Hey gents, Ive got to do a PSU upgrade and was just wondering what yalls thoughts were. My specs are as follows:

Windows 7 Ultimate 64bit
ASRock Z77 Extreme4
Intel i5-3570k
8GB Ram
AMD Radeon HD 6870
1TB Caviar Black
500GB Seagate External
OCZ-Vertex 30GB Solid State
450w Antec


That PSU was good for my previous build but I have upgraded to the i5, Z77 and the 1TB Internal.

Any other upgrade recommendations would be welcome! (I like my GPU a lot but would be okay to upgrade or do Crossfire with another 6870.)

Thanks!

Hi - You could prob run that sys with the Antec 450,
but I'd upgrade, realhardtech suggests 500w(min 28a on the +12v).

Kinda need to know if you are going to CF down the road as
that not only affects the power requirement but also the # of
PCI-E connectors (yes, you could use molex/pci-e adapters, but
nice not to have to), and your PSU budget.

You might want to upgrade gpu also, for example the 7870 is a significant
performance increase over the 6870

Thanks guys! I need to make a change to that hardware list, its the Extreme4 Not pro 4. I'm pretty sure I want to CF in the future. Id prefer to stay roughly under or around $120. Thanks!

with your set up, two AMD 6870 in CF will have you around 400w total system power, 425w in a stress test

Measured power consumption two 6870 cards

System in IDLE = 184W
System Wattage with GPU in FULL Stress = 421W
Difference (GPU load) = 237W
Add average IDLE wattage x2 ~ 19W (ATI specified)
Subjective obtained GPU power consumption = ~ 275 Watts


http://www.guru3d.com/articles_pages/radeon_hd_6850_687...

for $120 there are a lot of quality 650w that will offer you plenty of power. brands like seasonic, corsair, antec, pc power and cooling, ocz, and xfx are just some of the companies that offer good PSU.

maybe something like the corsair HX650

I think im gonna check that one out. Thanks for the replies guys! I may just go ahead and upgrade the GPU as well like toyftw recommended. Any recommendations out there for that besides the 7870? I looked at the MSI one and that looks pretty solid.

Ah - the hx650 is a good unit, but please be aware that even tho
the overview states that it has 4 pci-e connectors, it has only
2(the discntd model had 4). So, I would not recommend it
for CF for cards needing 2 pci-e each.

Yes, you can use molex to pci-e adapters, but if you are going
to buy a psu to be capable of CF/SLI, might as well get one
with 4 pci-e connectors.

There are several avail @ $120 or less. I'll look for a few in a few min

Hi again - here's a few <$120 that will fit the bill for power & connectors:

http://www.newegg.com/Product/Product.aspx?Item=N82E168... nets to $105

http://www.newegg.com/Product/Product.aspx?Item=N82E168... nets to $95
slightly over:
http://www.newegg.com/Product/Product.aspx?Item=N82E168... nets to $125 ex unit

http://www.newegg.com/Product/Product.aspx?Item=N82E168... nets to $95

http://www.newegg.com/Product/Product.aspx?Item=N82E168... nets to $98

http://www.newegg.com/Product/Product.aspx?Item=N82E168... nets to $80 ex price/value

http://www.newegg.com/Product/Product.aspx?Item=N82E168... nets to $98 ex price - nice modular unit

these are all good PSU's for CF/SLI
