im still looking in to mini itx cases, and this is the smallest ive seehn by far: http://www.newegg.com/Product/Product.aspx?Item=N82E168.... the antec isk 300-150. would the inluded 150 watt psu be eenough to run a phenom II x4 and a low profile 7750? if not are there psu's made that will fit in this case that will?

More about : 150w phenom 965 7750

simple answer No it will need to be higher. My guess is around 400W or so depending on what you want to add for expansions. you may be able to get away with the 300W but it will be very close. CPU is rated for 125-140W depending on the revision the GPU is rated for 75W. you also need to add case fans CPu fans lights if any HDD's Optical drives. All of this goes towards the total amount of wattage you need.

well ive read in may places, and in previuos posts of mine about other cases and psus that a 275-300w would do. i intend on only having the neccessities plus tthe 7750. a dvd drive, hdd, 4 gigs of ram and the cpu with slim cooler. do you know of a stronger psu for this case?

A good quality 300w psu will run such a system. The problem with you build is itx mobos for AM3 are rare, expensive and not good for OC.

I would also doubt a 300 would cut it unless it was very carefully selected. I know my own 965BE uses over 350 watts (though, that's from the wall) with a 7850 . . . I think even with the 7750 in there you'd probably be pushing 250 from the wall or somewhere near 220 delivered. Even if buying you probably want a decent amount of head room specially if it's not a single rail PSU (IE, dual rail) design since generally the second rail is where the PCI-E connectors go, but the video card would be powered through the motherboard connector . . .

Tread carefully. Plan well . . . or just buy a higher rated PSU.

If the system draws 350w from the outlet and the psu is 90% eff. which is high the system is only 315 from psu . The 7850 is totally different than the 7750 which only uses about 50 watts dull load. The cpu will use more wattage than the 7750. But the Corsair CX430 is only $20 after 20mir at Newegg.

the CX430 will NOT fit in the case he has selected. he has chosen a M-itx form factor.

Antec site has no info on psu size. Contac Antec to see if it's a SFX psu.

Except of course for the fact that the CPU alone (including the rest of the PC, just doing nothing with video) running Prime 95 draws about 150 watts from the wall, so I very much doubt his 150 is going to cut it, and even if he gets something like a 250 or 300 unless it's a single rail design may not do it either since the power may likely be all drawn from one rail considering the video card has no PCI-E connector. So depending on the PSU design a dual rail 300 may not even cut it once the video card gets moving too.

If you intend on basic Office applications you might get away with a lower PSU but if you intend on gaming then this type of case is not suited to you.

This case makes more sense for a AMD a10 build.

. . . or any Intel build since then you get performance and efficiency.
