So yea, I have a ACBell Power Supply (It came with a pre-built HP System), and I'am wondering if I can throw a ATI HD 7850 in here, as it says that requires at least 500W.

This is my power supply info.

ACBELL
MODEL: API5PC67
CUSTOMER ID: 021G
HP P/N :5188-2863
AC INPUT :100-240V~9A, 50-60Hz
DC OUTPUT:
+ 5.0V ---- 13.0A
+ 3.3V ----17.0A
+12.0Va ----16.0A ------------------------------------------|
+12.0Vb ----15.0A ---- TOTAL 385W @50ºC MAX -----|
+12.0Vc ---- 8.0A -------------------------------------------|
+ 12.0V ---- 0.8A
+ 5.0Vstb ---- 2.0A
TOTAL 460W @ 50ºC MAX
TOTAL 360W @ 60ºC MAX

Thanks.

As It Says, At Least A 500w. It Will Probably Run, But I Recommend Upgrading :)

maybe yes, maybe not..

depend on rest of your system..

it will help if you can list all of your component..

If the PSU is ok, and works at it's rated values, it should be fine. But that is a big IF, for a brand I've never heard of. I would suggest getting a quality power supply (Seasonic, XFX, Corsair, PC Power & Cooling to name a few) to be on the safe side, but what you have will probably work. If you have any stability issues though, the PSU would be top of the list for problems.

Yea, i dont know the psu brand but I think its okay, and yea, I will probably get the 7850 on christmas and if i get stability issues it will be PSU related :) 

Thanks for the answers :)

according to this review with system below..

Processor = Intel Core i7-3960X
Motherboard = ASUS P9X79 Deluxe
Memory = 16GB Corsair 1866MHz
Solid-State Drive = OCZ Vertex 3 240GB

and this is the power consumption


*taken from http://www.legitreviews.com/article/1863/12/

You can see that the system equipped with 7850 just need 253 watt in furmark..worst scenario in vga power consumption..

still plenty room for your psu..

well..
go for it..your psu will serve your needs..

Acbell is relatively good psu, known brand from long time..at least it's a real power psu..not the fake one..:)

I just like, love u right now :p 
Thank you !

Go here Extreme PSU Calculator and input everything you have, case fans, hdd's, everything. Take the total and add 20% for headroom. That's your wattage.

For my system (read sig) it states:
Minimum PSU Wattage: 283 W
Recommended PSU Wattage: 333W + 20% Headroom = 399W

That is one hell of a cool link, thanks :p

No problem, always here to try and help.

Edit: you can change your video card to the one you want and recalculate the wattage. Save you some hassle.

Edit #2: I'll be switching to an i5-3570K & Radeon 7950 soon. All I did was change my i3 to an i5, input the overclocked speed (conservative 4.4ghz) and switched the 6850 to the 7950 and recalculated.

Now I'm at
Minimum: 355W
Recommended: 405W
+ 20%: 486W

So according to that I could run those upgrades (405W recommended) with my current 450W 36A PSU but I SHOULD upgrade to at least 500W (486W headroom). Saved me a lot of hassle.

Cool, just used that link and I got a minimum of 334W and 384W recommended so I am perfectly fine :D 

EDIT: Would there be a big of a difference between the Sapphire HD 7850 1GB and the 2GB model? Would I get a big performance impact?
Thanks.

actually, PSU calculator is not accurate..

just give you quick and dirty information of power that you need..

Give the safest point that you might go..and that's always means bigger than you really need..

Don't rely on it too much.. :D

at 1920 and below, there's no differences between 1gb and 2gb gpu memory..
if your monitor at 1920 or below it, pick 1gb card..

but

if you play at 2500, go with 2gb..


save your money..:)

yes, that makes alot of sense, my monitor is 1680 x 1050 so its no big deal the 2gb model for me :D 

Thanks im happy and excited now :p

That's why I said to add in the 20%. That takes into account any flaws in their calculations.

Per AMD: "500W (or greater) power supply with two 75W 6-pin PCI Express power connectors recommended" for the 7950. By adding the 20% to their calculations I came up with 486W, basically 500W. Notice I also said "at least".

Their calculator is about 20% shy of being accurate. So take their recommended, add 20% and you get your true minimum.
