically welds that shit in there. I can't find any on Newegg with a power requirement of less than 400. Has anyone in my situation known a solution? My budget would be $125 maximum, although if it's worth it I can go up to 150.
You can't really get much better than a 9800GT with a 350W PSU and $125 [editline]f[/editline] Honestly your entire computer is just mediocre and there would be little use upgrading one component

[QUOTE=anikilol;20624662]This ^ Save up to 200 and get a 5770 and a $40 coolermaster PSU[/QUOTE] Can't, the PSU is pretty much welded to the back there. I can't seem to get it out regardless.

He can't screw it out. It's a specially designed Dell PSU that cannot be removed.
What model is it
Oh dell.....
Sell the whole computer + collect a fund for a new, custom build.

Graphics card companies overestimate watt usage to be sure. The 5770 requires 450 watt, but in reality it won't use much more then 255: [IMG]http://i.neoseeker.com/a/hd5750hd5770/powerbar.png[/IMG] I'm putting one on my 425 power supply. If it's only 25-50 watt over I wouldn't really worry.
It's not just the overall Wattage you have to look at. So it claims to have a 420W total output, but how is that distributed? For example, if Zemog has a PSU labelled as 420W, it could well have very low Amperage on the 12 V rail(s) and not be able to power a 5770 at all, as is often the case with cheap units. The other scenario is that it's a high quality unit and would probably have no problem powering a 5770.

150 isn't enough for a decent upgrade on the GPU anyway.

That being said, you can probably run a 5770 on a 400w granted its a quality PSU.

Why? How do you know your PSU isn't a crappy one?
