I'm trying to build a mid-end gaming/blu-ray PC at the moment:

I got the following pieces at the moment:

E8500 no OC
Intel GMA 3100
4gb of ram
250gb HDD
asus b-r drive

but here is the issue, right now, i can only drop money on the PSU or the GPU, but right now, i have a Coolmax v-400 that i had purchased as a temporary back up for my main tower below(w/o the hd4870 obviously) that is like 3 months old.

So obvious, their is a bunch of number on the side of the v-400 that i can't freaking understand:
17-159-045-S04


According to some rumors, the GTS450 is sucks around 120w of power out of the PSU.

I used the thermaltake calculator, it came out to around 328w w/ all hardware.

I want a 3rd opinion...as a matter of fact, i want a crap load of opinions before i take the risk of blowing up a $120 gpu.

Should be fine, assuming the PSU isn't a horrible thing that can't manage to output 50% of its rated power.

Edit: looks from price and Newegg reviews like it is a horrible thing for at least some people.

If you can spring $25 then that should do you.

Your system shouldn't use more than about 250w from the wall (more like 200w actual) so you would be fine as long as it's not a POS PSU.
The HD6850 uses more power and I'm running one on my 400w PSU without any issues, max load I've seen is 250w from the wall (with overclocked 6850 and overclocked CPU as in sig).

Myself I wouldn't use it even if I was desperate.

Yeah I looked for reviews and the one I found showed a 600w having less than solid rails (that and the price it goes for).

Stop worrying about your GPU and get a decent PSU first. A bad PSU can wipe out your entire system, including the GPU.

Dude im not bullsh!tting you. You have a 348 watt combined 12 v rail, The gts450 uses 105 watts, e8500 95 watts and another 30 or 40 watts for your hardrive ,fans, and motherboard. Your good.

If you were overclocking your gpu and cpu, I'd start to worry.

Wow, that looks like an awesome PSU. There is only a single 12V rail, so you don't have to worry about distributing load etc.

If i'm gonna dump $ on a PSU, i might as well get this one...

http://www.newegg.com/Product/Produc...82E16817139003

BUT! I'm playing around with online PSU calculators at the moment.

Got 2 putting me @ 310-320w usage with the GTS450.


BUT! Here is a little bit of irony!

With a 5770, all the PSU calculators are putting me around 260-275w
With a 5750, they are putting me around 250-260w~


:hmm:

I'm just wishing i could find the efficiency in this freakin PSU lol...

for some perspective look at my pc. E8500 at 3.8 and old 65nm gtx260 overclocked by quite a bit and I don't hit 300 watts even at the wall during gaming. a gts450 would use about 30-40 watts less so you would no where near the 384watts available on the 12v.

EDIT: even a highly overclocked evga ftw gts450 and i7 only pull 306 watts at the wall. http://www.anandtech.com/show/3909/nvidias-geforce-gts-450-pushing-fermi-in-to-the-mainstream/16

I'm just wondering if it's gonna blow while the GTS450 might be under load...i don't know how far BC2 might push the gts450 @ med/720p

what? I just showed you that even during furmark it is no where near pushing that psu too far even with an i7. your entire setup will never pull more than 250-275 actual watts under full system load.

It pulls a little less wattage when gaming actually, they use a gpu stressing program to stress the card even more then while gaming to get the max wattage for the card.
