Will the OCZ ModXStream 400w be sufficient?

[spleenharvester]

Hi,
I have:
PNY 8800gt 256mb
AMD Athlon X2 5000+ undervolted (1.35v to 1.125v)
2 sticks of DDR2-5300
Asus M3A (also known as M3A-770)
Pioneer DVR-1120 IDE
Western Digital WD1600AAJS 160gb Sata 300
Abit AirPace wireless card
7 USB devices (max)
4 case fans

I currently have an X-Power GTX Lite 580, great stable PSU, but a bit on the noisy side (I'm heading for a 17db PC, this is 25db). I was tempted to change the fan but... parents, you see
The Xtreme Outervision PSU calculator says I can cope fine with 270w, however this seems incredibly low for an 8800gt? Will this PSU do? I might stretch for the 500w, but I'm really on a budget here. Thanks.

but changing the fan on the PSU u have would also be a good idea

Was looking at that PSU before. It does look good, but I'd prefer modular, as my Jeantech R2 is about 11cm shorter than a normal case and is a pain in the ass to work with.

This, but if you want to go modular, you would be more than fine with This.

A 400W PSU would be fine for that spec - it's never going to draw more than about 200W. Personally I prefer the Corsair but the OCZ should be OK.

Only if you know what you're doing. The components in a PSU can store electricity even when it's unplugged, so it can be quite dangerous to open one up.

If thats the right you might want to check the size of he case/card to see if it fits your case.
